DESCRIPTION OF THE EMBODIMENTS

(10) Hereinafter, embodiments will be described in detail with reference to the attached drawings. Note, the following embodiments are not intended to limit the scope of the claimed invention. Multiple features are described in the embodiments, but limitation is not made of an invention that requires all such features, and multiple such features may be combined as appropriate. Furthermore, in the attached drawings, the same reference numerals are given to the same or similar configurations, and redundant description thereof is omitted.

(11) Note that a multi function peripheral (digital multi-function peripheral/MFP) will be described as an example of an image formation apparatus according to the embodiment. However, a scope of application is not limited to a multi function peripheral and may be any image formation apparatus comprising a printing function.

System Configuration

(12) Hereinafter, an embodiment of the present invention will be described. First, with reference to FIG. 1, a commercial printing system configuration according to the present embodiment will be described. This commercial printing system is configured comprising a workflow management server 100, a workflow management terminal 101, an order reception system server 110, an order reception system management terminal 111, an end user terminal 112, a production system (printing system) 120, and a production operator terminal 125.

(13) The workflow management server 100 is an apparatus for managing an overall workflow related to commercial printing goods. The workflow management server 100 receives PRX data, which is print data and quality condition information, from the order reception system server 110. The PRX stands for a print requirement exchange format and indicates a standardized data format for quality conditions required for printing. The PRX has been considered as a standardization technology in order to unify the information format for transmitting quality conditions. By using the PRX, the quality conditions for different customers or different orders can be written in a unified and standardized data format. As described above, quality conditions which were conventionally not unified will be enabled for transmission in a unified information format using the PRX.

(14) By using the PRX that describes the quality conditions that customers are seeking, the operation process performed when producing print products for satisfying the quality conditions and the operation process for checking the quality of the print products can be established in a printing system without an intervention by the operator. In other words, presetting of printing apparatuses and software can be performed automatically. Then, the workflow management server 100 interprets the PRX data received from the order reception system server 110, and then for every order job, decides the production system 120, executes print data prepress processing, and such. Also, the workflow management server 100 generates data (print data, job ticket, operation setting information, control instruction, etc.) to be processed in the production system 120 then sends it to each device comprised by the production system 120. As for devices comprised by the production system 120, they will be described later. Note that in the present embodiment, the workflow management server 100 is described with an assumption that it is an on-premises server placed at a site that performs workflow management; however, limitation is not made to this. As another embodiment, the workflow management server 100 may be configured to be constructed as a cloud server then be connected via the Internet from the workflow management terminal 101 described later. The same applies to the order reception system server 110 described later. Note that in the present embodiment, the workflow management server 100 is described with an assumption that it executes a PRX interpretation and print data preflighting (pre-print data check); however, limitation is not made to this. As another embodiment, the execution may be performed by the order reception system server 110 described later or a print server 122 of the production system 120 described later.

(15) The workflow management terminal 101 is a terminal that is operated by a workflow administrator that executes various functions by connecting to the workflow management server 100 via a network, and that receives and displays information from the workflow management server 100. More specifically, the workflow management terminal 101 changes a workflow management function setting, confirms a state of the production system 120 device, displays information related to the inconsistency between the print data and the PRX, and such. An order reception system server (order intake server) 110 is an apparatus for managing a system for receiving orders from an end user related to commercial printing goods. The order reception system server 110 generates print data and a PRX based on product for which an order is received or the content of orders from an end user then sends them to the workflow management server 100.

(16) The order reception system management terminal 111 is a terminal operated by an order reception system administrator and connects to the order reception system server 110 via a network, and then executes each function. The functions comprise functions for setting a goods-specific requested quality, confirming the status for every order job, and viewing product quality information for every order job, and the like The end user terminal 112 is a terminal operated by an end user and connects to the order reception system server 110 via a network. Then, via a UI such as a web browser, instructions such as a goods selection, document data transmission, or order placement from an end user is accepted then sent to the order reception system server 110.

(17) The production system 120 is a system for producing goods (products) in commercial printing. Specifically, the production system 120 is configured comprising a printing apparatus 121 and the print server 122. Note that although the invention is explained here with such a configuration as an example of a production system, there is no intent to limit the invention. For example, the present production system may be configured comprising another apparatus or may be configured so that the printing apparatus comprises all apparatuses. The printing apparatus 121 is an apparatus for executing printing processing based on data and an instruction from the workflow management server 100. No particular limitation is made to a printing method, and the method may be an electrographic method, an inkjet method, or any other method. An administrator or an operator of the production system 120 is able to instruct control related to printing via a UI of the printing apparatus 121. The print server 122 is a server for controlling the printing apparatus 121. Similarly to a typical printing system, the administrator or the operator of the production system 120 is able to instruct control related to printing via an UI of the print server 122. The production operator terminal 125 is an apparatus used by the operator who operates all sorts of devices of the production system 120 described above. The apparatus comprises functions such as confirming the operation state of devices or confirming error information when an error occurs. As another form, a configuration may be taken so that a UI operation unit comprised by each device rather than an external terminal is responsible for these functions.

Hardware Configuration of Each Apparatus

(18) Next, with reference to FIG. 2, a hardware configuration of each apparatus according to the present embodiment will be described. FIG. 2 illustrates a hardware configuration of a workflow management system comprising the workflow management server 100 and the workflow management terminal 101 according to the present embodiment.

(19) First, a hardware configuration of the workflow management server 100 will be explained. The workflow management server 100 comprises a CPU 201, a ROM 202, a RAM 203, an HDD 204, and a network I/F 205. The CPU 201 deploys in the RAM 203 a control program stored in the ROM 202 or the hard disk (HDD) 204, executes that deployed program, and collectively controls access to all sorts of devices connected to a system bus 206. The ROM 202 stores, for example, the control program that the CPU 201 is able to execute. The RAM 203 mainly functions as a main memory, a work area, or the like, of the CPU 201 and is configured such that a memory capacity can be extended by an option RAM 203 connected to an expansion port (not shown). The hard disk drive (HDD) 204 stores a boot program, all sorts of applications, font data, a user file, and an edit file. Note that although the HDD 204 was used in the present embodiment, an SD card, a flash memory, an SSD, an eMMC, or the like may be used as an external storage unit besides the HDD. The same applies to apparatuses comprising an HDD described hereinafter. The network I/F 205 performs data communication with all sorts of apparatuses, which are external apparatuses, via the network. Note that because the hardware configuration in a case where the order reception system server 110 is the same as that of the workflow management server 100, the description will be omitted.

(20) Next, a hardware configuration of the workflow management terminal 101 will be explained. The workflow management terminal 101 comprises a CPU 211, a ROM 212, a RAM 213, an HDD 214, and a network I/F 215. The CPU 211 deploys in the RAM 213 a control program stored in the ROM 212 or the hard disk (HDD) 214, executes that deployed program, and collectively controls access to all sorts of devices connected to a system bus 216. The ROM 212 stores, for example, the control program that the CPU 211 is able to execute. The RAM 213 mainly functions as a main memory, a work area, or the like, of the CPU 211 and is configured such that a memory capacity can be extended by an option RAM 213 connected to an expansion port (not shown). The hard disk drive (HDD) 214 stores a boot program, all sorts of applications, font data, a user file, and an edit file. The network I/F 215 performs data communication with other apparatuses via the network. Note that because the hardware configuration of other terminal apparatuses such as the order reception system management terminal 111, the end user terminal 112, and the production operator terminal 125 are the same as that of the workflow management terminal 101, the description will be omitted.

(21) Next, a hardware configuration of the production system 120 will be explained. The production system 120 is configured comprising the printing apparatus 121 and the print server 122 as described above. The printing apparatus 121 comprises an image formation unit. Also, the print server 122 comprises a CPU 221, a ROM 222, a RAM 223, an HDD 224, and a network I/F 225.

(22) The CPU 221 deploys in the RAM 223 a control program stored in the ROM 222 or the hard disk (HDD) 224, executes that deployed program, and collectively controls access to all sorts of devices connected to a system bus 226. The ROM 222 mainly stores, for example, the control program that the CPU 221 is able to execute. The RAM 223 mainly functions as a main memory, a work area, or the like, of the CPU 221 and is configured such that a memory capacity can be extended by an option RAM connected to an expansion port (not shown). The hard disk (HDD) 224 stores a boot program, all sorts of applications, font data, a user file, and an edit file, and the network I/F 225 performs data communication with other apparatuses via the network.

(23) A printer I/F 227 controls an image output of the printing apparatus 121 to an image formation unit 228. The image formation unit 228 outputs print data on a sheet. Note that the printing apparatus 121 may comprise a post-processing apparatus for performing stapling processing or folding processing to a print product outputted by the image formation unit 228 or an inspection apparatus for performing an inspection of the print product.

Software Configuration of Workflow Management Server

(24) Next, an example of a software configuration of the workflow management server 100 according to the present embodiment will be explained with reference to FIG. 3. These software modules are stored in the HDD 204 as programs and are implemented by the CPU 201 deploying and executing the programs in the RAM 203.

(25) The workflow management server 100 comprises a data management unit 301, an integrated control unit 302, a PRX interpretation unit 303, and a prepress processing unit 304 as a software configuration. The data management unit 301 receives the print data and the PRX data from the order reception system server 110. It also executes a rewriting of the PRX and a storing of a change log of the PRX in the HDD 204 which are described later. The PRX interpretation unit 303 analyzes the PRX data received from the order reception system server 110, and then specifies a printing quality condition for the print job. Results obtained from the analysis by the PRX interpretation unit 303 are described later. The prepress processing unit 304 analyzes the print data of the print job. Results obtained from the analysis by the prepress processing unit 304 are described later. The integrated control unit 302 reads a PRX analysis result of the PRX interpretation unit 303 and a print data analysis result of the prepress processing unit 304, and then compares the PRX and print data analysis results to determine whether there is any inconsistency. In the present embodiment, as described in detail below, an example in which if an object corresponding to the print job quality requirement data (PRX) comprising the print image does not exist in the print data, it is determined to be inconsistent will be described. However, this is an example for explaining the invention, and other determination criteria may be used to determine inconsistencies.

(26) Note that in the present embodiment, the workflow management server 100 is described with an assumption that it comprises the PRX interpretation unit 303 and the prepress processing unit 304 that executes print data preflighting; however, limitation is not made to this. As another embodiment, the order reception system server 110 or the print server 122 of the production system 120 may comprise these software configurations.

PRX Analysis Results

(27) Next, the PRX analysis result by the PRX interpretation unit 303 according to the present embodiment will be explained with reference to FIG. 4. FIG. 4 indicates an example of a parameter in which quality requirements related to an object in the print data are described. An object in the print data indicates a predetermined image comprised in the print image if printed according to the print data. For example, it is a corporate logo, a barcode, or the like comprised in the print image. The PRX interpretation unit 303, as described below, extracts necessary portions from the PRX, and then performs an analysis.

(28) 4a of FIG. 4, as an example related to colors, illustrates a case where the end user has specified a quality requirement regarding a spot color defined as “SpotColorRed” using the PRX. ColorParameter is configured from a field which defines a parameter for a quality requirement related to colors. ParameterName represents a name of the quality requirement. SamplingPosition represents position information of an object in the print data, and here, the position information is represented by SamplingPositionMatrix which is a coordinate value in the print data. ChartType represents a category of a color chart to reference for when measuring a color. CxFReferenceObjectIdLink uses an ID to represent a link to a data set which represents target color information of the object. FIG. 5 illustrates a data set associated by CxFReferenceObjectIdLink, and the color information associated with CxFReferenceObjectIdLink=CxF002 is ObjectName=“2”.

(29) 4b of FIG. 4, as an example related to barcodes, illustrates a case where the end user has specified a quality requirement regarding a barcode defined as “QRcode” using the PRX. BarcodeParameter represents a name of a quality requirement related to a “barcode”. BarcodeSymbology represents a barcode type of an object. SamplingPosition represents position information of an object in the print data, and here, an object image information data set is represented by SamplingPositionImageIdLink which is an ID. FIG. 6 is a data set associated by SamplingPositionImageIdLink. The image information associated with SamplingPositionImageIdLink=BC2 is “barcode.pdf”.

(30) Also, as a result of analyzing the print data in the prepress processing unit 304, in a case of a spot color, the position information, name of the spot color, and a Lab value of the object can be obtained. Also, in a case where a barcode is embedded as a font, a barcode type can be obtained by a barcode font. In a case of barcode objects, the barcode type can be obtained by a tag associated with the object.

Color: Comparing Print Data Analysis Result Corresponding to PRX Analysis Result

(31) Next, a processing procedure of the workflow management server 100 according to the present embodiment will be explained with reference to FIGS. 7A-7B. First, processing for comparing the PRX and print data analysis results for a case where there is a quality requirement description for the object related to the “color” illustrated in 4a of FIG. 4 in the PRX will be explained. The processing explained below is achieved, for example, by the CPU 201 of the workflow management server 100 reading and then executing a control program stored in the ROM 202 or the HDD 204 on the RAM 203. Also, the present flowchart starts the processing when the data management unit 301 receives the PRX and print data from the order reception system server 110.

(32) In step S701, the integrated control unit 302 sends the print data received by the data management unit 301 to the prepress processing unit 304, and then sends the PRX to the PRX interpretation unit 303. The prepress processing unit 304 analyzes the print job (print data), and then sends the analysis result to the data management unit 301. In step S702, the PRX interpretation unit 303 analyzes the PRX, and then sends the analysis result to the data management unit 301. Then, in step S703, the integrated control unit 302 reads the PRX analysis result from the data management unit 301 that received the print data and PRX analysis results, and then determines whether there is a quality requirement standard. Specifically, the integrated control unit 302, by determining whether there is a ColorParameter description in the PRX analysis result, determines whether there is a description of the quality requirement standard regarding the color for the object in the print data.

(33) In a case (S703: N) where it is determined that there is no description of the quality requirement standard, the processing of the present flowchart ends. On the other hand, in a case (S703: Y) where it is determined that there is description of the quality requirement standard, the processing proceeds to S704. In step S704, the integrated control unit 302 determines whether the object corresponding to the quality requirement standard indicated by the PRX which was analyzed in step S702 is comprised in the print data analyzed in step S701. Specifically, the integrated control unit 302 reads the PRX analysis result (ColorParameter) from the data management unit 301 then obtains the content of that ColorParameter. Also, the integrated control unit 302 obtains the target color information ID indicated by CxFReferenceObjectIdLink in ColorParameter then obtains the Lab value in CxFReferenceData associated with the ID. That is, the integrated control unit 302 obtains a parameter such as the color information and position information of the object related to the quality requirement standard of color from the PRX. Additionally, the integrated control unit 302 reads the print data analysis result then obtains the color information Lab value of the corresponding object. Additionally, the integrated control unit 302, by performing a comparison of the PRX analysis result Lab value and the Lab value of the corresponding object from the analysis result of predetermined location of the print data, performs the above determination. Here, the predetermined position, for example, indicates a position indicated by the position information of the object (target of a spot color) assigned by the above SamplingPosition in the PRX of an image of the object in the print image formed when printed. In other words, whether or not print data corresponding to the target object in the position assigned by the PRX is present is determined.

(34) In a case (S704: Y) where the compared results match and it is determined that the object corresponds, in other words, it is determined that there is no inconsistency between the PRX which is the quality requirement standard and the print data, then the processing of the present flowchart ends. On the other hand, in a case (S704: N) where the object is determined to not correspond, in other words, in a case where there is an inconsistency between the PRX which is the quality requirement standard and the print data, the processing advances to step S705, then the integrated control unit 302 gives a warning to the operator about the inconsistency. Specifically, the integrated control unit 302 sends the PRX analysis result for the inconsistent object from the data management unit 301 to the workflow management terminal 101. The workflow management terminal 101 displays a warning screen 810 illustrated in FIG. 8 on a display unit of the workflow management terminal 101. The warning screen 810 displays “stop print job” 801 and “continue print job” 802 so the operator of the workflow management terminal 101 can select them. Next, in step S706, the integrated control unit 302 determines whether to temporarily stop the processing of the print job, in other words, whether or not “stop print job” 801 was selected via the warning screen 810.

(35) In a case (S706: Y) where “stop print job” 801 is selected, the processing advances to step S707, and the integrated control unit 302 pauses the print job processing, displays a screen 820 illustrated in FIG. 8 indicating that the PRX needs to be revised, then ends the processing of the present flowchart. On the other hand, in a case (S706: N) where “continue print job” 802 is selected, the processing advances to step S708, and the integrated control unit 302 compares the Lab value of the PRX analysis result obtained in step S704 and the Lab value of each object in the print data analysis result by the data management unit 301. Additionally, the integrated control unit 302 searches whether or not an identical object is present in a different location of the print data as a result of a comparison.

(36) In a case (S708: N) where there is no identical object, the processing advances to step S709, and the integrated control unit 302 reads the PRX analysis result of the data management unit 301, discards the PRX corresponding to the object in which inconsistency is occurring, then ends the present flowchart processing. On the other hand, in a case (S708: Y) where there is an identical object, the processing advances to step S710, and the integrated control unit 302 notifies the workflow management terminal 101 that there is an identical object in a different position of the print data. The notification may be displayed in a confirmation screen 830 which will be displayed next or temporarily displayed in a pop-up screen then transition to be displayed in the confirmation screen 830. Next, in step S711, the integrated control unit 302 displays a PRX position information rewrite confirmation screen 830 illustrated in FIG. 8 on the display unit. The confirmation screen 830, as illustrated in FIG. 8, displays “rewrite PRX position information” 803 and “do not rewrite PRX position information” 804 so that they can be selected and also displays a modified position 805 of the object if the PRX position information is rewritten. The modified position 805 illustrates that a position (dashed-line) of the object indicated by the PRX will be changed to a position (where the arrow points) of the object that corresponds to the print data. The operator of the workflow management terminal 101 can confirm the modified position 805 and then select whether or not to rewrite the PRX. In step S712, the integrated control unit 302 determines whether or not the operator of the workflow management terminal 101 has selected to rewrite the PRX position information.

(37) In a case (S712: N) where “do not rewrite PRX position information” 804 is selected, the processing advances to step S709, and the integrated control unit 302 reads the PRX analysis result of the data management unit 301, discards the PRX corresponding to the object in which inconsistency is occurring. Then, the processing of the present flowchart is ended. On the other hand, in a case (S712: Y) where “rewrite PRX position information” 803 is selected, the processing advances to step S713, and the integrated control unit 302 rewrites the PRX position information. Specifically, the integrated control unit 302 reads the PRX analysis result of the data management unit 301 then obtains the position information, for example, the location, (X, Y)=(112, 200), of the identical object in the print data detected in step S708. Additionally, the integrated control unit 302 rewrites SamplingPosition, which is the original data in 4a of FIG. 4 as illustrated in 9a of FIG. 9. Note that the integrated control unit 302 does not need to obtain the position information again in step S713 if it has previously obtained the PRX or print data position information in order to display the modified position 805. Next, in step S714, the integrated control unit 302 associates the history of the PRX that has been changed in the sequence of operations with the print data, stores it in the HDD 204, then ends the processing of the present flowchart.

Barcode: Comparing Print Data Analysis Result Corresponding to PRX Analysis Result

(38) Next, processing for comparing the PRX and print data analysis results for a case where there is a quality requirement description for the object related to the “barcode” illustrated in 4b of FIG. 4 in the PRX will be explained, once again with reference to the flowchart in FIGS. 7A-7B. The processing explained below is achieved, for example, by the CPU 201 of the workflow management server 100 reading and then executing a control program stored in the ROM 202 or the HDD 204 on the RAM 203. Also, the present flowchart starts the processing when the data management unit 301 receives the PRX and print data from the order reception system server 110.

(39) In step S701, the integrated control unit 302 sends the print data received by the data management unit 301 to the prepress processing unit 304, and then sends the PRX to the PRX interpretation unit 303. The prepress processing unit 304 analyzes the print job (print data), and then sends the analysis result to the data management unit 301. In step S702, the PRX interpretation unit 303 analyzes the PRX, and then sends the analysis result to the data management unit 301. Then, in step S703, the integrated control unit 302 reads the PRX analysis result from the data management unit 301 that received the print data and PRX analysis results, and then determines whether there is a quality requirement standard. Specifically, the integrated control unit 302, by determining whether there is a BarcodeParameter description in the PRX analysis result, determines whether there is a description of the quality requirement standard regarding the barcode object in the print data.

(40) In a case (S703: N) where it is determined that there is no description of the quality requirement standard, the processing of the present flowchart ends. On the other hand, in a case (S703: Y) where it is determined that there is description of the quality requirement standard, the processing proceeds to S704. In step S704, the integrated control unit 302 determines whether the object corresponding to the quality requirement standard indicated by the PRX which was analyzed in step S702 is comprised in the print data analyzed in step S701. Specifically, the integrated control unit 302 reads the PRX analysis result (BarcodeParameter) from the data management unit 301 then obtains the barcode type and SamplingPosition information of the object indicated by Barcode Symbology. That is, the integrated control unit 302 obtains a parameter such as the barcode type and position information of the object related to the quality requirement standard of barcode from the PRX. Additionally, the integrated control unit 302 reads the print data analysis result and in a case where the barcode is embedded in a font, barcode type is obtained by classifying the barcode font. In a case where barcodes are object images, the barcode type can be obtained by a tag associated with the object. The obtained PRX barcode type and the print data barcode type are compared. Here, similarly to the description of example in 4a of FIG. 4, whether or not the print data that corresponds to the target object (barcode in the corresponding type) is present in the position assigned by the PRX is determined.

(41) In a case (S704: Y) where the compared results match and it is determined that the object corresponds, in other words, it is determined that there is no inconsistency between the PRX which is the quality requirement standard and the print data, then the processing of the present flowchart ends. On the other hand, in a case (S704: N) where the object is determined to not correspond, in other words, in a case where there is an inconsistency between the PRX which is the quality requirement standard and the print data, the processing advances to step S705, then the integrated control unit 302 gives a warning to the operator about the inconsistency. Specifically, the integrated control unit 302 sends the PRX analysis result for the inconsistent object from the data management unit 301 to the workflow management terminal 101. The workflow management terminal 101 displays the warning screen 810 illustrated in FIG. 8 on a display unit of the workflow management terminal 101. The warning screen 810 displays “stop print job” 801 and “continue print job” 802 so the operator of the workflow management terminal 101 can select them. Next, in step S706, the integrated control unit 302 determines whether to temporarily stop the processing of the print job, in other words, whether or not “stop print job” 801 was selected via the warning screen 810.

(42) In a case (S706: Y) where “stop print job” 801 is selected, the processing advances to step S707, and the integrated control unit 302 pauses the print job processing, displays the screen 820 illustrated in FIG. 8 indicating that the PRX needs to be revised, then ends the processing of the present flowchart. On the other hand, in a case (S706: N) where “continue print job” 802 is selected, the processing advances to step S708. In step S708, the integrated control unit 302 compares BarcodeSymbology, which is the PRX analysis result barcode type that has been obtained in step S704, and the barcode type of each object of the print data analysis result of the data management unit 301. Additionally, the integrated control unit 302 searches whether or not an identical object is present in a different location of the print data as a result of a comparison.

(43) In a case (S708: N) where there is no identical object, the processing advances to step S709, and the integrated control unit 302 reads the PRX analysis result of the data management unit 301, discards the PRX corresponding to the object in which inconsistency is occurring, then ends the present flowchart processing. On the other hand, in a case (S708: Y) where there is an identical object, the processing advances to step S710, and the integrated control unit 302 notifies the workflow management terminal 101 that there is an identical object in a different position of the print data. The notification may be displayed in the confirmation screen 830 which will be displayed next or temporarily displayed in a pop-up screen then transition to be displayed in the confirmation screen 830. Next, in step S711, the integrated control unit 302 displays the PRX position information rewrite confirmation screen 830 illustrated in FIG. 8 on the display unit. The confirmation screen 830, as illustrated in FIG. 8, displays “rewrite PRX position information” 803 and “do not rewrite PRX position information” 804 so that they can be selected and also displays the modified position 805 of the object if the PRX position information is rewritten. The modified position 805 illustrates that a position (dashed-line) of the object indicated by the PRX will be changed to a position (where the arrow points) of the object that corresponds to the print data. The operator of the workflow management terminal 101 can confirm the modified position 805 and then select whether or not to rewrite the PRX. In step S712, the integrated control unit 302 determines whether or not the operator of the workflow management terminal 101 has selected to rewrite the PRX position information.

(44) In a case (S712: N) where “do not rewrite PRX position information” 804 is selected, the processing advances to step S709. In step S709, the integrated control unit 302 reads the PRX analysis result of the data management unit 301, discards the PRX corresponding to the object in which inconsistency is occurring, then ends the present flowchart processing. On the other hand, in a case (S712: Y) where “rewrite PRX position information” 803 is selected, the processing advances to step S713, and the integrated control unit 302 rewrites the PRX position information. Specifically, the integrated control unit 302 reads the PRX analysis result of the data management unit 301 then obtains the position information, for example, PositionLocationImage Id=“QR1” in FIG. 6B, of the identical object in the print data detected in step S708. Additionally, the integrated control unit 302 rewrites SamplingPosition, which is the original data in 4b of FIG. 4 as illustrated in 9b of FIG. 9. Note that the integrated control unit 302 does not need to obtain the position information again in step S713 if it has previously obtained the PRX or print data position information in order to display the modified position 805. Next, in step S714, the integrated control unit 302 associates the history of the PRX that has been changed in the sequence of operations with the print data, stores it in the HDD 204, then ends the processing of the present flowchart.

(45) As described above, the information processing apparatus according to the present embodiment interprets the quality requirement data of a print job received externally, analyzes the print data of the print job, then compares the interpretation result of the quality requirement data and the analysis result of the print data. Also, in a case where an object comprised in the print image corresponding to the quality requirement data of the print job is not present in the print data as a result of the comparison, the information processing apparatus displays the warning screen on the display unit. Additionally, whether to stop or continue executing the print job is displayed in the warning screen so the operator of the information processing apparatus can select them. Consequently, by virtue of the present embodiment, the inconsistencies between the quality conditions specified for the print job and the corresponding print data can be detected then warned about. Also, the operator is able to select a subsequent response, thereby enabling to provide a user-friendly operation system.

(46) The present invention is not limited to the foregoing embodiments, and various variations are possible. For example, in the above embodiment, an example was given where the PRX is used as a data format for conveying the quality requirement content of print data; however, there is no intent to limit the present invention. For example, a configuration may be taken so that the quality requirement content is conveyed by a data format such as XJDF (exchange job definition format).

(47) Note that in the above embodiment, the workflow management server 100 was described with an assumption that it executes a PRX interpretation and print data preflighting; however, limitation is not made to this. For example, in another embodiment, there is a case where it is executed by the order reception system server 110. In this case, the display (S706) of the warning screen and the display (S711) of the confirmation screen are both displayed on the order reception system management terminal 111, thereby enabling detection of the inconsistencies earlier and the quick request of the order receiver to review the quality requirement.

(48) Also, in another embodiment, there is a case where it is executed by the print server 122 of the production system 120. In this case, the display (S706) of the warning screen and the display (S711) of the confirmation screen are both displayed on the production operator terminal 125, thereby enabling monitoring of the print job that has inconsistent quality requirements until just before its execution.

(49) By virtue of the present invention, the inconsistencies between the quality conditions specified for the print job and the corresponding print data can be detected then warned about.
