This invention provides a data processing apparatus operable to execute processing requested by an application, where the apparatus comprises a processing unit configured to, if there is an instruction for processing, execute the processing in accordance with a command list indicated by the instruction; and a control unit configured to, upon receiving a request for processing from the application, generate a command list corresponding to the request and instruct the processing unit to perform the processing, wherein the processing unit comprises a switching unit configured to, upon receiving, from the control unit, a second instruction during execution of a command list for a first instruction, switch to execution of a command list for the second instruction at a timing of execution of a command that is a control point preset in the command list for the first instruction.

Limitations of conventional dimensional printing techniques are addressed to provide features and flexibility not presently available, including extracting images selectively from a Postscript® or PDF file and thus enable texturing of individual images within a page; constructing the texture automatically directly from the image using image processing techniques; visualizing the texture to be applied to an image via construction of a bump map or normal map in openGL and DirectX®; adjusting texturing parameters via visual feedback in openGL and DirectX®; and inserting a clear texture back into a PDF file for printing automatically.

A method includes generating color correspondence information correlating L number of first reference color specification values in a first color space with L number of determined second color specification values in a second color space on a one-to-one basis. The L number of determined second color specification values includes (L−Q) number of unmodified second reference color specification values, (Q−N) number of modified second reference color specification values modified in a first modification process but not in the second modification process, and N number of remodified second reference color specification values which are modified in both the first modification process and the second modification process, where L is an integer greater than or equal to two, Q is an integer greater than or equal to one and smaller than or equal to L, and N is an integer greater than or equal to one and smaller than or equal to Q.

A method is disclosed including a print controller receiving print job data defined according to a first language, receiving a job ticket defined according to a second language, processing the print job data according to the second language and implementing counters defined according to the first language to track progress while processing the print job data.

There is provided with an information processing apparatus. Print data of a plurality of pages are acquired. Quality requirement data including information indicating a quality requirement for a print product are generated based on the print data in a data-by-data basis or in a page-by-page basis, and information for specifying whether the quality requirement is defined in the data-by-data basis or defined in the page-by-page basis is generated. The print data and the quality requirement data are transmitted to a printing service for a print request.

A print system includes a print job generating device including a print job generating section configured to generate a print job including ink color information indicating ink colors to be used in printing and raster image data for each of the ink colors, and a transmission section configured to transmit the generated print job to an image forming device, and an image forming device including a reception section configured to receive a print job transmitted from the transmission section, a processing section configured to determine ink colors to be used in printing and ink colors not to be used in printing based on the ink color information included in the print job, and a display controller configured to display preview images indicated by the raster image data of the ink colors to be used in printing in a display section based on a result of the determination.

A non-transitory computer-readable recording medium stores a printing program for executing on a computer. The printing program causes the computer to function as an available capacity determining circuit and a print data transmitting circuit. The available capacity determining circuit determines an available capacity available for a print job in a storage device of the image forming apparatus. The print data transmitting circuit transmits print data to the image forming apparatus, the print data being adapted to the available capacity determined by the available capacity determining circuit. The print data transmitting circuit converts the variable print data into print data without the reuse data and transmits the converted print data to the image forming apparatus in a specific case where the available capacity is less than the variable printing capacity.

A method of enhancing quality of an image object included in a compound document, and an apparatus for performing the method are provided. The method includes receiving a request to print a compound document including an image object, merging parts corresponding to the image object from among data corresponding to the compound document and enhancing the quality of the image object, and encoding data corresponding to the compound document by using a printer control language (PCL) and outputting the encoded data.

The image forming apparatus includes a color conversion processing unit that has an input profile for color conversion to first image data which is image data of a device-independent color space, and an adjustment target profile for color conversion to second image data which represents gradation values of the plurality of color materials, and a simulation profile for color-converting the second image data to third image data of the device-independent color space, a profile adjustment unit that adjusts the adjustment target profile in accordance with the user input, determines whether or not a color difference before and after the adjustment of the adjustment target profile is smaller than a preset threshold value, and updates the adjustment target profile by using the adjustment target profile after the adjustment when the profile adjustment unit determines that the color difference is smaller than the threshold value, and a color difference calculation unit.

In some examples, classification based printing material set selection may include analyzing a preliminary rendering. Classification based printing material set selection may further include generating raster data based at least in part on a further rendering of the print data, and generating further print data including the raster data.
