An image forming system includes an image forming unit, an inspection unit, a conveyance unit configured to convey a sheet to the inspection unit, a controller configured to execute a first inspection mode in which a sheet having an image formed thereon is conveyed by the conveyance unit to the inspection unit and is inspected, and a second inspection mode in which, without executing image forming by the image forming unit, a sheet is conveyed by the conveyance unit to the inspection unit and is inspected, and a setting unit configured to set a recovery process. The setting unit permits the setting of the recovery process in the first inspection mode and prohibits the setting of the recovery process in the second inspection mode.

An image forming apparatus includes one or more processors and one or more memories storing program instructions, which, when being executed by the one or more processors, causes the one or more processors to generate a print image to be printed on a sheet of paper and a position correcting mark for front and back side registration having a brightness lower than a minimum brightness of the print image; control printing of the print image and the position correcting mark on a first side of the sheet of paper; control reading the print image and the position correcting mark from the first side and control generating of read image data; and detect, from the read image data, the position correcting mark on the first side using a brightness difference.

A can body printing system includes: a host device 10; and a printing device 30 configured to print an image acquired from the host device 10 onto can bodies. The print image information acquisition section 301 of the printing device 30 acquires, from the host device 10, image information to which an authorization for printing on can bodies is added. The activation control section 305 of the printing device 30 prints an image based on the image information onto can bodies on the basis of the authorization for printing on can bodies added to the acquired image information.

An information processing apparatus includes a processor configured to: receive a print instruction to print an image rasterized by another information processing apparatus; associate the print instruction with any one of plural ejection destinations to which a recording medium printed in response to the print instruction is ejected; and, in a case where the ejection destination associated with the print instruction waits for ejection of a recording medium subsequent to the already ejected recording medium, execute a print instruction for the subsequent recording medium, and not execute a print instruction for ejecting a recording medium other than the subsequent recording medium to the ejection destination.

An image forming apparatus according to the present disclosure includes: a hardware processor configured to control an image former on a basis of a job pertaining to a printing execution command. The hardware processor is configured to divide the job pertaining to the printing execution command into a plurality of shortjobs, and configured to stop conveyance of the roll sheet and forcibly eject degraded toner from a developing device of the image former at a pause timing between short jobs temporally adjacent to each other among the plurality of short jobs; and the hardware processor sets a job content of each of the plurality of short jobs such that an image of a printing target is inverted upside down for each job switching of the plurality of short jobs.

There is provided a method for notifying an operator of necessity of implementation of an inspection to be manually performed by the operator. A method for controlling a job processing system that causes a job processing apparatus to execute a job, the method includes receiving required quality data, and notifying, based on the required quality data received in the receiving, a user that an output product output by executing the job needs to be inspected by an inspection apparatus.

A RIP simulation device that enables a rapid grasp of a part having a problem in RIP speed and a specific detail of the problem is achieved. While the RIP prediction screen is displayed on a display unit, the result display control unit causes the display unit to display a sheet number corresponding to a position that is on a line graph representing a predicted RIP time for each sheet and is being designated by an input operation unit. When a sheet number displayed on the display unit is selected by the input operation unit, the result display control unit causes the display unit to display an analysis result screen indicating an analysis result related to the page corresponding to the sheet number on the basis of the correspondence relationship between sheets and pages when print output is actually executed.

A job management apparatus includes a processor configured to: attach an order identifier, linked to a production order, to a job that has been created in response to the production order of a printed material; transmit the job and the order identifier attached to the job to one of printing systems to perform the job; when one of the order identifiers is specified and a reproduction order of the printed material corresponding to the specified order identifier is received, make an inquiry to the printing systems as to whether the printing systems have the job with the specified order identifier attached; and in response to a reply from each of the printing systems responding to the inquiry, detect a printing system storing the job corresponding to the reproduction order.

Digital watermarking is adapted for the variable data printing. A reference signal serves as a proxy for optimizing the embedding a watermark in a host image to be printed. Using the reference signal, embedding parameters are generated, which are a function of constraints such as visual quality and robustness of the machine readable data. Adjustments needed to embed a unique payload in each printed piece are generated using the embedding parameters. These adjustments are stored in a manner that enables them to be efficiently obtained and applied within the RIP or press during operation of the press. Various other methods, system configurations and applications are also detailed.

A printing apparatus connectable to an inspection apparatus in a communicable manner according to the present invention includes a reception unit configured to receive an inspection job including at least information indicating whether a correct answer image is to be registered, an analysis unit configured to analyze the received inspection job, and, a control unit configured to perform control so that the correct answer image is transmitted to the inspection apparatus in a case where the correct answer image is to be registered, and to perform control so that an instruction to select the correct answer image is transmitted to the inspection apparatus in a case where the correct answer image is not to be registered, as a result of the analysis.
