[0005] [Patent Document 1] Japanese Patent Application Publication No. 2022-137718 [Patent Document 2] Japanese Patent Publication No. 2022-146528 [Patent Document 3] Patent Publication No. 2021-165202 Summary of the Invention [Problem to be solved by the invention]

[0006] In a printing system, multiple types of inspections are sequentially performed on the printed material of each page included in a print job, and the operation of the printing system when an abnormality is detected can be preset for each type of inspection. However, when two or more types of abnormalities are detected on a single page, the printing system is configured to prioritize the operation corresponding to the abnormality that is detected first among the two or more types of abnormalities detected.

[0007] For this reason, when two or more types of abnormalities are detected on a single page, even if, for example, performing an operation corresponding to the later-detected abnormality makes it unnecessary to perform an operation corresponding to the earlier-detected abnormality, the operation corresponding to the earlier-detected abnormality is performed first, which can result in a decrease in the number of pages printed per hour by the printing system.

[0008] The present disclosure has been made in consideration of the above facts, and aims to provide a printing system and program that can prevent a decrease in the number of pages printed per hour by the printing system when two or more types of abnormalities are detected on a single page, compared to when priority is given to performing the operation corresponding to the abnormality that is detected first. [Means for solving the problem]

[0009] A printing system according to a first aspect includes a processor that waits until multiple types of inspections are completed by an inspection unit on a single page of printed material printed by a printing unit, and cancels the execution of a print job including the page if two or more types of abnormalities are detected on the single page and the actions preset for each of the two or more types of abnormalities detected include a cancel termination to cancel the execution of the print job.

[0010] In a second aspect of the printing system, in the printing system of the first aspect, the processor notifies the detection of an abnormality and waits for user operation when two or more types of abnormalities are detected on the one page, and the cancellation termination is not included in the actions preset for each of the two or more types of abnormalities detected, and user intervention to wait for user operation is included in the actions preset for each of the two or more types of abnormalities detected.

[0011] In a printing system according to a third aspect, in the printing system according to the first aspect, the processor cancels the execution of a print job including the page when two or more types of abnormalities are detected on the page, and the two or more detected abnormalities include misreading of at least one of a first mark for gradation correction and a second mark for registration adjustment printed on the page, and the preset action for the abnormality in which the misreading occurred is to cancel and terminate.

[0012] A printing system according to a fourth aspect is the printing system according to the third aspect, wherein the processor notifies the user of the detection of an abnormality and waits for a user operation when two or more types of abnormalities are detected on the one page, and the two or more detected abnormalities include misreading of at least one of a first mark for gradation correction and a second mark for registration adjustment printed on the one page, and the preset action for the abnormality in which the misreading occurred is other than the cancellation termination.

[0013] A program according to a fifth aspect causes a computer to wait until multiple types of inspections are completed by the inspection unit on a single page of printed material printed by the printing unit, and if two or more types of abnormalities are detected on the single page and the actions preset for each of the two or more types of abnormalities detected include a cancel termination to cancel the execution of the print job, the program causes the computer to execute a step of canceling the execution of the print job including the page. [Effects of the Invention]

[0014] According to the first and fifth aspects, when two or more types of abnormalities are detected on a single page, priority is given to executing the cancel termination operation among the operations corresponding to the detected abnormalities, thereby preventing a decrease in the number of pages printed per hour by the printing system compared to when priority is given to executing the operation corresponding to the abnormality detected first.

[0015] According to the second aspect, when two or more types of abnormalities are detected on one page and a cancel termination is not included in the actions preset for each of the two or more types of abnormalities detected, it is possible to prevent unnecessary printing.

[0016] According to the third and fourth aspects, when at least one of the first mark for gradation correction and the second mark for registration adjustment is misread, it is possible to prevent unnecessary printing in which at least one of the gradation and registration cannot be guaranteed.

DETAILED DESCRIPTION OF THE INVENTION

[0018] An example of an embodiment of the present disclosure will be described in detail below with reference to the drawings. Fig. 1 shows a schematic configuration diagram of a printing system 10 according to this embodiment. The printing system 10 includes a printing device 12 and a print server 30. The printing device 12 includes a paper feed unit 14, a printing unit 16, an inspection unit 18, and a paper discharge unit 20.

[0019] A stack of multiple sheets of paper is set inside the paper feed unit 14. The sheets stacked in the paper feed unit 14 are taken out one by one, starting from the top sheet, by a paper take-out section (not shown), and fed into the printing unit 16 in order.

[0020] The printing unit 16 prints images on paper sheets fed from the paper feed unit 14, for example, by electrophotography or inkjet printing. The printing unit 16 receives image data to be printed on each page of paper sheets as bitmap print data (also called RIP (Raster Image Processor) data) from the print server 30 (see also (2) in FIG. 2). The printing unit 16 also reads the images printed on the paper sheets using a scanner (not shown) and sends the read results (scanned image data) together with the print data (RIP data) to the inspection unit 18 (see also (3) in FIG. 2). The printing unit 16 is an example of a printing section in the present disclosure.

[0021] As shown in Fig. 2, the inspection unit 18 includes an image inspection unit 22, a reading inspection unit 24, a density inspection unit 26, and a registration inspection unit 28, and each of the inspection units 22 to 28 is capable of performing four different types of inspection. That is, as also shown in Fig. 3(A), the image inspection unit 22 performs image inspection to check for abnormalities in the printed image by comparing the scanned image data received from the printing unit 16 with the print data (RIP data). The inspection unit 18 includes a CPU, ROM, RAM, storage, etc. (not shown), and the CPU loads programs to realize the functional components of the image inspection unit 22, reading inspection unit 24, density inspection unit 26, and registration inspection unit 28.

[0022] In this embodiment, the printing unit 16 receives verification data (for example, data 50 in CSV format shown in FIG. 3A) representing a different barcode for each page to be printed on each page of paper from the print server 30 along with the print data, and prints the barcode represented by the received verification data on each page of paper (see also barcode 52 shown in FIG. 3A). As also shown in FIG. 3A, the reading inspection unit 24 reads barcode 52 from the scanned image data and compares the read barcode with the verification data to perform a reading inspection to check for abnormalities such as missing pages.

[0023] In this embodiment, the printing unit 16 prints gradation correction patches 54 for each of the CMYK colors on the edge of each page of paper, as shown in Fig. 3(B). The density inspection unit 26 recognizes the density (gradation) of the gradation correction patches 54 from the scanned image data, and performs a density inspection to check for abnormalities such as deviations in density (gradation) of the printed image. The gradation correction patches 54 are an example of a first mark for gradation correction in this disclosure.

[0024] In this embodiment, the printing unit 16 also prints registration marks 56 shown in Fig. 3(B) at predetermined positions on the edge of the paper. The registration inspection unit 28 performs a registration inspection to check for abnormalities such as misalignment of the registration position by recognizing the positions on the paper where the registration marks 56 are printed from the scanned image data. The registration marks 56 are an example of second marks for registration adjustment in this disclosure.

[0025] The inspection unit 18 is arranged such that the inspection units 22 to 28 perform various inspections in a fixed order on each page of paper on which an image has been printed by the printing unit 16. In this embodiment, it is possible to set in advance for each type of inspection whether or not to perform an inspection (described later). The inspection unit 18 performs the inspections that have been set to be performed in advance on each page of paper, and transmits the results of the inspections to the printing unit 16 on a page-by-page basis. The printing unit 16 then transfers the inspection results received from the inspection unit 18 to the print server 30 (see also (4) in FIG. 2).

[0026] The inspection unit 18 is also provided with a purge tray 18A (see FIG. 1). In this embodiment, whether or not a page (paper sheet) on which an abnormality has occurred as a result of the inspection can be set in advance for each type of inspection (described later). When an abnormality occurs for which ejection to the purge tray 18A is set, the inspection unit 18 ejects the page (paper sheet) on which the abnormality has occurred to the purge tray 18A. The inspection unit 18 is an example of an inspection section in the present disclosure.

[0027] The paper discharge unit 20 is provided with a paper discharge tray 20A (see Figure 1), and paper on which an image has been printed by the printing unit 16 and which has not been discharged to the purge tray 18A by the inspection unit 18 is discharged to the paper discharge tray 20A of the paper discharge unit 20 and stacked.

[0028] On the other hand, the print server 30 includes a CPU (Central Processing Unit) 32, a memory 34 such as a ROM (Read Only Memory) or a RAM (Random Access Memory), a non-volatile storage unit 36 ​​such as a HDD (Hard Disk Drive) or an SSD (Solid State Drive), a communication I / F (Interface) unit 38, and an input / output I / F unit 40, which are communicably connected to each other via a bus. Also, a display unit 42 such as a display and an input unit 44 such as a keyboard are each connected to the input / output I / F unit 40.

[0029] A print control program is stored in the storage unit 36 ​​of the print server 30. The print control program is read from the storage unit 36 ​​and loaded into the memory 34, and the print control program loaded into the memory 34 is executed by the CPU 32, whereby the print server 30 functions as the print control unit 46 shown in Fig. 2. The CPU 32 is an example of a processor in the present disclosure.

[0030] The print control unit 46 waits until the inspection unit 18 has completed multiple types of inspections on one page of the printed material printed by the printing unit 16, and if two or more types of abnormalities are detected on the one page and the operations preset for each of the two or more types of abnormalities detected include a cancel end for canceling the execution of the print job, the print control unit 46 cancels the execution of the print job including that page. The user I / F unit 48 shown in FIG. 2 is composed of the display unit 42 and the input unit 44.

[0031] When information for calling up settings related to inspection by the inspection unit 18 is input via the input unit 44 of the user I / F unit 48, the print control unit 46 causes the display unit 42 of the user I / F unit 48 to display a setting screen 60 such as that shown in Fig. 4, for example. Note that Fig. 4 shows the setting screen 60 related to density inspection by the density inspection unit 26 and register inspection by the register inspection unit 28, but similar setting screens are also prepared for image inspection by the image inspection unit 22 and reading inspection by the reading inspection unit 24.

[0032] The setting screen 60 is provided with a first check box 62 for setting whether or not to perform a corresponding type of inspection, and in this embodiment, when the first check box 62 is checked by the user, the corresponding inspection is performed by the inspection unit 18. The setting screen 60 also has a second check box 64 for setting whether or not, when an abnormality is detected in the corresponding type of inspection, the paper on which the abnormality occurred is discharged to the purge tray 18A of the inspection unit 18. In this embodiment, when the second check box 64 is checked by the user, the paper on which the abnormality was detected in the corresponding inspection is discharged to the purge tray 18A of the inspection unit 18.

[0033] The settings screen 60 also has a radio button 66 for exclusively setting whether to reprint (automatic recovery), to interrupt the print job after reprinting a specified number of times, or to immediately interrupt the print job when the second checkbox 64 is checked.The settings screen also has a radio button 68 for exclusively setting whether to end the print job with an error (cancel and end) or to wait for user action (user intervention) when the print job is interrupted.The user's setting of the radio buttons 66 and 68 exclusively sets "automatic recovery," "cancel and end (without automatic recovery)," or "user intervention (without automatic recovery)" as the action to be taken when an abnormality occurs.

[0034] When the user inputs settings related to the inspection via the setting screen 60, the input settings are input from the user I / F unit 48 to the print control unit 46 (see also (1) in Figure 2), and then transferred from the print control unit 46 to the inspection unit 18 via the printing unit 16 (see also (2) and (3) in Figure 2).

[0035] Next, as an operation of this embodiment, the print control process executed by the print control unit 46 when an image is printed on paper by the printing device 12 will be described with reference to Fig. 5. Note that this print control process is executed for each page of the print job being executed by the printing device 12 as the page to be processed.

[0036] In step 100 of the print control process, the print control unit 46 determines whether all inspections set to be performed for one page (sheet) to be processed have been completed by the inspection unit 18. If the determination in step 100 is negative (step 100: N), step 100 is repeated until the determination is affirmative.

[0037] If the determination in step 100 is affirmative (step 100: Y), the process proceeds to step 102, where the print control unit 46 determines whether or not an abnormality has occurred on the page being processed as a result of inspection by the inspection unit 18. If the determination in step 102 is negative (step 102: N), the process proceeds to step 110, where, as a normal operation, for example, the inspection unit 18 is caused to discharge the page being processed from the inspection unit 18 to the paper discharge unit 20, and the print control process is completed.

[0038] Furthermore, if the determination in step 102 is affirmative (step 102: Y), the process proceeds to step 104. In step 104, the print control unit 46 determines whether multiple types of abnormalities have occurred on one page to be processed. If the number of abnormalities that have occurred on one page to be processed is "1," the determination in step 104 is negative (step 104: N), and the process proceeds to step 110. In this case, as a normal operation, the inspection unit 18 executes an operation corresponding to the one abnormality that has occurred (for example, if a purge is set to be performed when an abnormality occurs, "automatic recovery," "cancel end," or "user intervention"), and the print control process ends.

[0039] On the other hand, if multiple types of abnormalities occur on one page being processed, the determination in step 104 is affirmative (step 104: Y), and the process proceeds to step 106. In step 106, the print control unit 46 determines whether at least one of a density test and a registration test is included in the tests set to be executed, and whether a misreading occurred in which at least one of the gradation correction patch 54 and the registration mark 56 could not be detected in at least one of the executed density test and registration test.

[0040] If the determination in step 106 is negative (step 106: N), the process proceeds to step 108, where the print control unit 46 determines whether or not the multiple types of tests in which an abnormality occurred on the page being processed include a test that is set to purge paper when an abnormality occurs. If the determination in step 108 is negative (step 108: N), that is, if none of the multiple types of tests in which an abnormality occurred on the page being processed are set to purge paper when an abnormality occurs, the process proceeds to step 106. In this case, the inspection unit 18 performs the normal operation of ejecting the page being processed from the inspection unit 18 to the paper ejection unit 20.

[0041] Furthermore, if the determination in step 108 is positive (step 108: Y), that is, if the multiple types of tests in which an abnormality occurred on the page being processed include a test that is set to perform purging when an abnormality occurs, the process proceeds to step 112. In step 112, the print control unit 46 selects an action to be taken when an abnormality occurs from among the multiple types of tests in which an abnormality occurred on the page being processed, in accordance with a predetermined priority order, and executes the selected action.

[0042] That is, in this embodiment, the order of priority for actions to be taken when an abnormality occurs is (1) cancel and end, (2) user intervention, and (3) automatic recovery. Therefore, if "cancel and end" is included among the actions to be taken when an abnormality occurs corresponding to each of the multiple types of tests in which an abnormality occurred on the page being processed, "cancel and end" is selected and executed.

[0043] For example, consider the first case shown in Figure 6(A), where "register misalignment (abnormality in register inspection)" and "image abnormality (abnormality in image inspection)" occur on the page to be processed, and "user intervention" is set as the action to be taken when an abnormality occurs for register inspection, and "cancel end" is set as the action to be taken when an abnormality occurs for image inspection. This first case corresponds to the case in the second row of the table shown in Figure 6(B), and "cancel end" is selected and executed as the action to be taken, which has a higher priority.

[0044] More specifically, in the first case, the page on which the inspection unit 18 detected "misregistration" and "image abnormality" was the sixth page of the first print job, as shown in FIG. 7(A), and the printing unit 16 had printed up to the ninth page of the first print job at that point. Then, by selecting and executing "Cancel End," printing of pages ten and beyond of the first print job is canceled, and pages six through ninth of the first print job are ejected to the purge tray 18A, as shown in FIG. 7(B). Then, as shown in FIG. 7(C), a second print job following the first print job is executed.

[0045] Also, consider the second case where a first and second abnormality occur on the page being processed, and "Automatic Recovery" is set as the action to be taken when an abnormality occurs for the test where the first abnormality occurred, and "Cancel and End" is set as the action to be taken when an abnormality occurs for the test where the second abnormality occurred. This second case corresponds to the case in the third row in the table shown in Figure 6(B), and "Cancel and End" is selected and executed as the action to be taken, as it has a higher priority.

[0046] In this way, if "cancel and end" is included among the actions to be taken when an abnormality occurs corresponding to each of the multiple types of tests in which an abnormality has occurred, selecting and executing "cancel and end" can prevent a decrease in the number of pages printed per hour in the printing device 12.

[0047] In addition, if the actions to be taken when an abnormality occurs corresponding to each of the multiple types of inspections in which an abnormality has occurred on the page being processed do not include "Cancel End" and include "User Intervention," then "User Intervention" is selected and executed as the action to be taken when an abnormality occurs.

[0048] For example, consider a third case in which a first abnormality and a second abnormality occur on a page to be processed, and "automatic recovery" is set as the action to be taken when an abnormality occurs for the test in which the first abnormality occurred, and "user intervention" is set as the action to be taken when an abnormality occurs for the test in which the second abnormality occurred. This third case corresponds to the case in the first row of the table shown in FIG. 6(B), and "user intervention," which has a higher priority, is selected and executed as the action to be performed, notifying the user of the occurrence of the abnormality via the user I / F unit 48 and waiting for user operation. This makes it possible to prevent unnecessary printing.

[0049] On the other hand, if at least one of the gradation correction patch 54 and the registration marks 56 is misread, the determination in step 106 is affirmative (step 106: Y), and the process proceeds to step 114. In step 114, the print control unit 46 determines whether the action to be taken in the event of an abnormality set for the test in which at least one of the gradation correction patch 54 and the registration marks 56 was misread is "cancel end." If the determination in step 114 is affirmative (step 114: Y), the process proceeds to step 116, and in step 116, the print control unit 46 executes "cancel end" as the action to be taken in the event of an abnormality.

[0050] Furthermore, if the determination in step 114 is negative (step 114: N), the process proceeds to step 118, where the print control unit 46 executes "user intervention" as the action to be taken when an abnormality occurs. As a result, as shown in FIG. 8, if a misreading of at least one of the gradation correction patches 54 and the registration adjustment register marks 56 occurs and "automatic recovery" is set as the action to be taken when an abnormality occurs for the test in which the misreading occurred, the action to be taken when an abnormality occurs is changed from "automatic recovery" to "user intervention." This makes it possible to prevent unnecessary printing in which at least one of the gradation and registration cannot be guaranteed.

[0051] As described above, in this embodiment, the print control unit 46 waits until the inspection unit 18 has completed multiple types of inspections on one page of printed material printed by the printing unit 16, and cancels the execution of the print job that includes the page if two or more types of abnormalities are detected on the page and the actions preset for each of the two or more detected abnormalities include a "cancel end" to cancel the execution of the print job. This makes it possible to prevent a decrease in the number of pages printed per hour by the printing system 10 when two or more types of abnormalities are detected on a page, compared to when priority is given to executing the action corresponding to the abnormality that was detected first.

[0052] Furthermore, in this embodiment, if two or more types of abnormalities are detected on a single page, and the actions preset for each of the two or more detected abnormalities do not include "cancel and end," and the actions preset for each of the two or more detected abnormalities include "user intervention" for waiting for a user action, the print control unit 46 notifies the user of the abnormality detection and waits for a user action. This makes it possible to prevent unnecessary printing when two or more types of abnormalities are detected on a single page and the actions preset for each of the two or more detected abnormalities do not include "cancel and end."

[0053] Furthermore, in this embodiment, if two or more types of abnormalities are detected on a page, and the detected two or more types of abnormalities include misreading of at least one of the gradation correction patches 54 and the registration adjustment marks 56 printed on the page, and the preset action for the misreading abnormality is "cancel end," the print control unit 46 cancels the execution of the print job including the page. This makes it possible to prevent unnecessary printing that does not guarantee at least one of the gradation and registration when misreading of at least one of the gradation correction patches 54 and the registration adjustment marks 56 occurs.

[0054] Furthermore, in this embodiment, if two or more types of abnormalities are detected on a page, and the detected two or more types of abnormalities include misreading of at least one of the gradation correction patches 54 and the registration adjustment register marks 56 printed on the page, and the preset action for the misreading abnormality is other than "cancel end," the print control unit 46 notifies the user of the detection of the abnormality and waits for an operation by the user. This makes it possible to prevent unnecessary printing in which at least one of the gradation and registration cannot be guaranteed when misreading of at least one of the gradation correction patches 54 and the registration adjustment register marks 56 occurs.

[0055] In the above embodiment, the printing control process shown in FIG. 5 is described as being executed by the print server 30 (print control unit 46), but the present disclosure is not limited to this, and the above printing control process can also be executed by the inspection unit 18 or the printing unit 16.

[0056] Furthermore, although the above describes a configuration in which a printing control program, which is an example of a program according to the present disclosure, is pre-stored (installed) in the memory unit 36, the program according to the present disclosure can also be provided in a form in which it is recorded on a non-temporary recording medium such as an HDD, SSD, or DVD.

[0057] The above processing can also be realized by a dedicated hardware circuit, in which case it may be executed by a single piece of hardware or by multiple pieces of hardware.

[0058] In each of the above embodiments, the term "processor" refers to a processor in a broad sense, and includes general-purpose processors (e.g., CPU: Central Processing Unit, etc.) and dedicated processors (e.g., GPU: Graphics Processing Unit, ASIC: Application Specific Integrated Circuit, FPGA: Field Programmable Gate Array, programmable logic device, etc.).

[0059] Furthermore, the operations of the processor in each of the above embodiments may not only be performed by a single processor, but may also be performed by multiple processors located in physically separate locations working together. Alternatively, the operations performed by specific multiple processors in each of the above embodiments may be partially or completely integrated into a single processor. Furthermore, the order of the operations of the processor is not limited to the order described in each of the above embodiments, and may be changed as appropriate.

[0060] The program that operates the printing system 10 may be provided by a computer-readable recording medium such as a USB (Universal Serial Bus) memory, a flexible disk, or a CD-ROM (Compact Disc Read Only Memory), or may be provided online via a network such as the Internet. In this case, the program recorded on the computer-readable recording medium is typically transferred and stored in memory or storage. The program may also be provided as standalone application software, or may be incorporated into the software of each device of the printing system 10 as a function thereof.
