  For example, a print format as shown in FIG. 2 is applied to the tack roll paper TWP in this embodiment. The printing position of the tack roll paper TWP is specified by a sheet SN in which a printable area is divided at a predetermined interval in a direction orthogonal to the conveyance direction, and a position P in the sheet SN. Here, a print target area is set in each position P, and a peelable label LB is formed in each position P. Further, each sheet SN is printed with a start position mark SP of the sheet SN in the vicinity of the head in the transport direction, and a serial number SB is printed in each sheet SN. These sheet SN, start position mark SP, and serial number SB are used for reprint information and position information of a label LB to be described later.

  The control unit 17 described above corresponds to the “reprint instruction unit” in the present invention.

  The image inspection device 5 inspects the image printed on the tack roll paper TWP based on the image data from the photographing unit 19 of the printing device 3 and the printing data from the control unit 17 of the printing device 3. The inspection is performed by the image inspection unit 21, and for example, it is determined whether or not the image is a defective print due to image omission or image smearing. The image inspection apparatus 5 further includes a defective print image reprint notification unit 23 and a defective print image position information notification unit 25.

  If the image inspection unit 21 inspects the image on the tack roll paper TWP as a result of the inspection of the image on the tack roll paper TWP, the defective print reprint notification unit 23 notifies the data processing apparatus 1 of the image. Reprint information indicating that reprinting is necessary is notified. The reprint information includes which sheet of the plurality of sheets on which the image of the tack roll paper TWP is printed and position information on the sheet. The data processing apparatus 1 that has received the reprint information receives print data including image data corresponding to the defective print image based on the sheet and print data used for printing at the position of the sheet. Output to the printing apparatus 3.

  Further, the defective print image position information notification unit 25 outputs position information on the tack roll paper TWP of the image that needs to be reprinted to the printed matter inspection apparatus 7. The position information is position information on the tack roll paper TWP including the defective print image, and includes the sheet on the tack roll paper TWP and the position on the sheet, similarly to the reprint information.

  The data processing apparatus 1 and the printing apparatus 3 described above correspond to the “printing apparatus” in the present invention.

  The printed matter inspection apparatus 7 is generally installed at a location different from the data processing apparatus 1, the printing apparatus 3, and the image inspection apparatus 5 described above. For example, the data processing device 1, the printing device 3, and the image inspection device 5 are installed in a printing company, and the printed material inspection device 7 is installed in a company that performs an operation of attaching a printed material to an article from tack roll paper TWP. There are many. For this reason, the above-described position information is sent to the printed matter inspection apparatus 7 via communication via the Internet (online method) or a storage medium (offline method) such as a USB memory.

  In FIG. 1, among the tack roll paper TWP moved to the printed product inspection apparatus 7, the tack roll paper TWP including the defective print image is represented by reference numeral TWP1, and the tack roll paper TWP including the reprinted image is represented by reference numeral TWP2. ing. In addition, the image by reprinting may be printed on the latter half portion of the tack roll paper TWP including the defective print image, and the tack roll paper TWP may be unified.

  The printed matter inspection apparatus 7 includes a paper feed unit 27, a transport unit 29, a paper discharge unit 31, and a print medium printing defect position detection unit 33. In the paper feeding unit 27, tack roll paper TWP1 including a defective print image is set around the horizontal axis. The transport unit 29 includes a driving roller and a transport roller (not shown), and unwinds the tack roll paper TWP1 of the paper feed unit 27 and sends it to the print medium print defect position detection unit 33 side. The paper discharge unit 31 winds the tack roll paper TWP1 around the horizontal axis from the print medium printing defect position detection unit 33 side. The print medium print defect position detection unit 33 controls the conveyance of the tack roll paper TWP1 based on the position information given from the print defect image position information notification unit 25 of the image inspection apparatus 5. Then, when the position where the defective print image has moved to the re-placing part (not shown), the tack roll paper TWP1 is stopped at that position and, for example, the operator of the printed matter inspection apparatus 7 takes the tack roll paper TWP2. Are urged to replace the reprinted image with the defective print image of the tack roll paper TWP2. As a result, all the images on the tack roll paper TWP1 including the defective print image become the tack roll paper TWPn which is a normal image. This tack roll paper TWPn is used for affixing to a product by a separate affixing device or the like.

  Next, with reference to FIG. 3 and FIG. 4, an operation example in the above-described printing system will be described. FIG. 3 is a flowchart showing a flow of processing from printing processing to inspection processing, FIG. 4 is a schematic diagram showing a printing example, and (a) is a schematic diagram of tack roll paper including a defective print image. (B) is a schematic diagram of the tack roll paper containing the image by reprinting. In the flowchart of FIG. 3, a part surrounded by a broken line is a part particularly related to the operation of the image inspection apparatus 5.

Step S1
Based on the printing data from the data processing apparatus 1, for example, the printing apparatus 3 performs variable printing with different addresses (AD1 to AD8) and names (NM1 to NM8) for each label LB on the tack roll paper TWP. Specific printing is, for example, as shown in FIG.

Step S2
In the image inspection unit 21 of the image inspection apparatus 5, an inspection process on the tack roll paper TWP is performed. Here, for example, it is assumed that there is a defective print image on labels LB whose serial numbers SB are 0001, 0004, 0005, and 0007 (shown as NG in FIG. 4A).

Step S3
Processing branches depending on whether or not there is a defective print image in the image inspection apparatus 5. If there is a defect, the process proceeds to step S4, and if there is no defect, the process proceeds to step S6.

Step S4
Here, since there is a defective print image, the reprint information is notified from the defective print image reprint notification unit 23 of the image inspection apparatus 5 to the data processing apparatus 1.

Step S5 (print defect image information notification process)
Since there is a print failure image, the print inspection device 7 is notified of position information from the print failure image position information notification unit 25 of the image inspection device 5. This notification may be online or offline as described above.

  After the notification, the process returns to step S1 to perform printing processing (reprinting). In this example, the objects of reprinting are images having serial numbers SB of 0001, 0004, 0005, and 0007. Specific reprinting is as shown in FIG. 4B, for example. . Then, the inspection is performed in step S2, and if there is no defect in step S3, the process proceeds as follows. Here, an image including a defective print image is referred to as tack roll paper TWP1, and a reprinted image is referred to as tack roll TWP2.

Step S6
The two tack roll papers TWP 1 and TWP 2 are conveyed to the place of the printed matter inspection apparatus 7.

Step S7 (conveyance process)
The tack roll paper TWP1 is set in the paper feeding unit 27 of the printed product inspection apparatus 7 and is conveyed by the conveyance unit 29 of the printing unit inspection apparatus 7.

Step S8 (Process of detecting defective print image)
If the print medium print defect position detection unit 33 detects the position of the print defect image based on the position information, the conveyance is stopped at that position. Then, for example, the label LB including the image of the poorly printed image is peeled off from the tack roll paper TWP1, and the corresponding label LB is replaced and replaced from the tack roll TWP2 including the reprinted image. Specifically, for example, the label LB with the serial number 0001 is peeled off, and the label LB with the serial number A001 is pasted thereon.

  According to this embodiment, after a predetermined image is printed on the tack roll paper TWP by the printing device 5, the image inspection device 5 inspects the image, and if there is a defective print image, the defective print image reprint notification is issued. The unit 23 notifies the data processing apparatus 1 of the reprint information and causes the printing apparatus 3 to reprint the image corresponding to the defective print image. The defective print image position information notification unit 25 notifies the printed matter inspection apparatus 7. The position information of the defective print image is notified. The printed matter inspection apparatus 7 conveys the tack roll paper TWP, and detects the position of the defective print image on the tack roll paper TWP based on the positional information from the defective print image position information notification unit 25 by the printed matter defective position detection unit 33. To do. Therefore, the printed matter inspection apparatus 7 can replace the reprinted image with the defective print image at the position of the defective print image on the tack roll paper TWP based on the position information. As a result, even if the tack roll paper TWP is variable printing, it can be replaced with normal printing.

  Further, since the reprint information includes the sheet SN and the position P in the sheet SN, the printing apparatus 3 can accurately reprint the image corresponding to the defective print image.

  Further, since the print medium is the tack roll paper TCP, the printed product inspection apparatus 7 can easily replace the label LB of the defective print image and the reprinted label LB corresponding to the defective print image.

  The present invention is not limited to the above embodiment, and can be modified as follows.

  (1) In the above-described embodiment, the printing unit 14 of the printing apparatus 3 is an ink jet type, but the present invention is not limited to such a configuration. For example, other methods such as a laser method can be applied.

  (2) In the above-described embodiment, the tack roll paper TWP is exemplified as the print medium, but the present invention is not limited to this. For example, the print medium may be a sheet instead of roll paper. Further, when the print medium may be a film and is not a peelable label, it can be replaced by cutting out the label of the defective print image and welding the label including the image of normal printing.

  (3) In the above-described embodiment, the sheet SN, the position P, and the serial number SB are used as the reprint information and the position information. However, in the present invention, if the position of the defective print image can be specified, these pieces of information are used. It is not limited to.
