Abstract

The present disclosure provides an inspection system for inspecting printed products and a control method of the inspection system. An inspection system includes a storage unit configured to store set area information, the area information being set before receiving a single instruction for transmitting data including an image to be inspected based on the set area information. Data sent in response to the single instruction is received via the interface. The controller generates reference data based on the received data and causes the printing unit to print the image, and checks a read image generated by reading the printed image based on the generated reference data and the stored area information.

Description

Inspection system for inspecting printed matter and control method of inspection system Technical Field The present disclosure relates to an inspection system that inspects printed products and a control method that controls the inspection system. Background Quality inspection is sometimes performed on a print obtained by printing using a printer. In this case, the inspection apparatus compares a read image formed by reading the print product using a scanner or the like with a reference image, and performs quality inspection on the print product based on the comparison result. As the reference image, for example, a RIP image generated before printing by a printer, a RIP image generated by RIP software, or the like is used. For example, in the case where the print has a stain, a portion corresponding to the stain is reflected on a read image of the print. Then, in the quality inspection, the read image containing the portion corresponding to the stain is compared with the RIP image not containing the portion corresponding to the stain, so that the inspection result of the print is not good. Furthermore, before quality inspection is performed, it is necessary to register a reference image in the inspection apparatus. For example, japanese patent application laid-open (japanese unexamined patent publication) No. 2024-006762 discloses an apparatus that performs a reference image registration job for registering a reference image before quality inspection. The apparatus described in japanese patent application laid-open (japanese unexamined patent publication) No. 2024-006762 registers reference images of all pages included in a print job. However, in the case of using the apparatus described in japanese patent application laid-open (japanese unexamined patent publication) No. 2024-006762, it is necessary to perform two job inputs, i.e., a job for reference image registration and a job for quality inspection. Then, RIP processing of the job for reference image registration (hereinafter referred to as "pre-RIP processing") and RIP processing of the job for quality inspection (hereinafter referred to as "post-RIP processing") are sequentially performed. For a user who needs quality inspection, there is a problem in that the time of the pre-RIP process feels like the waiting time before the start of the post-RIP process. The waiting time is preferably short.
