KR-20260067338-A - INSPECTION SYSTEM CAPABLE OF QUICKLY PERFORMING INSPECTION OF PRINT PRODUCT

Abstract

The inspection system includes a display unit and an interface configured to receive data comprising multiple pages. The data is transmitted from the computer in response to a single command for transmitting data by a computer user. Based on the received data, reference data is generated, and a printing unit prints multiple pages onto individual sheets of paper. Each of the printed multiple pages is read to generate a read image of each page. Based on the generated reference data, the read image of each page is inspected. An inspection result indicating whether the read image of a page is defective is displayed on the display unit during the inspection of the read image of one of the subsequent pages in the multiple pages.

Description

Inspection system capable of quickly performing inspection of printed products The present disclosure relates to an inspection system capable of rapidly performing inspection of printed materials. An image forming device generates printed materials by printing an image onto paper based on image data. In particular, image forming devices used for commercial printing sometimes print a large number of copies or pages. Additionally, the quality of the printed materials may be inspected. In this case, a reading image obtained by reading the printed material using, for example, a scanner in an inspection device is compared with a reference image, and the quality of the printed material is inspected based on the comparison result. Furthermore, the reference image needs to be registered in the inspection device to perform quality inspection. For example, Japanese Patent Publication No. 2023-80455 describes a device that generates a reference image registration operation for registering a reference image. However, when using the device described in Japanese Patent Publication (Published) No. 2023-80455, not only is the creation of a reference image registration task required, but an additional task to form an image to be inspected is also required. Since the two tasks are created independently as described above, this causes a problem in that the inspection time of the printed material is extended by the time required to create these tasks. In particular, when a large number of copies or a large number of pages are printed, the inspection time of the printed material tends to be significantly extended.
