A printing system includes a printing apparatus that prints an image on a sheet, a sheet processer that executes sheet processing, and a sheet detection sensor that detects a sheet on which the sheet processing is performed not in association with the printing of an image, where the printing of an image is restricted in response to detection of a sheet by the sheet detection sensor.

Printing system, printing system control method, and storage medium

A printing apparatus includes an image forming portion which forms a chart image on a sheet conveyed from a sheet feeding deck, a color measure portion which performs color measurement by reading the chart image formed by the image forming portion, and one or more controllers including one or more processors and one or more memories. The one or more controllers are configured to generate correction data based on color measurement results by the color measurer portion and a reference value, and perform correction for target image data by using the generated correction data. The reference value is obtained by performing color measurement by the color measure portion and is registered in association with a type of sheet on which the chart image is formed, and in a case where the type of sheet on which the chart image is formed is changed, the reference value is updated.

Printing apparatus, printing control method, and storage medium

A printing system is provided that does not produce a wasteful defective product by suppressing inconsistency in collated pages between a reference image and an inspection image. In a case where a read image obtained by reading an image on a sheet for which print processing has been performed based on a print job is a blank sheet image but a reference image registered in association with the print job is not a blank sheet image, a page of a reference image and a page of the read image are matched with each other by using a blank sheet image registered as a reference image not in association with the print job.
