Abstract
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.
