  • Publication number: 20210271942
    Abstract: To reduce a feedback delay as much as possible while maintaining the suppression effect of the tone variation in a case where tone correction is performed real time during processing of a print job. The density reference value for tone correction is managed in association with the sheet type registered for the feeding cassette of the printing apparatus. Due to this, even in a case where print jobs are switched, the feedback of a parameter necessary for tone correction is not interrupted unless the sheet type registered for the feeding cassette is changed.
