Abstract
A picture color tone controlling method for a printing press is disclosed wherein color tone control can be performed using an IRGB densitometer which requires a lower cost than a spectrometer. A target mixed color halftone density for each ink supplying unit width when a printing picture is divided with an ink supplying unit width of an ink supplying apparatus (6, 7) is set. Then, an actual mixed color halftone density for each ink supplying unit width of a regular printing sheet obtained by printing is measured using an IRGB densitometer (1), and the ink supplying amount is adjusted for each ink supplying unit width so that the actual mixed color halftone density may approach the target mixed color halftone density.
