Method for controlling the ink guidance in a printing machine |
摘要 |
A method for controlling the ink guidance of a printing machine, especially a sheet-fed offset printing machine. Ink-density spectra are recorded by means of a spectral photometer at a plurality of image points of the original and of the printed copy and the differential ink-density spectra are determined from these values. These differential ink-density spectra are then represented as a linear combination of the individual ink-density spectra of the inks participating in the composite printing. Regulating commands for the ink-guide members of the printing machine are thereupon derived from the proportionality factors of this linear combination.
