  • Process for influencing the optical density of a printing ink layer on a print carrier
    Patent number: 5568769
    Abstract: A process for affecting the ink value or colorimetric density of a printing ink layer on a substrate compares a production value in a microprocessor with a set value previously supplied to the microprocessor. Deviations of the production ink values or colorimetric values from the set values which exceed a pre-selected threshold will generate a signal that will change the rotational speed of a moistening device to reduce the difference between the production value and the set value.
