A digital color box for a printing press and a digital ink supply system and its application method

摘要

The invention relates to a digital ink fountain (4) for a printing machine, comprising a printing ink container (5) for storing the printing ink, an ink main pipe (8) connected to the ink container, at least one ink dosing feeding means (16), printing ink Feed lines (10), a controller (17) and a signal detection device (18), wherein an ink inlet of the ink metering feeder is connected to the ink main and an ink outlet of the ink metering feeder is connected to one end of the ink feed pipe and the other end of the ink supply line discharges the ink, the ink metering supply device being based on the volume or mass as the basis for the metering, and each ink metering feeder being associated with a color zone, the signal detecting device being the start / stop State signals of the printing press and the signals of Druckges speed of the printing press and collects them to the control unit (17), which control unit in each case controls the start / stop operation of the individual ink-Dosierzuführeinrichtungen and the discharge flow rate of the ink. The invention further relates to a digital Farbversorgungssytem for a printing press and its application method. The color-versatility system can be accurately controlled in real time, while being highly automated and digitized, and can realize one-way ink delivery and avoid backflow of the ink.
