Abstract (en)

[origin: EP0941847A1] An ink feed system for an offset printing process has a constant pressure ink reservoir (5) which supplies ink to a dosing slit (8) and onto an ink roller (2). The position of the ink supply head (4) is adjusted by a cam (14) and a servo drive (16,17) to vary the spacing of the ink head from the roller. A spreader blade (9) on the ink head spreads the applied ink into an even controlled thickness layer. The spreader blade ensures that any non uniformity in the ink feed is compensated by the blade
