A rotating rubber ink take-up roller, which is partially immersed in an ink
reservoir, picks up the ink and transfers it onto a steel roll. Both the
rubber roll and the steel roll have a surface without a profile and serve only
for ink dosing. A rubber plate, attached to the plate roller, contains the
printing designs in profile. The plate roller picks up the ink from the ink
coated steel screen roll and transfers it onto the film, which is supported by
the back up roll. The film finally cures in the drying oven.
Multi-color designs can be produced with several successive printing stations
such as the one described below.
