Epson Stylus Pro 7900 Computer to Plate

Selected FAQ

Q:
What if I see lines on the press sheet in the direction of the plate as it travels through the PCU?
A:
Lines spaced approximately 2 inches apart on the plate may appear if the plate is fed into the PCU before the Epson ink is dry. The lines are caused by the input drive rollers on the PCU. The most common cause of this is over-inking a RIP setting, that reduces the amount of ink being applied to the plate surface. The lines are most noticeable near solid areas. The remedy is to adjust the RIP ink reduction settings, to allow more drying time before inserting the plate in the PCU, or to reduce the ambient relative humidity. This over-inking situation will also reduce the run length on the plates.
