FEEDBACK

In Lithographic printing, Feedback refers to ink feeding-back into the dampening sytem. Ink can buildup on the water metering rollers, or can buildup in the chill tanks. Feedback is more common in systems with “reverse-nip” water metering rollers. Properly set rollers, and carefully selected fountain solution, are essential to preventing Feedback. Graphic Ink has fountain solutions designed for reverse-nip systems.
