Abstract:

This document aims to explore effects of exposure time variation on flexographic plates. The photopolymer flexographic plates are exposed using ultra violet light from back side and face (printing) side. The Face and back exposure time have effect on relief depth formation. The relief depth is the difference between the plate surface and the supporting floor—the measured physical difference between image and non-image area on a relief plate and change in relief depth has direct effect on quality of printing. The conclusions would be helpful in understanding the significance of proper exposure times under standard .
