Exposing a Screen vs. Imaging a Screen: Complete emulsion exposure versus obtaining an image on the screen provides two very different results during production. Let’s start at the beginning to see how this difference is often the difference between achieving optimum press performance and struggling to achieve hourly production goals.

Owners will buy brand new screen exposure lamps without considering if the model they choose will expose screens well for all ink systems, then try out every emulsion possible, and yet often suffer through countless screen failures during production. Why? The screen maker simply cuts corners based on past experience that underexposing the emulsion will help develop finer details better.
