DURAPRO polymer clichés from DECO TECH are precision made using UV sensitive photo-polymer emulsion laminated to a thin steel backing plate.

This special photo-polymer emulsion makes the DURAPRO clichés easy to process in most standard UV exposure units (a unit equipped with vacuum frame is best). Since all UV exposure units do vary in light intensity, it is necessary to determine the optimum exposure time to create the proper etch depth (usually around 25 micros) of a DURAPRO cliché. By using the PROSERIES 21 Step Grey Scale, you can properly calibrate the exposure times required for both the first and second exposures of the cliché using the tint screen.
