Chroma/Tech PR is high solids offers good buildup with fewer coats, saving time and providing more screens per gallon. Chroma/Tech PL speeds up the entire process: coating, dry times and exposure speed.
Photopolymer – These are typically the fastest
exposing emulsions, with many exposing correctly from 30-50 seconds. The shortest times can be seen when using a
newer LED-type exposure unit.
Dual Cure – If you have established a good exposure
time with photopolymer emulsions, you can typically add 90 seconds (1.5
minutes) to that time for most dual cure emulsions.
Diazo - If you have established a good exposure time
with photopolymer emulsions, you can typically add 210 seconds (3.5
minutes) to that time for most diazo emulsions.
