photopolymer is a polymer specifically developed for contact printing
that hardens under sunlight (ultra violet). The unexposed parts are
called monomers, which are molecules that are not connected between
them and to wash with water (and a little sodium carbonate) are easily
undone. When the material is exposed to light, it polymerizes molecules
bind to each other, hard, and water will not undo.
The development of photopolymer begins with the image processing in the
design department, then assembled the data bands and films the negative
cliche. Then the technician makes the polymer with specialized
machinery. Once facts are mounted on a frame Astralon and are ready to
serve the customer.
