I have been spending some time to learning a new print making technique by using Polymer plate.
Photopolymer is photosensitive material in sheet form that is exposed to UV lights through a negative film. The light shines through the clear sections of the film and hardens the polymer. The plate is washed out with water. The exposed areas are left to form the relief and the unexposed is washed away.
This technique was originally used for production printing process, but over the past a few years, it has been more and more popular in the print making world. More and more artist using this plate to create near photo etching effect.
