A Photopolymer plate is a metal plate coated with a light sensitive film and is ordinary made to use in graphic industry. This is a non-toxic process.

Always be careful when handling chemicals. Read the health and safety instructions.

In my work I used KM 73 plates from Printight. This is a metal plate coated with a light sensitive film.


1Prepare positive film. Drawings, photocopies and laser or inkjet prints on transparent film may all be used. I work with Canon transparent to use with ink jet bubble printer. Canon BJC 8200 does a great job.

2Expose the plate in with this positive film in UV light for a couple of minutes. Then expose a positive stochastic raster in the plate for about half time of the positive film. Philips HPR 125 is a good start for the beginners but for the best results is to use a vacuum frame with UV light.

4Dry the surface of the plate with a fan heater or hair dryer for 5 minutes on a warm setting.

5Before inking the plate you must harden the polymer. Put the plate back again in the UV light in about 10 minutes without the positive and raster. Now, the plate is finished and ready for inking.

6In my work I use ink made for graphic art called Charbonel NOIR RSR. This is black ink and gives very good results. Mix the ink with Easy Wipe compound and a little bit of light oil. In my work I ink the plates with a roller made for graphic art. Then wipe the plate using tarlatan. Tarlatan is an open-meshed woven material also used for bookbinding. Fold it to form a ball and used it to wipe off the plate with a quick circular movements.
