Plate Processing

Photopolymer plates work by exposure to UV light through film negatives (it’s crucial for commercial work to have a vacuum sealed unit to press the film to the plate or you may get poor results) which imposes the image and makes the polymer ‘cure’ whilst the unexposed area can be washed away.

It is vital therefore to protect plates pre and post exposure from UV light.

Washing the plates after exposure is done via LIGHT BRUSHING IN CLEAN WARM WATER apporximately 20-25°C (68-77°F) and takes around five minutes for manually or three to four minutes mechanically. Brushes must be soft to avoid damaging the plates which require drying with warm air and a second exposure in the UV unit to cure the plates.

Main Exposure is between three minutes thirty and five minutes thirty. Hot air drying takes approximately ten minutes at 60-70°C (140-158°F) – nice in the winter! Post exposure in the UV unit takes about another ten to twenty minutes depending on main exposure time.
