To help you we’ve developed a price calculator so you see how much plates cost. Enter your plate type and the dimensions and the price will be given. Compare this and see how we’re doing.
Our commitment is to provide the best value we can to letterpress printers – the cost of plates includes Free Posting to the UK mainland.
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.
We make plates with the UK distributer of the Toyobo Photopolymer Plate. Lyme bay Press carry the same equipment and develop plates in the same way. If at any time we cannot look after you, which is rare, we may put you in touch with Lyme Bay Press – but if you have any questions please feel free to ask away.
