Abstract

This invention provides a environment protective PS plate printing ink and photoresist remover, which features the composition of 0.5-2 % (by weight) of organic surface active agent, 0.5-2 % of inorganic surface active agent, 10-25 % of organic solvent, 3-15 % of acids, the others is water. Said invention also provides relative preparation and use method.

Description

technical field

[0001] The invention relates to the regeneration of PS plates, in particular to an ink and a photosensitive adhesive stripper used for the regeneration of environment-friendly PS plates and a preparation method thereof. Background technique

[0002] my country's printing industry has formed a printing method mainly based on offset printing through research and development and introduction of technology. At present, most of the plates used in offset printing are PS plates based on metal aluminum plates, except for a small amount of zinc oxide paper-based plates for light printing. my country's PS version has developed rapidly, and the output in 2004 has exceeded 100 million square meters, accounting for more than 20% of the world's total output. The production of PS version consumes a lot of metal aluminum. According to statistics, my country now uses 130-140 million square meters of PS plates every year, and needs to consume more than 100,000 tons of metal ...
