Abstract

The invention discloses easy-to-prepare PS plate developing liquid and a preparation method thereof, relating to the field of printing. The developing liquid comprises the components with contents as follows: 51-55g / L of potassium hydroxide, 155-175g / L of sodium silicate, 9-11g / L of sodium phosphate, 20-25g / L of sodium dodecyl benzene sulfonate and the balance being ion water or distilled water. The easy-to-prepare PS plate developing liquid has the advantages of high developing capability, high stability, long service life, easiness in clearing of residual alkaline liquid, uniform developing and the like; furthermore, the influence on no photosensitive coating caused by erosion is low, and a photosensitive layer of an image-text part cannot be eroded by the developing liquid.

Description

technical field [0001] The invention relates to the field of printing, in particular to a PS plate developing solution which is easy to manufacture and a preparation method thereof. Background technique [0002] Development is an essential link in the printing industry, and it is also an important link that affects printing quality. Many people think that the development of PS plates is just to put the sun-dried PS plates in the developing pool and shake them for a few times, and then rinse them with water. Apply developing ink, remove dirt, and apply peach gum. There is no technology to talk about. The fact is that the development of the PS plate has technical requirements. It is a chemical reaction process that uses the property that the photosensitive layer that has not seen light is insoluble in dilute lye, while the photosensitive layer that has seen light is soluble in dilute lye. The developing solution is the key to affect the developing effect. The developing solut...
