Abstract

The invention belongs to the technical field of developing solution preparation and especially relates to a developing solution for a thermo-sensitive positive CTP plate. The developing solution contains the following components in parts by weight: 85-112 parts of main developing agents, 7-11 parts of inhibitors, 10-14 parts of wetting agent, 5-11 parts of buffering agents, 2-6 parts of de-foaming agents, 28-36 parts of solvents and 780-850 parts of deionized water. According to the invention, an efficient surface active agent is matched with various organic acid salts in the components, so that the damage of the surface active agent to the hydrogen bond in the components is reduced, the turbid condition after the developing solution is used for a period of time is relieved and the developing solution has the advantages of good developing effect and excellent turbid condition after use.

Description

technical field [0001] The invention belongs to the technical field of developing solution preparation, and in particular relates to a developing solution used for thermal positive CTP plates. Background technique [0002] CTP plate-making technology is divided into photosensitive CTP plate-making technology and heat-sensitive CTP plate-making technology. Among them, thermal CTP plate-making technology is the most mature, stable and best printing technology. It has high printing quality and can be used in the future. Advantages of indoor operation. [0003] Thermal CTP technology can be roughly divided into four steps: plate making, coating, developing, and printing. The purpose of developing is to remove the photosensitive layer that has been decomposed by light on the plate, and use dilute lye as the developer to develop the plate. , On the plate, there is no lipophilic slightly raised relief image formed by the photosensitive layer. Whether the photosensitive layer of t...
