Abstract

The invention relates to a novel preparation method for a developing solution. The method comprises the following steps: (1) stirring and dissolving salicylate in benzyl alcohol, thereby obtaining a solution a; (2) increasing the temperature of the solution a to 40-46 DEG C, adding a main developing agent formed by mixing isopropyl amine with triethylene tetramine, and stirring for 18-25min at the stirring rate of 800r/min, thereby obtaining a solution b; (3) maintaining the solution b at 40-46 DEG C, successively adding a wetting agent, glycerine ethoxylate and 2-phosphono butane-1,2,4-tricarboxylic acid, and stirring for 8-13min at the stirring rate of 200r/min, thereby obtaining a solution c; and (4) adding deionized water and citrate into the solution c, uniformly stirring, and adjusting and maintaining the solution temperature within 22-25 DEG C, thereby finally obtaining the developing solution. The preparation method has the advantages of simple and effective operation steps, excellent developing effect and difficulty in turbidity of the prepared developing solution.

Description

technical field [0001] The invention belongs to the technical field of preparation methods of developing solutions for heat-sensitive CTP plates, and in particular relates to a preparation method of novel developing solutions. 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. Whe...
