Abstract

The present invention proposes a precision and high-quality printing process, which includes the following steps: S1: processing of the plate base; S2: coating of the photosensitive adhesive layer; S3: determination of the best exposure time, first, calculate the approximate exposure time ; Then expose according to 50% of the screen of the approximate exposure time; then cover 1 / N of the screen, and then expose according to 25% of the approximate exposure time, that is, cover 1 / N more each time, and follow the previous exposure time Expose 50% of the exposure to get N areas with different exposure levels. After the screen is washed, dried, and proofed, the best exposure time is obtained; S4: Printing according to the best exposure time; S5: Printing at 70 When ‑80 blocks, replace the developer. The operation steps of the present invention are scientific and reasonable. The optimal exposure time is determined before the formal printing, which reduces the generation rate of waste plates in the printing. The superimposed exposure time is successively reduced by grading, so that multiple exposure times can be obtained at one time. Accurate test results, saving time, labor and cost.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a precise and high-quality printing process. Background technique [0002] Printing means exposure. Printing is to photocopy the pictures and texts on the film, sulfuric acid paper and other carriers with high transparency, which are loaded with pictures and texts, to the screen plate, PS plate, Work on materials such as resin plates. Coat a layer of photosensitive film on the surface of the screen plate, PS plate, and resin plate and then dry it, cover the film with images on it, irradiate the film with strong light, and the image on the film is exposed and photocopied to the photosensitive film on the plate. , This exposure photocopying process is commonly known as printing. [0003] Before the formal printing, the exposure time needs to be determined, but due to the routine operation, it is necessary to carry out multiple printing tests to get the correct printi...
