Shanghai printing plate-making process in detail: 1. Developing: recommended D-23, D-76 developer D-23 low-contrast particle developer D-76 developer particles of water (52 ℃) 750ml metol (US more) 7.5g 2.0g of anhydrous sodium sulphite 100.0g of the above order shall hydroquinone (strong security) 5.0g 2.0g Water to 1000ml borax dissolved when formulated formulated liquid used without dilution, the temperature 20 ℃, developing time 6-- 10 minutes. Film contrast varies with the strength of the developing stirring, stirring the faster, the higher the contrast. The development process should be controlled stirring intensity. If necessary, the developing time may be extended to increase the film speed. 2, stopped Movies: This is to stop the development process, after the film was immersed in a developing solution of 2% acetic acid, 20 seconds.
