negative PS offset plate

Developer: Kodak Goldstar Premium plate developer 100% Develop temperature: 22-24℃ Develop time: 30-35 seconds. Finishing: KG-2, KG-2S To increase the hydrophilicity of the non-image area and prevent the plate from fingerprint and other contamination, you should use gum solution (KG-2 or KG-2S, 8%-11% made by Gum Arabic) immediately after image removing. Wipe the gum solution on the developed plate and dry it. Gum solutions made by synthetic polymer are difficult to wash away
