First of all, the master printer is required to strictly follow the standard of "less water and less ink" in the printing process. It is forbidden to have too much water and ink, so as to reduce the water absorption of ink and paper, and reduce the emulsified state of oil-in-water formed by ink, which will lead to the destruction of ink structure and the exposure of pigment on the paper surface.
Secondly, select high-concentration ink with fast conjunctival oxidation and good friction resistance, reduce the thickness of ink layer after printing and dry the surface of ink film.
Thirdly, the proportion of fountain solution should be appropriate, and alcohol and stock solution should not be added too much. The PH value should be controlled between 5.0 and 5.5, and the alcohol content should be controlled between 8- 15% (depending on the alcohol quality, climate and specific workshop conditions), but it is recommended not to exceed 15%.
Fourthly, the paper stack thickness should not be too high, generally 200-500 sheets/stack, depending on the ink layer thickness.
British Sun Nomeia ST-800 series quick-drying and wear-resistant matt paper, aluminized paper and gold and silver cardboard are advanced environmentally friendly offset printing inks.
SUNSURE NOMEAIA ST-800 Ink
Bright colors, delicate images and strong layering;
