The use of dampening solution in brochure printing factories

Adding dampening solution should not be used in terms of environmental requirements, but it has low dynamic surface tension and increased viscosity. To ensure ink balance, 1% -15% alcohol dampening solution can be used,

Alternatively, other alcohol solvents can be added to the dampening solution, which is still essential in non absorbent printing to improve printing quality. It is recommended to maintain the pH value of the dampening solution at 5.5-60 and the temperature at 9-15 ℃.

Due to the fact that synthetic paper does not have the absorption properties of paper, the water supply on the printing plate should be reduced by 10% -20%, otherwise it will affect the dryness of the ink and the manufacturing of its surface. In short, due to different synthetic techniques,

It also increases the difficulty of the printing process. In terms of ink absorption, because the amount of ink transferred by ordinary offset printing is relatively small and can be fixed into a solid print at once, synthetic paper is more suitable for transferring more ink to flexographic printing,

Gravure printing and screen printing technology. When printing, do not directly print large areas of solid material, and control the speed and electrostatic discharge during actual printing. We must have a suitable selection of materials and processes for its surface properties during synthetic paper printing.
