Golden silver are offset printing and embossed technology is difficult to control link, the reason is that gold and silver pigment particles than other ink pigment particles of coarse, printed on the paper links is expected to be absorbed as a part of the first oxidation conjunctival reaction at the same time, in the process of dry pigment particles precipitate easily from the links of material, not firm adhesion, and then the other color printing ink on the stack of color to gold and silver ink, due to its viscosity, easy to stick color ink out false or show the phenomenon, cause waste and defective products.
According to the actual situation, the technical personnel to explore the silver printing ink, in this kind of ink to join by the black ink and thinner and mixed silver ink, such both neither can change color, but also overcome the problem.
Using the printed in gold ink slightly pale yellow ink, effect is obvious.Sometimes black color ink stack onto the metal ink black degree is not enough, you can use the dark blue ink amount added to the black ink to make, problem is solved.
