In the design of the printing calendar, in order to improve the effect of packaging printing, the surface brightness of the packaging box is often increased. One of the common practices is to use special paper, such as gold and silver jam paper, to print on such paper in order to obtain higher gloss. degree, It is often necessary to use transparent ink to print. Transparent ink is all or most of the dye used to make ink, its cover is very low, high transparency.
Due to the high transparency of transparent inks, aluminum coatings are generally combined after printing, so that the luster of aluminum membranes and the luster of inks combine with each other, reflecting more vivid colors. Products printed with transparent ink, viewed from different angles, the color phase will have a more obvious change, in different light sources to observe the difference will be greater. In the deployment of this type of ink, we must first understand the customer requirements, in order to deploy the ink according to the same process, in a similar environment to observe the ink phase.
The transparency of transparent ink is determined by the dye and binder, the dye plays a major role, and the binder has less influence. In general, the ink that uses dye as a colorant has higher transparency than the ink that uses pigment as a colorant. Sometimes due to other needs, some pigments will be mixed in the dye, and the transparency of the ink will be reduced.
