Printing ink ink color matters needing attention

First, the deployment of primary ink is divided into three kinds of monochrome, inter-color and complex color. Monochrome refers to the mixture of a primary color ink; inter-color is made of two primary color inks; complex color is made of three primary color inks. All inks formulated with diluting agents are called light-colored inks. The following three points should be taken into account when deploying: White ink is not needed as diluting agent; white ink is the main color when adding color, and color ink is added in an appropriate amount; Accurate judgment.

Second, special color inks include gold/silver ink, pearl ink, and luminous ink. After the gold/silver ink is opened, it must be used in time, otherwise it will be easily oxidized and darkened. The commonly used gold ink is three kinds of gold, gold and red gold, the color is mainly based on gold powder, supplemented by color ink adjustment. There are also many kinds of silver inks. If a small amount of white ink is used, it will be silver white, and a small amount of yellow ink will be silvery yellow. Pearlescent ink consists of a pearlescent pigment and a bright varnish. Luminous ink is composed of phosphorescent pigment plus color ink and has the effect of nighttime light emission.

Third, avoid using too much color ink. Because the more ink, the farther away from the standard color, the worse the brightness, the worse the color gloss that is mixed out. At the same time, to use the same brand of ink, to avoid the production of iron in the printing, due to different manufacturers, different brands of ink mixed use escape color, transfer performance and other shortcomings.

Fourth, tinplate is divided into bright and dark surfaces according to the thickness of the coating and the surface processing technology. For example, a high-transparency color ink can be selected bright tinplate prints to enhance the ink's metallic luster; while the dark side or rough surface of the tinplate can choose to cover the strong color ink, such as white ink, increase its adhesion strength.
