Some views points on Printing process of the ink color mixing

In the printing process, no matter what kind of way printing ink, also no matter multi-color or monochrome printing, printing before the first problem encountered is the ink color blending, so that it is adapted to the needs of the product being printed, and therefore, often need to carry out the selection of ink color and blending. No matter how bright ink, if the operator does not understand some ink properties and color matching knowledge, mixed out of the ink can not achieve a satisfactory appearance and should be the level of quality. To this end, this article would like to introduce some color mixing methods for reference.

First, the principle of color matching

Any one of the colored by the hue, brightness and saturation of the three characteristics of the representation, and therefore in the process of color matching must take into account the above three factors. Despite the theory that black is the complete absorption of light, but black ink still has a gloss. Ink is pigment (color powder) and resin linker grinding from the pigment particles wrapped around a layer of nearly transparent resin oil, this layer of resin oil on the light has refraction and reflection, so we can feel the black ink printing on the substrate still has a certain luster. In the ink color matching process, according to the actual printing process, ink layer thickness, printing substrates and other conditions to determine the ink used. In the selection of ink (pigment ink canon), to consider the ink itself gloss, hue, coloring power, covering power.
Gloss can be measured with an instrument, but also with the naked eye to judge, usually in the process of color matching only with the naked eye observation. Gloss actually refers to the degree of ink printing sample irradiated by light in the same direction after the ability to reflect the size of the light. Its direct impact on the appearance of printed materials(canon 1200 ink refill), is a very important indicator. At the same time, in the selection of ink, to distinguish between the ink itself is bright, semi-gloss or matte type ink, to avoid mixing errors.
