The principle of ink color

The principle of ink color

When a printing manufacturer conducts a printing operation, it usually encounters some special colors, and the purchased ink is different from what is needed. At this time, the manufacturer needs to modulate the spot color ink. To modulate spot-color inks, you must understand the principle of true colors. For example, yellow and blue blends can be green; yellow and red blends can be orange or orange; primary colors blue (usually called sky blue) and purple (also called Qinglian) can be formulated to produce dark blue, medium blue, etc. Wait.

When spot color inks are dispensed, care must be taken to ensure that: 1. When spot color inks are dispensed, they cannot be mixed with different manufacturers' inks. In particular, they must not be mixed with compound inks in order to avoid causing the resin to precipitate and make the inks unusable. . 2. The ink with similar colors will be blended, then the color of the transferred ink is brighter, and the ink with larger color difference will be darker than the color of the ink. 3, when color matching, should reduce the type of ink, because the more types of ink, the more will reduce the ink's vividness and saturation. 4, when the deployment of light-colored ink, should be based on white ink, a small amount of ink added to the original color. 5, plastic film is non-absorbing material, can not use thinner to dilute the color ink, but should add white ink to dilute.

The printing manufacturers can modulate the spot color inks themselves. Because the mixing and coloring conditions are not available, the color to be extracted may appear large deviations each time, and the colors are not stable. Generally for difficult-to-adjust, long-term use, large-volume spot color inks, it is best to contact with the ink factory, custom spot color inks, and tell them the speed of printing, the depth of the printing plate, in order to protect the relies on the spot color ink Meet the requirements once and for all. Spot inks prepared by the ink factory are generally stable and easy to use.
