First of all, we must understand the law of variation of trichromatic ink addition, analyze the color of the original manuscript, find out the main hue, and then modulate with the least kind of auxiliary color ink. Otherwise, the use of too many color types will make the ink dark and the gloss lower. To adjust the ink, use the same type of ink for the same factory. It is best to use the ink of the same type of pigment for modulation, so as to avoid chemical reflection or difficult affinity.

The addition of three primary colors: the primary color red contains a small amount of original yellow is red, with the gradual increase of the yellow phase into golden light red, orange, dark yellow, yellow. The original yellow with a little original blue is grass green, with the blue phase accentuated, gradually become green, brilliant green, green, dark green, dark green. The original blue contains a little bit of original red that is blue, and gradually becomes dark blue, ultramarine, blue and purple, and purple as the red phase increases. The original red and a little of the original basket is deep red. After the basket phase has become purple, the deepest red is purple, and the deepest basket is purple.

White ink, gray ink, and black ink have no hue and only have saturation. Adding white ink to any color ink will make the ink color luster rise, shine, and at the same time, the color will drop. If black ink is added once, it will make the ink glossy and dark in color. Change see below:

Attention should be used to adjust the balance of ink or electronic weighing scales, scraping scraping with an ink stick, adjust the ratio should be recorded, archived, in order to protect the consistency of the next ink ink color.
