In the packaging and printing industry, in the actual printing, we often encounter the problem of color matching. If we do not understand the performance of ink and the basic knowledge of color, it is difficult to achieve the expected effect.Color Matching in Actual Printing
White ink, gray ink and black ink have no hue, only saturation. The addition of white ink to any color ink will increase the luster and brightness of the ink, and reduce the color at the same time. If black ink is added, it will make the ink shiny and gray. See the following figure for the change:Color Matching in Actual Printing
Note that the ink shall be measured by balance or electronic scale, and the sample shall be scraped with an ink scraping stick. When the ink is adjusted, the proportion shall be recorded and archived to ensure the consistency of the ink color next time.Color Matching in Actual Printing
First of all, we should understand the change law of the addition of three primary color inks, analyze the color of the primary color draft, find out the main hue, and then modulate with the least kind of auxiliary color inks. Color Matching in Actual Printing
Otherwise, if there are too many kinds of colors, the ink color will be gray and the gloss will be reduced. Note that the same type of inks produced by the same factory should be selected for ink modulation. It is best to use the ink of the same type of pigment to avoid chemical reaction or difficult affinity.Color Matching in Actual Printing
The original red plus a little original basket is dark red. After increasing the basket phase, it becomes purple. The deepest red is purple, and the deepest basket is also purple.Color Matching in Actual Printing

Change of addition of three primary colors: primary color red contains a small amount of primary yellow, which is bright red. With the aggravation of yellow phase, it gradually becomes golden red, orange red, dark yellow and medium yellow. Color Matching in Actual Printing
The original yellow contains a little original blue, which is grass green. With the aggravation of the blue phase, it gradually becomes emerald green, bright green, medium green, dark green and dark green. The original blue contains a little original red, which is medium blue. With the increase of red phase, it gradually becomes dark blue, ultramarine blue, Qinglian blue and purple.
