The basic knowledge of packaging and printing color deployment

In the packaging printing ink system, the binder is colorless or with a micro-colored liquid, the refractive index and water are close, so the binder has a certain degree of transparency. When the pigment and filler are added, the color and /or material block the light. Shooting, resulting in changes in the optical properties of the ink.

When daylight enters a yellow color ink ink film, it means that it absorbs the blue spectrum of sunlight and emits yellow and green light. When the reflected yellow and green light encounters the blue pigment particles, the blue light reflected by them tends to absorb only the green light. After a series of reflections and refractions, only the green ink ink film is reflected. Therefore, we call this color mixing of printing inks to be subtractive mixing ( receive each other's desired wavelengths and not be reflected by the absorbed spectrum ) , which is the origin of mixed colors ( or polychromatic colors ) .

In China's packaging printing ink industry due to the use of the principle of subtraction, so the use of three primary color complementary.

We use a variety of printing ink color shades to compound many colorful ink colors.

If the color of the package printing and decorating design is fully conceived, from the three primary colors of yellow, magenta, and green to three colors of red, green, blue, and then to four-colored purple, bronze, olive green, and black, Can be combined into a new form of expression, as people already know if the different ink color hue ( hue ) , different ink lightness and different ink color saturation combination together, it will also give a beautiful soft And the feeling of harmony.

Looking at the color of the domestic and international packaging printing ink color cards, with the exception of the three primary colors, the vast majority are composite colors. The deployment of complex ( combined ) colors is itself a color science, and the color of the prepared packaging and printing is ultimately based on our visual inspection. To verify its effectiveness, good, bad and pros and cons. The use of packaging and printing to decorate the color of the goods we need, decorate a dazzling array of colors, and constantly adjust the work and living environment, will give people a positive stimulus, is conducive to work and quality of life.

There are several colors in the packaging and decoration of the same environment, so the coordination between colors is always the subject that we have not studied. Such as complementary ( red and green ) colors ( two colors equal to white ) , sometimes with a bad taste will give people a tacky feeling, with a good deployment, will give people a strong and eye-catching feeling. Light yellow with reddish-brown, due to the close color between yellow and red, the similar color gives a harmonious beauty. There is also a combination of dark green and light green, fresh and dazzling. Using the method of achromatic and color matching at the same time, it gives a bright feeling and protects the eyesight. When the red, white and blue colors are the same, they appear on a single package, giving people the impression that the red is warm, the white is pure, and the blue is dignified, reflecting the beauty of a kind of goods and materials.
