First, coloring. Before dispensing ink, first calculate the ink consumption per color of printing, so that the amount of ink is appropriate. Especially for two-liquid reactive ink, the ink should be calculated according to its curing speed and printing speed. the amount.
In order to obtain the correct color, the ink should be carried out under stable natural light, and the color should not be juxtaposed to observe and be protected from the illusion. When the fresh ink is configured, the dark ink should be gradually added, so avoid adding too much at a time. Then use a lot of light-colored ink to remedy. At the same time, try to reduce the mixed hue. The more the hue, the larger the gray scale. Second, pay attention to the color change before and after drying, such as the light-colored substrate with large ink absorption. The color of the ink is often light; the color difference of the wet, dry and bubbled three phases of the foamed ink is large; the hue of the ceramic ink is changed after firing; the white ink turns yellow after high temperature. It is necessary for the printer to accumulate experience and samples in practice and make their own color code.
Third, the color matching of silk screen printing ink (printing) of screen printing equipment is a link that can not be ignored in the silk screen production process. The basic principle of blending is inseparable from the basic principles of color adding method and color reducing method. Fourth, in the three primary colors of the color material, if any two colors are mixed in equal amounts, a certain color phase of the three primary colors of the light can be generated. These three color phases are called a color (or a second color) from the color point of view. For example, the green color formed by the mixing of yellow and cyan is the inter-color. The hue produced by the mixing of the inter-color and the inter-color is called the complex color (or the third color). The three primary colors are mixed into the intermediate color and the complex primary colors. The color and complex color of the ink mixed.
