What are the processing techniques for glass inks?

1. Pay attention to the color change before and after drying. For example, on the light-colored substrate with large ink absorption, the dry ink color is often light; the wet, dry and foamed three-phase color difference of the foamed ink is large; After the ceramic ink is burned, the hue is changed; the white ink turns yellow after being heated at a high temperature. Such discoloration rules require the printer to accumulate experience and samples in practice and make their own color code.

2, coloring. Before the ink is mixed, the ink consumption of each color print should be calculated first, so that the amount of ink dispensed is appropriate. Especially for the two-liquid reaction type ink, the ink amount should be calculated according to the curing speed and printing speed. 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, and should not be added once. More, then use a lot of light ink to remedy. At the same time, the mixed hue should be minimized, the more the hue, the larger the gray scale.

3. The color matching of screen printing ink of glass screen printing machine 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 color method and color-reducing method of color material. Fourth, the color of the three primary colors can be mixed in any two colors to produce a certain hue of the three primary colors of light. From the perspective of color, the three hue are called inter-color, such as the green formed by the mixture of yellow and blue, which is the inter-color. The hue produced by the mixing of inter-color and inter-color is called the complex color. The color and complex color of the three primary colors of color and complex color are mixed.
