Do you know how the glass screen printing machine handles the ink problem? Next, the editor of the Vility screen printing machine manufacturer will explain to you the basic problems of handling ink:
Before the screen printing of the glass screen printing machine, the ink should have good application and printing adaptability, and appropriate deployment should be made when necessary. Our company has focused on glass screen printing machines for more than 10 years, and the quality advantages have obviously been recognized by our customers. Everyone introduces the ink processing of the glass screen printing machine.
First. Toning. Before matching the ink, you should calculate the ink consumption of each color print to make the amount of ink appropriate. Especially for the two-liquid reactive ink, the ink adjustment should be calculated according to its curing speed and printing speed. quantity.
To obtain the correct color, the ink adjustment should be carried out under stable natural light. At the same time, it is not possible to count the colors and observe them together to avoid the influence of illusion. When configuring fresh ink, the addition of dark ink should be gradually close, and avoid adding too much at a time , And then use a lot of light-colored ink to remedy. At the same time, the mixed hues should be minimized. The more hues, the larger the grayscale.
Second, pay attention to the color change before and after drying. For example, on light-colored substrates with large ink absorption, the ink color after drying is often light; the color difference of the wet state, the dry state and the foamed state of the foamed ink is large. The color of the ceramic ink changes after firing; the white ink will turn yellow at high temperature. Such color changes require the printer to accumulate experience and samples in practice, and make their own color standards.
Third, the color adjustment of the screen printing ink (printing material) of the glass screen printing machine is a link that cannot be ignored in the screen printing production process. The basic principle of the adjustment is inseparable from the basic principles of the additive color method of shade and the color subtractive method of color materials.
Fourth, mixing any two of the three primary colors of the colorant in equal amounts can produce a hue of the three primary colors of light. From the perspective of color, these three hues are called secondary colors (or second colors), such as The green formed by the mixture of yellow and cyan is the secondary color. The hue produced by the mixture of the secondary color and the secondary color is called the secondary color (or the third color). The secondary color and the secondary color ink formed by the mixture of the three primary color inks The mixed color and complex color.
