In order to smoothly carry out screen printing, it is necessary to prepare the printing materials, substrates, printing plates, etc., and to ensure that the printing machine can work normally. If the type of ink is suitable, whether the ink color, viscosity and thinner are appropriate; the size, type, quantity of the substrate, whether the surface needs to be treated; whether the components of the printing machine are operating normally, the surface of the printing table is flat; whether the size of the printing plate is Accurate, accurate or not. Color adjustment Before the ink-filling machine is equipped with ink, the amount of ink consumed per color shall be calculated first, so that the amount of ink dispensed is appropriate. Especially for the two-liquid reaction type ink, the amount of ink to be adjusted should be calculated according to the curing speed and the printing speed. 2. Ink coloring method The so-called pad printing color is to combine two or more colors, or a small number of colors in addition to the main color to form a combination of colors. When the color ink is used before the first use, the color to be prepared on the color sample is separately exposed, and the original color is correctly identified as the primary color, the intermediate color, or the complex color. Pay attention to three points when printing ink in the printer: a. When adding ink, try to add less color inks. The less the color inks, the better the mixing effect. b. With the principle of “from shallow to deepâ€, no matter whether you are preparing light or bright colored inks, be careful when the hue is close to the sample. c. Some pad printer inks are dried by drying, lighter drying is lighter than undried, and darker after drying. In addition, whether or not the color tone of the ink differs before and after drying at the time of printing is a problem that is easily overlooked.
