The mastery of high-quality plexiglass (acrylic) screen printing technology is the core goal of plexiglass (acrylic) processing plants. The highlights of the organic glass (acrylic) screen printing process are as follows:
1. The negative film is placed on a glass plate, and then exposed. The stretched screen plate is placed on the positive plate and parallel to the image axis. If there is a moiré pattern, rotate the screen to the left or right until the moire disappears. Generally, turn it 7°. The area where the moire is easily formed is located in the direction of the screen mesh and at the intersection of the screen. Major colors and darker colors cause more problems with moire.
2. One of the basic requirements for perfect image reproduction is that the quality of the transparent negative positive film is better, ie the edge of the dot should be neat and opaque. The color separation sheet is the same color as the printing ink used.
3. The ground squeegee is critical for high-quality printing. The blade has a Shore hardness of approximately 70. The squeegee should be set at an angle of 75°. If the angle of the squeegee is adjusted too flat, the printed image may be blurred. If the angle is adjusted too steeply, the risk of deformation of the screen printing image is large.
4. For four-color printing, the same size and stable aluminum mesh frame should be used, and the used mesh frames are all stretched in the same type and model mesh. The use of dyed wire mesh helps to eliminate the moire, and the tension across the screen is uniform, and the four screen printing screens have the same stretch tension.
5, mesh tone image printing with high viscosity ink, the more fine the screen needs more concentrated color ink.
6. The ink-return knife should not be set too low. If so, the film plate will be filled with excess ink, and the prints will be easily blurred and flawed.
7. Using UV ink, the tonal range of the mesh adjustment image should be selected as 5% to 80%, and the scratch hardness of the squeegee should be 75. In order to control the UV inks in the color overprinting, it is recommended to print in the color order of cyan, magenta, yellow, and black. When using UV ink, the screen thickness does not exceed 5um.
