With the popularity of acrylic products, I can see its presence everywhere, such as banks, supermarkets, electronics market, mobile phone stores, tobacco hotels, jewelry stores and so on. But we may be most concerned about the shape of acrylic and beautiful beautiful pattern, how these patterns are printed up, there may be some friends will be curious, following the Shenzhen ceremony as a professional acrylic manufacturers to tell you how the acrylic products are silk screen patterns
1, for the four-color printing, should use the same size and stability of the aluminum frame (aluminum frame solid), the use of the network frame are strained with the same type and type of screen. The use of dyeing screen to help eliminate the moire, screen tension everywhere to uniform, and four-color printing of the four screen tension of the same tension.
2, the positive film (that is, film) on the acrylic products processing materials (here must be flat glass plate), and then exposure (the so-called exposure is placed in a very strong place for the sun), the stretch of the net Version on the negative film, and parallel with the image axis. If there is moire, turn the screen to the left or right, until the moire disappears, the general turn 7 ° can. The area where the moire is easy to form is located in the direction of the screen wire and at the intersection of the screen. The main colors and darker colors cause more problems with moire.
3, to achieve a perfect copy of the image of the most basic requirements of a transparent positive picture of the negative quality must be better, that is, the edge of the network to be neat, opaque and no scratches and so on. Color separators and the use of printing ink with the same color;
4, mesh video with high viscosity ink printing, the more fine the screen needs more concentrated color of the ink. The mesh image is printed with a high viscosity ink, and the finer the screen requires the darker the ink.
5, grinding a good squeegee for high-quality silk screen is essential, knife blade Shore hardness of about 70. The doctor blade should be set at 75 ° angle, if the angle of the doctor's knife was transferred too flat, Printed images may be blurred, if the angle is too steep, the risk of screen printing image deformation is large. Back to the ink knife should not be installed too low, if so, the film will be filled with excessive ink, printed matter easy to blur and rub dirty.
6, in the bulk of silk screen, you should first fixed a good screen into the ink test India, check the layout of the layout of the level of printing, ink, ink thickness, specifications, registration accuracy. If the registration accuracy is poor, can be adjusted according to the front of the fine-tuning knob in front of the frame; if the ink hue is wrong, check whether the wrong ink, and immediately replace; if the ink is bad, you can use the solvent to wipe the plate graphic part, The performance and the wettability of the substrate to be a certain improvement; if the tone of the text and the level of a greater difference, you should immediately replace the screen.
Above is the processing of acrylic silk screen in the processing of the text of the craft and production details, do not understand friends can also come to me to consult or visit the factory.
