Embodiment 1
[0021] A method for improving the positioning accuracy of silk screen printing by using laser, comprising the following steps:
[0022] (1) Prepare the glass substrate, and comprehensively clean the surface of the glass substrate;
[0023] (2) Perform full-page silk screen printing on one side of the glass substrate;
[0024] (3) On the position where other colors need to be overprinted on the silk-screened side of the glass substrate, use a laser to engrave the silk-screen of this position, and carve a rounded rectangle to expose the substrate;
[0025] (4) filling the first colored ink in the rounded rectangular position laser engraved in step 3, the color of the first colored ink is different from the color of the silk screen;
[0026] (5) On the first colored ink in the step 4, fix the position, and use laser to engrave the rounded rectangle that is reduced in proportion to the rounded rectangle;
[0027] (6) Refilling the pattern engraved in step 5 with a second ink ...

The invention relates to a method for improving screen-printing and overprinting position accuracy through laser. The method comprises the following steps: (1) completely cleaning a base material; (2) performing full-page screen-printing on one surface of the base material; (3) performing laser engraving on a part, needing to be overprinted with other colors, of the screen-printed surface of the base material; (4) filling first colored printing ink into the laser-engraved part; (5) positioning the first colored printing ink in the step (4), and performing laser engraving to obtain needed patterns; and (6) filling second printing ink into the patterns engraved in the step (5). The method has the beneficial effects that multi-color screen-printing and overprinting can be effectively achieved; other colored printing ink which is overprinted later can be quite accurately matched with the vacant position of original screen-printing ink; the patterns hollowed by the laser in the overprinted colored printing ink are overprinted with other colored printing ink, so that the relative position between the finally overprinted printing ink and the original screen-printing ink can be quite accurate, and the accuracy can be smaller than 5 microns.
Description
technical field [0001] The invention relates to a method for improving the positioning accuracy of silk screen printing, in particular to a method for improving the positioning accuracy of silk screen printing by using laser light. Background technique [0002] In the market, it is very difficult to screen print on the base material first, then overprint other color inks, and then overprint other color inks on other color inks, with poor precision and prone to misalignment. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages in the prior art of screen printing first on the base material and then overprinting other color inks, and then overprinting other color inks on other color inks, which is very difficult, poor in precision, and prone to misalignment And put forward a method of using laser to improve the accuracy of silk screen registration. [0004] The present invention is achieved through the following technic...
