1. Anti-counterfeiting label silk screen anti-counterfeiting mainly refers to anti-counterfeiting for the coating part and local part.2. It is recommended that the coating part should not be laminated as much as possible, because the lamination cost is high and it is difficult to cut and grind. Varnishing oil is the best way.3. When making self-adhesive labels, try not to varnish the entire part, just partially.4. The coarseness of the silk screen mesh affects the thickness of the coating, and the concentration of the diluent affects the beauty of the coating.5. The silk screen anti-counterfeiting technology of self-adhesive labels uses water-based screens for dripping anti-counterfeiting, and others generally use oil-based.6. The mesh of the silk screen screen used is generally 250-350 mesh. In theory, the larger the mesh of the silk screen screen, the stronger the effect and the thicker the coating.7.In actual use, it is found that the thicker the ink, the more delicate the silk screen pattern. If it is not diluted enough, it may also peel.8. Silk screen printing is related to layout and design. The larger the layout space, the easier it is to adjust the position during silk screen printing. Silk screen printing is also related to the weather. Too much humidity or too high temperature will affect the effect of silk screen printing. Generally, slow drying water or extra slow 783 should be added when the temperature is high, and the drying water should be accelerated when the temperature is low.9. Silk screen printing should pay attention to the customer's requirements for individual labels and have a certain relationship with coding. If the coating is printed on the coating, it does not matter if the coating is thinner; if there is no printing on the coating, the coating should be thicker; in addition, the font should be as clear as possible when coding, but the strokes should be as thin as possible.10. Silk screen printing is related to the order of label placement: pay attention to distinguishing between those with serial numbers and those without serial numbers.11. Silk screen printing should pay attention to the material problem. Different materials have different inks and methods.12. Silk screen printing should pay attention to whether the post-processing needs to be laminated. If the silk screen part is easy to fall off or wipe off, it needs to be laminated.13. When printing silk screen, pay attention to whether to use color. Generally, offset printing is better, and often offset printing cannot print but silk screen can print, so it is often said that silk screen can do everything.14. The silk screen printing technology of self-adhesive labels requires understanding of the performance of ink, screen plate, position, plate adjustment, plate repair, and plate washing.15. When printing silk screen, pay attention to the surface not to be smeared or bubbled;16. It is worth reminding that it is generally recommended to do it all at once when doing drip anti-counterfeiting, because this kind of screen often has a slight pause in the middle and may not be used.17. When printing silk screen, pay attention to the production order. If it is temperature-change anti-counterfeiting, pay attention to whether the temperature change disappears or changes color; pay attention to whether the temperature change effect is reversible or irreversible.18. The performance criterion of silver powder on the surface of silk screen is: it can be scratched with fingernails and cannot be wiped off with fingertips.
