1. Anti counterfeiting label silk screen anti-counterfeiting mainly refers
to the anti-counterfeiting of coating parts and local areas.
2. It is recommended not to apply lamination to the coating part as much as
possible, as lamination is expensive and difficult to cut and grind. Applying
gloss is a good method.
3. When making self-adhesive labels, try not to apply overall gloss, and
only apply partial gloss.
4. The thickness of the coating is affected by the thickness of the screen
mesh, while the concentration of the diluent affects the aesthetics of the
coating.
5. The silk screen anti-counterfeiting technology for self-adhesive labels
uses water-based mesh plates for drip anti-counterfeiting, while others
generally use oil-based ones.
6. The mesh size of the screen screen used is generally 250-350 mesh. In
theory, the larger the mesh size of the screen screen, the stronger the effect,
and the thicker the coating.
7. In practical use, it has been found that the thicker the ink, the finer
the silk screen pattern. If the dilution is not enough, it may also peel.
8. Screen printing is related to layout and design, and the larger the
layout space, the better the position adjustment during screen printing; Screen
printing is also related to weather, as being too humid or too hot can affect
the effectiveness of screen printing. When the temperature is generally high,
slow dry water or extremely slow 783 should be added, and when the temperature
is low, fast dry water should be added.
9. Silk screen printing should pay attention to the customer's individual
requirements and coding, which have a certain relationship. If the coating is
printed with thin dots, it is also okay; If there is no printing on the coating,
the coating should be thicker; Additionally, when typing, the font should be as
clear as possible while the strokes should be as fine as possible.
10. The order of silk screen printing and label placement is related: pay
attention to distinguishing between those with and without serial numbers.
11. Silk screen printing should pay attention to material issues, as
different materials have different inks and methods.
12. When screen printing, attention should be paid to whether the
subsequent processing requires lamination. If the part of the screen is prone to
detachment or erasure, lamination is necessary.
13. When screen printing, attention should be paid to whether color
matching is necessary. Generally, offset printing with color matching is better,
but often screen printing that cannot be printed by offset printing can be
printed. Therefore, it is often said that screen printing is omnipotent.
14. The screen printing technology of self-adhesive labels requires an
understanding of the performance of the ink, as well as the screen, position,
adjustment, repair, and washing of the boards.
15. Silk screen printing should pay attention to the surface not being
burnt off or bubbling;
16. It is worth reminding that when doing drip anti-counterfeiting, it is
generally recommended to complete it all at once, because this type of online
version often has a slight pause in the middle and may not be sufficient.
17. Silk screen printing should be made according to the production order.
If there is a temperature change in anti-counterfeiting, attention should be
paid to whether the temperature change disappears or changes color; Pay
attention to whether the temperature change effect is reversible or
irreversible.
18. The standard for measuring the performance of silver powder on the silk
screen surface is that it can be scraped open with a fingernail, but cannot be
wiped off with a fingertip.
