The following is Shenzhen Dongfang Longke’s answer for you: PVC printing, ink selection, bag making, adhesion, use, etc. are all subject to certain restrictions. PVC label design should pay attention to 20 points when printing.

1. Avoid lines thinner than 0.1mm.

2. Avoid using colored words (that is, the highlighted words are composed of two colors). In this case, a black border or other colored border is added with the customer's permission. But the edge width is greater than 0.25~0.3mm.

3. When registering lines and colors, it is generally required that the line width should not be less than 0.3mm, and the color should be extended to the middle of the line.

4. When three or more colors are overlapped, try to change them to two colors and spot colors.

5. It is best to use spot colors for large-area background colors and avoid using color separations for printing. Color separations can easily cause color difference, especially blue and yellow, red and yellow.

6. The minimum critical value for any color to hang on the net is 20%.

7. The white background of the text is generally thickened to about 0.3mm.

8. The depth of special green version, special purple version, pearlescent version, matte version, white version, etc. must be greater than 45μm.

9. The yellow version can be screened or edge blurred when needed, for example, when yellow and red are combined with hollow words or yellow and red are used to overlap text.

10. Barcodes are generally placed perpendicular to the horizontal direction, that is, vertically, to prevent deformation when shrinking and causing unrecognizability or misreading.

11. The distance between the barcode and the palm edge is generally greater than 5mm to prevent shrinkage and deformation.

12. When the white plate is expanded and contracted, the upper and lower can be expanded by 0.3mm, and the left and right can be expanded by 0.4mm.

13. Try to avoid gold, silver and color back-expansion, which will give people the feeling that the edges of the text are dirty.

14. Avoid using gold or silver plates as transition nets, as the transition effect is not obvious.

15. When arranging the color sequence, in addition to adhering to the principle of putting the three primary colors C, M, and Y together, you must also pay attention to the closer the two colors that are more difficult to register, the better.

16. All dots with less than 10% of the dots in the electrograph should be removed, because the ink with less than 10% of the dots cannot be transferred.

17. When color registration is difficult, it is best not to exceed 2 pieces of horizontal pattern or use a film with a door width not exceeding 600mm. When the door width of PVC film exceeds 650mm, its thickness and straightness will be more difficult to control. , often leads to the generation of many defects and brings difficulties to printing.

18. When printing portraits, it is best to print on a newly produced base material with fewer missed printing spots, because there is no precipitation of additives on the surface of the newly produced film.

19. Relevant text, barcodes, marks, and trademarks must comply with relevant national regulations.

20. The position of effective graphics and text is generally controlled within the tolerance of x2-2mm under the folding radius to avoid being covered when palms are closed.
