Explain the introduction of PVC panel flat screen printing ink

Brief introduction of pvc panel flat screen printing ink: smooth and uniform ink layer, good dispersion, good hiding power, good overlap, good meshing and leveling, pure color and uniform fineness

Scope of application: soft / hard PVC, PVC artificial leather, PVC sticker, polycarbonate (PC) sheet, acrylic, wood products and paper / board, etc .;

Application industry: stationery products, travel shoes, plastic instrument panels, sign panels, stickers, stickers, transfer paper, etc.

Surface drying time: Natural volatilization for about 2 to 5 minutes at 55 ° C; hot air drying for about 20 to 25 seconds

How to use:

1. Fully stir before printing (about 10 minutes), stay for about 10 minutes and then use it better; 2. According to the needs of various factors in printing, you can add thinner (oil water) 15-40%;

3. For multi-color overprinting, the next color printing is required after the ink is dry.

4. An appropriate amount of thinner should be added during printing (note the supplement method)

5. Can be mixed with SS series ink (color mixing or color pressing up and down);

6. The screen can be opened with a thinner, and the printing will not start until the solvent on the screen has completely evaporated;

7. After the ink has been tested and determined to meet the requirements, then batch printing;

8. The basic performance of plastics varies with manufacturers or batches, which will affect the printing quality;

9. Some PVC plastics require the use of surfactants to ensure the fastness of ink printing

10. Long-term storage of ink will cause coagulation, if insufficient stirring, the printing effect is poor

11. Add an appropriate amount of defoamer, excessive addition will reduce the ink fastness

12. Improper addition of thinner or poor quality will affect printing quality

13. Excessive ambient temperature and humidity will affect the original ink quality

14. For leather products, the ink must be thoroughly dried before stacking and shipping

15. According to climate change, thinners with different drying speeds should be selected

16. For printing fine lines or dot graphics, slow-drying thinner should be used
