Photochromic ink series manual
Product name: photochromic ink
Type number: DSK series
Packing: 1KG/ can
I. Introduction of product features:
Photosensitive optical color-changing ink is the latest anti-counterfeiting ink, printing color blocks show a pair of colors, such as: no-blue, no-red, no-purple, etc.; Under indoor white light, the product is colorless. Under outdoor ultraviolet light or ultraviolet equipment, the product gradually changes from colorless to colorless due to absorption of ultraviolet light, and rapidly changes from colorless to colorless under non-ultraviolet return. This product has strong light change characteristics, large color difference changes, obvious features, printing features with any other ink and printing methods can not be copied, reliable anti-counterfeiting, the design presented by the effect is very good.
Second, technical parameters:
item | Parameter standard | item | Parameter standard |
Appearance: | Light purple fluid | Viscosity: (cps/25℃) | 2000±200 |
Adhesion: (3M tape) | 100/100 | Solid content: (weight loss method) | 50±2 |
Light change color (under UV light) : | Colorless tint/tint tint | Shelf life: | 12 months at room temperature |
Third, the use of technology:
1. Printing method: Screen printing: recommended 250-300 mesh screen printing; If the viscosity is high in the printing process, we can dilute it with DSK783.
2, drying method: infrared drying: at the temperature of 80℃-100℃ drying time is 30-50 seconds, air cooling time is 20-30 seconds.
When the temperature is 50℃-60℃, the drying time is 15-20 minutes. Air cooling time 10-15 minutes
3, laminating requirements: laminating temperature 130-150℃, hot laminating time 20-25 minutes, air cooling time 15-20 minutes laminating pressure does not exceed 11Mpa.
Iv. Precautions:
1, the printing effect is related to the substrate used, the working environment, laminating pressure/time/temperature/dryness and other factors. If the effect is different before and after using the same type of ink, please confirm that the above printing conditions are stable.
2, accidentally contact the product to the skin or splash into the eyes, please wash immediately with plenty of water, in serious cases, please seek medical attention in time;
