3. diluent ratio
Name | ethyl ester | n-propyl ester | Buttonyl | PMA |
quick dry | 70 | 30 | ||
Medium stem | 30 | 60 | 10 | |
Slow dry | 65 | 30 | 5 |
4. printing viscosity
- Color ink: 14~18 "(ZAHN CUP 3#)
- White ink: 12~15 "(ZAHN CUP 3#)
Printing viscosity should be determined according to printing conditions
5. considerations
- Ink should be fully stirred before use;
- When the speed of the deep machine is slow, the ink viscosity should be increased for printing;
- Reduce the ink concentration, please use the dilute agent;
- When printing with this ink, it is recommended to scratch the sample to confirm the adhesion fastness of the ink to the printed film.
