Ink spray point phenomenon description: the phenomenon of irregular small dots on the edge of printing pattern after ink printing.
Causes of spray point phenomenon
1. The viscosity of ink is too high when printing.
2. Poor ink formula design belongs to high viscosity ink.
3. The printing speed is too slow.
4. Ink volatilization speed is too fast.
Countermeasures for spray point phenomenon
1. Low viscosity printing is adopted when printing ink (less than 15 seconds).
2. Improve the ink formula, increase the fluidity of ink.
3. The slower the printing speed is, the easier it will happen. Therefore, the use of low viscosity and high speed can be improved.
4. The viscosity of the ink increases with the drying speed of the ink film, so the use of slow drying solvent in the minimal image part can be improved.
