Causes
- No good static charge in the substrate direction
- No good ESA effect of the cover stock
- Poor paper or ink quality
Effects
- Missing dots in printout
- Open printout
- Lack of brilliance
Modern machines in illustration, decor and packaging printing are becoming faster and faster, while at the same time the demand for print image resolution is increasing and substrate quality is decreasing.
This stands in the way of sufficient emptying of the cells and leads to poor printing results.
By means of electrostatic charging, the ink in the cell is oriented towards the substrate. This leads to quantitatively better cell emptying and thus to higher print quality.
