3. Dirty: Many ink stains appear in the non-graphic area of ​​the fingerprints.

4. Paste plate: Ink that is too thick and too sticky causes paper particles, ink skin and other particulate impurities to concentrate on the dots of the printing plate on the printing machine, making the printed product blurred.
