Although other cleaning techniques currently exist for anilox roller cleaning, they are archaic and don’t come without their challenges.
Laser cleaning is slowly becoming the future of anilox roller cleaning . Chemical or abrasive blasting systems used to remove the chemicals found in modern day inks and adhesives tend to clog anilox roll cells. This is also a very time consuming and messy task with disposal and constant consumable issues.
The teflon & polyeurethane materials attached to a roll’s surface form a hydrophobic film; which causes the ink to bead up, much like water does on a newly waxed car. The only way to remove these contaminants completely (along with other organics) is to thermally decompose them with the use of laser light.
Chemical cleaning unfortunately leaves a film on these “cleaned” rolls (as do all grit blasting methods) – only laser cleaning can truly restore the surface!
