Zecher, manufacturer of anilox rollers, has installed a laser cleaning system from LaserEcoclean at its factory in the German town of Paderborn.
The laser cleaning system gently eliminates all ink and varnish residues. Jörg Rohde, head of applications technology at Zecher GmbH, said, ‘Microscopic imaging reveals that the inner recesses of the cells on cleaned rollers are barely distinguishable from those of a brand-new roller. After the cleaning process, the pick-up volume of the anilox roller can once again be used to its full extent, and printers benefit from the same uniform inking performance as before.’
The company is also confident that the surface of the roller remains wholly unharmed by the cleaning process. ‘As a relatively low-power laser beam is used, the temperature of the ceramic surface is well below the material’s melting point, which prevents any damage to the outside of the anilox roller,’ Mr Rohde concluded.
