Protective Coatings

DLC & PVD coatings for the printing industry

Problem

In the printing industry, rollers, bearings, guides and system components are under constant mechanical and chemical stress. Abrasion, friction and material adhesion are caused by continuous contact with paper, paints and coating materials and impair the surface quality and functionality of the components in the long term. In addition, there is a high level of chemical stress caused by printing inks, solvents and cleaning agents, which can attack the surfaces and lead to corrosion or material fatigue. Particularly critical are adhering microparticles that settle on rollers or guides and enter the printing process. They cause printing errors, uneven color distribution and quality deviations, which leads to rejects, rework and production interruptions. This increases maintenance costs and downtimes, while process reliability and print quality are significantly reduced.

Solution

With its laser-based PVD coating technology, ANTACON offers an effective solution for the high demands of the printing industry. The extremely smooth and wear-resistant DLC coating permanently protects smooth and structured roller surfaces, as well as bearings, guides and other system components, against friction, abrasion and material adhesion. Their close contour reproduction ensures a uniform coating quality and optimum surface function. The non-stick effect prevents ink and coating residues from sticking, while the high resistance to chemicals and solvents enables easy cleaning and a long service life. The result: stable processes, consistent print quality and lower maintenance costs over the entire production cycle.
