Method for producing a structured surface contacting printing material, structured surface, machine and method for self-repair of structured surfaces

摘要

A method for producing a structured surface making contact with printing material, preferably a cylinder cover, includes producing a structured coating having microparticles on a substrate, preferably a stainless steel plate. The microparticles are encased antiadhesively and agglomerated by adsorption of nanoparticles, and the agglomerates being produced are fixed in a sol-gel matrix. A surface produced in this way has a structured coating on a substrate and the coating has microparticles. The coating has agglomerates fixed in a sol-gel matrix and including microparticles encased antiadhesively by adsorption of nanoparticles and preferably formed of silicon carbide. The surfaces advantageously have a self-repair function since, in the case of abrasion of structural elevations, the antiadhesive casings of the microparticles are exposed and the antiadhesive property of the coating is maintained.
