摘要： A print substrate-contacting element having an ink-repellent coating on a surface of a microstructured carrier is described, the coating including at least one derivative of an amphiphilic organic compound whose polar region has an acidic character. A method for coating a surface of a microstructured carrier of a print substrate-contacting element is distinguished by the application of an amount of substance, which includes at least one derivative of an amphiphilic organic compound whose polar region has an acidic character, by treating the surface with an alcoholic solution of the amount of substance. The print substrate-contacting element can very advantageously be the surface of a back-pressure cylinder in a print substrate-processing machine, in particular in a printing press. The coating method can be carried out in a print substrate-processing machine.

摘要： Presented is a reusable printing form including a printing area that has a metal oxide surface, in particular a native oxidized titanium surface, which is treated with at least one amphiphilic organic compound whose polar region has an acidic character. In an advantageous embodiment, n-heptadecanyl hydroxamic acid {CH3-(CH2)16-C(O)—NH—OH} and/or n-octadecanyl phosphonic acid {CH3-(CH2)17-P(O)—(OH)2} is used. Also described is a method for imaging a reusable printing form. The reusable printing form can be used for offset printing.

摘要： A reusable printing plate, in particular for use both in wet offset printing and in dry offset printing, includes a printing area and a metal oxide surface treated with at least one fluorinated phosphonic acid. A printing press and a printing unit having the printing plate, a process for imaging the printing plate and a process for preparation of a fluorinated organic phosphonic acid are also provided.
