Abstract
A process is provided for a printing form for wet offset printing. A printing style is formed on an ink-transferring surface of the printing form ( ) by forming ink-absorbing and ink-repelling areas. For illustration, the ink-transferring surface is wetted with a moistening agent. The areas of the moistened surface that are to be made into ink-absorbing areas are dried in a specific manner, and a material that absorbs printing ink is uniformly applied to the ink-transferring surface with the still dry areas. It is also possible to uniformly apply to the ink-transferring surface first a flowable material that absorbs printing ink, to dry the areas to be made into ink-absorbing areas in a specific manner, and to remove it from the areas to be made into ink-repelling areas by means of moistening agent.
