Abstract
A method for treating a re-imageable printing form includes surface modifying a surface of the printing form acting as a printing area in a nanoscopic range by chemically functionalizing the surface through covering with molecules, in particular amphiphilic molecules or polymers. The printing form is subjected to a primary process of imaging by laser radiation, and subjected to a primary process of application of at least one lithographic fluid, for example dampening solution, printing ink and/or varnish. The molecules are fixed in image regions by the primary process of imaging. The molecules are removed in non-image regions substantially by at least one primary process different than the application of printing ink, in particular by imaging, application of dampening solution or chemical developing. An apparatus for treating a re-imageable printing form, a machine for processing printing material and a method for treating a surface contacting printing material, are also provided.
