摘要： A process for treating an imaged printing form, in particular a printing form covered with amphiphilic molecules or with polymers, such as saccharides, includes applying a gum, in particular a microscopic gum layer, to the surface of the printing form in the liquid state. The gum is removed or reduced down to a remaining nanoscopic covering after a short or negligible time interval, relative to the time interval until the application of lithographic liquid, for example dampening solution or printing ink, to the surface. The removal or reduction of the gum is preferably carried out in the still liquid state, i.e. before the applied gum dries on, and preferably immediately after the application. The remaining gum covering protects the printing form against contaminants and increases its hydrophily/hydrophoby contrast. An apparatus for treating an imaged printing form, a re-imageable printing form and a machine for processing printing material, are also provided.

摘要： 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.

摘要： In a method for imaging a lithographic printing form, subareas of a surface of the lithographic printing form which are covered by amphiphilic molecules, are exposed to electromagnetic radiation. Following the exposure and before printing from the lithographic printing form, the subareas are treated with at least one complex-forming substance, so that a lithographic printing area structured into hydrophilic and hydrophobic regions is obtained.

摘要： A reusable printing form is treated after printing. The printing form has a substrate provided with amphiphilic molecules and it is cleaned to remove printing ink and provided with amphiphilic molecules, for fresh printing in the course of a reimaging process. Here, the printing form is provided with amphiphilic molecules in the course of the reimaging process substantially before cleaning to remove the printing ink.
