    • 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.
    • 用于处理成像的印刷形式,特别是用两亲分子覆盖的印刷形式或与聚合物(例如糖)一起处理的方法包括将胶状物,特别是微胶囊层涂覆在液体状态的印刷形式的表面上。 相对于直到将平版印刷液体(例如润版剂或印刷油墨)施加到表面的时间间隔,在短暂或可忽略的时间间隔之后,将胶状物除去或还原成剩余的纳米镜片覆盖物。 胶的去除或还原优选以静止液体状态进行,即在施用的胶干燥之前,优选在施用后立即进行。 剩余的胶覆盖物保护印刷形式免受污染物并增加其亲水/疏水对比。 还提供了一种用于处理成像的打印形式的装置,可再成像的打印形式和用于处理打印材料的机器。
