摘要： A method for correcting mistakes and other imperfections in printing members is disclosed. Ink accepting areas of the printing member are rendered non-ink accepting by treatment with a deletion fluid. Deletion fluids include, for example, acids, alkalis, and oxidizing formulations. A preferred deletion fluid is concentrated sulfuric acid.
摘要翻译：公开了一种用于校正印刷部件中的错误和其它缺陷的方法。通过用缺失液处理使印刷部件的油墨接受区域变得不油墨。缺失液包括例如酸，碱和氧化制剂。优选的缺失液是浓硫酸。

摘要： A method for preparing a substrate for a planographic printing member is disclosed. A liquid that contains water; a soluble alkali metal silicate, preferably sodium silicate; and a dispersed particulate material is coated on a support, to produce a hydrophilic layer on the support. A layer of image material may be coated over the hydrophilic layer to produce a planographic printing member. In one embodiment the liquid contains a mixture of two particulate materials, preferably alumina and titanium dioxide. The substrate has a surface roughness of about 0.1 &mgr;m to 2 &mgr;m. The substrate is suitable for preparing a planographic printing member processable to a resolution of 10 &mgr;m or less and in which the dots having a roundness of less than 2 are formed.
摘要翻译：公开了一种用于制备平版印刷部件用基板的方法。含有水的液体可溶性碱金属硅酸盐，优选硅酸钠; 并且将分散的颗粒材料涂覆在载体上，以在载体上产生亲水层。一层图像材料可以涂覆在亲水层上以产生平版印刷构件。在一个实施方案中，液体包含两种颗粒材料的混合物，优选氧化铝和二氧化钛。基材的表面粗糙度为约0.1〜2μm。该基材适于制备可加工成10μm或更小分辨率的平版印刷部件，其中形成圆度小于2的点。

摘要： A method for forming a planographic printing member is disclosed. A hydrophilic layer is formed on a support by contacting the support with a silicate solution that contains a silicate and a particulate material. An image layer is provided over the hydrophilic layer. The hydrophilic layer is treated to ensure that the image layer is able to change color on exposure. The hydrophilic layer may be treated with an acid, with a buffer formulation, with a colloidal suspension, or with a salt. Preferably the hydrophilic layer is treated with aluminum sulphate.
摘要翻译：公开了一种用于形成平版印刷构件的方法。通过使载体与含有硅酸盐和颗粒材料的硅酸盐溶液接触，在载体上形成亲水层。在亲水层上方设有图像层。处理亲水层以确保图像层能够在曝光时改变颜色。亲水层可以用酸，缓冲剂配方，胶态悬浮液或盐处理。优选地，用硫酸铝处理亲水层。
