摘要： Flexible and reusable lithographic printing tapes are prepared from a zirconia ceramic that is an alloy of ZrO.sub.2 and a second oxide chosen from MgO, CaO, Y.sub.2 O.sub.3, Sc.sub.2 O.sub.3, a rare earth oxide or a combination of any of these. These printing tapes have an average thickness of less than about 5 mm. In use, a surface of the zirconia alloy ceramic printing tape is imagewise exposed to electromagnetic radiation which transforms it from a lydrophilic to an oleophilic state or from an oleophilic to a hydrophilic state, thereby creating a lithographic printing surface which is hydrophilic in non-image areas and is oleophilic and thus capable of accepting printing ink in image areas. Such inked areas can then be used to transfer an image to a suitable substrate in lithographic printing. These printing tapes are directly laser-imageable as well as image erasable.
摘要翻译：柔性和可重复使用的平版印刷胶带是由氧化锆陶瓷制成的，氧化锆陶瓷是ZrO 2和选自MgO，CaO，Y 2 O 3，Sc 2 O 3，稀土氧化物或其任何组合的第二氧化物的合金。这些印刷带的平均厚度小于约5mm。在使用中，氧化锆合金陶瓷印刷带的表面成像地暴露于电磁辐射，其将其从亲液性转变为亲油性状态或从亲油性转变为亲水状态，由此产生在非图像中亲水的平版印刷表面并且是亲油的，因此能够在图像区域中接受印刷油墨。然后可以使用这样的油墨区域在平版印刷中将图像转印到合适的基底上。这些印刷胶带可直接进行可激光成像，以及图像可擦除。

摘要： The present invention provides a method for preparing an aluminium foil comprising the steps of roughening an aluminium foil and subsequently anodizing said aluminium foil characterized in that after said anodization said aluminium foil is cleaned using an aqueous bicarbonate containing solution. The present invention further provides a mono-sheet silver salt diffusion transfer material having as a support the alumium foil obtainable from the above defined method. The step of cleaning in the bicarbonate containing solution improves the adhesion of an image receiving layer containing physical development nuclei to the aluminum foil as revealed from the increased amount of silver precipitated in the image receiving layer when the aluminum foil provided with an image receiving layer is used in a diffusion transfer reversal (DTR) process.

摘要： A method for producing an erasable printing form by making the outer layer of the printing form from a material containing strong micro-dipoles, preferably a ferroelectric material, in particular a ferroelectric ceramic. In wet offset printing, the non-printing areas of the printing form are rendered hydrophilic by a hydrophilizing agent and they are maintained during the entire printing process. Plate cleaners can, for example, be used as the hydrophilizing agents. The printing form can be erased by a nonpolar solvent and can be reused again by rendering the non-printing areas hydrophilic again.

摘要： The invention relates to a liquid transfer article, such as a printing roll, having a laser-engraved coated surface comprised of wells adapted to receive a liquid and land areas adapted to be wiped free of any liquid prior to contacting a receiving surface so that only the liquid in the wells are transferred. The land areas of the coated surface have a density of greater than 95% theoretical and a roughness of less than 6 micro-inches R.sub.a to insure that any unwanted liquid on the land areas can be wiped clean prior to contacting a receiving surface. The invention also relates to a method for producing the liquid transfer article.

摘要： A lithographic printing plate that is transformable by spark-discharge techniques so as to change its affinity for ink. The plate features a layered structure including an ink-receptive substrate, a conductive layer and an ink-repellent coating. The ink-repellent coating contains a dispersion of image-support pigments that promote straight-line travel of the spark to the surface of the plate, thereby promoting accurate imaging.
