摘要： A method is disclosed for making on a transparent receiver material a continuous tone image, e.g. for medical diagnostic purposes, with an obtainable maximal transmission density in the visual region greater than 3.0, by means of ink jet. The method comprises ink-jetting combinations of at least one liquid black pigmented ink and at least one liquid grey ink to a transparent receiver comprising an ink receiving layer, a transparent support and a backing layer, said ink receiving layer comprising a N-containing polymer, preferably gelatin, as binder, and being substantially free of particles having an average size larger than 1 &mgr;m. Preferably the transparent receiver exhibits a haze value between 10 and 20%, determined according to standard test ASTM D 1003, due to the presence of a spacing agent in the backing layer.

摘要： A material is disclosed which is suitable for making a flexographic printing plate and comprises in the order given a base, a photopolymer layer, a barrier layer wherein the main component is a polymer different from gelatin, and an ink receiving layer wherein the main component is gelatin. An image having a high optical density can be printed on the ink receiving layer by image-wise jetting a water-based ink because the gelatin in the ink receiving layer has excellent ink receptivity and because the barrier layer reduces diffusion of monomers from the photopolymer layer to the ink receiving layer. The image present in or on the ink receiving layer can then be used as a photomask for the subsequent flood exposure of the photopolymer layer. After processing, a flexographic printing plate is obtained.
摘要翻译：公开了适用于制造柔性版印刷版的材料，其顺序包括基底，光聚合物层，阻隔层，其中主要成分是不同于明胶的聚合物，以及油墨接收层，其中主要成分是明胶。由于油墨接收层中的明胶具有优异的油墨接受性，并且由于阻挡层减少单体从光聚合物层的扩散，因此通过成像喷射水性油墨可以将高光密度的图像印刷在油墨接收层上到油墨接收层。存在于油墨接收层中或其上的图像然后可以用作光掩模，用于随后的光聚合物层的暴露。加工后，得到柔性版印刷版。
