摘要： A printing plate is described in which a plurality of relief areas are provided which stand proud of a floor of the plate, each of said relief areas having an uppermost surface to which, in use, is applied a liquid which is borne by said uppermost surface and subsequently contactingly transferred to a substrate material. Substantially the entire uppermost surface of one or more of said relief areas is provided with a predetermined pattern of depressions which define a corresponding pattern of islands within said uppermost surface. The invention is characterised in that the depressions within the uppermost surface comprise at least primary depressions of a first size and substantially geometric first cross-sectional shape, and secondary depressions, being of smaller cross-sectional area than said primary depressions and having a second cross-sectional shape which is distinctly more elongate than said first cross-sectional shape. The invention is further characterised in that the primary depressions are arranged substantially diagonally with respect to one another and in substantially continuous rows having a lateral separation which is at least three times a lateral dimension of the first cross-sectional shape, said secondary depressions also being arranged substantially diagonally with respect to one another and in rows, but the rows of the secondary depressions are orientated at a different diagonal angle to those of the primary depressions and are discrete in that their terminal depressions lie within consecutive rows of the primary depressions so as to define a corresponding pattern of islands of different sizes and diagonal orientations.
摘要翻译：描述了一种印刷版，其中提供了多个凸版区域，该凸版区域以所述版材的地板为基础，每个所述凸版区域具有在使用时被施加到其上的最上表面液体，该液体由所述最上面的表面承载并随后接触转移到基底材料上。一个或多个所述凹凸区域的基本上整个最上表面设置有预定图案的凹陷，所述凹陷在所述最上表面内限定岛的对应图案。本发明的特征在于，最上表面中的凹陷包括至少具有第一尺寸和基本上几何形状的第一横截面形状的主凹陷，以及次凹陷，其具有比所述主凹陷更小的横截面积，并具有第二交叉 - 明显比所述第一横截面形状更细长的截面形状。本发明的进一步特征在于，主要凹陷相对于彼此基本上对角地布置，并且基本连续的行具有至少为第一横截面形状的横向尺寸的三倍的横向间隔，所述第二凹陷也是基本上相对于彼此并且成行地对角地布置，但是次级凹陷的行以与主要凹陷的对角线不同的对角线定向，并且是离散的，因为它们的末端凹陷位于主要凹陷的连续行内，因此以定义不同大小和对角线方向的相应岛屿模式。
