GRAVURE PRINTING ROLL
A gravure printing roll that enables printing of fine dots with a size close to that of cells and enables printing on a print subject, such as a printing substrate, without changing the appearance of the print subject. The gravure printing roll includes: a gravure printing roll body; and cells formed in a peripheral surface of the gravure printing roll body. Each of the cells has an opening with a ratio between a dimension in a circumferential direction of the gravure printing roll body and a dimension in an axial center direction of the gravure printing roll body (dimension in the circumferential direction/dimension in the axial center direction) being 1.15 to 7, and have an opening area of 3900 m.sup.2 or smaller.
Image-providing printing forme, and method for producing a printing forme
An imaging printing form having a base body with an elastomeric coating, in which the elastomeric coating carries an engraving pattern. The elastomeric coating has a hard rubber with a hardness of greater than 40 Shore D, and more particularly greater than 70 Shore D. The hard rubber is based on butadiene-acrylonitrile rubber (NBR), carboxyl group-containing nitrile rubber (XNBR), hydrogenated acrylonitrile butadiene Rubber (HNBR) or combinations thereof.
