The invention relates to producing a relief image on a metal base. The present method includes forming a resist pattern on a surface of a base and etching the sections of the metal which are not covered by the resist. In the present method, copper or an alloy thereof is deposited as a resist on a metal base having an electrode potential that is more negative than the electrode potential of copper, and etching is carried out in a solution that dissolves the parts not covered by the resist primarily as a result of a contact exchange reaction between the metal of the base and the copper ions. The invention makes it possible to improve the quality of the resulting image by means of reducing etchback of a metal base via pores of a resist, and to reduce the cost of producing products.

This application provides an alignment film transfer printing plate including a substrate, a first dot arranged on the substrate, and a plurality of second dots arranged around the first dot. A height of each of the second dots in a direction perpendicular to a surface of the substrate is less than or equal to a height of the first dot in the direction perpendicular to the surface of the substrate, a blocking portion is formed on an end of the first dot away from the substrate, and an area of an end surface of each of the second dots away from the substrate is less than an area of an end surface of the blocking portion away from the substrate.

The present invention relates to a gravure printing process for the production of a virtual three-dimensional pattern in a coating comprising flake-form effect pigments on a print substrate, to a coating produced in this way, and to the use thereof.

A printing plate for gravure printing includes a gravure roll with a cylindrical shape, and printing portions corresponding to a graphic pattern to be printed is provided on an outer circumferential surface thereof. Each of the printing portions includes first banks extending in a substantially parallel direction to a rotation direction, second banks extending in a direction substantially orthogonal to the rotation direction and in each of which at least one end portion is connected to the first banks, and cells defined by the first banks and the second banks, and in the cell located at a print starting end portion of each of the printing portions which first comes into contact with a printing object in the rotation direction, a partition bank which divides the cell in a diagonal direction is provided.

A gravure printing plate includes a convex portion and two or more polygonal cells partitioned by the convex portion, and including at least one protruding portion disposed at an edge of each of the at least two polygonal cells and extending toward a central portion of the corresponding cell therefrom.

An article with an operative liquid-bearing surface is adapted for transferring that liquid to a substrate material or printing plate. The entire operative surface of the article is provided with a pattern of microscopic discrete depressions which are usually laser-engraved into the surface so that a substantially continuous wall structure remains which surrounds and defines the depressions. In particular the depressions are of a cross-sectional shape which is symmetrical about one or both of a lateral and a medial axis perpendicular thereto, and arranged adjacent one another in offset fashion, and above and below one another so that the pattern thus formed is substantially uniform and repeating. Each of at least one of the pairs of lateral or medial sidewalls of any one depression are contoured, the contour of one of the pair being generally the mirror image of the other.
