Abstract
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.
