The flat surface of the plate or stone is slightly roughened, or etched, and divided into hydrophilic (= water-loving) regions that accept a film of water and repel the greasy ink, and hydrophobic regions which repel water and accept ink. The image may be printed directly from the stone or plate (in which case it is reversed from the original image) or may be offset by transfer to a flexible sheet, usually rubber, for transfer to the printed article.
