Abstract
Method for printing on a pharmaceutical tablet by etching a printing plate to form a pattern of etchings therein within an area corresponding to an outline of the tablet, varying the ink-retaining volumes of the etchings in a pre-determined manner and in a direction across the etching pattern from one side to an opposite side, placing ink into the etchings, and transferring ink from the etchings in the etched printing plate onto an outer surface of the tablet. Variations in the ink-retaining volumes of the etchings cause a larger amount of ink to be transferred from etchings having a larger ink-retaining volume than from etchings having a smaller ink-retaining volume during the ink transfer stage. This causes different changes in the color of the outer surface of the tablet dependent on the amount of ink being transferred.
