    Abstract: It is especially described a control process for intaglio printing, in particular for printing paper securities, such as banknotes. This control process includes defining on an intaglio printing plate (80) control areas (150, 151-155; 170, 171-179) designed in such a manner as to allow in particular evaluation of effects of the printing pressure applied during printing of a substrate by means of the intaglio printing plate (80) and evaluation of effects of the ink coverage applied during inking of the intaglio printing plate (80), which control areas (150, 151-155; 170, 171-179) are engraved in a portion of the intaglio printing plate (80) in order to produce corresponding printed control zones (160, 161-165) on the substrate. The process further includes carrying out of measurements in the printed control zones allowing evaluation of the printing pressure applied during printing of the substrate as well as of the ink coverage applied during inking of the intaglio printing plate (80).
