Abstract
A printing method for forming an image on a substrate by means of a printer containing a plurality of ink-filled chambers, which chambers each include a nozzle and which are operatively connected to a piezoelectric actuator, which includes the steps of image-wise energizing of the actuators to generate a pressure wave in each of the chambers so that ink drops are ejected from the nozzles of said chambers, and measuring the pressure wave in a chamber using a piezoelectric actuator operatively connected to said chamber, wherein the image for formation is analyzed with the use of an importance criterion for elements of said image, the image elements satisfying said criterion are determined, the chambers from which the ink drops should be ejected to form said image elements are determined, and the pressure wave in at least one of said chambers is measured during the formation of the image. The invention also relates to a printer adapted to the use of this method.
