A method for producing printing forms by way of irregularly-distributed printing points provides that an image original be opto-electrically scanned across individual surface elements with a desired detail resolution. A gray scale corresponding to the scanning signal is assigned to each surface element and surface elements of the same or approximately the same gradation are combined into sub-surfaces and the individual sub-surfaces are reproduced in accordance with their gradation value by way of a plurality of statistically-distributed printing points whose overall surface coverage within the sub-surface corresponds to the gradation of the sub-surface, whereby the combination of the sub-surfaces is undertaken in accordance with the actual boundaries of the same or approximately the same gradation within the original image.
