Abstract (en)
[origin: WO2020007791A1] The invention relates to a method for operating printing press (01), wherein a test printed image (566) is produced on a substrate (02) by means of a print head (416; 616; 816) which has a multiplicity of dot-generating devices (583) which are arranged in the form of a generator matrix (578) consisting of generator rows (579) and generator columns (581), which test printed image (566) has a function testing region (564), for the production of which a multiplicity of function test elements (572) which are arranged in the form of a test matrix (574) consisting of test rows (576) and test columns (577) are generated by means of the dot-generating devices (583), and wherein the test rows (576) are arranged such that they are oriented parallel to a transverse direction (A), and wherein it is true for a plurality of function test elements (572) within the test matrix (574) that function test elements (572) which are closest neighbours in pairs in relation to the transverse direction (A) are not closest neighbours in relation to absolute spacings within the test matrix (574); and to a printed product.
