Abstract

A method for creating a printed image with sections on an object using at least two inkjet print heads, includes forming the image of first and second image sections, in a y direction at a fixed angle different than 0° and 180° relative to an object conveying direction, printing print dots of the first and second sections using first and second heads having first and second inkjet nozzles with the sections partially overlapping in a region and potentially forming a light or dark line, defining first and second complementary nozzle fields of the first and second heads to be active for each column of dots in the y direction, and placing a joint between the fields in the overlap region in a light or dark area of the column for each column of dots, avoiding potentially disruptive light or dark lines at the joint and keeping the image without defect.
