Abstract
A method of controlling a system including a printhead for printing an image on at least one surface, wherein the at least one surface differs in shape from a nominal surface by a known tolerance, and wherein the printhead and the at least one surface move relative to each other along a predetermined print path comprising at least one swathe. Small dot patterns (referred to as 'pathfinders') are printed on a surface of the object in a preliminary printing pass, then the printed dot patterns are analyzed, for example with a machine vision system. The necessary corrections may then be calculated from this analysis and applied to a subsequent full printing pass.
