<p>In a method for operating an ink jet printer with a curved platen the firing of the ink nozzles of the print head is controlled in a specific way to avoid the effects of misplacement of ink dots on the printing medium due to the curvature of the platen and other effects. The printing of markings on the printing medium is performed in several passes of the print head whereby the medium is advanced between passes. During a pass, central nozzles are fired more often than nozzles at the periphery of the print head because the precision for peripheral nozzles is worse than for central nozzles. Printing during a single pass is thus performed in bands (50a-50d) whereby the amount of ink placed in central bands (50b, 50c) is higher than in peripheral bands (50a,50d). <IMAGE></p> |
