Abstract

Method for reducing banding effects in images, in particular gloss banding effects, by means of a printing module, a hardening unit and a medium feeder, wherein the printing module provides printed lines with a line width B in a print scan direction, whose ends forming the line margin define a printing texture, and wherein the hardening unit provides essentially completely hardened lines with a line width H, whose ends forming the line margin define a wet/dry texture, wherein a printed line of a printing scan partially, but not fully, overlaps with the hardened line of a hardening scan, in a print scan direction.
