Abstract
The invention relates to a method for adjusting a gap in a printing system in which a first roller and a second roller are provided, wherein at least one of said first roller and said second roller comprises a seam, said seam corresponding to a variation of the diameter of said first roller and said second roller, respectively, along a circumference thereof. An interaction zone is provided, wherein said second roller is in rolling contact with said first roller under pressure, said interaction zone defining a gap for inserting a media to be printed. A size of said gap is controlled by varying a relative position of said first roller and said second roller when said at least one seam passes through said interaction zone, and said gap is adjusted in accordance with a length of said media to be printed and/or in accordance with a length of an image to be printed.
