Abstract
A printing method and apparatus is disclosed for printing an image on a printing medium by means of a printing head having a first number n of marking elements, the method includes printing the image as a set of N sub-images, N being a number C of colours used for printing multiplied by a number I of interlacing steps and multiplied by a number P of mutually interstitial printing steps (N=C*I*P), where the number I of interlacing steps is greater than 1. Each interlacing step generates an interlaced sub-image, a swath of an interlaced sub-image being printed during a printing pass. There is at least one linear relative movement between the printing medium and the printing head over a uniform transport distance TD in a slow scan direction between the printing of two subsequently printed interlaced sub-images. The transport distance TD is uniform for all linear relative movements and printing is carried out with a subset of the n marking elements, the subset of marking elements being changed after I printing passes.
