ABSTRACT:
The present invention provides a digital offset printing method for producing a composite image on a substrate wherein the image is made up of a first plurality number of component images, each being formed from a different ink. The method comprises providing a first component image on a first surface, transferring the first component image from the first surface to an intermediate transfer module, repeating said provided and transferring steps for further component images until a second plurality number, less than the first plurality number, of component images has been accumulated on the intermediate transfer module, and transferring the accumulated component images from the intermediate transfer module to the substrate. The step of transferring the accumulated images from the intermediate transfer module to the substrate comprises applying a plurality of inks, which correspond to the second plurality number of accumulated component images, to the substrate, and repeating said steps until all of the first plurality number of component images have been transferred to the substrate.
