Patent ID: 7974554

Claim:
A method for printing of a recording medium, comprising: generating potential images of images to be printed on a potential image carrier; to develop the potential images, using a liquid developer that comprises a transparent photo-polymerizable carrier liquid and charged colorant particles suspended therein; transporting the developer via an applicator roller to the potential image carrier in a quantity that is substantially constant per time and area to form a developer film in a developing zone between the potential image carrier and the applicator roller for development of the images, the developer film adjacent to the potential image carrier comprising said photo-polymerizable carrier liquid enriched with said colorant particles in regions in which potential images are present on the potential image carrier and comprising said photo-polymerizable liquid substantially depleted of said colorant particles in regions in which no potential images are present, the developer film splitting at an end of the developing zone into an image film adhering to the potential image carrier comprising the developed potential images and a film adhering to the applicator roller comprising said photo-polymerizable liquid with residual colorant particles; transferring a portion of the image film with the developed potential images from the potential image carrier onto the recording medium such that the colorant particles and a portion of the photo-polymerizable liquid in which the colorant particles are arranged migrates from the image film; and fixing on the recording medium with a UV radiation a first part of the portion of the image film with the potential images to be developed such that the colorant particles of the developed potential images are embedded in a solid, transparent polymer mass via photo-polymerization, and otherwise the photo-polymerizable liquid in a second part of the portion of the image film without the potential images is solidified into a transparent film.
