Method For Imprinting A Recording Medium

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 film adhering to the potential image carrier comprising the developed potential image and a film adhering to the applicator roller comprising said photo-polymerizable liquid with residual colorant particles;
• transferring 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 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 is solidified into a transparent film.

An electrographic printer or copier device, comprising:

• an imaging station at which potential images of images to be printed are generated on a potential image carrier;
• a developer station at which to develop the potential images, a liquid developer is used that comprises a transparent photo-polymerizable carrier liquid in charged colorant particles suspended therein;
• an applicator roller which transports the developer 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 potential 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 image and a film adhering to the applicator roller, said film comprising said photo-polymerizable liquid with residual colorant particles;
• a transfer station at which the image film with the developed potential images is transferred 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
• a fixing station where the image film with the potential images to be developed is fixed on the recording medium with a UV radiation 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 is solidified into a transparent film.
