Abstract
Systems and methods for high-speed variable printing are provided. Ink jet technology and lithographic systems may be combined in such a way to create a fully variable and high-quality print system. Ink is applied to a printing cylinder. An aqueous solution is then applied on top of the ink to produce a negative image. A positive image is then transferred in ink to a print medium. The systems and methods described herein may be used to create high-quality one-to-one marketing applications.
Claims17
A method of printing comprising the steps of:
- providing a printing plate on a printing cylinder, the printing plate having an image area which accepts ink and a non-image area which does not accept ink thereon;
- coating the printing plate on said cylinder with ink, so as to cover the image area of the printing plate;
- applying an aqueous solution with an ink jet nozzle in a pattern on top of selected portions of the ink in said image area;
- and
- transferring the ink from the printing plate on the printing cylinder to a substrate to form an image, such that the ink is transferred from said image area of the printing plate which is not covered by the aqueous solution.
