The gel method of printing variable information of the present invention involves applying inks onto a substrate that is part of or attached to a cylinder of the printing machine. Imaging is by means of an energy source in the UV, visible or infrared regions, modulated to represent a digital image pattern that has been composed on a computer. The consequence of imaging is to gel the ink and increase its adhesion to the substrate of the printing cylinder. The non-gelled background ink with lower adhesion is then removed by a squeegee action and returned to an ink reservoir. The remaining image is transferred to an offset blanket or directly to print stock by pressure. The process does not use a master, but produces an image that is erased after printing with each cylinder rotation so that the next rotation producing the next print can have fresh information written upon it.

A color image is digitally printed onto an intermediate transfer medium. The image is subsequently transferred from the intermediate transfer medium to a final substrate, which may be a cellulosic textile, such as cotton. Bonding of the color images is provided by the reaction between compounds selected from each of two chemical groups contained in the intermediate transfer medium. The first groups comprises compounds with functional groups capable of reacting with active hydrogen, such as isocyanate or epoxy groups. The second group comprises compounds with functional groups containing active hydrogen, or compounds with functional groups containing active hydrogen after a conversion process. The functional groups of one or both reactive chemical groups may be protected either by blocking with internal or external blocking agents or by a physical barrier such as encapsulating agents. The blocking agents are removed by the application of energy, such as heat, during the transfer of the image from the intermediate transfer medium to the final substrate. The intermediate transfer medium may be comprised of additional components which may be combined with either or both of the above two chemical groups, or applied as separate layers. Examples of such components are a thermally expandable material, an exothermic chemical, a release agent, and / or absorbent material. Transferred images so produced have a soft hand, particularly when applied to a textile, and excellent fade and abrasion resistance.
