Abstract
The present invention is a driograhic imaging method which employs an ink comprised of an organic material which is convertible from a state of high viscosity to a state of low viscosity by exposure to high energy radiation. The ink is applied to an inking roller in its initial state of high viscosity and exposed to activating radiation in an imagewise manner to convert the material to a state of low viscosity and thereby reduce the viscosity of the ink in a configuration corresponding to the pattern of radiation. Contacting the irradiated inking roller with a receiving member results in transfer of the ink in imagewise configuration from the inking roller to the receiving member.
