waterless offset lithography
waterless offset lithography[¦wȯd·ər‚les ‚ȯf‚set li′thäg·rə·fē]
A method of printing in which the nonimage area of the plate is coated with silicone to repel the ink (in contrast to water in traditional lithographic printing) and the image is printed from ink that adheres to the image in the metal base. In practice, the image from a plate is offset onto the rubber blanket of an impression cylinder, and transferred to a sheet of paper. Also known as dryography.
