Abstract

A technique for producing a pre-distorted design format on a printing plate for use in a print transfer system in which an inked design engraved on the plate is picked up by a soft transfer pad and applied to the irregular surface of an article to be decorated, the pad being forced against the surface and conforming thereto to impress the inked design thereon. In this technique, a physical master is created which is an exact replica of the article to be imprinted, the irregular surface of the master being engraved or otherwise prepared to accept ink to define the design which is to appear on the article. The design on the master is inked, and this inked design is picked up by the transfer pad and applied to the regular surface of a proof sheet, whereby the distortion in the design impressed on the proof sheet reflects the distortion introduced by transferring from the irregular to the regular surface. The desin appearing on the proof sheet is engraved on the printing plate to provide a pre-distorted format thereon which, when inked and transferred to the irregular surface of the article, produces an undistorted imprint thereon.
