AbstractA 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. | InventorsApplicationNo. 05/696765 filed on 06/16/1976US Classes:101/463.1, Lithographic plate making, and processes of making or using copy elements, and elements per se101/163, Bed and platen101/170, Processes101/401.1, Blanks and processes101/41, Bed and platen101/492, Transfer or offset101/493Resilient surfaceField of Search101/41, Bed and platen101/44, Feeding or delivering101/401.1, Blanks and processes101/170, Processes101/163, Bed and platen101/150, INTAGLIO101/35SPECIAL ARTICLE MACHINESExaminersPrimary: Crowder, Clifford D.US Patent References1217250, 2166138, 2202464, 2748696, 2842046, 3701317International ClassB41F 17/00 (20060101) |
