Abstract
844,696. Printing surfaces. DITTO Inc. Nov. 21, 1956 [Nov. 21, 1955], No. 14012/59. Divided out of 844,695. Class 100(2) A method of preparing a duplicating master printing sheet comprises forming as assembly of sheets by placing a stencil imaged sheet 1 in contact with a second sheet 11 which in turn is placed in contact with a fusible layer 4 on a carbon or like transfer sheet 3, exposing the surface of the imaged sheet to infra-red radiation to transfer composition corresponding to the image to the sheet 11. The method is applicable to the production of master sheets for use in spirit duplicating processes, hectographic processes, and planographic or lithographic processes, the coating on the transfer sheet being chosen in accordance with the process for which the master to be prepared is to be used. As shown the stencil sheet 1 with the imaged side facing outwards is clamped together with the sheet 11 and the transfer sheet 3 having a coating 4, on a cylinder 6 and rotated past a slot 9 in a member 8 beneath which is an infra-red source 10. The source 10 preferably has an intensity of 1350 watts and is placed 1/16 inch from the surface of the copy sheet. The rotation of the cylinder is such that the exposure time is 1/10 second. On removing the transfer sheet from the sheet 11 the back of the sheet 11 has imaged portions which correspond to and are a mirrorimage of the original image on the front of the copy. The back of the sheet 11 may thus be used as a master sheet for direct printing as in a spirit duplicating process. When the master is to be used in gelatin processes a direct reading image may be obtained by placing the stencil sheet 1 face downwards on the transfer sheet.
