ORIGINAL PLATE MATERIAL SHEET, METHOD FOR MAKING ORIGINAL PLATE USING SAID SHEET, AND METHOD AND DEVICE FOR EXECUTING PRINTING USING SAID DEVICE AND SAID ORIGINAL PLATE

摘要

PURPOSE:To eliminate a part of a light-reflecting film conductive layer abutted by an electrically conducting member to rapidly and sharply print hand-written characters and drawings, etc., on a large number of bodies to be recorded in a simple manner, by applying a predetermined electric potential difference between the electrically conducting member and return electrode. CONSTITUTION:An original plate material sheet 1 consists of a transparent resin base layer 1a and a light-reflecting film conductive layer 1b vapor-deposited on one surface of the base layer 1a. An electrically conducting member 2 is traveled on the light-reflecting film conductive layer 1b under being abutted thereto to write an arbitrary character, etc. At this time, a predetermined potential difference between the electrically conducting member 2 and a return electrode 3 is applied from a power source 4, whereby an electric current conduction action is generated to eliminate a part of the light-reflecting film conductive layer 1b abutted by the conducting member 2. This cut out part 1b1 forms an image part 6 of an arbitrary character, etc., on the light-reflecting film conductive layer 1b. In this manner, am original plate 7 is simply and easily made from the original plate material sheet 1. Ink corresponding to the image part 6 is melted by a light-heat conversion to be transferred to a body to be recorded 10.
