Summary:PURPOSE:To easily check a conventional printing plate, etc., with a driving process by using plural light translucent original platen sheets on which a color identification mark and an aligning mark are printed. CONSTITUTION:The color identification marks 3 and 4 and the positioning marks 1, 3 and 5 are printed on the plural sheets with transparency such that a register mark can be seen through the back, or plural transparent films which are marked off in the shape of a lattice and whose register marks are readily aligned. After original platen sheets are correctly aligned through the use of register marks for a printing plate, they are bonded with a tape, etc. Three-color split originals with register marks are correctly aligned with the color identification marks 3 and 4 and the aligning marks 1, 3 and 5, all of which are printed on the original platen sheet. Consequently, a conventional printing plate, etc., can be checked easily with the driving process.
