Abstract

PURPOSE:To automate and rationalize the process of printing by recording on a magnetic card and printing out pattern information obtained by scanning a printing plate for offset printing by a device which has photoelectric converting elements, and by using it as data for the process of printing. CONSTITUTION:A printing plate 20 for offset printing is scanned by a photoelectric detector 10 consisting of photosensors 13. A printer number, etc., is inputted on a keyboard 47 to set plate size, the number of an ink adjustment key, an interval, the size of a printing effective area, etc., stored in an RAM46 and an ROM45. The output 41 of the photosensor 13 is selected by a multiplexer 42 and then converted by an A/D converter 43 into a digital signal, which is stored in the register of a CPU by way of an input-output control circuit 49 and a bus to be transferred to the RAM 46 by one ink adjustment key at every time together with a calibration mark 23 and data of the quantity of light from a light source, so that the information is recorded on a magnetic card or printed out after the entire plate surface is completed. Thus, the process of printing is controlled to automate and rationalize the printing, thereby preventing the production defective.
