Treatment and design area factor measurement system null

摘要

PURPOSE:To achieve simplification and speeding up of a printing plate treating line in a printing system and to improve its productive efficiency by a method wherein the printing plate for which treatment of development or the like is ended is automatically conveyed to a pattern areal rate measuring device with a conveying apparatus and a pattern areal rate is measured. CONSTITUTION:A printing plate 21 which is developed and fixed with a developing device 14 is automatically conveyed from the developing device 14 to a pattern areal rate measuring device 15 with a conveying roller 26 and a suction belt 100A, and a pattern areal rate of the printing plate 21 is measured. At that time an identity mark 22 of the printing plate 21 is also simultaneously, read. The pattern areal rate of the printing plate 21 and the identity mark are made to form a pair, which is recorded to be stored in a memory 16 for each new printing plate 21. The memory 16 transmits a pattern areal rate measuring data of the printing plate 21 corresponding to the identity mark 22 designated with a controller 18 to the controller 18. The controller 18 receives a transmit data from the memory 16, and controls an ink feed amount regulator 24 of a printer 17 to perform printing by the printer.
