Zusammenfassung:In order to manufacture a pair of main plates closely contacted with both the faces of a member to be exposed to light, patterns are drawn on a pair of original dry plates by a main pattern drawing device and developed. Thereafter, the developed pattern formed on one of the pair of original dry plates is successively transcribed even times in such a manner that a transcribed pattern having just formed on a newly supplied dry plate at a prior transcription is now transcribed to a fleshly supplied dry plate at a next transcription, and the developed pattern formed on the other one of the pair of original dry plate is successively transcribed odd times in such a manner that a transcribed pattern having just formed on a newly supplied dry plate at a prior transcription is now transcribed to a fleshly supplied dry plate at a next transcription, thereby forming a pair of main plates.
