In recent years, the field of Computer-To-Plate (CTP) system has been remarkably developed. Some photopolymer type offset-printing plates for CTP system have been presented, The sensitivity of these plates is the order of 100μJ/cm2 for visible laser light such as Ar+ laser (488nm). Photoinitiator is the most important material in the composition of photopolymerization type printing plate. This paper describes the recent progress of the Ar+ laser sensitive initiator system for radical polymerization. He-Ne laser and near infrared laser sensitive photoinitiator system are also discussed.
