Abstract (en)
The image-setter is a hybrid drum type which combines the advantages of internal and external drum image-setters and which provides a solution for protecting the opto-mechanical devices from contamination by ink, fountain, processing and cleaning liquids, etc. The printing press comprises a hollow transparent cylinder 110 for carrying on its outer surface an imaging element 150. A radiation beam 161 is projected by deflecting means 160 located inside said hollow cylinder 110 through transparent cylinder wall 111 towards imaging element 150. After exposure and optional development a master is obtained. Ink applied onto the printing surface 151 of said master is then transferred to a substrate 170. The imaging element is preferably provided by coating a radiation sensitive composition onto the outer surface of said hollow transparent cylinder using coating means 140. <IMAGE>
