Aluminum CTP plate printing technology began in the 1970s and achieved industrialization in the 1990s. At present, it has entered a stage of mature technology, stable quality and widespread application.Aluminum CTP plate printing system mainly includes computer system, imaging system and version supplying system.In Aluminum CTP plate printing, the layout information of the publication is directly output to the printing plate. Compared with traditional offset printing, the output of film and photocopying of PS plate are reduced. The printing process mainly includes the output of digital sample printing, CTP platemaking and printing.Among them, Aluminum CTP plate printing is composed of digital pre-press processing system, raster image processing system, phototypesetter, developer and plate;Aluminum CTP plate printing are divided into four types: silver halide diffusion type, photosensitive resin type, mixed type and thermal type.Direct platemaking equipment is divided into internal drum type, external drum type and desktop 3 types.Aluminum CTP plate printing also requires the use of a traditional plate, which is installed on the plate cylinder of a printing machine, and then scanned for imaging to complete the plate-making operation, so it is not really digital printing.
