Cigar Paper Boxes With Ribbon CTP direct platemaking machine and loading mode

Direct plate making system is a set of comprehensive multi-disciplinary technology industry, it includes precision machinery and optical technology, electronic technology, color digital image technology, computer and software technology, new plate and material technology, automation technology and network technology in one of the automatic production system, is another major technological revolution in the contemporary printing industry.

CTP direct plate-making machine mainly includes internal drum type, external drum type, platform type, curve type four categories, the most used is internal drum and external drum type, in these forms, the external drum type gradually shows the mainstream trend;

Major equipment supplier

CTP equipment suppliers are mostly from the United States, as well as German, Japanese companies established in the United States.

Manufacturers of large format equipment include Agfa, Barco, Creo, Heidelberg, Gerber, ECRM, Optronics, Seangel American Pre-Press Company, Japan Screen Company, etc. Small and medium format manufacturers are: PrintWare Company, DuPont Company and so on. There are Creo Company, Krause Company and others that provide equipment dedicated to newspapers.

Plate loading mode

According to the different degree of automation, loading can be divided into manual and automatic two kinds. Manual version of the machine is cheap, but generally required to operate in the dark room, so the efficiency is low; The automatic version of the equipment, high efficiency, but the price is more expensive, generally than manual models expensive about one hundred thousand dollars. Moreover, automatic devices must use a whole box of plates with isolation paper when printing. Version of the surface has a layer of light protection film, so you can Ming room operation. In the version of the plate with the aid of the plate can be automatically peeled off the plate surface of the film, so that the plate material to participate in the plate.

Plate material fixed on the drum includes: full adsorption and intermediate adsorption, head and tail fixed with the card clip two. The full adsorption type has no limit on the size of the plate, and the plate size used by the clip type must be fixed.

30% of CTP equipment has a punching device, the general punching process is carried out after exposure, which can ensure the accurate positioning of the printing plate on the press, reduce the pre-press preparation time of the printing roll adjustment, improve the printing quality and overprint, positioning accuracy.

Type of plate

Plate base is divided into: metal plate and polyester plate, metal plate is mainly aluminum plate, high printing resistance, suitable for long plate printing, and polyester plate is more suitable for short plate printing needs; According to the coating can be divided into photosensitive resin version and thermal version, the former is suitable for medium and long version of commercial printing, plate making speed, and the latter can be processed in yellow light or UV filtering sunlight, plate making quality is the best.
