4 page Thermal Plate Recorder
New high-end model delivers outstanding performance for 4-page thermal CtP systems!
SCREEN’s new PlateRite 4600N-Z, S and E CtP systems enable consistent production of high-quality printing plates. The high-end PlateRite 4600N-Z delivers an impressive throughput of up to 33 plates per hour.
The exposure heads used in the PlateRite 4600 series have been enhanced with the addition of new fiber laser diodes. These diodes enable the reproduction of sharper halftone dots, significantly improving print quality.
All systems can also be equipped with an option that supports plate sizes smaller than the standard settings (270 x 278 mm).
Wider compatibility boosts efficiency and eco-friendlinessOptimized production line using process-less plates
All PlateRite 4600N models are compatible with process-less plates offered by a range of manufacturers. These plates greatly reduce both the chemicals and electricity used in processing units after exposure.
All models also support waterless plates, which eliminate the need to process waste liquid (dampening solution) and significantly reduce environmental impact. The PlateRite 4600N series makes it possible to choose the optimal printing method and plate type for any situation, enabling the construction of a highly flexible production line.
Autoloader maximizes productivityAn autoloader system can be installed to automate all processes from plate loading through exposure, transport and developing to discharge.
Two types of systems are available. While the SA-L4600N single-cassette autoloader accepts one cassette containing up to 100 plates of the same size, the MA-L4600N multi-cassette autoloader can handle three separate cassettes with up to 100 plates each.
Wider range of supported plate sizesImproved support for small size plates (optional)
The PTR4600N can handle plate sizes ranging from a minimum of 270 x 278 mm (10.7" x 11") right up to 830 x 680 mm (32.6" x 26.8"). This makes it compatible with an even wider variety of presses.
Some limitations apply regarding support for optional media sizes. Please contact your nearest SCREEN sales representative for further details.
Accurate reproduction of halftone dots with exposure headsTo ensure more stable exposure, the light source is equipped with the same proven fiber laser diodes used in the PlateRite 8600 series. The resulting changes in the laser beam produce more accurate vertical and horizontal lines, enabling sharper reproduction of halftone dots. This has led to a major increase in overall print quality.
