New high-end model delivers outstanding performance for 4-page thermal CtP systems!

SCREEN's new PlateRite 4600Z, S and E CtP systems enable consistent production of high-quality printing plates.
The high-end PlateRite 4600Z 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 a small size option that supports minimum plate size of 270 x 330 mm (10.7" x 13").*
This option provides greater flexibility when using letterpress and a wide range of other media.
* The minimum plate size available with the standard specification is 324 x 330 mm (12.8" x 13").


Auto-balance lets you use different sized plates without making any manual adjustments for correct drum balance.
All you do is select the type of plate you want to use and the PlateRite 4300S and PlateRite 4300E automatically make the necessary adjustments to create perfect drum balance for each plate size.
The PlateRite 4300S and PlateRite 4300E also feature separate loading and unloading bays, so that one plate can be readied for loading while another is being exposed.

Wider Range of Plate Sizes

Improved support for small size plates (optional)
