Screen PTR4300
4-Up Thermal Computer to Plate

Screen PlateRite 4300

The PlateRite 4300 is a 4-up thermal platesetter capable of the superior quality and productivity. With its state-of-the-art 32-channel laser imaging head, the PlateRite 4300 images up to 4000 dpi, outputs 20 plates per hour at 2400dpi, and continues making plates even if a laser burns out, so the presses are never waiting because pre-press can't supply them with plates. Automatic in-line punching and Screen's Auto-Balance system ensure repeatability within plus or minus 5 microns. With the optional auto plate loader and processor transport bridge, plates can be loaded, imaged, and processed without operator intervention.

  • In-line punching
  • Separate loading and unloading bays, so the next plate can be loaded while the first one is being imaged
  • Automatic laser channel power balancing
  • Optional Autoloader and processor transport bridge
