The PlateRite 4600E is an affordable, entry-level platesetter, which will provide printers with the most cost-effective way of incorporating the latest high-quality thermal CtP technology into their business and is upgradeable all the way to a PlateRite 4600Z which has a productivity of 33pph.

With increased flexibility in format support and even greater plate productivity, 33 plates per hour at 2540 dpi, the PlateRite 4600Z is ideally suited to meet the requirements of even the most demanding printer. The PlateRite 4600E/S/Z inherit all the features that have won the PlateRite series its reputation for high quality, high accuracy, and high reliability. This makes it a singularly attractive choice for the small or medium size printer with B3, B2 plus presses looking to enter the CtP market. Together with SPEKTA 2, which is Screen’s hybrid FM/AM screening technique, this is a CtP package that will set standards in quality and productivity.

Versatile, easy to use and output suitable for 2-page or 4-page presses

The PlateRite 4600 family can handle the plate requirements of new larger-format 4-page presses. Both support a maximum plate size of 830 x 660 mm (32.6" x 25.9"), and are also capable of supporting some of the smaller 2-page presses with a minimum plate size of 324 x 330 mm (12.8" x 13")*.
The PlateRite 4600 range offers an unbeatably flexible and reliable solution for fast output of a wide variety of plate sizes.

* 304 x 330 mm (12" x 13") support is available as a factory option.

Auto-balance for different plate sizes

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 4600s automatically make the necessary adjustments to create perfect drum balance for each plate size.
The PlateRite 4600 also feature separate loading and unloading bays, so that one plate can be readied for loading while another is being exposed.

Bring out the ideal CtP environment with a simple upgrade

For the ideal environment for your increased productivity needs, you can upgrade your PlateRite 4600E to the PlateRite 4600S or even PlateRite 4600Z* by simply exchanging parts required for the PlateRite 4600E.
This reduces wasted expenses and improves the operational efficiency of your platesetter.

Productivity-enhancing automation

Optional inline punching and automated plate loading
Automatic inline punch

Screen’s automatic inline punching system is the industry leader for enabling perfect register on press. It does this by performing two types of punching (for press and platesetter registration) at the same time, immediately before mounting the plate on the drum.
This method gives much greater registration accuracy compared with either manual or off-line punching, eliminates human error and achieves faster press makeready.
Punch blocks from Heidelberg, Komori, Bacher, Protocol, Stoesser, Grapho Metronic and Screen are available, covering the full range of sizes for all major press types. Up to four punch blocks can be mounted and selected according to plate size and press type.

Autoloader options

The PlateRite 4600s can be configured for efficient automatic operation with Screen’s optional autoloaders, which are acclaimed in the market for their reliability and precision. The complete PlateRite 4600 family can be paired with the SA-L4600II single-cassette autoloader.
This high-quality unit can hold up to 100 plates and automatically removes interleaf paper before loading each plate.
It is also possible to upgrade from the SA-L 4600 to the MA-L 4600 multi-cassette autoloader, which comes standard with three cassettes and enables up to 300 plates of three different sizes to be loaded and imaged in the PlateRite 4600s without operator intervention.
