Product Details:

Screen Thermal CTP Machine is unbeatable for their quality, accuracy, and reliability. They consistently output plates with a dot sharpness and registration accuracy that enable superior process control and fast makeready times. They also offer the benefits of easy daylight handling and exceptional production efficiency for both short and long runs.

Screen’s PlateRite 4300S and PlateRite 4300E are specially designed to provide optimal versatility in plate production for 4-page and 2-page presses. The PlateRite 4300S is a high-speed model that can comfortably and consistently output up to 21 plates per hour when working with 724 x 615 mm (28.5" x 24.2") plates at 2400 dpi. The PlateRite 4300E is an affordable entry-level solution that offers the same high-quality features as the PlateRite 4300S, and provides output at up to 11 plates per hour. Both models have a proven external-drum design and come with the option of inline punching blocks to help ensure perfect on-press register and faster makeready times.

The choice has never been easier for making the move to high-quality thermal CtP.

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 4300S and PlateRite 4300E can be configured for efficient automatic operation with Screen’s optional autoloaders, which are acclaimed in the market for their reliability and precision. Both the PlateRite 4300S and PlateRite 4300E can be paired with the SA-L4300II 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 4300II to the MA-L 4300II 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 4300S without operator intervention. Both the PlateRite 4300S and PlateRite 4300E are supported by an automatic processor bridge, which extends process automation all the way through to the plate processor.

Product Details:

Flexo Plate Making Machine a great fit for you. It comes with different optics depending on your needs. Optics 25 give the fastest throughput for this model. 

The CDI Spark family offers a wide range of digital flexo imagers for plates for different markets: from a small footprint imager to very large, for the tag and label, flexible packaging, small and medium folding carton to corrugated market.

Benefits:

• Reliable productivity
• Choose an imager that grows with your company
• Proven laser imaging technology & high resolution optics

The digital flexo plate has a mask layer – sensitized to the CDI’s laser light – on top of its surface. After imaging, this mask takes the function of the traditional film negative. Through the integration of the image carrier, a digital flexo plate has sharper image definition and steeper relief shoulders than conventional plates produced with film. Image deterioration by UV light absorption and scattering in the traditional contacting through vacuum sheet and film is totally eliminated.

The CDI technology provides a major breakthrough in enhanced output quality and consistency, with reduced overallprocess cost.
