UV exposure for inkjet plates

Conventional UV exposure units are typically large, heavy and complex machines. This is mainly due to the use of high-power UV lamps, which require a certain distance to ensure uniform exposure, as well as vacuum systems needed to keep the film in perfect contact with the plate.

In the case of inkjet-based plate imaging, vacuum is no longer required, as the ink mask is already in direct contact with the photosensitive surface. In addition, modern LED technology eliminates the need for large exposure distances while maintaining uniformity.

As a result, the StudioRIP UV exposure unit is significantly more compact, lightweight and cost-effective compared to traditional systems.

Models

• StudioRIP DTP 24 exposer: maximum 525×459 mm plates
• StudioRIP DTP 36 exposer: maximum 605×745 mm plates
• StudioRIP DTP 44 exposer: maximum 1030×770 mm plates

Specifications

• Compatibility: inkjet-imaged plates (no vacuum required)
• Plate size range: from 459 × 525 mm to 770 × 1030 mm
• Exposure time: approx. 40 seconds per plate
• User interface: 3.5″ color touchscreen with graphical interface

Technology

• The plate is inserted in a near-vertical position (slightly inclined for stable positioning)
• A LED panel is positioned parallel to the plate surface
• The exposure distance (40 mm) is optimized to ensure highly uniform illumination (max. ±2% variation)
• The 3.5″ touchscreen interface displays a progress bar and the exact remaining time
• A built-in exposure history prevents accidental double exposure of the same plate
