BasysPrint – founded 1995, and today a Punch Graphix company – set itself the target of developing a technology which would unite the principles of CtP with the benefits of the proven, conventional UV plate technology. The product was the basysPrint UV-Setter. Implementing the unique DSI (Digital Screen Imaging) concept, basysPrint’s UV lamps or violet laser diodes are able to process more than 50 brands of UV-sensitive printing plates from 15 different manufacturers. The UV-Setter has been enjoying tremendous success worldwide for over 10 years, handling the most varied applications in the format classes 2 - 9 (up to 1535 x 3170 mm).

Digital Screen Imaging (DSI) process

To directly expose data, basysPrint - a Punch Graphix brand - has developed the Digital Screen Imaging (DSI) process, based on Digital Light Processing™ (DLP™) from Texas Instruments Inc.

   

In this process, UV light hits a DMD™ (Digital Micromirror Device™), a component with approx. 800,000 of micromirrors. Each of the micromirrors can be digitally controlled - the mirror either projects the light that it receives through an optical lens system or it diverts the light such that the lens does not catch it. This means that each mirror is like a pixel; a screen image is created on the printing plate. Due to the limited number of micromirrors or pixels, only some of the sections of the image can be projected in one exposure step. These picture segments are joined to form a composite picture by a rapid succession of exposure steps. The picture segments are approx. 0.8 cm to 6.3 cm in size, depending on the resolution selected. The highly precise positioning system of the exposure head ensures precision of 2 µm for seamlessly joining the picture segments.

The UV-Setter Series can be ordered in the following automation levels in DSI² and DSI³:

  • Manual and semi-automatic: Even in its basic manual version, the UV-Setter stands out by way of its ease of handling and quality. The first option is to configure the UV-Setter as a semi-automatic system with automatic plate transport to the processor.
  • Fully automatic system with single cassette: The fully automatic SCA version (Single Cassette Automation) can hold up to 100 plates of a particular format in a cassette. Further plate formats can be made available by way of an additional trolley.

    • Manual operation possible, if necessary
    • Fully automatic paper removal
    • Optional automatic punching
    • Plates can also be loaded up during exposure

  • Fully automatic system with multi-cassette: The MCA version (Multi-Cassette Automation) accepts up to five different plate formats and automatically supplies the required format for exposure.
    • Up to 500 plates in max. 5 cassettes
    • Manual operation possible, if necessary
    • Fully automatic paper removal
    • Optional automatic punching
    • Plates can also be loaded up during exposure
