Screen Exposure Units - Main Differences
With a great many features on all our screen exposure units, it may be a little difficult to decide which unit is right for you. In the OPTIONS tab you can find the full specifications for all units, but here is a quick run-down on the main differences to help -
Entry Level (Yellow) vs Premium Range (Green)
The main differences between the two ranges come down to the following -
- Analogue controls on entry level devices vs digital on premium range
- Smaller maximum screen size on entry level device - 21 x 24" vs 23 x 31"
- No legs supplied with entry level device - desktop model only. All premium models come with legs as standard and can be used as desktop or freestanding
- Lower output UV tubes in entry level models mean longer exposure times

LED Unit Guarantees
LED is brand-new, cutting edge technology, but Vastex is so confident about the quality of their units that they are offering the same guarantee as on existing UV units. The most likely problem on LED screen exposure units is likely to be failure on a single LED, so the light bars will be repaired during the guarantee period should this occur.
We will supply full assistance to help you remove the faulty light bar for return to us for repair. We are able to supply a light bar on loan while yours is repaired to ensure you have uninterrupted use of your equipment if needed.
Need More Speed? The Benefits of LED
LED screen exposure units feature long-lasting light emitting diodes that provide ultra-fast exposure times - around 10 to 15 times faster than ultra violet (UV) and comparable to metal halide, while also capable of reproducing very high resolution images with halftones and intricate details.
Maintenance costs on LED exposure units are substantially lower than metal halide with a much reduced level of overall power consumption and life expectancy that can exceed 50,000 hours.
LED exposure units also start instantly, requiring no warm-up time and stays cool during operation. The light intensity from these units also remain uniform from one cycle to the next.
Add a Screen Drying Cabinet
A screen drying cabinet will drastically cut down on the time needed to dry screens. They are also a great way of preventing contamination of wet emulsion during drying.
