Depending on the sensitivity of the emulsion you use, you can still get fast exposures with the HIX TT-180D bar lighting system, which consists of six high output actinic UV lamps. Light scatter has always been an issue with bar lighting systems, but the deep draw blanket powered by a 115 Volt vacuum pump holds the art and screen so tight that any undercutting by light is held to a bare minimum. The digital timer and auto-shut off are standard on this unit which will hold screens up to 23” x 31.” The digital timer also ensures more accurate and precise exposure times. This digital tabletop unit has all of the standard features, including an auto-reset timer, cycle start switch, separate vacuum, and main power switches.
