The Exposure Unit plays an important role in the quality of your screen printed product. All Workhorse screen exposure unit systems feature digital time control for accurate and repeatable screen exposure times and a powerful vacuum hold-down system that provides intimate film to screen contact for maximum image resolution. If your plans call for producing a moderate number of simple, athletic type designs, the LUMITRON or LUMINATOR screen expoure unit may be all that you will ever need. To produce a moderate number of higher resolution designs, choose the POINT 1000 screen expoure unit. If you want to produce a high number of screens of the highest possible resolution choose the PHOTOSHARP screen expoure unit.
