vacuum/exposure systems. The Expo-NV's dynamically balanced and
focused-beam fluorescent tube system helps ensure good, clean stencil
definition, screen after screen.
To add versatility, the Expo-NV can also be used as a light
table.Simply place a durable, high-density piece of translucent
fiberglass over the glass exposure surface, flip a switch, and you now
have two machines in one!
If you want to save money, this is a good exposure unit -- backed by a reputable company.
