What do I look for when getting an exposure unit?
Choosing an exposure unit will depend on your budget and what kind of prints you plan to do. You definitely should get an exposure unit that at least has LED bulbs (check out this article to learn why LED is the new standard).
Another factor you’ll run into is whether you should get an exposure unit with a compression or a vacuum lid. This blog goes in depth between the two, but again, your budget and prints will determine which unit to get. Have a low budget and/or plan to print mainly spot color prints? A compression unit will work great. If you have a bigger budget and/or plan to do highly detailed prints, you’ll need a vacuum unit.
