Hi everybody! I have a question about making cyanotype exposures in a UV platemaker, or similar UV exposure unit commonly used in photo-based printmaking processes (light sensitive lithographic plates, for example.)
Namely, using Christina Anderson's 2A:1B formula, and digital negatives, she suggests 6 minutes under UVBL lights... does anybody know exactly what that would translate to in terms of an exposure unit that is set based on light units, as opposed to time?
I will not have access to this particular platemaker (I do have one that has a time setting) until I'm on-site, so I'm hoping to have a good ballpark in mind to cut down on wasteful experiments once I am there.
Thanks very much for your help!
