Some Lights It Hot, Some Lights It Cold
Forgive me the headline, I'm atoning for a life of typos... Seriously though, I have a real question... I use a bank of UV BL fluorescents to print my work (a la Eepjon). I've been weeding out the errors, big and small, in my process lately. I find that when the are hot, used within the last half hour, they are anywhere from one-third to two-thirds a stop faster than when the lights are "cold". The difference makes printing to highlight and calibration (using the term loosely) a real pain. I know on commercial units there is a sensor which calculates how many "units" of UV has been emitted so the operator can compensate. Has anyone built a similar switch for the smaller light boxes? ~m
