UVB or UVC?

UVC bulbs are a non-existent entity in contact printing devices, and should remain so. You don't want to mess with UV-C radiation in a quasi-open system like a contact printer for risk of eye injury and skin cancer. It's also completely unnecessary for alt. process printing and probably extremely inefficient since the peak sensitivity of alt. process materials lies significantly beyond the UV-C band.
 

Yes, I do agree. I am just wondering what other kind of UV there is because most of the UV bulbs I see and the halogen ones people post online are blue in colour.
 

What type would you recommend to shorten the times?

Sorry to OP for sort of hijacking the sales thread.
 
Wondering why your ad looks familiar....

 
I am interested I live in Las Vegas and I don't mind driving there but it wouldn't be until the weekend, but I can pay you whenever. I'll DM you.
