Thanks for explaining your reference. I couldn't figure out what you
were getting to regarding the heat of the lamp. Perhaps the original
poster had curable UV inks in mind and I'm the one that's
misinterpreting his needs.
I suppose one could still use a UV cured ink with an inkjet (if the ink
would be able to get through the head) as there are no heat or minimal
heat UV LEDS and also fibre optic delivery of UV, or it could be cured
outside of the printer, once the media or product was ejected. In fact,
one certainly wouldn't want the UV source anywhere near the head, or the
ink would cure and seal the head closed pretty darn quick!
I think one of the reasons for using UV curing over heat curing is that
there are a lot of ways to deliver cool UV, since it is a cool wavelength.
