Hi all,
I have some questions about the i1pro UV and hope the group can help.
I looking into purchasing one for linearizing and profiling our epsons
using colorburst/spectralvision pro which "requires" the UV filtered
version.
We have a regular i1 which we use for taking sample readings from a
pretty wide range of original documents, photographs and artwork. I'm
wondering if I will get consistent readings from most of these
materials. When measuring materials the "do not" have any optical
brighteners would you expect to see identical readings from both the
regular i1 and the UV i1? How about monitor profiling. Has anyone used
a UV i1 for calibrating and profiling a Eizo Coloredge (various
models)? Any difference between UV and non-UV for this prurpose?
Thanks in advance for any advice.

Theoretically, yes.

The UV is emitted from the i1's illuminant, which isn't used for
emissive measurement. So again, theoreticaly, there shouldn't be a
difference here either.

I would keep your non-UV EyeOne for these measurements, if possible,
as it's nice to look for those OB spikes. As for consistency between
the two, it sounds like you'll be able to test that for yourself soon.
How about monitor profiling?
Spectros like the EyeOnePro have proven to be inferior to a good
colorimeter (like the DTP94 or Spyder3) for display calibration.
Display calibration is terribly important - fortunately, top notch
display calibration packages with colorimeters are only a few hundred
bucks. That's money well spent.
