Hello to everyone!
I just read this topic and it's very interesting but I think it's not so clear viewing it by pratical means..
I don't know if the information I will give can be usefull but I'll try! :)
I own two spectro,
1 is a UV cut X-rite I-one.
2 Is a non UV cut I-one
Using a UV-cut spectro is necessary if the support where you print the patch for linearization or calibration purpose has too much UV reflecting coat.
I also have a Wood lamp to test for paper or print support in general.
If it's shine I use a UV cut X-rite I-one
If I try to make a calibration with a non UV cut spectro with a paper that reflects too much UV light I have a color space not as big as I use the UV cut spectro..
This is because the Uv component of the light that the media reflects is red by the spectro and get a false value.. ( The spectro read an higher bightness that the real brightness)
