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)
