OK now for real world example.
I printed a 918 test chart which was allowed to dry for 3 days, this was measured with i1Pro and measure tool in PM 5.09 with spectral enabled, I did several measurment, and all were very close to each other, I created a profile using Profilee Maker without the correct for optical brightners switched on. The software recognised there were OBA in the paper. Paper is Hahnemuhle Fine Art Baryta.
Same measurement were done with another i1Pro but this time it is UV cut, also created many measurement and then a profile in PM5.
Printed two test images withe two profiles, and I can't see or tell any difference at all, under different viewing conditions. Is that may be due to the paper having low OBA.
I was expecting the UV Cut profile, to give a blusih cast under uv light, as this was not compensated for with yellow ink, and normall indoors, where the profile measured without filter, I expected normal color under UV light due to extra yellow ink to offset the increased blue from the OBA and slight yellowish indoors, as there is no UV light to react with paper, well that is what these forum led me to beleive.
Have I missed something along the line ssome where?
Thanks in advance
