POP paper and it's initial and final colours

Hello Alt friends,
I have been noticing the colour of an initially printed -out paper contact from use in the UV printer compared to one printed in the sun.
The prints from the UV printer, (an Edwards printer), is much cooler and tones cooler and lighter than the print printed out in the sun.
I can always tell from the finished prints whether I used UV/ sun.
Does this have to do with the intensity of the light sources?
I have been working with these materials for a long time and I finally realized that I need to have an answer for when someone asks me. Thanks,
Susan
