Digital BW, The Print

> From what I've found on the web, the Clearshield varnishes have great uv protection but show some yellowing in a short period of time but doesn't deteriorate much after the initial yellowing..., where the Premiere Art and similar sprays do not show yellow tints. Am I mistaken? 

I use Premier Art's PrintShield myself, on matte paper. It's not at all glossy or even a semi-glossy spray, the print shows no difference before and after. At the same time, it affords some moisture resistance and UV protection.
