Digital BW, The Print

Some time ago I tested several of these.One I tried, Krylon UV clear, did indeed block UV to an extent as checked via before and after with a spectrophotometer. Unfortunately, it also slightly blocked visible blues so caused a bit of yellowing to Hilights and paper base. I don't have the numbers handy at the moment so can't quote figures.

Regards, Duane
