Thanks to Stamp Smarter's tagging database, I was checking my #3112, 1996 Christmas Madonna and Child stamps for luminescent yellow ink using Long Wave UV.
I decided to also check them for tagging with Short Wave UV.
I was surprised to see that I had 7 examples with regular solid tagging with the tagging glow disappearing as soon as the UV light was turned off and 4 examples where the solid tagging was phosphorescent with the tagging continuing to glow after the UV light was turned off.
The Stamp Smarter database did not seem to address this difference or identify different types of tagging for this stamp.
My 2014 edition of the Scott USA Specialized also does not identify any tagging varieties.
Does a more recent Scott USA Specialized ID this tagging difference?
Can anyone "illuminate" me on the tagging differences with this stamp?
Thanks!

On another stamp forum, I learned that some people add liquid dish soap to their water when they soak stamps. Adding liquid soap is not recommended because it can contain optical brighteners to make your dishes look cleaner. The optical brighteners can then cause your clean stamps to glow under UV and other light sources. Perhaps this could be an explanation for what you are seeing.
