Was Scott 1036A Printed On Bright Paper?

I was sorting through some Liberty series plate blocks recently looking for tagging varieties and I found an example of the 4-cent Lincoln on much brighter paper than all the others. In the series of pictures that follow the PB in question is on the right while I put an untagged example in the middle and a tagged variety on the left.


Under short wave UV, the normal tagged variety on the left lights up like it should but the one on the right looks a little off.


Switching to long wave UV, the brightness of the one on the right really shows up.


Looking at the backs with the long wave UV shows that it is the paper that is driving the 'glow'


My 2016 Scott specialized mentions the tagging variety but makes no mention of any paper varieties. Any US specialists out there (especially anyone fluent in Liberty Series stamps) have an explanation?

Hopefully the UV pictures aren't too dark to see.

Thanks,

Joe

The right side block looks like it is printed on "Hibrite" paper. The Scott ( specialized ??? ) catalog as usual omits this info

Thanks Peter. I also had another dealer confirm that the Liberty Series is known on Hi-brite paper but Scott does not list them. Oh well, at least I now know what I have...

Thanks for the input.

There are a number of stamps in the liberty series on a "hi-brite" paper as they have been referred to. Note these hi-brite papers are not the same as modern hi-brite papers. You can find listing for these in the tagging database.
