Different Color Paper On Stamp #1369

Hello everyone. I am new to the site and relatively new to stamp collecting. I noticed that I had 2 of the same stamp but the paper on each stamp seemed to be of different colors. I included a photo. I'm not sure if the color in the photo will look accurate. One is more beige/pinkish and the other is basic white. Is this normal to occur? Could this have been caused after the stamp was created(by fading or environment)? Is it an error of some kind? Thanks in advance for any help.

Hi Goon, and welcome to the forum.
As for the paper, sometimes the paper vendor changes. It is also possible that the chemical composition of the paper changes due to the addition of brighteners for instance. It helps if you can check your stamp with Long Wave Ultra Violet light'
Of course, your thought of environmental changes is also possible.
By the way, the best way to show off the paper is to use a matte black background.

Different methods of printing? The red looks inconsistent on the right (highs and lows in the ink colour while the one on the left looks smoother) could be the image threw my screen
If they are printed only rotary, I'd say a bad wipe on the roll

Utter nonsense

Meh, could be my screen was just a guess

Seems some coffee is needed. Might be useful to clarify exactly the 'nonsense' to our first time poster. Just a thought.

Fair enough.




No, these were only printed one way. (see below)




These were lithographed.




We are talking about the brightness of the paper.

IMHO it is a disservice to throw a bunch of junk at the wall to see if it sticks when a newbie is asking a serious question and lots of magnified photos of stamp portions add nothing in this case.

Sometimes it just feels like we are being trolled and it sucks up a lot of oxygen.

Cheers

Sorry you feel that way,
I'm not trying to troll anyone, I just asked a question and gave a guess,
My bad

Like this one?

Best one is that he found a supporter. Not the slightest trace of doubling. In fact




where the left side and right sides are printed double, individually.

I'm sorry,
What exactly would the benefits of a person's opinion here without a certificate to go with it?
Could I send in your opinions to get a cert, would they care?
Does anybody post the links for sale reference, would you buy it?
I really don't care in the way you may think, I'm just looking at stamps

I'm not trying to troll I'm learning and asking questions
Opinions never hurt either

It appears the left one is either on paper that has become toned due to poor storage or poor plate wiping.

Most likely caused by the varnish used for the taggant. On many of these early issues the varnish can yellow/darken due to various environmental effects. You can see this when you at the selvage of plate blocks from this timeframe. Part of the selvage can look fairly white/bright and part can look yellowed/darker.

Mstocky - That is interesting.

mystocky- fully agree with your assessment. Tagging omitted errors can be first detected by noticing whiter selvage in a stack of plate blocks for instance. Tagging of this era tends to be grittier to the touch as well. But, of course, nothing verifies tagging better than a lamp.

Looking at my samples there is mostly likely a combination of factors at play. First is the yellowing of the varnish as mentioned. In these two samples you can see the difference. Also notice the untagged area in the selvage.


Second is paper fluorescence. This issue can be found on a low fluorescence and dull fluorescence paper. The image below is taken under LW UV. The left stamps are on low fluorescent paper and the right is dull. The low fluorescent paper has a bluish tint to it under LW UV. This also contributes to the left stamps paper looking whiter.
