Germany - 1948 - Hegel Portrait 60 - Fluo Ink

Hi,

Is each portrait exist with fluo ink like that?

This is the only one I have with fluo ink. It's interesting.





Thank you!

Probably soaked off in the same pot with modern stamps, and took up some of the fluorescent material. Nobody had dreamed of phosphorescence when that stamp was issued, as far as I know.

Hi Doug2222,

What I don't understand... only ink is fluo. Paper is normal. It's very weird but interesting. No fluo on back too.

Thank you!

Hi,

The ink is completly green when I use a fluo lamp near. If you have one like this, it's sure you will see highlight difference. Look like green phosphor.

Thank you!

CDNum.

It does appear that the ink is fluorescent. If you look carefully, only the ink and not the paper is fluorescing. I feel that another explanation, other than soaking with more modern stamps, is needed. It is not unheard of that older stamps do fluoresce, either by accident or through design.

Hi,

I read about phosphor ink. In this case, it's probably "PREPHOSPHORED INK" method because only ink is fluo and not paper. I thought stamps with fluo began in 1960+... seem not be the case.

I certainly don't have the answer to this, but I see the stamps, originally issued in 1948 were reissued by the DDR in 1953. The two issues had different watermarks. Watermark #292 (1948) and #297 (1953).
Can you determine what watermarks the stamps have and narrow down the issue year? Still too early for fluorescent ink, but it may help figure something out.

Hi Jamesw,

Yes, I know that and I cannot see wm on these stamps... I tried yesterday and this morning. I have lot of problem with wm :-)

WM can be the answer but i'm not sure. Maybe someone know that?

Thank you!

Hi,

I try to have additional info about this stamp in European country. If I have more info, I will share it with you.

Thank you!

Natural substances do show fluorescence / phosphorescence, and it's certainly possible that the ink contains a component that fluoresces, regardless of the time period in which the stamp was printed. A notable example of that is the rare eosin colour variety on Australian KGV one penny side-face stamps. The ink is pinkish red, but it shows up as yellow-orange under UV light.

In fact, the huge number of red shades on those Australian KGV stamps are often distinguished from one another by their fluorescent characteristics. Not exactly what you'd expect from stamps printed around the time of WWI, but that's the way it is.

The image below was pilfered from another chat board. It shows the strong difference in colour when viewed under UV light (these stamps have relatively minor differences in shades when viewed under normal light). The page below describes, among other things, the difference in UV reactions for the shades found on these 90+ year old stamps.

Thank you for these information Ryan.

Hi,

If Germany stamps specialist have more information about that, I will appreciate your comments.

Thank you!

To add to cdnum's conundrum I also have a 65 year old German stamp
printed in fluorescent ink.
So cdnum, you are not alone.

Many years ago when I first got my Raytech UV lamp I checked just
about every stamp I had.
When I saw that the engraved ink on this 1947 German Allied Occupation 1Mark showed up light fluorescent green compared to brown on the other one I had, I was stunned.
I checked Scott and Michel but found nothing so I forgot about it until now.
No internet in those days.

Anyway I tried to take a pic with the digital camera but it just
doesn't turn out.


Germany Allied Occupation Michel 959 issued in 1947 in different shades





The one on the right has the fluorescent ink.

This stamp, part of the definitive Kontrollratsausgabe, was printed one colour engraved by the State Printer in Berlin
whereas the one cdnum showed was printed via typography by Giesecke & Devrient, Leipzig which was then under Russian occupation.

Your stamps are part of "The Heads" series, "Die Köpfserie." As previously mentioned there are two issues, one issued by the Soviet occupation authorities in 1948, the "Heads 1" and reissued in 1952/53 by the DDR, the "Heads 2." The difference is the watermark.

This is a fly-specked series. If you want to get into the weeds, there is a German study group that has a website devoted to it.

Some of the Heads 1 stamps fluoresce under UV light. I have not found an explanation why. Since they are only color variations, I suspect Ryan's explanation may be the answer.

Here is a Pdf compilation of the different variants of the "Heads 1" It's in German but you can see the color changes for some variations under UV light.

It is an imbedded file and I can't seem to give you a direct link. Click
http://www.koepfe1.de/navigation/typset.html and then
"Katalogisierung" on the left column and then [Katalogisierung in der Fassung vom 23.04.2012] (Note: It uses an old Adobe plugin so you may get a warning first.)

Hope this helps!

Hi Lithograving and Danstamps54

Lithograving :-)

Danstamps54 : I use google to translate and it is a very interesting Germany study.

Thank you!
