In the details you can spot the printed fluorescence:
In the white background you can just see the -45/45 angle screen. Take some distance from you computer screen if necessary!
It is very visible under the black cancellation!

the German Post Office official statement is that a traditional fluorescent coated paper has been used - DP2. What I am trying to show is that this is b*llsh*t! The fluorescence had been applied by printing it!
About 60-80cm was enough for me, also turn your head some 45 degrees .....
Turn the head so you can see the black dots in the cancellation or the design horizontally!!!! Doing so, you will see the white dots in the background!!!

Hi Rein
You have eagle's eyes !!
I can see perfectly the "white" fluorescent dots in your images.
This dots are printed over or under the image of the stamp? Like "overall tagging" or "previous" offset (litho) printing?
Greetings
Jorge

Jorge,
the white dots are on top of the other colours! I can see them on the red print but unfortunately I cannot scan it that way so it would be visible on the scan as well....

The first printed fluorescence can be found in 2008. Not always can you see them so clearly! It is good tolet the cancellation ink help you!
The screen angles in the cancellation are the same as in the white background!
