Foro de Filatelia Argentina

Traditionally the paper surface wa supposed to be as smooth, flat as possible in order to get the best printing results!

But since around 1970 the paper industry seems to have adopted the tendency to have walls painted with structurized paint or wall paper instead of flat ones....

How exactly this structure was applied in stamp paper is not known yet as so far no philatelist has been bothered to pay attention to it - let alone wirte about!

I started to write about a very typical paper surface once noticed in the Mexico Exportas but later on also in the German commemoratives since 1975! But at least the German collectors were not pleased to find out they had to pay more atttention to their contemporary stamps

Still a paper surface with no or hardly any additional structure!?




With some structure:




Typical here is the rather hollow shape or width of the grooves!

Or with quite some grooves:

With a very clear paper sieve structure! Rayado!



but also with a clear, applied to the surface in a later stage, structure!



Paper NOT coated!

No paper sieve structure visible!



Clear paper surface structure!



Paper NOT coated!

The various structures can also be seen at the front of a stamps as well as with coated papers!

But what was the sense of "ruining" the paper????




Hardly any structure as the back:

In 2001 the German Women definitives were issued with face values in both Mark as well as Euro - so-called "dual" system...

Both smooth ,flat surfaces can be found as well as structurized :

The German flower definitives were printed in reel-fed offset-litho on coated paper, also an APS perforation was used.

The surface of the gummed side is either flat or rough - structurized!

The structurized surfaces occassionally show somewhat deeper grooves!!
