1943 P&R I - unknown type of paper! Overlooked for 60 years!

Rein:
There are too many color fibres as to be overlooked!!! I thing the stuff used for the tela paper should had some fibers
that reacted ro some element not existing in our country. It would be necessry to nalyze in a paper laboratory what fiber it is. We have the INTI here but they charge for it,
On the other hand I was talking to Nora Mattasi, CdM Museum, that confirmed no varnish was ever applied ro Argentina stamps after printing. She was talking with various members of the printing areas and they only say that perhaps, in some papers, the printing cylinders, due to great pressure they excert, might produce a calender effect on those papers.

José,

I do not exclude that option, but you should at least in the stamps concerned find these rather longish fibers while they are still white! And I keep finding them, the 40c yesterday, today some more! All from Germany! I know we had Czernobyl and now we have Fukushima!

I hope you will find copies yourself soon to get the option to let it analyze!

As to the varnish I think the experts in the Casa de Moneda are wrong! I can imagine the Giori press exert such pressure in recess printings, but not in the offset-litho presses... There are too many examples where the gloss is on top of the ink! It is a pity I do not live a little bit closer to you

Tony,

watch out for the brown fibers!!!

According to José Merlo, the brown fibers are just an chemical change due to the water in the Northern Hemisphere! The fibers probably curl differently due to the Coriolis-effect!

There is another dilemma when attributing the colour change to the use of Northern Hemisphere water in soaking off the stamps!

As said before, the paper was manufactured in a paper mill in Scotland where loads of water must have been used while producing this type of paper. I have heard before the possibility of the water - more or less muddy - could affect the colour of the paper! The whiteish/cremeish shades could be explained by the amount of mud in the streams....

What we see clearly here is - both for the 30/20 density and the 24/22 [Tela] - the presence of other coloured fibers! Not just brown ones but also red ones, and orange and yellow, even black ones....

The gumming took place in Scotland, the gum got partly removed in Argentina and replaced by Argentine saliva, the stamps flew to Europe or the USA, got soaked off over there and WHITE fibers got coloured - in a range from yellow, orange, brown, red and black....

Similar bunches by the same paper mill but somewhat later - since 1947 and using a different wire - is NOT known with brown fibers so far, BUT with GREEN and black! I am curious whether these "rayado vertical" stamps were found in Argentina with green fibers????
