Too groove or not too groove!

[Rein]

The occurrence of grooves [surcos] in the surface of the stamp paper is worth studying! I mentioned it on several occasions in relation to Argentina stamps.

It also proved that the wire side of the paper quite often had been used for the printing of the stamps! A fact that is not so widely accepted....

In coated papers at times the paper makers really mess things up! The results are awful!

I´m thinking if the roll that takes the paper from the wet section in some cases could be "guilty" of grooves on the felt side of the paper, except of course when the felt side has been gummed.

José,

the effect such roll could make is restricted (the paper is not that wet at that point] although we can expect something occasionally! Like the brown fibers - have you had a look a them ??? - coming from a "dirty" felt roll!

The grooves we find in modern, coated papers are there systematically! And the surface of the opposite side of the paper is always very flat and even!

Rein,
I can´t imagine another cause. As for the brown fibers I wasn´t able to see them yet.

José,


I hope you will find time to have a good look at the brown fibers as they ARE there! What made them there or what caused it is another theme that you may get examined chemically if you wish. You have the material now so get the laboratoria working

saludos, Rein

P.S.

I will post a few Chilean examples of brown fibers today!

Hello

(About the last stamps : Transports : Horses, Boats, etc):

These definitive stamps appeared in May 1989 and were reprinted several times until October 1996.
They are 12 different designs.

I know them in 3 different papers and this is the order in which they appeared:

Novarode Paper (Belgium): Coated, very bright. Dull gum non-brightness. Fluorescent white intense.

Spanish Gummed Paper (Papel Engomado Español): Coated semi-gloss. Under UV: greyish

Harrison Paper (UK): Coated, semi-gloss (more than "Spanish" paper). Under UV: white greyish. This paper is like some Machin stamps paper from those years

Not all stamps exist in 3 papers. But most at least in two.

The easy way to differentiate Spanish and Harrison is by the gum.
In Harrison is white, smooth and shiny, and in "Spanish" it is semi-matte and under UV is mottled.

Best regards

Rein,
One of my magmifying glass is 8X and with ot i could hardly see teh brown fibers. Could it be that I am a daltonic?

Jorge,

the Novarode is a surprise! This Belgian firm did close down pretty soon afterwards and I need to find out exactly when! Where the paper mill was in Saint Genesiusrode they have just started building luxurous buldings!

saludos, Rein

The firm went broke in 1991!

Theoretically, fibers might be seen at spanish papers made at the "Fabrica Nacional de Papel" at Burgos
way up to 1992, roughly (until the third issue of the King), since by then, they changed "a few things" at the
paper mill, AFAIK. But I'm (still) not focusing in such modern issues (I'm screening stamps of the first issue of
S.M. el Rey and the previous one: in those definitive series, fibers could be seen, thats a fact!) My .02

PS: Jorge, could you explain a little bit that spanish paper you found on chilenean stamps?
