Coated papers - papel tizado

The coated papers have always been problematic for various reasons. One - the coating it self being an obstacle in seeing the structure of the wire and the design of the watermark, two - not always having the certainty that the paper had been coated.

The old philatelist tool - the silver coin that is leaving black traces on chalky paper - may seem to work but is also a destructive method diminishing the value of the stamp. I would prefer not to use it at all.

Paper can get a more smooth surface by calandering - rubbing the paper by means of cylinders and thus improving the printing quality of the surface. This is called satinado in Spanish and there is no applying of an extra layer or coating involved...

Applying an extra layer usually gets done apart from the very paper making itself. It can be done much later in a completely different environment.

The Argentina stamp papers with a coating that had been used for the P&R I series have all been made abroad - so only the imported papers will have it. Since 1963 the papers made by the Zárate paper mills got coated and this had been done by a specialized firm elsewhere in Argentina!

Pettigiani recognizes 4 groups of coated paper:

J - a combination of 3 [?] types of imported paper that all have an orthogonal watermark but cannot always be split up or assigned to a particular subtype. For collectors who may get frustrated the overall "J" has been defined.

K - rayado vertical of English origin like the uncoated type of paper! But coated now!

L - Tela, also of English origin like the uncoated type of paper! But coated now!

M - Delgado, the very thin paper that was thought to be impossible! Also of English origin.

J combines 3 types according to Pettigiani:

JA - the paper, problaby of Dutch origin, that is reminescent of the other two papers of alleged Dutch origin - C and D - as to the design of the watermark.

It has been used for the 1939 UPU Congress stamps a.o.

As to the P&R I stamps: NOT the 1c Sarmiento!, but for the 5c Moreno and the 10c Rivadavia!

This can only be a mistake! Not reading Leopoldo Tenorio Casal OR disagreeing with him and then coming up with good arguments! The fact the Eduardo Williams has studied thousands of stamps does not consist one. It is the quality that counts not the quantity! I have heard this reasoning being used against me several times here in the Foro!

JB - the USA paper that combines both the rayado and the granulado!

It is supposed to have started in 1939 for the 5c Moreno and the 10c Rivadavia.

As with watermark type IV it should look like paper types G, JC and M! We'll see....

Apart from these 5c and 10c it should also have been used for the 1c Sarmiento and the 5c San Martin [1945]. Not forgetting the 30c Lanas, the 1p sin limites, the 2p Frutas and the 20p Cotton. The reference point for the commemoratives are the 1943 June Revolution stamps....

There are a few more stamps with this type of paper - Airmails - but the picture is clear.

The watermark is orthogonal, the paper mesh is symmetrical [!] but not with the usual density of about 30/20 but with 30/16!!!!! It could have been assigned - wrongly - a special type of Trama like the Tela [having the 24/20 density].

the 1939 5c and 10 have nothing to do with it!

to be continued ....

[Rein]

The 30c Lanas printed on coated paper with an orthogonal watermark, asymmetrical paper mesh, mesh gauge 30/16 [!], paper direction parallel to the long side of the stamp = "M", the type of paper introduced in 1943 for the stamps commemorated the 4th of June 1943 Revolution. It has to be studied whether the definitives got printed before or after that "glorious" event???










when you count the horizontal - in this picture - lines you will come up at 16 per cm!

30c:




50c:




This type of paper had been used in 1943 for the 4th of June Revolution stamps (all face values, the 5c however also exists on other types of paper).

The coating looks very peculiar as you can see the pattern of the wire from the front of the stamp!

The 1c Sarmiento:










This is NOT a rayado!

to be continued....

[Rein]

Neither are they!




to be continued ...

[Rein]

I shall leave the 10c Rivadavia for the moment as there is the complication with the various types Pettigiani recognizes!

And so far it should be clear from the pictures that the JB - or the USA 1943 stamp paper has nothing to do with the asymmetrical types - even though we can have very clear horizontal lines!!!!! And that is easily to be confused with the JC to be discussed later on....

Leopoldo Tenorio Casal


Finding relevant information, publications on the Argentine postage stamps is extremely difficult for someone who is not living there!

Being there and most likely having access to the philatelic libraries, some publications however not always quite agreeable with what you have in mind should be at least mentioned and contradicted if necessary. Just ignoring as was the case with Dario bardi publications is not fair.

Reading the 1947 article of Leopoldo Tenorio Casal, we find a reference to a first production of coated paper for the 5c Moreno and the 10c Rivadavia of 1939; a 3rd production however for the 1943 printing on coated paper for the 1c DF Sarmiento, the 5c Moreno and the 10c Rivadavia.

1c, third production:

25.05.1943 10 1.2mm, 30.8 x 17.omm



5c, 1st and 3rd production:

05.04.1939 10mm, 29.7 x 16.8mm



06.09.1943 10 1/2mm, 30.8 x 17.0mm




10c, 1st and 3rd production:

04.11.1939 10mm, 29.7 x 16.8mm
20.06.1943 10 1/2mm, 30.8 x 17.0mm




Where is the 2nd production!??? Where are the 1941 based examples of JC???

We find the following commemoratives having coated paper in the 1939-1943 period:

1939 01.04 XIth UPU Congress with an orthogonal watermark, symmetrical paper mesh, coating and/or varnish, in photogravure

but this is even before the 1st production of the 5c!

Furthermore:

1941 19.10 Julio A. Roca with an orthogonal watermark, symmetrical paper mesh, coating and/or varnish, in photogravure

This will be our second production!

1939 11.12 Fonopostal ortho - symm c/v photogravure

c/v coated and/or varnished

Thank you for all your time explaining this topic!!

JC - Rayado Horizontal

In two parts:

1941 for the 1c Sarmiento and 5c Moreno

and in

1950 for the 10c Rivadavia and 20c Torito

As I stated in my previous posting there was no 1941 printing order - believing Tenorio Casal of course - and if there was it would be great to have the Casa de Moneda evidence

Taking as Pettigiani does the 20c Torito as our crown witness I will provide some scans soon!

On page 51 of the Manual:





This is supposed to deal with the Rayado Horizontal! But the picture is of a symmetrical paper mesh!

This is a granulado!
