And the Rein´s brain, which is magic and very clever!

Rein,

What do you think it is the best approach? The main division in PyRI is offset vs typo? or with/without watermark? or mate vs clay?

Alejandro,

the main division is offset-litho vs typography; second is uncoated [matt] vs coated [clay, tizado]

then the hard stuff: establishing the axis (direction of paper) / eje de enrollamiento AND establishing the paper wire - blue lines symmetrical vs blue lines asymmetrical ...

and further: the line of AЯ perpendicular to the axis [=orthogonal watermark] vs parallel to the axis [=parallel watermark]

Matt - MI 1, MI 2 MI 3, MI 4, MI 5, MI 6, MI 7, SF 1/2, SF 3, ZA 1, ZA 2 , ZA 3, ZA 4
Symmetrical - MI 1, MI 4 ; MI 2, MI 3, MI 7, SF 1/2, SF 3, ZA 2, ZA 4
Parallel - MI 1, MI 4 (the difference between them two is the density! MI 1 has 30/20, MI 4 has 24/22)
Orthogonal - MI 2, MI 3 = MI 7 [disputable]; ZA 2 = ZA 4 [disputable]
Diameter - MI 2, ZA 2 [8.5mm], MI 3 [10mm]

how to differentiate MI 2 and ZA 2? Timewise! MI 2 = 1937-1938, ZA 2 = 1954-1959; quite often (assumedly) no watermarks appear to be ZA! Practically all of them ARE produced in Zárate!!!! The Zárate papers have rough surfaces of the front - lots of grooves! MI 2 (Austriaco) has a heart-to heart distance of 16mm (instead of 17.5mm)....

Matt - MI 1, MI 2 MI 3, MI 4, MI 5, MI 6, MI 7, SF 1/2, SF 3, ZA 1, ZA 2 , ZA 3, ZA 4
Asymmetrical - MI 5, MI 6, ZA 1 = ZA 3 [disputable]
Parallel - MI 5
Orthogonal - MI 6, ZA 1
Diameter - MI 6 [10mm], ZA 1 (8.5mm)

Coated - TI 1, TI 2, TI 3, TI 4, TI 5, TI 6
Symmetrical - TI 1, TI 2, TI 4
Parallel - TI 1, TI 2, TI 4 (the difference between them is the density - TI 1 has 30/20, TI 2 has 30/16 and TI 4 has 24/22)

Coated - TI 1, TI 2, TI 3, TI 4, TI 5, TI 6
Asymmetrical - TI 3, TI 5, TI 6
Parallel - TI 3
Orthogonal - TI 5, TI 6 [the difference is in the thickness; TI 6 is very smooth and thin (delgado)]

THIS should do for the time being!!!!!!

In the first number of the Revista de la SofiA of January-February 1941 the freshly issued French y Berutti stamp was described and this article contains a lot of useful information:





Particularly interesting is the part where the printing sheet was described!



A printing sheet [pliego] consists of 2 [counter] sheets [planchas] of 10x10! Each counter sheet had been build up by reproducing a root block [grupo raiz] of 2x5!

The blanc space between the two panes [counter sheets] is 30.5mm, meaning that the two sheets were positioned on top of each other!

We already knew that this type of root block had been used to build up the large sized P&R I stamps like the 20c Toro, 25c Labrador, etc..

Reconstructions of these root blocks can be found here in the Foro!

We have to dig deeper in history to find more interesting stuff- May / August 1933:








I will resume this in the 1928 Airmails thread!

We have to dig deeper in history to find great stuff -1933:





I will resume the discussion of this second article as well in the 1928 Airmails thread! And in the 1923-1924 JSM threads!

We have to dig deeper in history to find great stuff -1928?:



What is written here about the 36c is NOT conform what Leopoldo Tenorio Casal had written in his 1933 article!!! Acccording to him there was no Dutch paper used for the 36c!

Very interesting articles! I wish to see PyRI's...

Alejandro,


there aren't that many I have, see the AFRA's:
