Running from bottom left to top right:
Running from bottom right to top left:
Most significant however is the fact that the yellow line runs horizontally!
Compare with the 1923 version:

This second version has the readable text visible from the BACK of the stamp - single stamp- but visible from the FRONT - block of 4!!!
Can we tell the felt or wire side???

Both with readable text and visible from the back of the stamps, both issued in the 1940-ies...

Rein, Does it mean that two Dandy Roll were made? One with horizontal alignment y the another one with vertical alignment?

I should make this more clear in the Facebook pages!
Arturo may have more information though, but so far I have not seen the detailed listing of his 6 different types of paper....

The TIEV is supposed to have 10 Waite&Saville printing machines! Four of which we can see on the photograph!
They are also supposed to be die stamping recess AND reel-fed. The latter is clearly visible on this photo....

There must have been at least TWO types of the Waite & Saville presses!
The ones that stamp a block of 30 [50] stamps one after the other and in the mean time using a box-perforator to perforate the sheet in one stroke!
This process was in use for monocoloured stamps in the 1934-1960 [?] period. The type of perforation did only start in 1934! But the printing by die stamping could have started earlier.

The 1950 definitives still had this type of perforations and dies!
Not only a sideways shift but a vertical shift!
The watermark is the MEX-MEX one, in use after 1953.

But how about the multicoloured stamps???
Quite a few in two colours - mainly the high values - and ONE stamp in three colours.
The red bars are in typography and the number may be an order number!
This type of bars was common for multicoloured stamps, but also another type of margin prints did show up!
Bear in mind that the monocoloured had NO margin prints whatsoever but for the sheet-counting!

The bars still with the 20p and MEX-MEX watermark;

The other type of margin was already there in 1944!
Maquina PW-9 suggests that it was printed on the Prensa Waite number 9 [out of 10!]
Thanks to filatemusico [José Leal] for the pictures!

The new type of margins!
Printed on the PW-9??? Take note of the sheet number on the left margin! Watermark "Gobierno Mexicano".... I.e. the 1950-1952 period. Box-perforation.

The guilloche printing is most likely in screened photogravure! I will show a similar one of the 20p aereo.
