There is hardly any knowledge available on the 22p Industry! Let's see Holler first!
The photogravure version issued on 31.10.1962 and the offset-litho version someday in 1964.... |
|
Bardi's book recognizes a few more versions of the 22p!
Just two versions of the photogravure stamp whereas I can show at least 3 versions! The ZA 2 and the ZA 5 are more or less equally present in numbers in my collection... |
|
ZA 2 [or ZA 4] has an orthogonal watermark with a symmetrical paper wire structure whereas ZA 5 has an asymmetrical paper wire structure. Bardi just refers to the ZA 2 version with the line of A horizontally, whereas both horizontal and vertical occur! Apart from this the density may differ!
The latter version has not yet been mentioned .... |
|
Bardi's ZA 5:
Orthogonal watermark, asymmetrical paper wire structure and horizontal direction of paper.... Plus continuous long lines!!! |
|
So far only one and the same direction of printing has been established: L [eft ink flow] for all types of paper. "Plate flaws", the few I saw occur also on all types of paper accordingly assuming there was just one cyilnder! ZA 2:
ZA 5:
