All about the 10p Puente del Inca

[Rein]

A lot has been written here about the papers and colour shades of the 10c Puente del inca, but nothing about the 10p Puente del Inca!

Is it such a boring stamp????

See Holler first!

Looking at Solari - "Parecen Iguales son diferentes"



Just 3 versions for the photogravure! Thick and thin paper???

Finding two of the same characteristics would have made me thought to have a real plate flaw. What I have seen in the other definitives of this period makes me wonder! Particularly studying the 3p and 5p that also have both directions of printing for the lengthwise printing!

Tne 10p shows both U[pwards flowing ink] and D[ownwards flowing ink] that ponts to a tête-bêche lay-out for the printing sheets!

The 10p Puente del Inca had at least TWO printing cylinders!

The first cylinder had - when seen with the axis lying as if watching from the front outside the press whiel the paper reel was moving towards you - two panes of 10x10 next to each other. The left pane has the direction of printing U [p] and the right pane has D [own].

The multipositive film comprised 10x10 stamp images and was used for BOTH panes! This can be shown thanks to multipostive film flaws that occur together with plate flaws that are specific for a pane!!!!!

Two stamps from the left pane:



Three stamps from the right pane:

Three stamps from the right pane:













The dot above "D" is a film flaw and so is the dot in the "E"!

The cylinder with two tête-bêche panes was predominantly used in combination with the uncoated Zárate paper, symmetrical paper wire structure and the direction of paper vertical! Not just the "normal" stamps but also the S.OFICIAL stamps were printed using the same cylinder plus a black colour cylinder!

It is that black colour cylinder that turns out to have a peculiar flaw!! A feather!

So far we haven't had a look at Bardi's book:



ZA 2 and ZA4 are just two names for the same paper! At least here as none is whiter than the other. The difference is in the orietation of the watermark: ZA2 has the line of AЯ parallel to the short side of the stamp, ZA 4 parallel to the long side of the stamp.

ZA 5 is not to be expected, but if so then with the line of AЯ parallel to the long side of the stamp i.e "M" in terms of Bardi and not "m".

Just as with the other recently discussed definitives in photogravure the coated Zárate paper is most common with the line of AЯ parallel to the long side. Copies with the line of AЯ parallel to the short side of the stamp are far from common.

The early printings on uncoated paper had a direction of printing of either U[p] or D[own] depending on the position on the cylinder! The left pane had U, the right pane D. The multi-positive film of 10x10 was used for both panes and some characteristics can be traced back to the film.

Later printings [1965?] were on uncoated first and later on coated paper using a new printing cylinder of 2x10x10 stamp images. This time the long side of the stamp run parallel to the axis of the cylinder. Direction of printing always L[eft] so there was no tête-bêche lay-out

This new cylinder can be easily recognized as it predominantly was printed on coated paper! The direction of paper is mostly horizontal as is the case of many values in the P&R II series. A vertical direction of paper is rather scarce! Bardi's 5.00 is too moderate - certainly when we take into account the quality condition of the stamp.

A rather impressive multi-positive flaw is the one shown below!

A rather impressive multi-positive flaw is the one shown below! BUT - this is his twin brother on the other pane!

We do not know which one is on the left pane or on the right pane!

The uncoated paper version is most problematic! The direction of printing is not clear!

Should it have been U or D then we need to take as a starting point the multi-positive film. But that film does NOT have all the minor dots! And the stamp on uncoated paper DOES have all the minor dots - as we have both on the coated paper and the uncoated paper for at least ONE pane!
