Postal services 1978

[Rein]

The 1978 "Difusion de servicios" definitives consist of 3 values: 20p, 30p and 50p and were printed supposedly in photogravure. The types of paper used have also luminescence substances in the coating as mentioned in the catalogue. But that is not the most important thing about this issue.

The later printings seem to have a rather pecular type of photogravure - or maybe it is offset-litho - that shows a very irregular corn instead of a regular photogravure screen. It is also much too early to see the electro-mechanical engraved printing that only started in 1982 with Belgian stamps! When you give it a good look you may see a regular screen in the middle of the printed, coloured field, but the edges are so irregular! Any suggestion of what this is very welcome.


This definitive issue is not the last Argentinian definitive issue that has this type of screens. I will return to them later. I get the impression that these variants are completely overlooked by the Argentinian philatelists...







and in detail:

The 20pesos is still in the tradtional photogravure! That is this printing ....



The 30pesos and 50pesos have the irregular screen ...

The 1978 Postal Code defintives comes in several papers and printing methods.

I would like to show a few ditties that at first sight may have been fly specks but on second thought seeing 3 of them made me think twice:

The blue 20 pesos stamp also exist in the coarse photogravure version:

In 1978 short set Postal Services the new type of photogravure printing [etching??) shows 2 different cylinders judging by the screen gauge: 70 lines/cm instead of 100 lines/cm as the 2 other values have.

Subject: Serie Turismo - Tipos de Salpicados

Hola, quienes clasificaron la serie de Turismo y lo hizo teniendo en mano el libro de Guillermo Solari "Parecen iguales pero son diferentes" se habra topado con lo siguiente:




Vemos que en la anteultima columna aparecen los términos ESTRELLADO, SALPICADO y RAYADO, estos tres se refieren a tipos de salpicados. O sea, a lo que se ve exponiendo el sello a la lámpara UV. Es mas simple de lo que yo creia, espero que les sirva el dato, yo no lo sabía
