Hola.
Hace un tiempo que tengo estos 2 sellos separados con dudas. Los subo al foro a ver si me echan una mano.
En primer lugar referente a la impresión de tinta negra.
Mis dudas:
- No me parece un "flujo" de tinta, similar a las próximas ediciones de flores.
- Es posible una duplicidad por vibración?.
- Es simplemente un arrastre de tinta?

Omar,



around 1977 the Casa de Moneda did use 2 main groups of paper for the definitives [cifras, cintas, historical buildings, san martin, etc] printed on the Goebel rotary photogravure press! Only for that press- no offset-litho!

- The "normal" coated paper which usually display a glossy surface
- the "modified" coated paper which has been coated but seems to have had a treatment with "papel de lija" afterwards onb purpose to make it less shiny/glossy or not all shiny!

Argentina calls the first paper "tizado" which can be subdivided according to the luminesce of front and back; the second paper is called "mate" but unlike previous matt papers it IS COATED and also that second type can be subdivided according to luminescence. The second paper is usually somewhat thicker and displays a rayado effect at the back; the paper mesh is asymmetrical.

No matter what paper used fort he stamps you showed us, there is NO DOUBLE IMPRESSION Argentinean philatelist are so keen of! Just the normal flow of ink in the preferential direction - some hardly noticeable some impressive, but NEVER a double print!

saludos, Rein
