Hola
Estaba chusmeando en un sitio de ventas, y encontré esto: Lo anuncian como pruebas no adoptadas.
No es algo que me interese, pero me llamó la atención. ¿Son buenos?

Saludos

The Nederlandsche Rotogravure Maatschappij had been active in preparing photogravure stamps both with and without screen. They were in close cooperation with the German printing press manufacturers Goebel AG in Darmstadt. I would not be suprised that these stamps - very similar to the ones I have in the NRM archives in Leiden, The Netherlands, originate from the period round 1930. The photogravure stamps without screen were to be nearly identical to recess-printed stamps. GOEBEL was also responsible for the press with which the first stamps were printed in photogravure by the State Printing Works in Rome.... And the first photogravure stamps for South Africa!!

The German word "muster" also points out to the German machine manufacturer...

Adjunto una de las pruebas con filigrana hecha en el año 1932? por el Instituto Poligrafo dello Stato en Roma.

Martin, VK dice que existen pruebas de dos empresas: 1) Insituto Poligrafico de Roma y 2) de Harrison & Sons. Supongo que estas muestras impresas en offset tienen su origen en Roma, el sello con filigrana que parece grabado entonces seria un producto de Harrison. Ambos deben haber aparecidos en los anos 30 y probablemente sirvieron como muestras, quiza impresas por Göbel, para fomentar las ventas. Un cordial saludo,

René

Having the brown stamps myself now I can clearly they are printed in the secret method of the NRM - photogravure without a screen - the poor man's recess! The diagonal lines in the corners are typical for that process - see all the South African unscreened photogravure stamps of the 1930-1948 period.

There is no offset involved as Rene Jacobsohn suggests!

GOOGLE:

Tener los sellos marrón yo ahora noto claramente que se imprimen en el método secreto del NRM - fotograbado sin pantalla - el grabado de los pobres! Las líneas diagonales en las esquinas son típicas de ese proceso - ver todos los Estados de África del Sur sellos fotograbado sin pantalla del período 1930-1948.

No hay offset como René Jacobsohn sugiere!

Hola

Rein es EL especialista para los diferentes metodos de impresion. Yo no lo soy y creo que Rein tiene razon. Los que se interesan al tema pueden informarse en el VK58, capitulo pruebas. Hay una pequena diferencia de tamano entre estas
muestras impresas para Harrison y el Instituto Poligrafico, tambien hay mas colores que las mostradas. Saludos,

René
