As far as I know the Italian
rotocalco translates
as gravure,rotogravure, photogravure, heliogravure which are all
relief printing but are definitely not line engraving, recess engraving, steel engraving,intaglio,Taille-douce or Calcography.
Florian explains it all perfectly in his post above.
That excellent article by Glenn Morgan
https://www.ohiogt.com/doc/articles...ts%201-3.pdf which KuoLC5310 has
provided a link to is all about gravure/photogravure not recess engraving.
This is what Glenn writes at the beginning of the article.
Quote:
To set the scene it is important to first
explain the basics of gravure (known
in America as 'rotogravure', in France
as 'héliogravure' and in Germany as
'rastertiefdruck'). At one time, collectors
only encountered stamps that employed
a photographic process in manufacturing
the cylinders, hence the frequently
encountered term 'photogravure',
but with the advent of electronically engraved
cylinders there was a need to differentiate,
as photography increasingly ceased to play
a part in the stamp cylinder manufacturing
process from the early 1990s.
I believe that these recent Italian engraved stamps
are still done by engravers but with aid of computers.
The transfer from the die to the plate is also computerized.
But they are still engraved which is a plus.
I agree 100% with

I guess the cold, robotic look is intentional.
I would add that they look lifeless and why are they predominantly
printed in black?
