Recently I borrowed the FACIT 2015 Special
catalogue from the Harry Sutherland Library
at the VGG Philatelic Research Foundation in Toronto.
It's a superb catalogue written in Swedish and
English which makes it easy to use.
I really should get myself a recent edition.
Engravers and designers are still listed but no printers.
I was interested in seeing what Facit
had to say
about various stamps we had been discussing over the years.
As far as the European Nature Conservation Year stamp is concerned
here is snipped from the catalogue. Facit
states that 6 colours were used , print was by Combination offset and steel engraving recess.
Paper was Ordinary with fluorescent overprint (Finnish)
The Swedish Stamp Printing Works didn't have a press like that in 1970.
The Bank of Finland Security Printing House had installed a 6 colour STIF press in the early 1960's
which could handle that.
This French built printing press printed 3 colours direct recess
and 3 colours indirect(offset)recess.
See previous thread about STIF http://goscf.com/t/37831
I believe now that the stamps were printed in Finland.
One thing still puzzles me though.G:
Cz Slania was the engraver but what is meant by line-etched photogravure (value numbers)
