Rotogravure,Tiffdruck Inks used by National Geographic Analysis Reports, Source ?

[Mustafa Umut Sarac]

Hello everyone,

I started thinking serious about colors when I first started reading National Geographic Magazines at mid 80s. I want to read chemical and spectrophotometer analysises of these era inks. I am searching the google and it turns to me tragicomic results. I tried to contact with Rochester Institute of Technology but it turned empty. Can you give me a journal name or other resources to track down the reports ?

Thank you,

Mustafa contact their printer (NatGeo), they should be able to provide you with the ink mfg. and he in turn will be able to provide you with the required data.
Or try to get a copy of The Printing Ink Manual by R. H. Leach
Tiefdruck Rotogravure we're talking intaglio inks as opposed to litho or offset inks.

Good luck
