I interviewed him for one of my books some years ago. He used half tone
negs produced by Herzig Somerville (sp?), a high-end Ontario offset
printer. I seem to recall however that he used pigments used in offset inks
and claimed that the prints would therefore be permanent. This is a common
mistake that many people have made over the years. 99.99% of all
commercially available offset 4-color ink sets are NOT permanent...
If you want "gum prints" that look like conventional photographs, the
UltraStable process on a regular support will do the trick. It will also be
easier to use and much more permanent.
