Nze is not after the dusting-on process, but rather trying to follow some
of the documented conjecture about how Artique manufactured his printing
papers. In brief, it is written in several different books that Artique
would take a colloid coated paper and place it in a dusting box to add the
final pigment layer. Artique printing was the process that Fresson
modeled his process upon. Accounts indicate that Theodore Fresson
improved upon the Artique Process with paper that was more consistent and
provided more reliable results than Artique. The Artique's took there
secrets to the grave.
