With all the troubles associated with cyanotype print quality and
supposedly Ferric ammonium citrate, is it possible that someone has
information on the manufacture of blueprint paper once used for technical
drawings before plan printers and photocopiers came along?

As an old bloke, I can recall the ease and consistency of results of
blueprints from my own high school Tech.Drawing classes in the 50s.
As a teacher of photography in the high school situation, I use cyanotype
as just another technique and would be pleased to be able to use an
inexpensive ready made paper.
