Mustafa the note Bob Hudyma sent you does have good information.
To find the information you want is very difficult . If we had the  
formulae and information
I think we'd be seeing the autochromes being manufactured. The  
equipment to press the starch
and make the image is rare and the closest product we know is the  
Fresson print made  by the
Fresson family in France.
Someone on this list also sent the information on the History of  
Photography journal article, which
is quite in depth with even color photographs of the machinery.
