No Mark this is not another name for collotype
You have had a bit of a rough ride on this subject so far nobody seems
interested
I think this is because you need a printing press geared to this kind of
printmaking lots of bucks!.
I have in the past done some collotype print making, my printing press was
an old domestic mangle used to wring out clothes, I sheathed the the
rollers in steel pipe and bingo an instant printing press, unfortunately
this great printmaking machine did not like glass plates the preferred
substrate, and I had a cracking time until I cameto my senses, so I decided
to go onto aluminium sheets which worked quite well.Also anther substrate,
which was very efficient was fixed out film on ester base, the fix was
none, acid hardening, ie pure sod thiosulphite. I gave up in the end as
the process was so time consuming , but I can understand your obsession .
