Well, yes, that has been my experience. You can't be switching out
multiple sets of rollers and multiple inks on a Vandercook for one
print. Simple as that. And that is what is required. You would have to
dispense with the press's roller system altogether. A bit cumbersome to
adequately hand ink on a Vandercook. Which is not a problem so much as
the cylinder pressure is. Essentially, its single line pressure is
inadequate and its singular direction force will tend to rip the
collotype matrix off of its base. Not so good. You simply can't get the
kind of uniform pressure required as from an iron hand platen press.
The Kirby book basically sucks. Or blows. You pick. I can't image how
you would be able to produce a collotype based solely on that book. Or
trust the information given in it. We came to the conclusion that Kirby
had not done multiples and was basically one of those grant track folks.
There has been previous information posted here regarding the better
This is a very difficult process. I have done it (as part of the
editioning of a book), and am very appreciative of the experience (there
is none better for informing one about the variances of the printing
process), but I can state with some certainty, I would never ever do it
