Pre-shrink paper for gum (oa to Katherine)

The recent exchanges about gelatine sizeing and hardening made me wonder: as
I understood and employed sizing: when one does multiple gum prints, one has
to pre-shrink your paper (soak it in hot water and dry it. This
pre-shrinking results in loosing the size (gelatine or something else, not
always known). So one has to size and harden again.

Katherine: if I uderstand correctly from your webside you do not pre-shrink?
And you re-register by "selectively" dry your paper until your register
marks match. Do both dimensions shrink equally?

In my own limited experience I first faithfully shrank and resized, but
later I only shrunk and did not size, and I had no problems with multiple
layers of gumcoats..

So maybe I should also abandon pre-shrinking..

I found re-registering the biggest hurdle in multiple printing, subsequent
layers never completly matched..

Comments?

Best,
