I am sure you’ll
get expert feedback, but in my very limited experience: when working small
format (say 4*5) you can do without pre-shrink and sizing. On some papers you
can pre-shrink and not re-size.
This offcourse depends on
the paper and pigments you choose and should be tested. The concensus seesm to
be:pre-shrink, re-size and harden. But there are many variants on this route..you’ll
have to test them for your self, (be sure to take a look at the PF issue, link
posted earlier by Judy, that descibes a solid (perhaps fool proof) approach to
gum printing, using that route gave me instant results, which is very
gratifying when starting out)

Been following this. I've done a gum or two and am not encouraged
by the results. I'm interested in the whole sizing element. I know
many papers come already sized, but either the sizing is inadequate for gums or
it is lost in the shrinking process. When sizing, it's dipped into the
gelatin, then a seperate hardener bath? or hardener is mixed with the
gelatin solution?

PS to Jacek:
Often the best way to get a "black" in gum printing is to mix two or
more
colors... for a long time I mixed a Rowney gouache "jet black" with a
strong red. There are also complements that mixed together make
"black,"
or maybe something like burnt umber with indigo (which, depending on the
make and pigment of course, can have a lot of covering power).
