RE: Newbie Gum fun Continued

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).
