Yes always. The saunders is a rather porous paper and stains easily, so
must be sized. I use 2 coats of a 3% gelatin size with formalin added to
the 2nd bath.

A little of all of these. I use a range of colours in my prints and like
the contrast and detail that builds up over more than 4 coats. Usually
6-8 coats is fine, but I have been known to go up to 12 coats. Depends on
the image and how I am feeling about the progression of the image.. Some
people think I go to far, but the trick is to do a few coats well
exposed, and then more coats less exposed..

I really don't have an answer to this as firstly I don't use black
pigment, and secondly I haven't done mono gum prints...
