I frequently print gum over platinum (as well as kallitype and palladium).
I have two approaches:
1) In printing from a B&W negative, I'll print about 90% of the image in
metal. Gum is used to enhance the print in subtle ways, similar to a
"duotone" or "tritone" mode in Photoshop. Fascinating effects can sometimes
be gained with using very small amounts of contrasting colors such as green
and red, each layer printed with a separate negative.
2) Printing with gum, I sometimes use a metal for the black component in a
CMYK process. The platinum or kallitype adds "punch" to the picture, but in
this instance, takes a back seat to the colors of the gum.

Subject: gum over platinum and the like
I am currently exploring ways of combination printing, like gum over
platinum, and I would like to ask whether there are other people practicing
such methods, and, above all, which effects, or artistic ends they try to
achieve.
Steichen tried, as far as I know, to get, among other things, color effects.
"Spirits of salts" mentions the shadows were emphasized in old platinum
prints by this method, and Heinrich Kuehn writes that tonal values can be
grouped together in a platinum image by placing a layer of gum over them
(for him, the richness of midtimes was something distracting, which
deserved to be counteracted).
What is it you are after? I ask this to get an idea of the artistic
possibilities such printing methods.
