Hi Loris,

Sullivan & Weese wrote a short section of several paragraphs in their book
The New Platinum Print covering the use of gold with Ziatype printing. You
may find the last two sentences in the section a useful guide for using
sodium tungstate and gold additives.

"Tungstate and gold also get along well. The increased contrast of a 30%
gold Ziatype can be compensated for by several drops of tungstate, with a
resulting gun-metal blue/green/gray color that, while perhaps not to
everyone's taste, may be perfect for some subjects and certainly looks

As for split toned ziatypes, it has been my experience that cesium palladium
solution used with sodium ferric oxalate will yield split tones and add some
contrast (AFO will split also). I have never gotten split tones when using
lithium palladium solution and gold alone. BTW, you can't mix gold chloride
with cesium palladium, as noted in TNPP, "...but a drop of gold added to
CsPd results in a small puddle of expensive mud."

Also from the TNPP, a 50-50 combination of CsPd and LiPd will produce split
tones with warm midtones and highlights with neutral DMAX. And that has been
my experience.

Even though the ziatype process is a POP process I normally print by time
not by inspection. Each time you open the back of your contact printer the
humidity of the print will change causing the printing characteristics of
the drop mix to change. I use a mylar sheet behind the paper to aid as a
vapor barrier to help trap the humidity of the paper in the contact printer.

You can also make POP platinum and palladium prints with the standard
palladium and platinum solutions when used with AFO. Platinum is a great
additive to use with LiPd to modify contrast and tonal structure of the

The ziatype process is very flexible, like a piece of plastic; good ziatype
printing requires a fair amount of practice and experimentation to be able
to produce predictable results. Once you start you may be hooked! If you
plan to continue printing ziatypes TNPP is a worth while book to have.

My 2 cents,
