Spotting Pt/Pd prints

[Andrew ren]

Got back to Pt/pd printing session recently.
no matter how careful I am, always got some dusts on the glass of nuarc, the pictorico, then they will all show up on the prints...
any suggestions which chemical i should use for spotting?

Cheers

Diluted watercolors. Dick Arentz recommends burnt umber, ivory black & titanium white.

Only thing to add - use a VERY fine brush and proceed very carefully. The papers used in Pt/Pd printing are far more absorbent than ordinary silver papers, and respond far more 'vigorously' to spotting. Use a very gentle hand.

Thanks hmf and Louie!

You may occasionally experience a black spot/stain area that needs to be removed. Mutamsky's method, as described on page 101 of Arentz book, is very effective.

Doug,
thanks for the input.
looks like I have to get a copy of that!

Depending upon the tone of your prints the warm-tone spotting pens can work and so can pencil.

I go the watercolor route, but I have successfully used both of the above before.
