RE: Third party inks for negative printing

[Eric Neilsen <ejnphoto@sbcglobal.net>]

Kees, Have you tried limiting the black ink with QTR? It seems odd to me
that you can't use any. I have not used those inks, but I'd think that
rather than turn it off completely, one might be able to add a little. 

As for smearing with matte black, I have been spraying those made with MK to
prevent that.
