Help Needed Using Chinese "Chop" on DesignJet Papers

Here's one for the real afficonados.

I love using a hand carved chinese style stone seal "Chop" printing that
wonderful vermillion red "Dragon'd Blood" Cinnabar Ink Pasteto sign my
work....

On porous uncoated Chinese and Japanese papers it works great!

Unfortunately the chemistry of the coated DesignJet and Large Format Jet,
Iris, or "Giclee" style papers doesn't seem to jive very well with the
(Cinnabar Paste) Chinese Dragon's Blood Ink Paste.

I've tried thinning the "Dragon's Blood Ink Paste", with Linseed Oil, but
I'm still not getting 100 percent results......Perhaps another Thinning
Agent might work. BTW Where can I buy Castor Oil? Any suggestions?

Would an American Ink or Ink paste Work better on the Coated
DesignJet/InkJet paper?

Can Anyone out there suggest a solution or a work-around?.

Thanks!
