Hi everyone, This is my first post at APUG, I hope I've picked the relevant forum for this question. Having just read Tim Rudman's book on lith printing, I'm inspired to try it. I wonder if anyone has knowledge to share with respect to toning lith prints with platinum and/or palladium. Is it possible? If so what colour changes are likley and where/how does one obtain the toner. Does the print tke on the archival properties of the toner? Thanks for any help in advance. Regards, Dave.
