Hi Chester,
I'll try and find the previous thread you speak of.
I did read something i found on a web sear about spraying ordinary paper with a silicon based water repellant and then as you state coating in a Dextrin solution, 'baked cornflour & water, via reduction'.
It's, a bit of a-long-winded process, but i might just try it, as the Xerox paper i have, and tried doesn't seem to leave enough toner @ 100%, and the Kodak glossy photo paper i have leave's behind a lot of residue 'don't know if this is a clay based', but end up rubbing the toner away in the attempt to remove the residue. The residue, when soaked does become translucent, but not enough for the FeC13 to do it's work.
Darren.
