Well, here is the e mail I sent:
"Recently it came to my attention that you were marketing "Carbon" digital prints. I find this description misleading and deceitful for the following reasons:
The term Carbon print has been used for more than 100 years to denote a print in which pigment is suspended in gelatin and the gelatin is then coated into paper, which then is sensitized to UV light by adding a sensitizer like potassium or ammonium dichromate. These prints can take up to a day to make a single print since they require many processing steps.
The resulting print not only has an ecxeptional durability but the print itself has some relief depending on the final support paper, something I am sure your ink jet prints do not have.
If you were making a digital negative which then was printed with the real carbon process, I would accept your description of "Carbon digital print," but presently your prints are nothing more than ink jet prints using carbon based inks, which is an entirely different thing.
Furthermore, in my research of these inks, be they Ultrachorme, Piezography or MIS it is my beleif that the actual "black" ink is the least stable as it requires dyes to make it "really" black. The grays are more stable as they mostly composed of carbon pigments. So I beleive your description in the web site is also inaccurate. In additon accelerated test are only and indication that the inks could possibly last 100 years, they are not by any means proof that they do so. I beleive you actually were victim of these accelerated test with your RC prints which you had to re make since the claims made of their durability were not real.
As an alternative printer I am dissapointed to see such a fine photographer as yourself using these misleadign marketing tactics to promote something that in and of itself you should not be ashamed of. I am sure they are fine and beautiful prints, but they are not carbon prints by any means.
Furthermore, I hope that any of your collectors does not come across a real carbon print, since he/she will notice the difference and will understandably be upset, perhaps demanding a real carbon print or a refund of their money. "
So why dont you invite him David, I dont want to make a nuisance of myself
