All,
I am also a member of the CarbonTransfer group, and recently Sandy King came up with a document about setting up an "all gray ink set". An ink set where where the inks are, K=PK, C=PK, M=PK, Y=PK, LC=PK, LM=PK, LK=LK, and LLK=LK. He uses this method to obtain nice digital negatives on Pictorico OHP.
Not so long ago I also discovered another manual from Mr Michael P. Rosenberg. In his manual (Digital Negatives for Silver Gelatin Prints and Alternative Processes) he describes how to obtain digital "negatives" for printing traditional silver gelatin prints. In fact his negatives are different then the one above. He uses Glossy Photo Paper as the negative media. Today I wrote him, and asked if his approach would work with an "all gray ink set" as described above. He answered yes.
With the help of Mr Paul Roark and Mr Ernst Dinkla I developped a custom, diluted ink set based on HP Vivera PK. (K=PK, C=30%PK, LC=9%PK, M=18%PK, LM=6%PK, Y=2%PK). I use this inkset to print on cotton rag papers.
The tool for all 3 processes is QTR.
Now, I am wondering if it would be possible to use an "all gray ink set" (K=PK, C=PK, M=PK, Y=PK, LC=PK, LM=PK, LK=LK, and LLK=LK) for printing on rag and baryta papers??
Best regards,
Ben Albu

K=PK, C=PK, M=PK, Y=PK, LC=PK, LM=PK, LK=LK, and LLK=LK
is a whole lot of PKs for printing a direct photo on paper. I think you'd be happier with more LKs and LLKs.
It definitely works to have a setup with, for matte, K = MK, then C & M = PK, and LC & LM = LK. Y can be LK or LLK. Basically that is what UT14 is, but with the C channel being a cooled carbon and M channel being 100% carbon.
For glossy, I'd favor K = PK, C & M = LK, LC, LM, and Y = LLK.
HP's Vivera is cooler than the Epson K3 versions. MIS's K4 grays are 100% carbon and warm.
FWIW,
Paul
