Digital BW, The Print

I got a reply back from MIS. Mathew at MIS says that the ink and base will mix OK but also confirms what both Homer and Paul say about color shift and does not recommend using it.

Homer,thanks for the recommendations.I like semi gloss prints and would still like to use the R260 printer (same inks as 1400 but different carts). Will the UT-14 ink set work with it and QTR? or is it just for the 1400?

Paul, thanks for the heads up on 2K-2LK not being for beginners.
I read your PDF on mixing the Carbon-6. Are the percentages based on weight or volume? I still have my Ohaus beam balance from my darkroom days so mixing by weight might be more accurate for me.
Cost isn't a big issue at present but I will be retiring in a few months and expenses could become an issue in the future. Just need to keep all my options open.

Thanks to both of you for steering me in the right direction.
