When making colorized (spectral) digital negatives, one color does not fit all. For achieving a full range of tones with good separation, it is critical to match the color to the chosen process and individual workflow, especially for carbon prints. Dan's work with digital negatives was groundbreaking -- I took a digital neg workshop from him about 12 years ago -- but unless he has changed his procedures, PDN or RNP arrays will probably yield a better negative. PDN is a structured approach that can yield results quickly, and the manual alone is worth the price as it's a well-written and fairly comprehensive discussion of digital negatives.
Making good digital negatives is still not a trivial undertaking, and choosing the wrong printer will doom you from the start. Trying to learn digital negative and carbon transfer basics at the same time is exponentially more difficult since there are so many variables at play. A workshop for one or both would be a good plan. Using Bostick & Sullivan carbon tissue instead of homemade, and using supports that don't need to be sized (like RC and fiber photo paper or Yupo) will eliminate a lot of complexity when learning carbon basics. Good luck!
