I have posted on my web site a monograph detailing my method for making digital negatives for silver gelatin prints. This is an adaptation of Ron Reeders method of making QTR profiles. In the monograph I describe how to make single curve ink profiles that yield a linear curve corresponding to monitor %K values. I also describe how to make black adjustment curves, correction curves, and combination adjustment and correction curves. These profiles result in darkroom prints indistinguishable from traditional projection negative prints, and exhibit fine grain and smooth tonality transitions. The monograph is in the form of a PDF that can be downloaded and saved.
I am unable to post the profiles, curves, and grayscale target, for download on my website (due to the host restrictions on files), but will e-mail them to any interested. The grayscale target incorporates additional gray steps for those interested in using Ralph Lambrechts or Huntington Witherill's spreadsheets to make correction curves, as well as Zone System scale for visual calibration.
The ink profiles that I describe may also be of interest to people using alternative processes.
