Hi Erik,
Now I understand. For that application you essentially want a scene-referred rendering, which can be (mostly) accomplished with
Brightness 0
Contrast 0
Blacks 0
Point Curve = Linear
You would also probably need to build a different color profile. (The "Adobe Standard" ones, for example, have color mappings intended for general photography rather than scene-referred reproduction.)
Ideally for repro work you would build the color profile using training data drawn from the stimuli / materials that you intend to photograph. (e.g., for artwork you would want to optimize the color matrix based on the representative pigments, oils, etc. of the art that you intend to photograph). I mention this because this is quite different from using training data for general-purpose photography (e.g., skin tones, sky, grass, etc.)
