600 units seems to give me the best blacks and the first white at 75.
This is the print made with the starter curve exorted from the QuadToneProFiler-QuickCurve-DN_v1,2_carbon_1_29_18.xlsm worksheet
The white - 0 looks great and seems to have no problem blocking. The blacks are deep and consistent with the QCDN-Blocking-Density-Curve-8-ink print. Everything else seems too dark.
This is as close to what I want as I can get right now using QTR and the profile Carbon_Nu_bone_5_curve_lin_11_12.qidf based off of Sandy Kings carbon100 profile, but the blacks are weak.
The link below is a zip file with the jpgs, Excel sheet - QuadToneProFiler-QuickCurve-DN_v1,2_carbon_1_29_18 and profiles used.
