Kodak H-387 (Digital LAD, 2011) defines printing density as 0.002 x 10-bit code value with the digital LAD patch at code value 685 = printing density 1.370, states those are printing (not Status M) densities, and also tabulates the corresponding Status M values for the recorded intermediate stock.

Curator qualifications: Cineon draft, scanning recommendations, ADX CTL and DPX statements (E2-E8) not reinspected. Status M columns apply to the named recording stocks/tables, not as a general conversion.

Limitations: One Kodak guide.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
