The final, composite (dialogue, music and sound effects recorded together) mix of a film that can be transferred directly to a track negative or a mag stripe print with no further changes in level or equalization.

If noise reduction is used on a printmaster, it most often matches that of the final print format, and thus can be transferred stretched to the mag stripe print or track negative.

In the case of a stereo optical film, the printmaster contains two tracks, Lt and Rt, that are transferred directly to an optical sound negative.
