PQ codes tell a CD player where each track and sub-index starts and stops, and are accurate to the CD frame, which is 1/75th of a second. From these PQ codes a cue sheet is generated - this is the track list that is formatted so track times are listed relative to the beginning of the CD.

This is the preferred format for CD replication houses.

Upon mastering your CD, Nova Sound Laboratories will provide you with a cue sheet to take to a CD replication house of your choice to begin bulk duplication.
