CD publishing is the use of CD duplication systems to create a large number of unique discs.
For instance, storing a unique serial number on each copy of a software application disc would be considered CD publishing.
The term CD publishing is believed to have been coined by the Rimage Corporation as part of a marketing program which referred to CD-R discs as "digital paper."
Automated disc production and printing systems, such as those made by Rimage, can be shared on a computer network much like an office printer to facilitate the creation of unique discs.
This is the root of both the digital paper and CD publishing terms.
