Re: [ARSCLIST] Fw: [ARSCLIST] Gold CDs

[Steven Smolian <smolians@xxxxxxxxx>]

Short of generating a CD serial number list for clients and they doing
immediate cataloging to track their quality control process, I'm not sure
how a studio would go about this.  Labeling printed on a robust surface is a
far more practical solution for those of us engaged in being an out source.

Some seroius testing of the various labeling systems needs to be done, and
quickly.
