Abstract

A compact disc where the printed logo (13) is protected from the environment by one of the plastic layers of the CD. The disc is made by printing the mirror image of the desired logo (13) on the mating clear disc prior to bonding. The logo (13) is then viewed through the clear surface (15) of the disc, upon which surface it is not then necessary to perform any further printing.
