The difference between replication and duplication

Replication and duplication are terms referring to how your discs are manufactured. The words duplication and replication may seem interchangeable, but they are not. Here is the difference:

  • Replication is the process of creating a glass master and stamper of your data (CD Audio, CD-Rom, DVD video) then injection moulding the discs using that stamper.

  • Duplication is the process of taking blank, recordable discs (CDRs or DVDRs) and writing the information on them with a laser.

Disc production and print
A nickel stamper is created from the glass master, then placed in an injection molding line. The OGP (optical grade polycarbonate) is molded to the stamper, creating a clear substrate that contains your data. The substrate is then metallised, lacquered, then either CMYK offset printed or screen-printed.
