Duplication and replication are two different methods of reproducing CDs or DVDs.

CTP Digital Services offers Replication (pressing) of CD and DVD’s.

Glass mastering: A glass master is made from a duplicated CD/DVD master disc, which is supplied by the customer. A metal stamper is then produced from the glass master. CTP Digital Services is the only replicator in South Africa with the ability to makes its own glass master and stamper for its replication customers.

Replication (pressing): The blank disc is created by injection moulding of polycarbonate. The manufactured metal stamper where the data/audio is stored, is used to stamp the information onto the blank disc. Replication is used mainly for big quantities, however, smaller quantities are becoming more frequent.
