CD Replication Process
CD Replication is the industry standard procedure for manufacturing audio CDs. CD Duplication uses enhanced CD-R media and 'burns' the data to a heat-sensitive surface, whereas CD Replication actually "presses" the audio onto an aluminum and plastic disc, creating physical pits in the surface. This replicated CD is then covered in a clear plastic layer, to stop the pits collecting dirt and dust.

Uses of CD Replication
The process of replicating CDs is ideal for orders of 1000 units or more. The reason for this is that while the setup cost of producing a glass master and formatting the machines for your job is high, the cost of producing each unit is very low. When you are producing 1000 CDs or more, the costs of CD Replication are generally lower than the costs of CD Duplication.
