CD Replication, Audio Cd Replication, CD-Rom Replication are all produced from CD Replication machines and are different from the CD Dupication. People around were confuse over the differences between both of them.

CD Replication is where one have a master copy to replicate it into bulks. The proces of CD Replication involves glass mastering, injection moulding, sputtering and printing.

Glass Mastering in CD Replication process means that a master copy is given to the replicator and the master copy will be put into a machine where they want to make a stamper (mould) out for the exact content of the master CD.

When the stamper is done, it will then be fixed into an injection machine mould and PC (plastic resin) will be moulded according to the stamper grooves. The transparent plastice which has a shape of the CD now have all the groves that is moulded out from the stamper which was made in the glass mastering process.

The transparent CD will then go through a sputtering process where aluminium target are used. This creates a reflective layer where CD player can beam its laser and have a reflective layer reflecting it.

After the sputtering process, it will go through a lacquer process where it is a liquide form to protect the layer. After this process the replica will be going through scanners where every piece is QC'ed.

After the above process the replica is then printed using silkscreen of offset plates where output films are involved. This is roughly what CD Replicaiton means.

On the other hand Cd duplication simply means that you buy a CD-R and burn it using a burner or CD burner stacked.

CD Replication and CD duplications biggest different is that every piece out from the CD Replication process is QC'ed and CD duplication is all depend on the CD-R brought and laser head of the CD burner. It is impossible to test CD's from CD Replication process as normal cd Duplicators will not have scanner on them. the second disadvantage of CD-r is that you do not knwo what grade of Cd-r that you are buying. Expensive does not mean good and cheap does not mean grade C.
