CD duplication and CD replication are not the same

You have just recorded a music album or created a media presentation and want more copies of it but are not sure if you should have the CD replicated or duplicated? If you are confused in choosing the right process, the following information should be helpful.

CD duplication is a process that is much simpler and is not a manufacturing process. As the names suggests, the process creates copies of the CD that needs to be duplicated.

Perhaps, you may have already duplicated CDs on your computer in the past using a CD burner. The CD-R used in CD duplication has a reflective smooth layer that is laid on a layer of photosensitive dye. This photosensitive dye varies between the various CD manufacturers and that is the reason you see CDs with green, blue or silver recording surfaces in the market.

CD replication is more of a manufacturing process that includes many stages and is conducted in a controlled and clean factory environment. Here, the data from the source is transferred to a high-speed server for checking if any errors are there. The next step involves the creation of a glass master, which is stripped, washed, cleaned, dried and then primer coated and baked before exposing it to the laser. Stampers are then created from the glass master and quality checked before using an injection mould to form a polycarbonate transparent base.

Ideally, for copies of less than 500 CDs, CD duplication is the perfect choice while CD replication is suitable for more than 500 copies.
