The CD duplication process starts with a master CD-R that is ready to be copied. Your CD master will duplicate the exact content onto your copies so you want to make sure you have proofed your master for any imperfections. In order to copy multiple CD copies you will need a duplication tower with several CD burners or you will want to find a company that can do the copies for you. The CD duplication process is done by a laser passing through the dye of the CD burning the information onto the disc. CD duplication is great for small quantity runs usually under 500 disc. The other advantage of CD duplication is the turnaround time is much faster than the replication process. Many times people will choose the duplication process for higher quantities of 500 if there deadline can’t be met by using the replication process.
Perfect Image Video states that if you are going to choose the CD replication process you will need to start out by having a finished ready to copy CD master. When your CD master is sent out for replication the company is first going to create a glass master that contains the image of your CD. After the glass master is created it is now ready for replication. This is done by using the glass master to stamp each CD pressing the information into the plastic mold. Once the CD has been pressed it will have a coating sprayed on the bottom to protect the disc. The replication process gives you a more durable CD and usually will last longer. CD replication is good for quantities over 500 disc and you will see the best pricing when ordering 1000 or more disc. Expect the turn around time be between 7 to 10 working days.
