You have probably heard of copying a CD or ripping a DVD before. You may have even done a little bit of it on your own computer. When people hear about CD/DVD duplication and replication, however, they often think of them as the same process. Duplication and replication are a little different, however, and knowing the difference will help you decide which process is best for you when using a professional printing service.
Duplication means making a copy of your CD/DVD, usually using a laser. The laser burns the information onto the disc, hence the term “burning a disc.” The information is taken directly from a master disc, housed in a computer, and then burned onto subsequent discs. Only the information from the master disc is burned. This process is usually quite affordable and takes very little time to complete.
Replication goes through a slightly different process starting with the creation of a glass master. Often, data can be added to the disc during this manufacturing process. An injection molding or stamping device is usually used to create the replicated discs. Although sometimes considered more expensive due to its manufacturing nature, replication is still affordable with larger orders in most cases.
While CD/DVD duplication and replication might sound the same, the processes are quite different. Consider carefully whether you need duplication or replication with your order. If you are unsure, you can usually ask your print service which might best suit your needs.
