Replication is a process used for transferring data from a source master onto a CD or DVD. This process is often compared with the duplication process. Although, both duplication and replication processes offer same result, they are completely different from each other. Replication means a copy that is not original, but something that has been copied.DVD replication refers to the process of ‘pressing’ copies of a DVD glass master onto polymer/aluminium blank discs. DVD replication companies are the only one who can do the replication job for you. Usually, professional replication companies offer offset or silkscreen printing onto the surface of DVD and the packaging and printing as well.The DVD replication process offers you with duplicates of your master DVD that can be played on almost all computers and DVD players. Once the source master is given to the replication company, they initially check it for unreadable and bad sectors. Without this verification step, you may end up with a number of faulty discs.On the other hand, DVD duplication is a process that uses a device called burner or a writer that copies the data from one DVD onto many other DVDs. The process of DVD duplication is ideal for small quantities of up to 500. However, if you want to create more than 500 quantities of DVDs, it is recommended to go for DVD replication process.
