What is a DVD replication check disc?

A replication DVD check disc is "pressed" with the actual DVD replication press, and it is created with the same glass master that will be use to press the rest of the project.

It is the only safe way to proof a replicated CD/DVD, because all the CD-R or DVD-R that we can create from computer & recorder are "burned", especially if you are concern with the layer break of a DVD-9 project.

It will however delay the overall production time for a few days.
