Quality control is an important step of CD duplication, CD replication, DVD duplication and DVD replication process. When we first receive a customer’s master, it is checked for playability on a DVD player, computer and stereo. We look for errors in menu navigation, skipping, freezes in video, extreme audio levels. The disc is inspected for physical damage such as scratches and dust. Customers are notified of any potential problems before we start actual production. The duplicated or replicated discs are randomly checked under the same guidelines to ensure consistent quality.

In large run replication, specialized machines are used to verify data on the discs by comparing the 1′s and 0′s of the discs, to ensure the highest level of quality among the thousands of discs that are being produced.
