DVD duplicators and CD replicators have made life easy for so many. There is no need to manufacture every CD or DVD from scratch to be used by individual users. Instead, services like CD replication produces innumerable copies of one master CD that can then be employed in myriad uses. The biggest advantage of these processes is that they reduce the cost of production by significant proportions and the time duration is also drastically reduced. Consequently, clients can produce many CDs at one go and use them later as and when the need arises.
What is CD replication?
To understand the process of CD replication, try imagining a giant printing press. In it, every subsequent copy is produced by pressing a huge block of printing set onto the printable surface. As a result, every copy produced is almost identical to the master copy which was used to set the printing block.
To achieve CD replication, a master glass copy is produced using the original CD that needs to be replicated. The digital data on this master copy is then injected onto printable CDs using sophisticated injection moulding instrument. This creates pits which can be read using specialized hardware and software to extract the requisite data. This data is also processed for additional fine-tuning and then covered with layers of treated plastic to safeguard from dust and grime.
This process is different from the way in which DVD duplicators operate. Merely copies of data are not made but an exact image of the master CD is produced through CD replication.
