The Difference Between CD Duplication & Replication


If you’re a musician looking to break onto the scene and get your music out there to as many people as possible, there is a lot to consider when it comes to how best to release your material to your new fans and prospective fans.

Whether it’s which songs to release, how to design your album artwork, and the length of the album, there are a lot of decisions to be made. One of the most important decisions is which formats you want to release your music on.

It goes without saying that streaming is the number one choice these days for many people, but there are many other formats to think about too. Vinyl is making a serious comeback in recent years, and there is even a growing trend for releasing material on cassette, but one format that has stood the test of time and still remains popular is the CD.

Most people still have a CD player, whether that be in their home, car, or both, and a CD can be played on home entertainment systems and laptops, which makes them one of the most accessible non-digital formats out there.

So, if you’re thinking about releasing a CD yourself, you’ll need to know a few things to help you make the choice between replication and duplication. With that in mind, we’ve put together a bit o a guide to help you out!

How are they made?

The main difference between duplication and replication is the method used to produce them, and knowing more about this process will help you to identify which is best for your specific needs more easily.

The process of CD duplication is not too different from that of burning a CD yourself at home, but of course it is done on a much bigger scale. The discs are pre-manufactured, and then your data is overlayed onto it using lasers.

On the other hand, CD replication is when the CDs are manufactured with your data built into the CD itself. A glass master disc is made, and then each CD is pressed from that as opposed to just overlaying data onto an existing CD.

When to choose duplication

Duplication tends to be the best choice for small runs of units, especially if you want to make 500 CDs or fewer. The process is much less labour intensive than replication and so it works out more cost effective for smaller batches.

It also has the benefit of having a short turnaround time, which is perfect if you need your CDs quickly for a gig. You’ll usually get your CDs in a few days!

When to choose replication

Replication is better for large quantities and superior quality, and you’ll tend to find that the cost of producing the master disc becomes more affordable the more CDs you are having made. The process also allows the data being burned to retain it’s integrity much better which results in a higher sound quality.
