The other day, I had the opportunity to visit local CD/DVD replicator and duplicator, Next Generation Media. We walked through the plant and saw the whole process in which your CDs/DVDs are copied and mass-produced. It was very interesting seeing the discs being created and to see all of the machines going at once. They do both replication and duplication, and since many people do not know that there is a difference between replication and duplication, so I will try to briefly explain it.

When you duplicate a disc, you “burn” the data from your master disc or hard drive onto pre-manufactured recordable CDR or DVD-R discs. If you only need a small number of discs copied or just a few at a time, this will be your quickest and least expensive option. You can still make the disc look just as good as a replicated disc with high-quality printing, design, and packaging.

Replication is much different than duplication. When you replicate a disc, there is a manufacturing process involved. Each CD or DVD is injection-molded from polycarbonate pellets and shaped into a disc. They are then physically stamped with the data. They go through the whole process of premastering, mastering, electroplating, injection molding, metallization, spin coating, printing, and advanced quality control. These discs are more durable and are of higher quality than duplicated discs, but they are very expensive if you only want a small number of discs. This is because it takes time to set-up the machines, so there is a high initial fixed cost. But if you are doing a larger project (more than 500 copies), replication may be the best option for you.

I personally enjoyed watching the machine that did the four color printing on the discs. It was a quick way to vamp up the look of the disc for brand recognition, as well as give it a professional style. Now that you can decide on duplication or replication for your next project, don’t forget about all of your CD/DVD packaging options!
