CD replication creates an exact copy of the original master, while duplication burns data onto a disc. Replication is better for large quantities and professional packaging, while duplication is cheaper for small runs. Replication involves creating a glass master and injection molding, resulting in high-quality copies. The cost of replication is mainly in setup fees, while personal duplication only requires a computer system, CD burner, software, and blank media.
The difference between compact disc (CD) replication and CD duplication is that replication is a professional process that creates a CD by shaping the disc to be an exact copy of the original master. The data cannot be added or changed in this case. Duplication, on the other hand, refers to burning data onto a disc, as is done in home computing.
CD duplication for personal use is cheap and convenient, making it the best choice for small-run needs. CD burners and popular software both do an admirable job of duplicating audio tracks or data files onto CD-R (recordable) or CD-RW (read/write) discs.
There are cases, however, where replication is a better choice. For example, if someone has burned a CD of original music and would like to make 500 copies or more to send as promotional material to national radio stations, music labels and talent scouts – or to sell at concerts – replication will be cheaper and ensure long-lasting copies. and reliable at the highest level. The process will also include label artwork and packaging, giving the CDs a professional look.
In CD replication, an original master is used to create a glass master, which in turn allows a series of stencils to be made. High tech injection molding creates exact clones of the master, using stampers. This is followed by a layer of reflective aluminum, sealed with a protective layer of UV-cured lacquer. Each CD is made this way, essentially a first generation replica. From here, the discs pass through a label graphics printer.
Replication has many advantages, including accuracy, quality, quantity, and packaging. It’s the clear choice for a professional finished product that needs to be produced in significant numbers. The larger the order, the better the price reduction will be, and the prices will fluctuate. For small runs of just 300 or so, someone might expect to pay around $2 US dollars (USD) per CD, for example, while for runs of 1,000, the price usually drops well below $1 USD each , and for larger runs, it should drop even more.
The main expense of replication is in setup fees, leading to the common practice of requiring a minimum print run of at least a few hundred copies, although some companies will fill smaller print runs for a premium. Artwork and other considerations will also affect the price.
In personal duplication, there are no costs apart from the raw materials of a computer system, CD burner, duplication software and blank media.
