Charlotte's Web Studios offers both CD Replication & CD Duplication services with Offset or Silkscreen printing, as well as printing onto blank (recordable) CDRs.
The Difference between CD Duplication & CD Replication
In Duplication, the CDs are reproduced by individually "burning" each CDR. Utilizing a laser, information is sequentially written or burned to a CDR.
Replication is a manufacturing process whereby a mold of the data, called a Glass Master, is made and then "stamped" onto blank media. It's a much faster process, but isn't cost effective on runs under 500.
Why We Recommend Offset Printing over Silkscreening
Simply put, Offset Printing looks better! Offset printing is 175 lines per inch (vs. 85-135 lines per inch for silkscreen). The more lines per inch, the better (smoother & clearer) the printing looks!
There is no "knock-out ring" cutting into your image (it's truly "edge to edge" print coverage).
Because offset printing uses plates and rollers to transfer the ink to the CD or DVD surface, the coverage is smooth and even. (there are no "screen marks" on the CD surface)
