My one and only experience with labels was that they tend to pull the substrate off the disc if you try to smooth out any air bubbles. That renders the disc useless (unless you want to hang it up to use as a bird-scarer!).

Although the disc is READ from the underside, a CD-Rom has the recording dye sprayed on the TOP, which is where you stick the label.

I've been using inkjet printables for many years, now, and have a dedicated CD printer (Primera Signature III) which was expensive, but the registration is always accurate and the print quality excellent.

I'm using Verbatim printables with the print surface all the way to the centre hole these days, and am quite satisfied with the results - as are my customers.

My only grumble is that my 1:7 duplicator copies CDs faster than I can print them! Seven copies in around two minutes! The printer takes around a minute per CD, depending on the image.
