okay, here's the lowdown on CD-Labeling:
There are 3 major labeling names: Avery, Neato, and Multi-Flip (made by CoolaBella).
Neato labels are good, but expensive, and their label applicator is the worst i've EVER had the privalige of using!! Their labels can be regualr, glossy, transparent, or metallic (gold or silver). They also produce the core labels which label just the inner CD hub, which is often left bare by most cd labels.
Avery produces CD-Stomper, which is a really good system! CD Stomper is generally cheaper then neato, their labels are good, and their applicator is good (my personal favourite). Like neato they have all sorts of labels, but I don't believe they produce labels for the hub of the CD, or metallic labels. They DO however make Jewel Case inserts, which you would probably be interested in for your demo CDs.
Multi-Flip makes the most expensive labelling Kit, but in some ways it's the most superior. The label applicator is the only one of the three that comes with guides for labeling the business card CD-Rs, which because of their shape, can be very difficult to label. I've just had the pleasure of using the multi-flip applicator to label 100 business card CDs, and I would say it's difficult to learn, but not so bad when you get used to it. Multi-Flip labels are incredible however, they are the cheapest labels you can find, and their print quality is very high (1440 DPI). The only real downside to the multi-flip systemis the software it comes with, it SUCKS! don't use it! the labels don't even match up using their own software!! however, it's easy to download proper templates for use in other programs like phtoshop and microsoft word, and THOSE work VERY well.
In conclusion, I would recommend the CD-Stomper system made by avery. The applicator is easy to use and good quality, the labels are cheap and fairly good quality and the software works well. If you want to switch to multi-flip labels, you can always just download a template to use in other software, and that way you don't have to buy a whole seperate kit.
also, some people say that it's bad to label CD-Rs because the labels will peel. This is generally untrue. I wouldn't suggest putting an additional label on a CD-R that is already branded. But if you are working with un-branded CD-Rs (ie. silver on silver, or silver on blue, or gold on gold, ect...) then it's fine. Actually, it's probably BETTER to label un-branded CD-Rs then it is to leave them surfaceless. I hope that answers your question :)
