Impress your friends and family.
Let's face it--we're a style-conscious society. Grandma doesn't want that DVD of Junior hamming it up for the camcorder unless the label looks pretty. And your friends won't have any idea what's on that CD if you scribble the label on with a pen. Do everybody a favor and print a custom label directly on the disc.
Advance your career.
Printing professional-quality labels directly on your business CDs and DVDs is a smart thing to do. Prospective clients will think you have a formidable budget, and the big boss will be equally impressed by your resourcefulness.
It's better than using press-on labels.
Sure, you don't need a CD/DVD compatible printer to use an old-fashioned, press-on disc-labeling kit, but that's so retro. Now that you can create discs with a fully produced appearance, there's no excuse not to do it.
