A quote from a website on overprint CD-Rs:
"What are overprints?
[i]When manufacturers are printing CD-R’s, there’s a certain percentage that get printed wrongly. The normal procedure is for these discs to be overprinted to cover the original error and they can then be sold.
The nature of these discs means that they may sometimes have been handled by people more than non-overprinted discs, so you may find fingerprints on some discs. [/I]"
Does anyone here have any direct experience or opinions based on the reliability of such media? On one hand, fingerprints are annoying, but a soft cloth would solve the problem.
Also, being overprinted, the disc would be thicker than usual. Is this a problem?
Finally, is it OK to clean a CD with a moist cloth? I read about lifespan testing of CDs in high humidity so presumably there must be some effect on the CD in terms of humidity. But what I don’t see is that the CD does not (apparently so, anyway) contain any water soluble substances. In fact, it is mostly made out of plastic which is impervious to water anyway. Can anyone explain the supposed environmental effect of water on a CD’s lifespan?
