I have printed and fired recently 40 blanks at a time - no one was faulty and the Lightscribe result to be proud of, although it's a little pale at "normal" photos. It should be recommended, to enhance the contrast of the image geschwünschten with your photo application in advance, then the result is even better. But that is a problem of technology per se and does not address the legitimate 5 stars for the quality of the blanks.
