I am not sure what forum to ask this on . I am now using a Lightscribe drive to produce a video CD. I then do some hand inscription and optional autographing. I inscribed the first several hundred using a Sharpie marker and all went well. Then I bought another batch of discs and produced them with a higher contrast level. I have noticed that either the surface has a glossier level or that the higher contrast level has made the surface a bit slick. The sharpie does not right as well on the new batch. I even bought a new marker and am sure it is the disks. I had to go buy the Office Depot brand instead to finish the hand inscriptions. What do you think the problem is with the disks. I do know that Lightscribe disks are in general less conducive to hand inscription than regular disks. However, I am unsure why one batch differs from another.
You have to keep in mind that all the discs are produced in mass bulk in other countries. The companies producing the discs will go with whatever compounds are cheapest, but still will work adequately.
Discs will vary between brands also. Some companies coat the top with a layer of clearcoat, others don't. That may be your difference. There is no gloss standard for CDs, so you may have to expect every spool to be different unless you buy all at the same time.
At work, we use TDK discs and they seem to be very consistent. Just find a brand that is good, and order in bulk, preferably from the manufacturer, so you don't have to worry about the surface changing...
Odd. Have you contacted the retailer? They may send you a new batch.
I have changed marker brands. Although the Sharpie does not print well on all disks, the Office Depot store brand (I believe called Foray) does. I have not contacted the vendor because of the extent to which I have already printed the disks.
