Lightscibe doesn't use ink. The DVD burner actually etches in a label with the laser.
yes I know // I was going off your reply 3 as I was still unclear as to if it was LS or Paper..
are you comparing ur old LS CD/DVD with newer one? if so did you Etch the old one with the same setting as the new one
EX you can make LS etch them more then one time so, if you only did the old ones with one pass and the newer ones with 2 to 5 passes may be where it lies
the more passes the Darker it will be ...
