I did not buy the expensive blanks immediately for the first experiment with LightScribe me. Until now I had no failure - the labels are clearly visible and sharp. I admit in a direct comparison are trademarks blanks what the sharpness or contrast concerns still have the edge, the difference for me is not important because not much. Contrasts can also be improved by the blanks are simply left still for an additional run in the burner.
Note: The blanks are not enough - and the torch must support LightScribe technology.
