I am looking for CD/DVD labels that will block out existing printing on the disk. I have been using "Stick It Right" labels by Great Gizmos and they do an outstanding job since they have a foil backing. Unfortunately, these labels were apparently discontinued about 3 years ago and my supply is about to run out. I can't seem to find anything other than plain white labels. The printing on the disk still shows through. Can anyone recommend a replacement? Thanks, Gary
