These labels are printed on a special vinyl that has the word "VOID" throughout the adhesive system. When the label is removed it leaves the word "VOID" on the surface and through the label. The label cannot be re-applied without it being obvious that it has been tampered with. It's the ideal way to prevent unauthorised transfer of labels eg. permits and certificates, or opening of goods to void warranty.
Example of common uses are the back of computer cases and other electronic equipment. These labels are mirror silver in colour and can be printed on in most spot colours but not 4 colour process.
The background should remain silver with printing of text only, otherwise you will not see the void marking through the sticker.
