self voiding

On removing a security label, the pattern or text that remains is commonly referred to as a void message.

These materials are available in a wide range of patterns and messages "off the shelf" which offer a medium level of security as they are widely available across the industry.

For a higher level of security, you need to consider subsurface printing, surface printing, holograms or other similar features. Self voiding materials re available in clear, silver, white or a range of colours.
