Thermal Transfer

In May, Appleton introduced a new line of thermal-transfer label security papers that incorporate its TechMark® Taggants and Read/Write Threads. The taggants are invisible under normal lighting conditions, but can provide quick visual verification under UV lighting. They can also be formulated in the paper to create a unique identifying code that is difficult to duplicate or alter and can be read by a handheld reader. The TechMark Read/Write Threads carry a secure, encrypted code that also can be read by a handheld reader. The data is added to the thread by a proprietary process and cannot be erased, altered, or duplicated. Both grades of the security papers have been qualified by Zebra Technologies (Vernon Hills, Ill.) for use on its line of Zebra® brand thermal transfer printers.
