The LightSafe(TM) Technology consists of a unique chemistry that maintains a pristine label appearance and high scanning reliability for linear and stacked bar code symbologies for two or more years. These properties make LightSafe(TM) 300 direct thermal paper the ideal label medium for handling the demanding requirements of long-term storage.

Our test results prove with certainty that LightSafe 300 stays white longer than any direct thermal label paper on the market," Cove said. "This breakthrough ensures the long-term durability of direct thermal media. Now, end users in warehouse and supply chain applications can convert to direct thermal for their long-term label needs and take full advantage of its technological benefits and corresponding better overall value.

Thermal paper is paper that is impregnated with a chemical that changes color when exposed to heat. It is used in thermal printers and particularly in cheap, lightweight devices such as adding machines, cash registers, and credit card terminals.

The paper is impregnated with a solid-state mixture of a dye and a suitable matrix; a combination of a fluoran leuco dye and an octadecylphosphonic acid is an example. When the matrix is heated above its melting point, the dye reacts with the acid, shifts to its colored form, and the changed form is then conserved in metastable state when the matrix solidifies back quickly enough.

Controller boards are embedded with firmware to manage the thermal printer mechanisms. These controller boards? features are designed to meet the needs in terms of functionalities and specifications.
