Abstract
A roll of direct-thermal material may have a length of direct-thermal material including a facestock. An adhesive layer is on a first side of the facestock. A direct thermal coating is on a second side of the facestock, the direct thermal coating configured to selectively darken by heat activation when direct thermal printed. a cured ultraviolet LED coating is on the direct thermal coating, the cured ultraviolet LED coating having photoinitiators with substantial activation at an exposure limited to LED radiation at a 365 nm-450 nm wavelength range, and configured to allow direct thermal printing of the direct thermal coating therethrough, the cured ultraviolet LED coating curable without heat activating the direct thermal coating. The length of direct-thermal material being rolled on itself.
