Abstract
An indirect thermal transfer printer applies images to label stock with the use of heat activated transfer ribbon. Once an image is printed, a negative of the printed image remains on the exposed transfer ribbon. Heat is applied to the exposed transfer ribbon as it is spooled to obliterate the negative, fuse the ribbon to previously exposed and spooled ribbon, or both.
