The Wasp DT/TT label stocks are premium white matte finish coated paper suitable for virtually any retail or industrial application. All the label rolls are perforated between the labels making tear-off easier and your job more productive. Direct Thermal Printing burns an image directly onto the label and works similarly to a traditional fax machine with heat sensitive paper. With direct thermal printing, the image deteriorates over time, especially in sunlight or high-temperature environments (e.g. unairconditioned warehouses), but does not require a ribbon.
