The Weatherproof Thermal Transfer (TW) has a glossy finish but we also offer the Standard White Thermal Transfer (TT) which has a matte appearance. The TT material, however, is paper based and does not offer the same water resistance and durability of the Weatherproof Thermal Transfer. We have not tested our materials against AMAT specifications, however you're welcome to visit the link below to request free samples. https://www.onlinelabels.com/samples
