While our RL926DT can be used with most direct thermal Zebra models that take a 1" core, the Standard White Direct Thermal (DT) material does not feature an opaque backing to block any text or images it's placed over. Alternatively, we offer the Blockout for Laser (BT) material in 8.5" x 11" and 8.5" x 14" sheets here: https://www.onlinelabels.com/materials/blockout-laser-labels. You're welcome to try samples of either option at the link below. https://www.onlinelabels.com/samples
