The White Gloss Laser is a solid white material but does not have an opaque backing for covering up text and images. Depending on what is printed, it might work well for you but I would recommend visiting the link below to request samples of this product along with the OL177BT. The BT is our Blockout for Laser material which has a matte finish but but offers a gray opaque backing intended for covering up existing labels. https://www.onlinelabels.com/samples
