A white underlay refers to a thin layer of white ink that is applied underneath the main design or image of the sticker. We do not print with white ink because bamboo has a natural, organic look and feel that many people find appealing. Adding a white underlay can detract from this natural aesthetic and give the sticker a more artificial appearance. Bamboo has a unique texture and grain that can be visible through the sticker.

Adding a white underlay can increase the cost of production, which may not be necessary for bamboo stickers.
