Microcapsule Paper

A specialized paper used to create raised tactile graphics, containing heat-sensitive microcapsules of alcohol embedded in its surface. When black carbon-based ink is printed on the paper and then passed through a heat fuser, the microcapsules beneath the dark areas expand and raise, producing a tactile surface that can be read by touch. Microcapsule paper is widely used in accessibility contexts to produce tactile maps, diagrams, charts, and educational materials for people who are blind or have low vision.
