Swell-Form Graphics Machine
The Swell-Form Graphics Machine (often referred to as a fuser) is a simple, fast and low cost method of creating stunning tactile maps, diagrams, text and graphics. This machine has revolutionized the process of creating these tactile images. Using the special Swell-Touch paper, simply print onto this paper as you normally would through your standard printer or copy machine (we recommend a laser printer/copier, as it creates finer lines). Once the desired image is onto the Swell-Touch paper (or, swell paper, capsule paper, microcapsule paper, flexi paper), run this paper through the Swell-Form Graphics Machine. As it goes through this machine, the heat reacts with the black ink (only the black ink, no colors) and causes it to “swell” or puff up, creating the tactile image. The rest of the paper and any colors, will remain flat.
