Harpo PIAF (Pictures In A Flash) is a heater – a swell form machine – for swell paper from Harpo in Poland. When a sheet of swell paper passes through the PIAF, the black lines, text and shapes rise so the drawing can be read by touch. This is how you make tactile maps, diagrams and drawings in seconds.
HMI no. 134087 in Hjælpemiddelbasen, the Danish database of assistive technology.
How it works
- Draw, print or copy the image in black on swell paper.
- Run the sheet through the PIAF.
- The black areas rise. The rest of the sheet stays flat.
Start with a low temperature, and only turn it up if necessary. The same sheet can be run through again if you want to add more details.
