What equipment is required to edit, print, and use these tactile images?
Editing the images
- an online Braille translator, such as https://www.brailletranslator.org or https://www.branah.com/braille-translator. We recommend Grade 2 (contractional Braille).
- Swell Braille font is the recommended font for tactile graphics produced by the method described below.
Printing the images as tactile graphics
The images in this resource collection must be printed out on thermal capsule (or “swell”) paper (8.5 x 11 sized paper is the best size for the images in this database). Your institution’s disability office may have capsule paper available to use, but if they do not, here are a few vendors:
The graphic must first be printed directly on the swell paper before it is passed through the PIAF machine. Dark areas containing carbon are activated by heat within the PIAF machine and expand producing a raised area on the paper. In our experience, images printed with toner-based laser printers produce a much better result with the PIAF than those produced with inkjet printers.
Next, the thermal capsule paper with the image on it must be passed through a machine that heats the paper to produce the raised relief. Again, your institution’s disability office may already have one, but if they do not, here are some vendors:
