The Raster® Method is a patented process. To use this method of Braille on signs, you must be licensed. The Raster® Pen Kit includes a license to use the patented techniques and devices. No Raster® Braille products can be sold to an unlicensed user.
To become licensed, Accent Signage Systems needs to receive a completed & signed Raster® License Agreement. Once we receive the signed agreement along with payment, we can release a Raster® Pen Kit and license certificate.
The Raster® Braille License Certificate never expires.
