Congratulations on your purchase of the
Raster™ Method of Braille. Raster™ Braille
is the fastest, easiest way to create fully
compliant Braille signage.
To use the Raster™ Method you need a rotary
engraving machine and software capable of a
single-point drill function. You should also
use Braille translation software to ensure that
your Braille is accurate Grade 2.
When properly produced, Raster™ Braille is
durable, impervious to environmental
conditions, easy for Braille readers to use, and
fully compliant with all regulations.
We strongly recommend that you read all
the instructions in this booklet before you
begin.

Raster Method of Braille
What's Included
The Raster™ Method consists of three main
components: the cutter, used to drill holes in
the sign; the Rasters™ themselves, precision-
machined spheres of acrylic, stainless steel, or
brass, and the Raster™ Pen, a simple-to-use
mechanical device for inserting the Rasters™
into the sign.
How It Works
It's simple: Translate text to Braille, drill the
corresponding holes, and insert Rasters™.
The top portion of each spherical Raster™
stands above the surrounding surface, creating
a perfect dome-shaped Braille dot.
The substrate material you choose will
determine the installation method you use.
For most engraving plastic, wood, and other
soft materials, use the friction-fit method. For
metals, stone, and harder plastics like
phenolic, use the adhesive-assist method.

Grade 2
Braille
If you just type in
text using a Braille
font, you are
creating Grade 1
Braille, a direct
letter-for-letter
translation. Grade
2 Braille, on the
other hand, is
condensed, with
over 200
contractions where
a single character
can stand for a
group of letters or
even a whole
word. Grade 2
Braille is required
by the ADA
Accessibility
Guidelines.
