Raster  Method of Braille

Working with Other Materials

Plastic and metal are not the only choices for sign substrates using the 
Raster

Also bear in mind that any time you use clear Rasters

Wood:

 Most woods can use the friction-fit Raster

™ method. We have experimented extensively with different materials. 

Use the information here as a starting point, but always test an unknown 
material before using it for a job.

™, the material 

underneath will be visible through the Braille dots. If  the material under the 
surface is a different color, you may want to consider using one of  the 
opaque colors of  Rasters™.

™ method, but avoid 

softer woods. Any wood softer than pine isn't likely to be dense or strong 
enough to support the Rasters™. Plywood and manufactured wood products 
like MDF will work well.

High-pressure laminates:

 Laminated materials such as Formica® generally 

shoud use the adhesive-assist method.  In some cases, a hybrid of  the two 
methods will work best; drill the holes using the collet assembly, but insert 
the Rasters™ dry (no adhesive). 

Phenolic or fiber-reinforced plastic:

 Use the adhesive-assist method with 

these materials. Be aware that these materials are abrasive and will wear out 
tools faster than other plastics.

Expanded PVC plastic:

 Lightweight sign materials like Sintra® are not 

strong or dense enough to support Rasters™ and are not recommended.

Solid-surface materials:

 Materials such as Corian® are essentially dense 

hard plastic and will work best with the collet assembly. Like laminated 
materials, adhesive sometimes isn't necessary with these materials.

Hard stone (marble/granite):

 It is difficult to work with these materials 

without the proper tools. You can use the carbide drill bit, but it will wear out 
quickly.  If  you have access to proper stoneworking tools, and can drill 1/16" 
holes to a precise depth, you can insert Rasters™ using adhesive-assist. 

Soft stone (sandstone, etc):

 Softer stone is easier to drill into, but use 

caution when inserting the Rasters™. Use adhesive-assist, and test the 
adhesive to make sure it sticks to the stone. 

Glass:

 It is possible to drill holes for Rasters™ into glass, but it is not 

practical. The process is very difficult and time-consuming. Working with 
glass requires special tools, training, and equipment. We don't recommend 
you try drilling into glass unless you have experience.  Substitute clear acrylic 
or polycarbonate for real glass.
