ADA Braille: Rasterʂ Method vs. Photopolymer

Applied signage with the Rasterʂ method for Braille is easy, secure, clean, durable, cost effective, and 100% compliant with ADAAG and ANSI regulations and standards. How do photopolymer signs compare?


Applied Signs

Photopolymer Signs

Manufacturing Process



Equipment and Supplies Needed

Engraving machine, cutters, Rasterʂ Braille kit

Darkroom or imagesetter, processing machine, water supply, painting operation, screenprinting or hot-stamping operation

ADA and ANSI Compliance

Fully compliant with all laws and standards. Spherical Rasterʂ produces rounded Braille.

Difficult to comply with standards for Braille, especially cross-section thickness. Very difficult to produce rounded Braille dots.


Service and Replacement

Fast, simple setup and standard colors, easy to replace or update signs.

Paint/ink match can be a problem. Short runs nearly as costly as long runs.

Durability and Vandal Resistance

Excellent durability, outdoor grade material available. Inlaid letters and graphics offer excellent tamper-resistance.

Painted surface is not as durable as solid color material. Exterior material available, but still susceptible to moisture. Not "1-piece" construction as claimed
