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

Mechanical

Photographic/Chemical

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
