The Disability Discrimination Act 1995 (DDA) demands that sign manufacturers conform to best practice guidelines and ensure that signage solutions, including internal signage and external signage, must be compliant and accessible to all, including the visually impaired.
Interplan has developed a number of production processes to produce coherent, cost-effective tactile and Braille signs that integrates completely with an overall signage scheme without restricting its design.
We recommend the following tactile and Braille elements are incorporated to a signage scheme to ensure compliance:
Tactile embossed characters of between 1mm to 1.5mm in thickness, set in a contrasting colour to its background, greatly improve signage legibility. All interior and exterior signs should in turn contrast with the surface on which they are mounted to remain fully compliant.
Braille comprises a number of raised dots that create recognisable characters. It should be used in conjunction with tactile text wherever possible. The ideal dot is a 1.4mm diameter sphere that is set just over half its depth into the surface of the sign.
Interplan’s range of materials, finishes, effects including illumination and corporate branding can be incorporated into all DDA compliant signage schemes.
