Detailed Explanation

ADA requires that Braille dots be domed or rounded rather than flat-topped. This specification ensures that Braille readers can accurately interpret the dot patterns by touch. Flat-topped or pyramidal dots are not compliant. The dome shape, combined with proper dot height (0.025 to 0.037 inches), diameter (0.059 to 0.063 inches base), and spacing, ensures readable Braille that meets accessibility standards.

Examples

• •Quality photopolymer production creates properly domed dots
• •Braille dots should feel rounded when touched, not flat or pointed
• •Each dot has consistent dome shape for uniform readability
