Braille quality is defined by the consistency of dot shape, height, and alignment. These elements must remain uniform to produce readable braille.
Dot shape must be properly formed, height must remain consistent, and alignment must be maintained across the page. Variation in any of these reduces readability and affects how braille is interpreted.
In production environments, braille embossers and braille printers must maintain these conditions throughout continuous operation to produce stable, repeatable output.
Quality is determined by whether these elements remain consistent across the full production run.
