Braille Inspection Mode lets you inspect and translate Braile regions on separate master or sample files. The Application supports digital documents and scanned copies of files containing Braille of either plateau, dome, or bell dot types.

We follow Marburg Medium Braille Specification, with Dimensions:

  • 2.5mm horizontal dot to dot

  • 2.5mm vertical dot to dot

  • 6.0mm from cell to cell

  • 12.0mm from cell to cell with a single space in between

  • 10.0mm line spacing

  • Tolerances: ± 0.1mm; Dot diameter: 1.3-1.6mm

Both frontside and backside scans are in turn supported, with Braille height information displayed following inspections of the former.

Note: High-gloss samples may require an additional finish for the Application to properly support scans of them.

There are four default actions (inspection types) available:

● Translate Master inspects a loaded master file, providing a translation of its Braille and a list of measured parameters.

● Inspect Braille Sample inspects a scanned sample file (frontside), providing a translation of its Braille and a list of measured parameters. Braille height information does display when a scanned sample is inspected.

● Compare PDF to Scan (Backside) compares Braille regions detected on the scanned Sample (backside) against detected Braille regions on the loaded Master.

● Compare PDF to Scan (Frontside) compares Braille regions detected on the scanned Sample (frontside) against detected Braille regions on the loaded Master. Braille height information does display in this scenario.

The system marks individual Braille dots as missing or extra (Compare) while letting the user modify the translation by adding/ removing dots (Translate/ Inspect).

  • Master file must be original artwork in PDF, BMP, or TIFF format

  • Braille dots must be on top-most layer

  • Braille dots must be solid-filled

  • Braille dots must be a unique color
