But it is even more commonplace to create a .pdf file rather than using the .brl file format. The PDF is more practical because it is an everyday format that is more widely used. The lettering is inserted in its own layer and a suitable graphics program can ensure that the lettering in the print file fully complies with the DIN standard.
The DIN standard determines, for example, the point size, height and spacing, as well as its position on the packaging. According to the standard, the braille may not cover the bar code and must be saved in the document with its own color. The finished embossing should ideally stand out 0.2 mm.
If it is flatter than this, the braille is harder to read. If it is higher than this, the overprint is harder to read. If the machine embosses too heavily, the surface of the packaging material may be damaged. The norm ensures the ideal accessibility for both groups of patients.
The final result is an optical braille template:
- A .brl or .pdf file
- With the name of the medicinal product and all available strengths in braille
- Transcribed into all target languages and proofread
- Aligned with the DIN standard
- Can be read directly by the printer or braille embossing machine
mt-g is specialized in the EU. The irresistible simplicity and efficiency of the character system has taken braille far beyond the borders of Europe. With its 64 characters, braille can be used even for languages not written in the Latin alphabet with an incredible number of characters of their own. The last fold-out box explains how this is done.
