Braille Dot Height Standards

Print The Highest Quality Most Readable Braille Dot

One of the most important characteristics of high quality braille to readers is the height of the braille dot itself. Inconsistent heights and low profile braille dots are difficult to read whereas higher braille dots are naturally, easier to read. A legible braille dot through it’s height is so important that a .48 mm or higher height is the minimum requirement for paper embossing in many countries around the world. For these reasons all Braillo braille printers emboss a braille dot at a .5mm height. When you consider purchasing a Braille printer to create braille documents for governments and businesses around the world only Braillo can give you the confidence you will be compliant.


A Rich Reading Experience Through Braille Dot Height

Have you ever received a document in school from a teacher where the ink toner had gone weak and faded out so badly that parts were unreadable? Often this was because your teacher was trying to print or copy 1000 pages for her students on a simple personal printer. By pushing the printer or copier past its limits the quality of the documents suffered greatly, especially the ones near the end of the printing. This very similar to what is happening with sub-standard or consumer grade braille printers that are attempting to run at production level speeds. These braille printers or embossers were built for light duty, they can be decent braille printers, but only when used for very small workloads. You can identify a consumer grade braille printer as they are normally very much like a PC printer, they are small, made of lightweight plastics and have smaller printing components. Some companies may assemble 2-4 of these consumer level machines together into one “unit” and call it a production embosser, which is akin to putting 4 bicycles together and calling it a motorcycle. When attempting to run a consumer level printer at a high speed or for a long duration they are quickly pushed past their limits and the braille dots become inconsistent, their spacing and placement get wild producing wavy patterns and the braille text becomes extremely difficult to read. To make matters worse many braille printers on the market today intentionally use a low braille dot height which may slightly increase their embossing speed but at the very high cost of poor readability.

When a Braille dot is misplaced or has a low profile it is similar to a sighted reader attempting to read inconsistent and faded text.  The experience is difficult and frustrating like the example below:


Braillo True Production Braille Printers Are Built for High Volume, High Quality Printing

All Braillo braille printers emboss braille dots at .5 mm in height making for the best reading experience for your customers.

Braillo braille printers are constructed with precision engineered, strong metal components and fixed embossing hammers. The combination means there is virtually no lateral movement while embossing which allows you to print at extremely high speeds 24/7 while still maintaining the highest quality formatting. You will not get wavy lines and misplaced dots. This is what it means to have a True Production Braille Embosser. You can see a comparison of a Braillo production braille embosser and what other companies call a production embosser here.

Perfectly Aligned Braillo Braille Vs. Competition

Braillo Braille is known as the easiest to read and the reason is simple, our Braille is perfectly aligned and the dots are where they’re supposed to be. When the Braille isn’t where it’s supposed to be, the reader has to try and guess what the word is supposed to be, or stop and re-read the sentence.

Look closely at this image to the left (click to see a larger view) and you’ll see that our competition’s Braille output is wavy and the dots within the rows and columns are not perfectly aligned, whereas the dots from a Braillo are exactly where they need to be.

Would you risk delivering poorly formatted braille with low dot heights that don’t meet a country’s set standards?  Trust in a Braillo to produce Braille documents efficiently, with production level speed, with superior formatting and a .5 mm dot height to meet or exceed Government requirements. All Braillo’s include Braille translation software and the industry’s leading 3 year warranty.
