History of Braille

Not particularly relevant to my printing process but I did a bit more research to gain a better understanding of how it works and make sure that the text on my posters is correct. I have also been thinking about having the text printed but working with the same really small scale to make sense of the rest of the poster.

"The invention of the six-dot raised alphabet system was truly a revolutionary invention. Because of the combination of dots, it didn't take too much space. With this system it was also possible for a person to learn how to write, something that had been impossible with the raised-letters-system.
Each Braille character, or cell, is made up of six dot positions, arranged in a rectangle containing two columns of three dots each. A dot may be raised at any of the six positions to form sixty-four possible subsets, including the arrangement in which no dots are raised."
