Thai university creates cheap, touchable ink for the blind - CNET

Researchers at Thammasat University in Thailand have created something that will potentially make it a lot cheaper for the blind to read.

Called Touchable Ink, this new ink has the ability to rise when heated, tuing what would normally be a flat row of printed Braille letters to an embossed version readable by fingers, according to a media release.

Developed in conjunction with Samsung, who supplied the printers, and advertising agency J Walter Thompson (JWT), the ink will eventually be able to be used in normal printers.

Touchable Ink promises to lower the cost of printing Braille text for blind users from the current cost of $1.1 (£0.75, AU$1.50) per embossed A4-sized page to just a mere 3 cents per page using a standard printer. Furthermore, there won't be a need to pay around $2,850 for a Braille embosser.
