Multi-layer printing technology is the best tool for ADA sign (Braille sign) applications.
The thickness of a layer printing in white is around 0.5mm and can reach a maximum of 0.8mm

regulation in different countries. Apply proper ink percentage to perform multilayer printing to
reach the wanted thickness and produce ADA compliant signage.
1. ADA Sign (Braille Sign)
ADA sign (Braille sign) is a system printed as raised dot that can be read with the fingers by visually
impaired people. Braille is not a language, but a code by which many languages—such as English,
Spanish, Arabic, Chinese, and dozens of others—may be written and read. Braille is used by
thousands of people all over the world in their native languages, and provides a means of literacy
for all.
