Investigation of Resistance to Mechanical Effect of Braille Formed on Different Materials

Abstract

Qualitative analysis of stresses emerged in paperboard during Braille embossing, using specialized polarimetric equipment, was carried out. Resistance to mechanical effect of Braille dot surfaces, formed with different printing types on different materials (paper, paperboard, polymer, textile, Al foil) was investigated. It was determined that Braille dot height change after period mechanical effect is different.
