INVESTIGATION OF GEOMETRICAL AND PHYSICAL – MECHANICAL PARAMETERS OF BRAILLE BY ASSESSING THE DIFFERENT TYPES OF CARDBOARD MATERIALS
For people with visual impairment, one of the means of full integration into society is provision of Braille in their environment, including information on multipurpose packages. Properly formed elements are very important for the readability of Braille font, which after some handling should remain easy readable by the blinds.In this paper, investigations of different types cardboard which is mainly used as a packing material in pharmaceutical industry as well as resistance of Braille surface to mechanical factors were carried out. Dispersion of geometrical parameters of Braille formed onto paperboard packages is analyzed. Conclusions based on the performed investigations are provided.
