Modeling of the Process of Braille Formation

One of the tasks of social development is the creation of equal opportunities for all segments of the population, including people with disabilities. Therefore, a number of famous and latest technologies are used to provide the information component in the life of blind people. Braille is the traditional way of obtaining information for visually impaired people. The analysis of scientific and technical sources, and patent information showed that a number of technologies are used with the Braille system, the most promising of which is the screen printing method, which allows adjusting the layer thickness on the print. The requirements for the thickness of the ink layer can be completely different. The field of application of screen printing sometimes imposes opposite requirements on the thickness of the ink layer on the print. When it is necessary to apply relief-dot images for reading by people with vision problems, this is achieved by a large thickness of the ink layer. Therefore, it is important to mathematically describe the influence of the main parameters of the screen publishing plate and the process of printing relief-dot images to ensure the required height of the Braille elements.
