The development of tactile sensitivity in children may compensate for the visual defect to some extent. In the process of the object perception based on touch and tactile sensitivity, children form their ideas about the shape, volume, size, texture and some properties of objects. They develop the skills of reading dotted Braille and relief images (drawings, pictures, diagrams). Different types of printing technologies are used to apply Braille in the production of educational and methodical, didactic materials, packaging and various types of non-publishing products. One of the most promising technologies for applying relief-dot images is the screen printing method, which allows one to apply thick ink layers. This increases the reliability and accuracy of reading Braille elements. The advantages of the screen technology are also the ability to print on a wide range of materials of different configurations and the ability to provide significant resistance of relief elements to mechanical impact during transportation and reading by the blind. The main element of the screen technology is the printing plate, which affects the amount of ink that can be transferred to the material to be printed. The maximum amount of ink that can be retained on a screen printing plate is called the ink capacity. The ink capacity is affected by the parameters of the mesh and the thickness of the copy layer. The main parameters of the printing plate and the printing process influence the height of the relief-dot images on the imprint. Based on the regression and correlation analysis, the influence of the main parameters of the printing plate (ink capacity, lineature, mesh wire diameter and plate thickness) is determined, which provides the required height of a Braille element on the imprint in the range of 100 μm or more.","PeriodicalId":166274,"journal":{"name":"Scientific Papers (Ukrainian Academy of Printing)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124560599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To solve this problem, methods of transformation of signals and images, their reproduction by printing means, mathematical modelling theory for demodulation of raster transformation – object-oriented programming in Matlab: Simulink application package have been used for designing a structural scheme of a model for demodulation of raster transformation and constructing a graduation characteristic of a linear raster scale for different lineatures. In the study, an imitation demodulation model has been developed to determine the optical density of a linear raster scale of various lineatures, provided that the die optical density is constant. The simulation of the demodulation process is carried out by the corresponding change in the area of the raster elements provided that the ink thickness on the surface of the raster printing elements throughout the interval of tone transfer is constant. The structural scheme of the linear raster scale demodulation model in the Matlab: Simulink application has been constructed and processed, which makes it possible to calculate and design the characteristics of demodulation of the linear raster scale for different lineatures. The results of the imitation modelling have been presented in the form of graduation characteristics of demodulation, which are not linear curves whose curvature depends on the lineature. The scientific novelty of the obtained results is that for the first time a simulation model of demodulation of a raster transformation has been constructed, which enables to design gradation characteristics of the raster scale demodulation, and their properties have been analyzed. The simulator of the raster transformation demodulation has been constructed, which allows to calculate and design gradation characteristics of demodulation at the stage of rasterization preparation in order to improve the accuracy of the model of the raster transformation demodulation.","PeriodicalId":166274,"journal":{"name":"Scientific Papers (Ukrainian Academy of Printing)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115375345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
