Hunko D. Development of normalized raster transformation

The dissertation work is devoted to the decision of an actual scientific and applied problem of development of adjustment and compensation of various technological influences on process of development on the basis of model of the normalized raster transformation that will increase its efficiency and quality of prints. for general analysis and synthesis of raster transformation, a model of normalized raster transformation in the form of a two-function function from the domain - a single raster square and a set of values of relative areas - a closed unit interval, which ensures the efficiency of analysis and synthesis of tone. Normalized raster transformation functions for elements of square, round and rhombic shapes have been developed, created by structural diagrams of models in the Matlab: Simulink package, which are means of modeling, calculation and visualization for various technological perturbations and influences. Similar to the previous one, a simulator was developed to calculate and construct a family of denormed characteristics for raster elements of rhombic shape of different lines. The results of the characteristic of denormed rasterization for rhombic elements of different lineage, which are symmetrical S-shaped curves, are presented. Also mathematically substantiated nonlinear adjustment of the normalized raster transformation by means of a power function, realizing adjustments for elements of different shape and defined parameters of correcting links, applying compensatory decompression by means of compensating links for different amplitude of expansion. The problem of analytical adjustment of the normalized raster transformation with the previously set (desired) gradation characteristic and determination of the parameters of the correction link in the general plan is considered.
