Normalization of three-colour printing synthesis in production of maps

The main factors of the printing process, influencing the transfer of colour space, were investigated with the aim of detection and investigation of those main factors and to normalize the optimum values of those factors as well as the permissible deviations undes the conditions of production of maps. As a result the regularities of formation of spectrum-modulation properties of the colour layers were investigated and the correlation between the spectral characteristics of the multicolour layers and one-colour layers was detected. The methods for determination of the optimum combination of the relative thicknesses of the three colour layers, ensuring the achromatic field, were developed. The results obtained were introduced into spactice. It made it possible to ensure more severe control over the colour reproduction of the background elements of the maps. The programmes and methods, developed in this paper, were recommended to be used on map-producing plantsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
