Electrographic technology of digital printing is used for reproduction of computer documents containing various information. This technology relates to the category of short-run-off printing (Printing-on-Demand) of Computer-to-Print type1 and possesses capability to personalize and update constantly output data obtained on the paper as hard copies of the monocolor or multicolor image. The image can be both double gradation alphanumeric (Text Information) and half-toning (Image Information).Quality of such a diverse image is usually evaluated according to several parameters, which could be theoreticcally referred to several groups:parameters of power conversion of an intelligence signal, spatial and frequency parameters, color parameters.System of printing quality parameters is also determined by requirements of ISO-13660. They are subdivided into 8 parameters of evaluation of characters and separate lines and 6 parameters of evaluation of large filled areas.However, practically all the mentioned elements are derivatives of parameters of the basic structural elements of the electrographic image. Quality of reproduction of the latter depends upon technology of digital printing and affects considerably all other parameters having visual nature mainly. The present report is devoted to analysis and evaluation of the basic structural elements.
