Аннотация This paper is devoted to the new method of creation of the multi-color flock patterns. This method has been developed at St.-Petersburg State University of Technology and Design, and its grounded on usage of effect of the flock separation in an inhomogeneous electric field. It has a series of advantages as contrasted to by known technologies of deriving of flock patterns. The mathematical model which describes the flock separation process is developed. This model allows to forecast distribution of a density of flock on a material. The model enables to evaluate dynamic of change of the flock density. The empirical dependences that evaluate influence of the basic technological parameters of process on a pattern for an electrode, consisting from parallel wires, are introduced. The character of this influence is remained at usage of an intermediate electrode of more compound shape, that allows to forecast the obtained pattern
