Abstract
Abstract A method for breaking-up symmetry of matrix elements in an electronic half-tone screening process screen function period, said method comprising the steps of: A. determining the x-coordinate values of a plurality of X-Y coordinate elements in at least one matrix of the screen function period; B. determining the y-coordinate values of a plurality of X-Y coordinate elements in said at least one matrix of the screen function period; C. adding a first plurality of irrational numbers to the corresponding plurality of x-coordinate values in said plurality of X-Y coordinate elements; and, D. adding a second plurality of irrational numbers to the corresponding plurality of y-coordinate values in said plurality of X-Y coordinate elements. p
