PROBLEM TO BE SOLVED: To screen-process a lenticular image by the minimum Moire effect. SOLUTION: A method is provided for screen-processing of a color separation version of the lenticular image, by a lenticular frequency of a lenticular lens 10 required for observing the lenticular image. An amplitude modulated screen image is calculated as to each color separation version, using a screen frequency at a certain screen angle, and an tangent of the screen angle is a rational number. The screen angle related to a direction perpendicular to an image stripe of the lenticular image is determined as to a specified color separation version, a set of integers n, m with a quotient m/n equal to the tangent of the screen angle is determined, and the screen frequency of the color separation version is calculated as a product of the lenticular frequency and a square root of the sum of respective squares of the two integers n, m.
