摘要： A method of setting frequency rate and angle differences between screens where moire patterns are not generated is provided. The method of setting the frequency rate and angle differences of the screens includes forming a binary image using at least two overlapped screens, and low-pass filtering the binary image to calculate an average reflectivity. A frequency component (cost) is calculated with respect to the binary image using the calculated average reflectivity. It is determined whether a moire pattern with respect to the binary image is generated based on the frequency component. Accordingly, the binary image where the moire pattern is not generated may be formed.
