ABSTRACT:
A screening system and method are disclosed for reproduction of images in printing. The screening angles that are used are close, but not identical to conventional screening angles. The reproduction is nevertheless Moire free by the fact that the deviations in angles from the conventional system are exactly offset by the deviations in line rulings. The screening system is particularly advantageous when used for combinations of screens with rational tangent angles. The Moire free combination of rational tangent screens can be rotated by a constant angle with the amount of rotation controlled in small increments.
