Abstract:
A method and system to generate a moiré-free to all-orders N-color screen-set by a lattice-based screen design the method including choosing a lattice in frequency space with basis vectors u1 and u2 such that (∥{right arrow over (u)}1∥,∥{right arrow over (u)}2∥,∥{right arrow over (u)}1±{right arrow over (u)}2∥)>f min, where f min is the minimum moiré invisible to the human eye, and choosing a set of N pairs of fundamental frequency vectors on the vertices of this lattice to be the screen vectors.
