Multi-dimensional lithographs which impart the illusions of depth and/or motion to a viewer are prepared by constructing and sequencing a plurality of electronic pages, preferably four or more; rasterizing, compressing and converting each page; interlacing the pages in a desired sequence; outputting the interlaced frames to an imaging device; and producing a lithographic separation from the imaging device. In the rasterization of each frame, nonbinary pixels are created that correspond to the resolution of the line count of the lenticular lens that will ultimately be applied to a print of the lithograph times the number of frames in the lithographic separation. The frames are compressed to an amount equal to the reciprocal of the number of frames from which the lithographic separation is prepared. In the converting step, the nonbinary pixels of the compressed frames are converted to individual color plates of binary pixels. The multidimensional lithographic separations are free of moire and screen interference.
