Multidimensional lithographs which impart the illusions of depth and/or moti on to a viewer are prepared by constructing and sequenci ng a plurality of electronic pages, preferably four or more; rasterizing compre ssing and converting each page; interlacing the pages in a desired sequence; outputting the interlaced frames to an imaging device; and produci ng 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 frame s in the lithographic separation. The frames are compres sed to an amount equal to the reciprocal of the number of frames from which the lithographic separation is prepared. In the converting s tep, the nonbinary pixels of the compressed frames are converted to individual co lor plates of binary pixels. The multidimensional lithog raphic separations are free of moire and screen interference.
