Abstract:
A method of creating a color print that faithfully simulates a continuous tone multicolor image, said method comprising:providing digital data describing a multicolor image; forming at least three latent images based at least on information contained in said digital data; wherein each of said latent images is formed of latent marks arranged along mutually parallel lines that are substantially uniformly spaced from each other, at a spacing of at least 100 lines per inch that is substantially the same for all the latent images; developing the latent marks to form developed marks; and printing the developed marks to form respective printed marks; wherein the printed marks resulting from any one of said latent images: a. are printed in a respective single color different from the color in which the printed marks resulting from any of the other latent images are printed; b. are at printed mark positions that substantially conform to a uniform grid of positions; c. differ at least in size, in discrete steps, along at least some of said lines; and d. are connected to each other along said lines at densities from no more than 25 percent through no less than 75 percent; wherein the printed marks resulting from said latent images form said color print that faithfully simulates a continuous tone multicolor image; and wherein the lines along which the printed marks resulting from the respective latent images extend are angled to each other in the color print to reduce Moire.
