ABSTRACT:
A method and system for making a baby-plate for use in printing abstract patterns on architectural materials wherein glitches are easily confirmed and removed. A unit material is read by an input scanner (1) and the image digitized into pixels of given density. The image data of the unit material is dissolve-composited repetitively M times vertically (M being a positive integer) and N times horizontally (N being a positive integer) in an endless processor (9) to construct pattern data of given size. Some pixels are culled from the pattern data by a glitch-checking processor (10) for creating reduced pattern data for display on the screen of a monitor (14) for determining the presence of an undesired pattern, i.e., a glitch, by viewing the screen of monitor (14). If there is a glitch, then the glitch is removed by a glitch removal processor (11). The glitch removal processor (11) operates according to three schemes--scramble, pixel copy and Fourier transform--depending on the state of the glitch for providing effective and efficient glitch removal.
