ABSTRACT PATTERN PLATE MAKING SYSTEM FOR PRINTING BUILDING MATERIAL

摘要

PURPOSE:To remove the pattern curl of an abstract pattern having a fine pattern, in a plate making process for printing an abstract pattern building material. CONSTITUTION:A unit raw material is read in given picture element density by means of an input scanner 1. Watermark synthesis is longitudinally and laterally effected on picture data of the read unit raw material the given number of times by means of an endless processing part 9. When a pattern curl is produced at endless pattern data, a pattern curl is removed by a pattern curl removing processing part 11 through repetition of operation wherein pattern data in a given position of endless pattern data is replaced with pattern data in other position based on assigned mask data.
