Abstract:
A method for creating an image in a photosensitive material utilizing a raster scan exposure system comprising the steps of:(a) creating an initial data file comprising information defining the desired image to be produced in said photosensitive material, (b) determining the amount of overscan for inside corner locations of said initial data file, (c) creating a first set of intermediate data patterns by positively sizing said data file in horizontal and vertical directions by said determined amount of overscan, (d) creating a second set of intermediate data patterns by negatively sizing said first set of intermediate data patterns in horizontal and vertical directions by said determined amount of overscan, (e) performing boolean operations on said first and second set of intermediate data patterns and said initial data file to generate a modified data file having said determined amount of overscan at inside corner locations, and (f) scanning a beam of radiation generated by said exposure system across the photosensitive material in accordance with said modified data file.
