METHOD OF SELECTING SUBSTITUTE BASE MATERIAL FOR ACQUISITION OF IMAGE CORRECTION PARAMETER, METHOD OF CREATING IMAGE QUALITY EVALUATION CHART, AND METHOD OF ACQUIRING IMAGE CORRECTION PARAMETER

摘要

PROBLEM TO BE SOLVED: To provide a method of selecting a wrinkle-free substitute base material capable of being used as a substitute for a printing base material when acquiring an image correction parameter for correcting streaks and unevenness which occur in images printed on a limp, translucent printing base material, and also to provide a method of creating image quality evaluation chart using the wrinkle-free substitute base material and a method of acquiring the image correction parameter.SOLUTION: The method of selecting a substitute base material for acquisition of an image correction parameter comprises: calculating the thickness and modulus of elasticity of a wrinkle-free substitute base material, considering that wrinkles are caused by buckling (S12); and evaluating an image on a substitute base material having characteristics equal to or more than those calculated to determine the thickness of the substitute base material on which images are not blurred (S14); and then selecting a substitute base material on which wrinkles and blurring do not occur (S16). An image quality evaluation chart is created using the substitute base material to acquire an image parameter.
