Evaluation Method for Printer Resolution by the Pixel Size Estimation

Abstract

A new evaluation method for printer resolution by the pixel size estimation using one-dimensional random pattern has been developed. By using a one-dimensional random pattern as input data, the frequency response of a printer system was calculated from the density profile of the output image. The resolutions of several printers based on different marking mechanisms were compared by the present method. Psychological sharpness score of portrait images made by printers and simulated halftone prints can be predicted by estimated pixel size and the image contrasts at hi-light and mid-tone of print
