An automated method for evaluating the edge quality of cut-sheet papers

摘要

The precision,sharpness,and cleanliness of the edges of cut sheet papaers has a dramatic effect on the performance of the papers in copiers and printers.Several manual methods have been used to evaluate the cut quality of such papers.Apogee Systems in conjunction with Georgia pacific's Ashdown Mill have developed an automated method and instrument for measuring the edges of GP's cut-sheet papers.using an 11 X 17 - inch tabletop scanner,a PC,and specialized image analysis software (Spec Edge) ,the system provides a variety of quality-related measurements.This presentation describes the features,the measuremnts generated,and an engineering comparison to human visual evaluations.
