Research on Measurement System of Print Image on Line

Abstract

It be discussed that influence factor and expression ways about print image quality. Density and chroma be used to express image shade and color information for responses print press ink mate and image quality. Image light and shade and color are expressed by ink quantity on print paper in Color print product. The paper discuss print image quantity influence factor and ways expression of quantity about print production, image density and color factor express print image light and shade thereby press ink quantity supply was feedback. CCD-Charge-coupled Device is a kind of semiconductor parts for exploration light distributing. It would catch video frequency for that image formation was better obtained in print product, by image transact soft ware transform light electricity signal into reciprocal image density ,color factor , dot expands superimposition state parameter. For print image in press high speed moving, it is important that speediness exact measure and supervising control image quality. CCD sensor could satisfy dynamic image measurement need. Certainly face CCD could obtain the largest all-around image information, it obtain the more speeding color print image light and shade and color information. CCD sensor measurement system transform software base on print image quality diagnostic density and chroma transform way to charge measure signal into print calling quality expressing way, to come true print quality supervising control.
