    • A full width array spectrophotometer for full width scanning color analysis of color test targets, with one or two substantially linear elongated arrays of closely spaced multiple LED illumination sources of plural different color emissions in a multiply repeated pattern of at least three or four different colors transversely spanning a printer paper path and sequentially illuminated to illuminate a transverse band across a printed sheet moving in the paper path, and a corresponding elongated low cost light imaging bar comprising a parallel and correspondingly elongated array of multiple closely spaced different color sensitive (three or four rows of color-filtered) photodetectors, which imaging bar is positioned to detect and analyze light reflected from the transverse sequentially illuminated band.
    • 全宽阵列分光光度计,用于彩色测试目标的全宽度扫描颜色分析,具有一个或两个基本上线性的细长阵列,其具有多个不同颜色的多个LED照明源,具有至少三个或四个不同颜色的多重重复图案横向 跨越打印机纸路径并顺序照亮以照射在纸张路径中移动的印刷纸张上的横向带,以及相应的细长的低成本的光成像条,其包括多个紧密间隔的不同颜色敏感(三或四个)的平行和相应细长的阵列 行彩色滤波的)光电检测器,其成像条被定位成检测和分析从横向顺序照射的带反射的光。
