摘　　要：根据系统间Wiener噪声功率谱的传递理论 ,给出了彩卷颗粒度到彩纸颗粒度的传递规律。在通常扩印条件下 ,彩纸的测定反差和彩卷与彩纸之间的配合参数是传递中的主要因素 ,并试验求取了三种彩卷和乐凯 4型彩纸的配合参数。On the basis of the theory of Wiener noise power spectrum transfer from one system to another,the relationship between the two granularities in a color negative film and its print image is clarified .In common printing condition,the contrast of the print paper and the coefficient representing the coordination between color negative film and paper are key factors .Accordingly,coordination coefficients were determined by making experiments on three kinds of film and Lucky Type 4 color paper.
