采用减色法成色原理的彩色感光材料分为透射型胶片和反射型相纸。以往只凭借染料在分光光度计上的一些特性指标判定彩色特征。本文用计算机模拟方法判定彩色还原质量,特别是彩色还原的色彩范围、激发纯度以及选择中性灰的稳定性。透射型彩色胶片在彩色还原范围及激发纯度方面,均比反射型相纸为佳,而选择中
The principle of using subtractive color forming principle of color photosensitive material is divided into transmissive film and reflective photo paper. In the past only by virtue of some of the characteristics of the dye in the spectrophotometer to determine the color characteristics. In this paper, the computer simulation method to determine the quality of color reproduction, especially the color reduction of color range, excitation purity and the choice of neutral gray stability. Transmissive color film in the color reduction range and stimulate the purity, better than the reflective paper is better, and the choice of
