密度(Density)在影像和印刷行业中用来表示基本色的深度,相对于空白纸基来说,密度值越高代表着对应的颜色越深、越饱和。黑白影像在同样纸自的情况下,最大密度值越高越能实现更大的明暗范围,还原更多的层次和细节。但是最大密度值的获取,或者说是设定,是有条件的。影像行业的最大密度要建立在保证线性化的基础上,否则将造成暗调层次并级的品质故障。不久前,爱普生(中国)有限公司与美国爱丽色公司合作,进行了一次爱普生打印输出照片与传统银盐冲印照片进行了最大密度的对比测试。首先,让我们了解一下密度的测量原理和测量方法。测量密度采用的仪器是密度计,分为透射密度计和反射密度计,前者 Density is used in the imaging and printing industries to denote the depth of a base color, which, relative to a blank base, means that the darker and more saturated the corresponding color is. Black and white images in the same paper since the case, the higher the maximum density of the more the more the scope of light and shade to restore more levels and details. However, the maximum density of access, or set, is conditional. The maximum density of the video industry to be based on the guarantee of linearity, otherwise it will result in dark level and level of quality problems. Not long ago, Epson (China) Co., Ltd. and the United States love the color company, conducted an Epson printout photos and traditional silver print photos conducted the highest density comparison test. First, let’s take a look at the density measurement principle and measurement method. Density measurement instrument used is a density meter, divided into transmission densitometer and reflection densitometer, the former
