    </SPAN>  <SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'"><SPAN style="LETTER-SPACING: 1px">彩色相纸采用减色法成色,它用黄品青三种染料不同浓度的搭配来过滤白光产生不同颜色;而喷墨打印的成色法</SPAN>是加色法。我们用放大镜镜看打印出来的照片,只能看到黄、品、青、红、绿、蓝</SPAN><SPAN lang=EN-US>6</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'">种颜色,它是靠色光的混合产生颜色。<SPAN style="FONT-FAMILY: 宋体; LETTER-SPACING: 0px; mso-ascii-font-family: Times New Roman; mso-hansi-font-family: Times New Roman">如橙</SPAN><SPAN style="LETTER-SPACING: 1px">色</SPAN>就是一定量的黄色光加红色光混合后产生。加色法可以产生更多的颜色(更大的色彩空间),如明亮的红色,为了保证足够的亮度,减色法只能降低品和黄的浓度来实现,这使色饱和度大大下降;而加色法是让黄和品色并列产生亮红色。所以打印照片可以表现非常明亮而鲜艳的彩色云霞,传统相纸就不行。
    </SPAN>  <SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'">照片的最大密度范围也是色彩表现力之一,喷墨打印多用了一种黑色墨,结合优质相纸,可以将照片的密度范围扩大到</SPAN><SPAN lang=EN-US>2.2</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'">,而一般彩色照片只能到</SPAN><SPAN lang=EN-US>2.0</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'">左右。
    </SPAN>  <SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'">色彩表现力也与软件有关,好的软件可以尽量使墨点并列而不是重叠,这就可以产生更鲜艳的色彩,营造出更大的色彩空间。
    </SPAN>  <SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'">最后来看对色彩的控制力。激光冲印机向相纸发射的是</SPAN><SPAN lang=EN-US>3</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'">色窄带色光,或者说是总共只有</SPAN><SPAN lang=EN-US>3</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'">种频率的色光。而所用的彩色相纸却是传统的全色感光相纸。这本来是不匹配的,但经软件的变换,它的表现力还算不错。借助对光源的数字控制,激光冲印机比传统扩印机对阶调的控制更强了一些。当它投射到相纸上时就出了一些麻烦。
    </SPAN>  <SPAN style="FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'">彩色相纸每一种感色层都有两个涂层,它的目的是通过调节这两个涂层的灵敏度和浓度来调节相纸染料密度与曝光量的关系曲线。<SPAN style="LETTER-SPACING: 1px">我们甚至怀疑一些厂家这两个涂层染料的颜色或感色特性可能都有区别,以实现更复杂的色彩控制功能。<SPAN style="FONT-FAMILY: 宋体; LETTER-SPACING: 1px; mso-ascii-font-family: Times New Roman; mso-hansi-font-family:
