摘　　要：研究了EFI Color XF和Heidelberg Prinect Colorproof Pro两种数码打样系统生成特性文件的差异。应用系统的色彩管理功能对打印机进行基础线性化并创建特性文件,从色域、标准测量表中色块的色差和屏幕软打样效果比较两种数码打样系统生成的打印机HP Design Jet5500特性文件。色域包含了印刷标准特性文件的大部分色域,可满足打样及印刷的一般要求。两种系统生成的打印机特性文件在色空间转换后对应色块的色差为2.84,在粉红色和暗调区域色差相对较大。观察者的目视结果平均值为2.1,标准方差为0.568,屏幕软打样的效果介于有细微差异和没有差异之间。实验表明,两种系统生成的特性文件都基本符合数码打样中设备特性文件的要求。The differences between profiles generated from two digital proofing systems- EFI Color XF and Heidelberg PrinectColorproof Pro was researched in this article. The system＇s color management function system was applied to complete basic linearization and create profiles. HP Design Jet 5500＇s profiles created by two digital proofing systems were compared from color gamut, chromatic aberration of color in standard color patches and Soft proofing. The color gamut contained most of color gamut of standard profiles and meet general requirements of the proofing and printing. After the color space conversion , the corresponding color＇ s chromatic aberration of two digital proofing systems profiles was 2.84,chromatic aberration was relatively large in the pink and dark region. The average value of the observers ＇ visual result was 2.1, standard deviation was 0.568 ,the effect of screen soft proofing was between slight difference and no difference. Experimental result shows that profiles generated from two digital proofing systems are basically in accordance with the requirements of profiles in digital proofing equipment.
