色彩管理在数字印刷中应用的实验研究

Research on the Application of Color Management in Digital Printing

为了提高数字印刷的质量,研究色彩管理在数字印刷中的应用。采用Monaco和ProfileMaker两种软件,生成HP Indgo1050数字印刷机在128g/m2有光铜版纸和无光铜版纸上印刷的profile文件,并利用所生成的profile文件对彩色图像进行分色和印刷,从而对色彩管理前、后印刷品的色调再现性进行评价。研究结果表明:利用这两种软件生成的profile文件对彩色图像进行分色,使得数字印刷质量有了明显的提高,尤其是无光铜版纸的印刷质量,增加了图像再现色域;减少了网点扩大,颜色再现更加准确。

The application of color management in digital printing was studied to improve the quality of digital printing. The profile documents of digital printing of two kinds of paper, including 128g/m^2 coated paper and 128g/m^2 matt coated paper, on HP indgo1050 digital printer were generated with Monaco and ProfileMaker software. Color separation and printing was made on the profile documents. The color and tone reproductions before and after color management were evaluated. The results showed that the quality of digital printing is improved obviously after color management, especially on matt coated paper. By using color management, the color gamut is wider than before; dot gain is reduced; tones reproduction become more precise.
