Devicelink技术在数码印花追样的应用研究

Application of Devicelink technology in chasing sample of digital printing

为了提高数码印花追样质量,文章通过主、客观评价法,对基于ICC Profile的ICC Devicelink技术追样、基于Device Profile的Devicelink技术追样,以及使用标准ICC色彩追样转换过程的追样效果分别进行对比分析。研究表明:基于ICC Profile的ICC Devicelink技术的追样效果与原图打印效果相近,相较基于Device Profile的Devicelink技术追样更适合应用在纺织品数码印花追样过程中。此外与使用标准ICC色彩转换过程追样相比,运用Devicelink技术包含K保护追样,可以使单纯黑色尽量避免混入其他杂色,较好地保护黑色实地。而且基于ICC Profile的ICC Devicelink技术包含黑保护追样,黑保护效果最好,可以更好地保留黑色文本不被转换成CMY,使黑色不偏色。

In order to improve the quality of chasing sample in digital printing, the research compares and analyzes the chasing effects of the ICC Devicelink technology based on ICC Profile, the Devicelink techn ology based on Devicelink Profile and the standard ICC color conversion process through subjective and objective evaluation method. The research shows that the chasing effect of Devicelink technology based on ICC Profile is similar to the original printing effect and more suitable for application in textile digital printing process compared with the Devicelink technology based on Device Profile. In addition , compared with the chasing sample of the standard ICC color conversion process, Devicelink technolog y contains K protection for chasing, which can preferably protect black filed by prevent mixing other colors into pure black. Furthermore, the ICC Devicelink technology based on ICC Profile contains K protection for chasing, showing the best black protecti on effect, and it can better keep the black text not be converted into CMY, keep the color black.
