模块组合全显色结构提花织物设计与仿色优化比较

Comparative research on color simulation optimization of jacquard fabric based on modularized compound full-color structure

为提升提花织物对特殊色相图像的色彩仿真效果,提出一种基于组合全显色结构的模块化设计方法。以2组基本组织构成的组合全显色结构为基础模块,与2种不同辅助模块进行组合设计,以满足奇数组显色纬对组合全显色结构的多样化设计需求。以4幅绿色调印刷品图像为色彩仿真对象,采用2种模块组合全显色结构配合五组显色纬,进行色彩仿真提花织物样品的设计与织造。通过对印刷品与织物样品图像的测色数据的色差比较分析表明,2种五组显色纬提花织物在绿色区域的红绿值色差分别平均降低了44.22%、37.78%,而总色差则分别平均降低了16%、10.55%,使提花织物色彩仿真度得到显著改善。

In order to improve the color matching in jacquard fabrics for given color images,a modular design method of combining the full-color structure was proposed in this research.Based on the compound full-color structure composed of two basic weaves,combinations were made with two different groups of supplementary weave modules to form the variable full-color structure to meet the design needs of jacquard fabrics that require odd groups of color wefts.Using 4 green print images as color simulation objects,two modularized compound full-color structure were used,and the jacquard fabric samples were produced in conjunction with five seTSof color wefts.By comparing the color difference between the color measurement data of the printed image and the fabric samples,it was found that the red-green color difference of the two groups of fabric samples in the green area of the image were reduced by 44.22%and 37.78%respectively,while the total color difference decreased by 16%and 10.55%respectively.All these indicates that the color matching of the jacquard fabrics were significantly improved.
