摘　　要：为解决基于网点图像的色彩仿真提花织物网点形状局限于简单几何形问题,提出一种异形网点库设计方法。以排列角度、单位网点的大小、网点形状及其生成路径为设计要素,创建异形网点库并设计织造织物色卡和灰度仿真提花织物,同时设计相应的影光组织织物色卡和提花织物作为对比样。对织物色卡进行测色,以及对提花织物图像明度数据完成了分区统计。结果表明:异形网点织物较影光组织织物具有更稳定的灰度仿真性能;网点形状的饱满程度是调节异形网点提花织物灰度仿真效果的关键因素。异形网点库的设计与应用,在提升单层黑白提花织物灰度仿真稳定性的同时,增添了提花织物的设计趣味性。Objective Aiming at the situation that the dot shapes applied to the grayscale simulation jacquard fabric are limited to simple geometry,a special-shaped dot database design method was proposed,and the reproduction performances of the created special-shaped dot databases in the design of jacquard fabric were compared and investigated,attempting to provide a new method for promoting the color simulation of jacquard fabric design technology.Method Four specially-shaped dot databases were designed by graphic generation technology.One group of fabric color cards showing grayscale from black to white gradient changed and four jacquard fabric samples representing an image were woven by applying the special-shape dot databases.All fabric samples were interwoven from one set of white warp and black weft yarns.The materials of warp and weft threads were both 23.3 dtex×2 silk,and the warp and weft filling density were both 1100 threads/(10 cm).By comparatively analyzing the average lightness differences between the values of the fabric color cards and the original grayscale color,and between the value of the jacquard fabric samples and that of the original image,the grayscale simulation feature of the special-shape dot databases in the color simulation design of jacquard fabric were explained.Results The mean value of the fabric color cards woven using the tree-shaped dot database and the original grayscale from the black to the white were calculated,respectively,and the difference between them was only 1,which indicated that the grayscale simulation performance of the tree-shaped dot database was excellent compared with the another six group of fabric color cards applying frequently-used shaded weave databases in total(Tab.1).In order to further analyze the color simulation capability of the special-shape dot databases for rending complex image,six jacquard fabric samples were produced by using the four special-shape dot databases and two shaded weave databases,respectively.All figured jacquard fabric samples are scanned
