Abstract: An in-depth analysis was carried out of imitating the pattern and color of digital image by jacquard fabric,and the innovative design principle and method of digital jacquard fabric were presented.The design approach is that designing fabric structure on the basis of all-coloring structure,remedying the shortcoming of gray component by twice CMYK separation of digital image,and setting an adjustable range for color selection of threads.The produced digital jacquard fabric is capable of imitating the pattern and color of original digital image.Moreover,for this design method meets the requirement of balanced interlacement,it can be applied to designing digital jacquard fabric with whatever motifs of pattern.And it poses no problem in mass production.
