Inkjet printing technology including the inks and pretreatment, printing, post-treatment processing used for cotton fabric is introduced. According to the individuality, fashionability and diversity of design, combining modern computer application technology, the design rules involved in space pattern, abstract pattern, fractal geometric pattern, classic yarn dyed grid pattern and tranditional national costume pattern are also presented. The author concluded that the neoteric printing technology based on ink-jet printing would substitute for tranditional printing way and become one of the main processing methods to produce high definition, high simulation and high quality cotton fabrics with a broad development prospect.
