The printing process on cotton fabrics by using the printing color paste containing grape pigment is as below: printing, drying, steaming and posttreatment. The printing process on silk fabrics by using the printing color paste containing grape pigment is as below: adjusting the pH value to 4-5, printing, drying, steaming and posttreatment. The cotton fabrics and silk fabrics printed by grape pigment have soft color, good color fastness and a health care function; the grape pigment printing is in line with the ecological and environmental requirements; different mordants can enrich the tone of the printed products; and the environmentally friendly moisture absorption cosolvent glycerin makes the production process more environmentally friendly.
