A reactive digital printing method can be performed with the following steps: 1) applying a primer to a fabric to be printed; (2) applying an ink containing a dye with multi-reactive groups to the fabric to be printed in step (1); (3) steaming and coloring, washing, dehydrating and shaping the fabric in step (2), to obtain a printed product. A related system with a combination of primer, a dye with multi-reactive group, printed fabric produced with the reactive digital printing method and items comprising the printed fabric can also be provided.
