Abstract: A method for printing the surface of a chair base by water transfer printing comprises the steps of: a. pretreating the object to be printed; b. applying base coat or interface coat; c. drying and baking; d. putting transfer paper in a water transfer tank; e. applying activator; f. transfer printing; g. washing with water; h. drying: and i. applying finishing coat. The chair base printed with patterns by water transfer printing is improved both in aesthetic appearance and wear resistance. Further, during the printing process, the printed patterns can be protected by the surface film.
