<p>A method for more easily marking an optical recognition code is accomplished. First, a red ribbon-shaped thread 30r, a green ribbon-shaped thread 30g and a blue ribbon-shaped thread 30b are woven into a fabric mark object 28 in three lines. Next, black embroidery patches 32a to 321 are provided in predetermined regions of the ribbon-shaped threads 30r, 30g and 30b by embroidering to partially cover and thus mask the ribbon-shaped threads 30r, 30g and 30b. Through the above two steps, a color bit code is marked on the fabric mark object 28 by exposing the colors of the portions wherein the black embroidery patches 32a to 321 are not provided.</p> |
