<p>A tire printing device includes a printer head (2), positioned near a rotating tire (1), that ejects and applies coating material, an unevenness detection sensor (3) that detects a predetermined raised/recessed character on the surface of the rotating tire (1) and a PC (10) that sets the origin of rotation of the tire (1) based on a signal detected by the unevenness detection sensor (3) and synchronizes the operation start time of the printer head (2) with the origin of rotation in order to maintain a constant relationship between the position of the raised/recessed character and the position of application of the coating material. Desired printing is performed by the printer head (2) ejecting and applying the coating material onto a surface of the rotating tire (1) after the rotating tire is mounted on a rim and inflated to a regular shape by being applied with an internal pressure.</p> |
