[0002] As is well known, during the production of tire treads in the tire industry, multiple specifications and various patterns are often produced simultaneously. In order to facilitate identification and avoid misusing rubber compounds, when the tread rubber compounds are compounded, different colored lines are drawn on the tire tread rubber compounds and different character marks are sprayed. Information such as specifications, patterns, and whether it is an export tire can be visually distinguished. The color, position, and continuity of the tread character marks and color lines are often judged by manual identification, with low reliability, unable to guarantee the quality of daily production products, and easily flowing into the next process, indirectly causing waste of manpower and material resources.
