What the poster is talking about is finished shoes or semi-finished products. If the uppers and soles are separated and processed separately, the finished shoes will be more difficult to handle.
If the inner lining of the shoe upper and the sole are not formed, the model printed on the inner lining can be screen printed or high-frequency transfer printed; the sole trademark can be screen printed, transferred or laser-printed.
The inner trademark of the finished shoes can only be made on transfer paper first, then heated with a manual electric iron to press the transfer model, and the model content is printed on the inner. The sole trademark can only be sent to the laser trademark manufacturer. Dealt with it.
