The invention discloses a thermal transfer method and system. The thermal transfer method comprises the following steps: S1, coating the surface of an object to be decorated with a thermal transfer film; S2, putting the surface, which is coated with the thermal transfer film, of the object to be decorated into a liquid medium with preset temperature and preset pressure intensity for preset time; S3, taking out the object to be decorated, and stripping off a base material film of the thermal transfer film. According to the thermal transfer method, the liquid medium replaces a conventional thermal pressing die, so that the flexibility of a thermal transfer process is improved.
Description
technical field [0001] The invention relates to the field of transfer printing films, in particular to a thermal transfer printing method and system. Background technique [0002] The existing thermal transfer process uses thermal transfer equipment + thermal transfer film. After positioning the product to be decorated by positioning the mold, the thermal transfer equipment is equipped with a thermal pressing tool that is similar in shape to the decorative product. One upper pressing tool is used for one printed product, and the thermal transfer film is hot-pressed to the product to be decorated by pressure (5KG pressure) and heating (120-280 degrees Celsius). Because of the action of pressure and heat, the ink on the thermal transfer film is transferred to the substrate to be decorated, and the substrate film of the thermal transfer film is removed to achieve the decorative effect. [0003] However, for different decorative products, it is necessary to equip hot pressing t...
