Production process of alumite hot stamping foil

The invention provides a production process of an alumite hot stamping foil, which is characterized in that the alumite hot stamping foil to be slit is provided with a local release layer through a local release process, the local release layer is provided with a release area coated with a release material and a non-release area not coated with the release material, and the non-release area is configured as a slitting knife cutting area. The release layer is positioned and coated through a customized local release process, so that the release layer of the alumite hot stamping foil is provided with the release area coated with the release material and the non-release area not coated with the release material at the same time. In the slitting process, the fragile release layer is prevented from making direct contact with the cutter body to generate fragments, then the situation that falling fragments and powder are adsorbed and accumulated on the surface of a printed product or the surface of an engraving area
