Zusammenfassung:	The invention relates to the technical field of curved-surface cover plate production, and particularly discloses a cover plate hot-bending and protective forming process. The over plate hot-bending and protective forming process comprises the following steps: coating printing ink on a cover plate part to form a printing ink protective layer; placing the cover plate part coated with the printing ink protective layer into a hot-bending mould, utilizing hot-bending equipment to treat the hot-bending mould for enabling the cover plate part in the hot-bending mould to form a curved-surface protective cover plate; and cleaning the printing ink protective layer on the curved-surface protective cover plate, and enabling the curved-surface protective cover plate to form a curved-surface cover plate. Through protection, in a cover plate hot-bending forming process, of the printing ink protective layer, pressing marks, stamping marks and surface spots formed by extruding the cover plate via thehot-bending mould are red
