The invention relates to the technical field of printing of mobile phone glass protection screens, in particular to an exposure printing technology for a mobile phone glass protection screen. The exposure printing technology comprises the following preparation steps: (A) printing, namely printing a photosensitive pattern on the back surface of a mobile phone white glass sheet by a steel wire gauze, wherein the steel wire gauze is 450-500 meshes; the film thickness of a printing ink is 3-5 microns; and the squeegee thickness is 85-90A; (B) drying, namely drying the printed mobile phone white glass sheet in a dark environment at 130-150 DEG C for 25-30 minutes; (C) primary exposure, namely carrying out exposure on the dried mobile phone white glass sheet under an ultraviolet lamp; (D) developing, carrying out developing for 1.5-3 minutes, cleaning the glass sheet with clean water and drying the glass sheet after an image phenomenon appears; and (E) secondary exposure, namely carrying out secondary exposure on the mobile phone white glass sheet. The exposure printing technology has the characteristics of simplicity in process step, high printing accuracy, clear pattern lines, good stability after image exposure and high scratch resistance.
