Claim 1:
2. The method of manufacturing a window-glass having a print pattern for a smartphone camera of claim 1,
wherein the print pattern formation process 400 comprises: a pattern printing step 410 for forming a print pattern layer by printing a pattern with a thermosetting color ink on a back surface of the glass sheet 12 with a print mask having a print pattern formed thereon; a print multi-deposition step 420 for forming a pattern multi-deposition layer 42 on an upper surface of the print pattern layer of the glass sheet 12 after the pattern printing step 410; a base printing step 430 for forming a base print layer 43 on an upper surface of the multi-deposition layer except for a central transmission area of the glass cell 13 through which light is transmitted; and a pattern multi-etching step 440 for removing by etching the pattern multi-deposition layer 42 formed in the central transmission area of the glass cell 13 on which the base print layer 43 is not formed through the base printing step 430.
