The present invention relates to a ceramic printing ink composition having an antibacterial function and, more specifically, to a ceramic printing ink composition, which is prepared by comprising deionized water, propylene glycol, a propylene glycol methyl ether acetate (PMA) solvent, a propylene glycol methyl ether (PM) solvent, isopropyl alcohol (IPA), a dispersant, a pigment, a flow additive and an aqueous antibacterial composition such that printing on a ceramic coating layer can be strongly and readily carried out. Additionally, an aqueous antibacterial composition, which is a prior application of the applicant of the present invention and is registered (Korean patent registration No. KR 10-0999170), is contained in the ceramic printing ink composition, thereby allowing the ceramic printing ink composition to have an antibacterial function. In addition, printing is carried out, by pad, screen or stamp printing, between ceramic coating layers or on an upper end thereof when printing a pattern by using the ceramic printing ink composition, and more specifically, ceramic coating (sol-gel) layers (1-coat, 2-coat, 3-coat and the like) are formed, printing is applied after the set-to-touch drying thereof, and then the coating layers heat-cured simultaneously, thereby reinforcing binding and adhesive forces such that stronger and easier printing is enabled.
