PURPOSE: A printing method on a glass surface, and a printed product using thereof are provided to control the etch depth using chemicals for printing on the glass surface. CONSTITUTION: A printing method on a glass surface comprises the following steps: printing letters or patterns on the glass surface using a screen printing method; drying the glass surface; and etching the glass surface without the letters or patterns with a chemical(150) using ammonium fluoride, sulfuric acid, and ammonium fluoride as main components. The etching depth on the glass surface is controlled by using the chemical amount discharged through a nozzle, the transfer speed of the glass surface, and the exposure time of the glass surface to the chemical.
