PURPOSE: A paint composition for etching is provided to enhance safety, stereoscopic perception, and visual representation by excluding use of solvent resin and ceramic resin. CONSTITUTION: A paint composition for etching comprises one or more from a group including gelatin component, hydrofluoric acid(HF), ammonia solution(Na4OH), fluorinate antimony(SbF3), glycerin(C3H3(OH3)), potassium fluoride(KF), sodium fluoride (NaF), P.P.G.#4000(HCOCH2CH2)n. An etching printing method of glasses using the paint composition for etching comprises the following steps: maintaining inner temperature before printing as 30-40 deg. Celsius and humidity as 60-80% and washing a glass; installing a silk screen on a silk screen printer; printing the glass surface with non-glossy paint by injecting the non-glossy paint on the silk plate; welding the non-glossy paint to the glass by drying in a drying furnace at 30-50 deg. Celsius for 20-30 minutes; and washing the dried non-glossy glass with water.
