The invention discloses a printing technology for forming metal glaze textures on a ceramic glaze. The printing technology comprises the steps that blank making raw materials are weighed, ball milling and pulping are carried out, and slurry is dried into micro powder to pass a sieve; the sieved powder is pressed into a green brick, powder particles on the surface of the green brick are brushed away, and the green brick is dried; the priming glaze is sprayed on a dried ceramic blank body, screen printing plate printing is carried out on the priming glaze, the thickness of the printing glaze ranges from 0.5 mm to 1 mm, and the metal glaze is printed on the empty space of the screen printing plate printing through the gravure, or letterpress printing or lithoprint method; the ceramic blank body on an upper metal glaze is placed in a high-temperature kiln to be sintered, and edge grinding is carried out after cooling. According to the processing method, the glaze printing can be carried out under the premise of the green brick flatness, the processed ceramic glaze cannot be cracked, the green brick is higher in strength and not prone to fracture, and a good integral appearance effect is achieved.
