The invention discloses a making method of underglazed color-penetrated tile. The making method comprises the following steps: (1) mixing powder and pigment of a brick green body to form colored green body powder, and pressing the mixture through a cloth system and a press to make a green body with required color and texture; (2) drying the green, then spraying lining slurry, wherein the lining slurry contains a color former capable of promoting color development of color-penetrated ink; (3) spraying ink to decorate patterns by using an inkjet machine after the lining slurry is sprayed; (4) spraying a layer of transparent glaze after ink spraying, then burning and polishing to obtain the underglazed color-penetrated tile. According to the making method, a whole texture blank body, conventional ink and color-penetrated ink are combined, so that the patterns on the surface and the textures of the green body of the underglazed color-penetrated tile keep consistent without obvious boundary line. According to the color-penetrated brick prepared by the invention, after slot broaching, beveling and other deep processing, the textures of the green and the patterns on the surface are kept consistent, and the decoration effect is close to the decoration effect of natural stones.
