The invention relates to a porcelain full-body archaized brick and a preparation method thereof. The preparation method of the porcelain full-body archaized brick comprises the following steps that (1), color blending is conducted on green body powder, and the green body powder is prepared into at least two kinds of colored powder; (2), the at least two kinds of colored powder is subjected to material distribution according to a preset textured pattern so that the full-body is provided with each colored powder, pressing forming is conducted, and a green body is obtained; (3), ink jetting and positioning printing are conducted on the green body according to the preset pattern; (4), an enamel layer is applied to the surface of the green body; and (5), the whole green body is fired to obtainthe porcelain full-body archaized brick. Through combination of green body material distribution and ink jetting positioning printing, a surface glaze layer is removed, the forming effect of the porcelain full-body archaized brick combines a stereo effect of the green body texture and the rich colors of the ink jetting printing, and a ceramic product which is equal inside and outside, high in stereoscopic sensation and rich in layer is formed.
