A preparation method includes the following steps: Step (1): pressing and then drying body powder to form a green brick; Step (2): applying a ground coat on the surface of the green brick; Step (3): inkjet-printing a pattern on the surface of the green brick having the ground coat, and applying an isolation glaze; Step (4): applying a fully polished glaze on the surface of the green brick having the isolation glaze; and Step (5): drying, firing, and polishing the green brick having the fully polished glaze to obtain a hard wear-resistant polished glazed ceramic tile. The phase composition of the fired fully polished glaze is as follows: 10 to 20 percent by weight of corundum, 20 to 30 percent by weight of hyalophane, 0.5 to 1.0 percent by weight of hematite, and 50 to 68 percent by weight of amorphous phase.

A preparation method includes: pressing and forming a ceramic base material to obtain a green body of a ceramic plate; applying a ground glaze on the surface of the green body to cover the base color and defects of the green body; applying a cover glaze on the surface of the green body after applying the ground glaze, wherein the cover glaze contains 0.2 wt % to 0.7 wt % of coloring metal oxide to make the coloring bright; roller-printing patterns on the surface of the green body after applying the cover glaze to produce a flowing cloud effect; and drying the green body with the roller-printed patterns and firing in a kiln. The present invention uses roller printing to print the patterns of cloud effect on the surface of the cover glaze, which form a sharp contrast with the color of the cover glaze, producing a better visually distinct effect.
