The present disclosure relates to the field of ceramic tiles, in particular, to a ceramic tile decorated with a dry particle ink and a manufacturing method thereof. The manufacturing method comprises the steps of A: decorating a ground coat; B: decorating to form a pattern; C: drying firstly; D: embellishing with dry particles; E: spraying a protective glaze; and F: firing. The manufacturing method has simple operation steps and convenient control, simplifies the process flow, improves production efficiency, and reduces production difficulty and production cost. By spraying with the dry particle ink, jet printing is carried out on a designated position on the surface of a green body, so that the texture sprayed can accurately correspond to the pattern-decorated texture, and the uniformity and adhesion of the dry particle distribution on the surface of the green body can be improved.
