wherein, the specific formula of the blank and the adopted raw materials are not specially limited, and the technicians in the field can select the blank according to the corresponding production conditions; preferably, a porcelain brick blank formula is adopted, and the thermal expansion coefficient of the blank is matched with the glaze so as to ensure that the defect of glaze cracking is avoided.
Preferably, the ground glaze slip is prepared by mixing 70% of XKB-938A and 30% of XKB-954; the XKB-938A is prepared from the following raw materials in parts by weight: 35-40 parts of potash feldspar, 15-18 parts of calcined alumina, 6-9 parts of kaolin, 5-8 parts of wollastonite powder, 6-8 parts of quartz and 8-10 parts of calcined kaolin; the XKB-954 is prepared from the following raw materials in parts by weight: 18-22 parts of albite, 25-30 parts of potassium feldspar, 4-7 parts of calcined alumina, 6-9 parts of kaolin, 5-8 parts of wollastonite powder, 10-15 parts of quartz and 5-8 parts of calcined kaolin.

Furthermore, the proper glazing amount can ensure that a colored glaze layer with uniform color is formed in the permeation process of the colored glaze slurry, and the color of the colored glaze layer is lighter than that of the ceramic tile by 50-70%.
Preferably, the specific gravity of the colored glaze is 1.45-1.50g/ml, the flow rate is 19-23 seconds, and the glazing amount of the colored glaze is 115-125g/m2。

Preferably, the ink-jet printing is carried out at a temperature of between 40 and 60 ℃; further preferably, the ink-jet printing is carried out at the temperature of 40-50 ℃, and the ink-jet printing temperature is controlled to accelerate the absorption speed of the brick surface to the ink-jet ink, reduce the ink halation effect and enable the permeation line to be more vivid.
Placing the blank obtained in the step (4) for a preset time to enable the decorative pattern to penetrate into the colored glaze layer;
preferably, the blank is placed for 1-3 minutes to allow the inkjet ink to fully penetrate into the colored glaze layer; further preferably, the blank is left for 1-2 minutes, and the production efficiency is affected by too long holding time.
(6) Applying a cover glaze on the surface of the blank to form a cover glaze layer;
the process of applying the overglaze to the surface of the blank is not particularly limited, and the overglaze spraying, the glaze throwing, the screen printing and the like can be adopted. Preferably, in this step, a glazing manner of glaze pouring is adopted, specifically, the glaze pouring is carried out by using a bell jar. The bell jar glaze pouring can effectively ensure the even distribution of glaze, and can recycle redundant glaze slip, thereby saving the cost.

(7) Drying the green body obtained in the step (6);
preferably, after drying, the water content of the green body is less than or equal to 1 percent, and further preferably, the water content is less than or equal to 0.8 percent; because the glaze of the ceramic tile is thick, the ceramic tile needs to be fully dried before entering a kiln to be fired so as to prevent the defects of cracking of the surface of the ceramic tile and the like.
(8) And (5) firing the blank obtained in the step (7) to obtain the full-plate dark-color ceramic tile.
Preferably, the sintering temperature is 1155-1200 ℃, the sintering period is 55-65 minutes, and the heating rate is 5-15 ℃/minute. The ceramic tile is sintered at the temperature, so that the green body and the glaze can be fully sintered, and the ceramic tile with stable performance is obtained.
It should be noted that, in the existing inkjet bleeding technology, inkjet ink is directly sprayed on the ground coat layer, and for the ceramic tile with the deep color full-page pattern, a large amount of inkjet ink causes the ceramic tile to be easy to have a string between the nozzles, which affects the overall quality of the ceramic tile. The invention adopts the process of combining the roller and the ink jet to prepare the full-plate dark-color ceramic tile, can effectively solve the problems of ink jet drawing of dark-color marble patterns and the defects of yin and yang colors, and ensures that the patterns are clear and have strong layering.
