The invention relates to the field of ceramic crafts, in particular to a production method of simulation plaque, comprising the following steps of: 1, kneading porcelain clay into a flow shape and then biscuiting at 1,270-1,330DEG C; 2. adding a layer of transparent base enamel with the sintering temperature of 1,080-1,150DEG C on a biscuited blank; 3. spraying pigments of various colors on the transparent base enamel; and 4. coating a layer of transparent base enamel with the sintering temperature of 1,080-1,150DEG C and carrying out glaze firing at 1,080-1,150DEG C to obtain a finished product. Compared with the prior art, because the colorization is carried out below the glaze, the plaque product has the advantages of smooth surface, abundant colors and layers, excellent simulation effects, bloom like real flowers and higher grade.
