The invention discloses a mixed printing ink. The mixed printing ink is prepared from the following raw materials in parts by weight: 55-65 parts of a water-based ink, 15-25 parts of an oil-based ink and 15-25 parts of a diluent. According to the mixed printing ink, the water-based ink and the oil-based ink are mixed according to a reasonable proportion, so that the glossiness of the ink is increased, and printed patterns are even, smooth and exquisite. The aodpted materials are no-benzene series materials, do not contain volatile poisonous deionized water, has a good printing effect, is strong in attachment firmness, incombustible, unexplosive and nontoxic, causes no harm to printing workers, avoids environmental pollution to the atmosphere and has good environmental protection performance; as a wear-resistant additive is added, a printed ink layer has a very small friction coefficient, and accordingly, the wearing resistance of the ink is greatly improved; the cost is relatively low, the ink layer attachment firmness is strong, and the mixed printing ink can resist rubbing and scratching, and is high in glossiness, good in wearing resistance, quick in drying and excellent in product quality.
