The invention discloses a non-alcoholic fountain solution containing a composite surfactant. The non-alcoholic fountain solution comprises the following raw materials in part by weight: 70-85 parts of deionized water, 10-15 parts of kappa-carrageenan, 6-10 parts of amorophophallus konjac, 3-6 parts of tea polyphenol, 2-5 parts of sulfated caster oil, 1-3 parts of sorbitol, 3-6 parts of a pH regulator, 3-5 parts of a composite surfactant, and 1-3 parts of POP glycerin ether. Kappa-carrageenan and amorophophallus konjac are compounded to form a compound, and the compounded as a hydrophilic film former improves the water film persistence, so that the fountain solution has high wettability and permeability when used; kappa-carrageenan-amorophophallus konjac-tea polyphenol microspheres have the characteristics of small mean grain size and slow release of tea polyphenol, and the release of tea polyphenol is slowed during the using process of the fountain solution, so that the oxidation resistance of tea polyphenol is improved greatly, and the using stability of the fountain solution is ensured; and a multielement compounding system of the composite surfactant improves the surface tension reducing efficiency greatly, meets the working solution surface tension requirement of the fountain solution, and is beneficial for enabling the printing process to reach the water-ink balance quickly.
