Research on the Printing Suitability of Alcohol-Free Fountain Solution Based on Green Printing

Aiming at fountain liquor is the main source of VOCs in printing, this paper proposes a kind of alcohol-free fountain liquor by adjusting and optimizing the composition. Analyzed the basic theory of printing fountain solution and combined with the wetting principle, we realized the preparation of alcohol-free fountain solution by adjusted and optimized the composition of wetting agent, stabilizer and buffer in fountain solution. Then, the printing test experiment was used to verify the printing suitability of alcohol-free fountain solution. The experimental result shows that the printing suitability of alcohol-free fountain solution can met the printing requirements, it could be used to replace the traditional ethanol fountain solution, and reduce the VOCs emission in the printing effectively.
