Considering the characteristics of large-particle silica sol and small-particle silica sol and their applications in offset printing, the following conclusions can be drawn:
• In printing tasks that require highly fine patterns and detailed expressions, small-particle silica sol is more suitable due to its high dispersibility and permeability.
• In occasions where printing accuracy is not required, or in printing processes that require adjusting ink viscosity and improving ink performance, large-particle silica sol may be a suitable choice.
Therefore, when choosing silica sol, it should be decided whether to use large-particle or small-particle silica sol based on specific printing needs and process requirements. If fine printing effects and high-quality prints are required, small-particle silica sol is a better choice.
