Alcohol, particularly Isopropyl Alcohol (IPA), plays a crucial role in the offset printing process. When IPA is mixed with fountain solution water, the surface tension of the water is lowered while maintaining its flow properties. This reduction in surface tension enhances the water's ability to wet the surface, thereby enabling the formation of a thin water layer.
However, it is important to note that the amount of alcohol added should be limited. Excessive alcohol can cause issues with ink, water, plates, and even paper. Alcohol addition should be less than 12% of the total mixture (percentage may vary depending on the brand of each fountain solution).
With the addition of alcohol, flow properties improve, allowing for the production of a thin water layer. Additionally, mixing isopropyl alcohol accelerates evaporation, reducing the amount of water on the plate's surface.
