Due to lower viscosity of alcohol substitutes, less dampening fluid measurement or by extrusion using the measuring roller is measured on a continuous contact dampening roller, so it is necessary to increase the dampening roller speed, resulting in many press operators mistakenly conclude that the You must use more water when using alcohol substitutes printing fountain solution. In fact, to improve the viscosity of the solution to some extent, so that the fountain solution is cooled. 3. The ability to quickly wetting surface tension plate and a thin water film is formed on the fountain solution offset two key requirements, mainly by the surface tension of the dampening solution determined. It is widely believed that the low surface tension of fountain solution can be well used in high-speed printing, but in Europe there are reports to the contrary. It is understood that the alcohol substitutes can be achieved with low surface tension printing operations personnel are accustomed IPA has.
