One thing that has failed to be mentioned regarding the vapor pressure of the
fountain solution issue is that water has a vapor pressure as well. At 25 C,
water has a vapor pressure of about 24 mm Hg. In other words, the vapor
pressure that this fountain solution exhibits is probably just the vapor
pressure of water. The vapor pressure of the alcohol substitutes commonly used
are less than 1 mm.
