Your inquiry to the PNEAC regarding alcohol substitutes was forwarded to the Technical Inquiry Desk. Alcohol substitutes are compounded solutions made from proprietary formulas that the manufactures have not made public, except for the ingredients listed on the MSDS sheets. These ingredients have included butyl cellusolve, and glycol ethers. Some of the fountain solution manufactures may have their MSDS available on-line.
As for your second question regarding how to reduce the water feed on the press with the use of fountain solution, there are many variables. The press and the ink rollers should be properly maintained and in good condition. The water used to mix the fountain solution should be of good quality and not high in mineral content. Re-circulation units that have refrigeration can increase the water's viscosity by cooling the ware to 50-60 degrees F. There are many variables that effect ink/water balance, and this topic is too lengthy to discuss in a correspondence.
