摘要
A fountain solution for use with a lithographic offset printing press is prepared by admixing fountain etch constituents, water and between about 0.5 and 5 percent by volume of a substitutive additive for isopropyl alcohol. The additive or replacement may be a Carbitol or Cellosolve derivative or mixtures of Cellosolve or Carbitol derivatives, such as phenyl glycol ethers or other organic non-ionic compounds, as for example, n-hexoxyglycol (n-hexyl Cellosolve), n-hexoxydiethylene glycol, (n-hexyl Carbitol), 2-ethyl-1,3-hexanediol, n-butoxyethylene glycolacetate, n-butoxy-diethyleneglycolacetate, and 3-butoxy-2 propanol. The fountain solution free is isopropyl alcohol does not have the adverse toxic and flammable properties of prior art fountain solutions containing isopropyl alcohol.
