Alcohol Replacers and IPA

Alcohol replacers were developed and generally accepted into use in the 1970’s as a replacement for isopropyl alcohol in the press ready mixture.

Many printers choose to eliminate the major disadvantages of isopropyl alcohol, including its health and environmental concerns, the increased cost of constant replenishment and its flammability.
