Abstract
This invention presents terpene-based solvents suitable for use in the processing of a wide variety of photopolymer printing plates. The solvents, which may be terpenes alone, terpenes mixed with organic non-solvents, or terpenes emulsified with water are effective in developing a wide variety of photopolymer printing plates and can produce images superior to those obtained with commercially available solvents currently used in such applications.
