Claim:
A method of removing residual UV-curable ink from components of a printing press, the method comprising the steps of: A. solvating the residual UV-curable ink by applying to the components a composition consisting essentially of: (i) at least one non-ionic surfactant selected from the group consisting of a sorbitan ester, an ethoxylated sorbitan ester, an ethoxylated castor oil, polyethylene glycol ester and an ethoxylated fatty alcohol; and (ii) a carrier consisting essentially of at least one of: (a) at least one organic solvent selected from the group consisting of: (1) the reaction product of phenol with ethylene oxide, (2) the reaction product of phenol with propylene oxide, (3) esters of ethylene glycol or propylene glycol with acids having six or fewer carbon atoms, (4) ethers of ethylene glycol, diethylene glycol, or propylene glycol with alkyl groups having six or fewer carbon atoms, (5) dipropylene glycol monomethyl ether, and (6) propylene carbonate, or (b) D-limonene, or (c) water, wherein the composition has a VOC limit less than 100 g per liter, and B. removing the solvated residual UV-curable ink.
