Abstract
The present invention provides cleaning solutions for removing ink, coating, varnish, adhesive, etc. residue from printing equipment. The cleaning solutions of the present invention comprise one or more solvents, preferably selected from acetoacetates, alcohols, glycol ethers, glycol esters, terpenes, and water, and are preferably free of surfactants. The cleaning solutions of the invention have a relative evaporation time (RET) of less than 60 seconds, and a ratio of the RET to the radius of the sphere of solubility of the resin in the ink to be removed of less than 6.
