This is a powerful modifier for reducing the body and tack of oil based printing inks. Add 5-10% by volume for most applications. Miracle Gel Reducer makes hard-to-wipe etching inks easier to wipe. In litho inks, it decreases tack without increasing greasiness. (This is helpful when printing large flats that tend to show roller marks.) When added to relief inks, it reduces the tendency of soft papers (like traditional Japanese) to stick to the wood or linoleum. Made from clear mineral oil, it will not change an inks color.
