40 Plus™ Base Black
40 Plus Universal Black Base was devised as a product that could be used in a very wide variety of paste ink formulations. It can be used in conjunction with sheetfed litho, heatset web offset, heatset web cover, quickset, small offset, and business forms vehicles. This is the original "40 Plus" base that we have been manufacturing since 1970.
40 Plus contains about 40 percent premium carbon black, a glossy, dense pigment for especially critical printing applications. 40 plus is also low in solvent content, making it acceptable as a component in reduced-VOC ink formulations. Normally, 40 to 45 percent of 40 Plus is the recommended level to use in an ink formula.
