Halftone Base is a BALANCED clear ink base that is similiar to Extender Base except it DOES NOT HAVE inert opacifying materials or bulking agents. It is designed to make plastisol ink more transparent and usually allows the ink to penetrate further into the garment. Halftone Base will greatly diminish the opacity of plastisol and may reduce the viscosity. Halftone Base can be used to make an ink more transparent. This is helpful when trying to achieve secondary colors in 4-color process printing.
