Performance of kaolins in some specific paper grades Woodfree topcoating Woodfree papers use high levels of calcium carbonate for brightness. Increasingly, engineered carbonates (GCCs or PCCs) are being used to increase light scatter. One drawback of these pigment designs is that the increased porosity can lead to fast ink setting and reduced print gloss. Adding
