Quantitatively, pigments are the principal constituent of any coating color, binders being used in relatively small amounts. For every 100 parts pigment, there are typically about 5-20 parts binder and 0.1-3 parts of other additives. Coating color compositions common in both North America and Europe for sheet-fed offset and rotogravure printing processes are listed in Tab. 4-2.

Wash deinking often used for flexo-printed waste and in older tissue mills, large water consumption. Flotation deinking for oil-based printings such as offset and rotogravure, technology from the mining industry. 

For heat offset printing, lower roughness is required, i.e. Bendtsen values of approximately 100 ml min . To meet this requirement, on line soft calenders with a total of two nips are used, so that each side of the web contacts a heated roll once. With a suitable layout - linear load, roll surface temperature - even rotogravure-capable SC-B papers (see below) can be produced...
