Abstract: A printing sheet is described comprising a substrate and, on at least one side of the substrate, an image receptive coating layer with a cumulative porosity volume of pore widths below 200nm as measured using nitrogen intrusion methods of more than 0.006 cm 3 per gram paper. In particular in the context of printing sheets with high-gloss this particular porosity distribution leads to a quick and easily adjustable ink setting behaviour. Additionally a method for manufacturing such a printing sheet is described using organic, i.e. polymer and inorganic particulate pigments of fine particle characteristics.
