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 cm3 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.

Abstract: SUMMARY
The specification pertains to a single or multiple coated printing sheet in particular but not exclusively for sheet-fed offset printing with an image receptive coating layer on a paper substrate. The printing sheet has the property that it can be printed in an offset printing process without spraying a fine powder, usually called offset powder or dust powder, on the sheet as it comes off the press to prevent the ink from transferring to the back side of the next sheet. Also irradiative (UV or IR) or heat drying on the sheet fed press is not necessary and/or the use of overprint varnish is not required. In addition to that, unexpectedly short converting times and times until reprinting is possible can be achieved. Furthermore methods for making such a printing sheet and uses of such a printing sheet are disclosed.

Abstract: A process for improving the barrier properties of a barrier layer in a pulp-based substrate layer having a barrier layer, comprising the steps of providing a pulp-based substrate layer having a layer of an aqueous barrier composition applied to it, and then drying the pulp-based substrate layer having a layer of aqueous barrier composition applied to it to form a pulp-based substrate layer having a barrier layer, such that the moisture content of the pulp-based substrate layer having a barrier layer is below 2.5 % by weight, preferably below 2 % by weight, based on the weight of the pulp-based substrate layer having a barrier layer.
