Abstract:
The present invention relates to a method of making a paper product having Improved printing characteristics. This is achieved by forming a fibrous substrate, and applying a surface treatment which comprises an aqueous composition. Notably, the aqueous composition includes surface enhanced pulp fibers, with the placement of the surface enhanced pulp fibers optimizing their functionality, with surface placement by use of a paper machine size press desirably facilitating a reduction in the typical starch usage. The present method comprising the steps of providing a aqueous slurry comprising a blend of cellulosic fibers and water and dewatering the aqueous slurry of cellulosic fibers and water to form a fibrous substrate. The present method further includes applying a surface treatment to the fibrous substrate, wherein the surface treatment comprises an aqueous composition including surface enhanced pulp fibers, to form a treated fibrous substrate, and thereafter drying the treated fibrous substrate to form a paper product having enhanced printing characteristics.

Claim (Index 1):
A method of making a paper product having improved printing characteristics, the method comprising:\n providing an aqueous slurry comprising a blend of cellulosic fibers and water; at least partially dewatering the aqueous slurry to form a web of fibrous substrate having a surface and defining gaps; applying a treatment to the surface of the fibrous substrate to form a treated fibrous substrate, wherein the treatment comprises an aqueous composition comprising surface enhanced pulp fibers; and drying the treated fibrous substrate to form a paper product; wherein the surface enhanced pulp fibers comprise refined hardwood pulp fibers that have been refined in a refiner comprising a pair of refiner plates having a bar width of 1.3 millimeters or less and a groove width of 1.6 millimeters or less with the refiner operated at a specific edge load less than 0.2 Ws/m; and wherein the surface enhanced pulp fibers have a length-weighted average fiber length of at least about 0.3 millimeters and an average hydrodynamic specific surface area of at least about 10 square meters per gram, and wherein the length weighted average length of the surface enhanced pulp fibers is at least 60% of the length weighted average length of the hardwood pulp fibers in their unrefined state prior to being refined in the refiner.
