A paper product having improved printing characteristics and a method of making the paper product. This paper product has a fibrous substrate and top layer of surface enhanced pulp fibers that is integrally coupled to the top surface of the fibrous substrate. The paper product is produced by providing an aqueous slurry formed from a blend of cellulosic fibers and water and at least partially dewatering the aqueous slurry of cellulosic fibers and water to form the fibrous substrate. Subsequently, a surface treatment formed from an aqueous composition of water and surface enhanced pulp fibers is applied to the top surface of the fibrous substrate and thereafter the treated fibrous substrate is dried to form a paper product having enhanced printing characteristics.

Lignin formulations for making light-selective mulch, methods of making such lignin formulations, light-selective mulches comprising substrates treated with lignin formulations, and methods of making such light-selective mulches. Some methods involve preparing aqueous lignin formulations that can be used as coatings that, in turn, can be applied to a substrate, such as a paper web, to form a biodegradable, light-selective mulch. Some such mulches blocks at least some light in the ultraviolet and blue/green ranges (350 nm to 500 nm) of the visible light spectrum to inhibit weed growth below the mulch, while also transmitting light in the red/infrared ranges to heat the soil below the mulch.
