Claim Text:
1. A method for modification of the surface of a film-shaped body, which is either a fibre-containing sheet or a sheet made of a non-fibrous material, said method comprising: dispersing nano-sized polysaccharide fibre particles in a medium essentially composed of water and a polar solvent to form a suspension, applying the suspension onto said surface of a body by a printing method, and adjusting the fibre concentration of the suspension to adjust the viscosity of the suspension to a range that is suitable for said printing, and wherein the viscosity of the suspension, at a shear rate higher than 5 s −1 , is 5-200 mPas, wherein the surface of the sheet is modified to increase the strength properties or printability of the surface of the sheet.
