  • Paper having improved print quality and method of making the same
    Publication number: 20030178165
    Abstract: A paper having an improved print quality comprises a paper substrate having a surface with a surface roughness of less than 6 microns and a surface gloss of 5-80% which surface has been coated with a light-weight, low solids content, top coat. The top coat may comprise (i) a rheology modifier/binder component and at least one pigment or (ii) at least one binder coated pigment. The top coat provides a significant improvement to the delta gloss of the so-treated paper.
