Web substrates having wide color gamut indicia printed thereon

摘要

A web substrate having indicia with L*a*b* color values disposed thereon is disclosed. The indicia disposed upon the web substrate are defined by CIELab coordinate values disposed inside the boundary described by the MacAdam 3-D gamut and CIELab coordinate values disposed outside the boundary described by the Kien 3-D gamut.

1. A web substrate having indicia disposed thereon by a contact printing system comprising a gravure cylinder having an outer surface for contacting said web substrate, said indicia comprising L*a*b* color values, said indicia being formed from at least two fluids disposed at a position internal to said gravure cylinder and directable to said outer surface and into contacting engagement with said web substrate, said L*a*b* color values of said indicia being defined by CIELab coordinate values disposed inside a boundary described by the MacAdam 3-D gamut and CIELab coordinate values disposed outside the a boundary described by the Kien 3-D gamut, and wherein said indicia disposed upon said web substrate has a dot gain of less than 20% and a 1:1 relationship between input halftone density and output halftone density.
