Web substrates having wide color gamut indicia printed thereon

摘要

A web substrate having indicia having X colors disposed thereon is disclosed. The indicia are disposed upon the web substrate by a contact printing system adapted to print the X colors upon the web substrate utilizing X-Y printing components. X and Y are whole numbers, 01. Each of the X colors is defined by L*a*b* color values defined by CIELab coordinate values disposed inside the boundary described by a system of equations.

1. A web substrate having indicia comprising at least 2 colors comprising X fluids disposed thereon, said indicia being disposed upon said web substrate by a contact printing system comprising a gravure cylinder having an outer surface for contacting said web substrate and being adapted to print said X fluids each disposed at a position internal to said gravure cylinder and directable to said outer surface and into contacting engagement with said web substrate utilizing X-Y printing components where X and Y are whole numbers, 01, each of said at least 2 colors being defined by L*a*b* color values defined by CIELab coordinate values disposed inside a boundary described by the following system of equations:
{a*=−54.1 to 72.7; b*=131.5 to 145.8}→b*=0.113 a*+137.6 {a*=−131.6 to −54.1; b*=89.1 to 131.5}→b*=0.547 a*+161.1 {a*=−165.6 to −131.6; b*=28.0 to 89.1}→b*=1.797 a*+325.6 {a*=3.6 to −165.6; b*=−82.6 to 28.0}→b*=−0.654 a*−80.3 {a*=127.1 to 3.6; b*=−95.1 to −82.6}→b*=−0.101 a*−82.3 {a*=72.7 to 127.1; b*=145.8 to −95.1}b*=−4.428 a*+467.7where L* ranges from 0 to 100; 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.
