Abstract
A contact printing system is disclosed. The contact printing system has a central roll having a plurality of discrete cells disposed upon an outer surface thereof. Adjacent cells of the plurality of discrete cells each have a fluid disposed therein from a respective location internal to the central roll. Each fluid is disposable from each of the cells to a web substrate and provides a resultant color upon the web substrate having a 2-D gamut boundary represented by a defined system of CIELab equations.
Claims18
A contact printing system comprising a central roll comprising a plurality of discrete cells disposed upon an outer surface thereof, wherein adjacent cells of said plurality of discrete cells each have a fluid disposed therein from a respective location internal to said central roll and wherein each fluid is disposable from each of said cells to a web substrate and provides a resultant color upon said web substrate having a 2-D gamut boundary represented by the following CIELab equations:
- {a*=−54.1 to 72.7;b*=131.5 to 145.8}→b*=0.113a*+137.6
- {a*=−131.6 to −54.1;b*=89.1 to 131.5}→b*=0.547a*+161.1
- {a*=−165.6 to −131.6;b*=28.0 to 89.1}→b*=1.797a*+325.6
- {a*=3.6 to −165.6;b*=−82.6 to 28.0}→b*=−0.654a*−80.3
- {a*=127.1 to 3.6;b*=−95.1 to −82.6}→b*=−0.101a*−82.3
- {a*=72.7 to 127.1;b*=145.8 to −95.1}→b*=−4.428a*+467.7
- where L* ranges from 0 to 100.
A contact printing system comprising a central roll comprising a plurality of discrete cells disposed upon an outer surface thereof, wherein adjacent cells of said plurality of discrete cells each have a fluid disposed therein from a respective location internal to said central roll and wherein each fluid is disposable from each of said cells to a web substrate and provides a resultant color upon said web substrate having a 3-D gamut boundary represented by the MacAdam 3-D color gamut.
