Abstract
Abstract A gravure roll and associated coating methods are disclosed that produces a uniform coating gradient on a substrate. The gravure roll comprising a series of cells arranged in circumferential line density sections in which the line densities progressively increase from section to section, and in which the cell volumes progressively decrease within each section, and in which the cell volumes at the end of one section are substantially the same as the cell volumes at the beginning of the next adjacent section.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
215 words
A method of producing a uniform coated gradient on a substrate, the method comprising: applying a fluid coating to a first portion of a substrate by delivering the fluid to the substrate from a gravure roll having a first circumferential line density section of fluid-containing cells having a constant line density, but with progressively decreasing cell volumes within the first circumferential line density section; and applying a fluid coating to a second portion of the substrate adjacent to the portion that was coated from the smallest volume cells in the first circumferential line density section, and from a second circumferential line density section of fluid-containing cells adjacent to the smallest volume cells of the first circumferential line density section and having a constant line density within the second circumferential line density section that is greater than the line density of the first circumferential line density section, but with progressively decreasing cell volumes; and while maintaining the cell volumes in the first circumferential line density section substantially equal to the cell volumes of the second circumferential line density section at the point where the smallest volume cells in the first circumferential line density section are adjacent to the greatest volume cells of the second circumferential line density section in order to provide a uniform coated gradient.
Claim 2
Independent Claim
