Abstract
Abstract A hybrid printing process wherein an ink fountain cylinder is provided with a gravure image carrier portion and an anilox ink metering portion. A cylinder associated with the ink fountain cylinder is provided with a blanket transfer portion and a flexographic image carrier portion. The images carried by the gravure and flexographic portions are imprinted at one or more stations to create a total design on a flexible plastic substrate.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
115 words
Method of printing a moving substrate, comprising providing a first cylinder having ink receiving cells on its periphery, some of said cells defining an image carrier portion for gravure printing and other of said cells defining an ink metering portion for flexographic printing, supplying ink to said ink receiving cells, providing a second cylinder having a blanket transfer portion for gravure printing and a separate image carrier portion for flexographic printing, transferring ink from said image carrier cells to said second cylinder blanket transfer portion and from said ink metering cells to said second cylinder image carrier portion, and transferring ink from said second cylinder image carrier and blanket transfer portions to a moving substrate.
Claim 2
Dependent Claim
115 words
Method of printing a moving substrate, comprising providing a first cylinder having ink receiving cells on its periphery, some of said cells defining an image carrier portion for gravure printing and other of said cells defining an ink metering portion for flexographic printing, supplying ink to said ink receiving cells, providing a second cylinder having a blanket transfer portion for gravure printing and a separate image carrier portion for flexographic printing, transferring ink from said image carrier cells to said second cylinder blanket transfer portion and from said ink metering cells to said second cylinder image carrier portion, and transferring ink from said second cylinder image carrier and blanket transfer portions to a moving substrate.
Claim 3
Dependent Claim
16 words
Method according to claim 1 including removably attaching said image carrier portion to the second cylinder.
Claim 4
Dependent Claim
21 words
Method according to claim 1 including completing a multi-colored design on the substrate at successive printing stations using different colored inks.
Claim 5
Dependent Claim
38 words
Method according to claim 3 including arranging the image carrier cells in parallel lines on the first cylinder at each printing station such that the lines of image carrier cells at successive stations are disposed at different angles.
