Water-based inks represent an exciting trend in the world of packaging industry
and provide a technology for printers to eliminate VOCs (volatile organic
compounds) emissions. There has been significant growth in the usage of water-
based ink in the flexo packaging market, such as labels, corrugated products,
paper products, and some of the polyethylene products. Over the years, ink
manufacturers have worked to improve ink properties in order to achieve better
print quality.
Rheological properties have major impacts on flow of inks and are fundamental
in determining ink transfer in flexo printing. Of special interest are how water-
based flexo inks behave and whether the rheological characterization has any
power in predicting press performance of inks. In this paper, measurements of
rheological properties of six water-based flexographic inks are discussed. A
Flexo trial was performed on a three-color ComCo Commander flexographic
