The anilox roll is what sets the flexographic industry apart from other printing discipline.     In gravure the image cylinder makes contact directly with the ink.     In offset and letterpress ink is transferred via smooth rollers to the printing plates. Flexography differs from these processes in that the inks is transferred to the anilox roll, whose …

Why corona is used & how it improves adhesion?Several materials that are printed with flexo technology have nonporous surfaces. The most common of these substrates are polyethylene and polypropylene. These non-porous surfaces have low inherent surface energies, causing them to be non-receptive for bonding with printing inks, coatings, and adhesives. Other materials, such as foils …

INTRODUCTION: Flexo plates are a critical component of the printing system. Printing is a system—viewing plate making in isolation doesn’t address the total print process. A system has multiple components that interact with each other and influence the performance of each. Great plates with the wrong anilox rolls offer nothing to improve quality. Similarly, great …

Consistency = predictability, as printers who’ve done their press fingerprinting homework discover. Flexography has the potential to approach and competitor the print quality of competitor lithography and gravure if flexo converters are willing to pay the price. That price is awareness and control of printing variables. This type of control can be obtained with a …
