Anilox Rolls and Plate Mounting in Flexo Printing: Controlling Ink Transfer on Paper Packaging

Flexo print quality is set by ink transfer, which the anilox roll meters and the plate applies. An anilox roll with the right cell volume and line screen delivers consistent ink film, while accurate plate mounting prevents registration drift and mottling. Controlling both produces crisp, repeatable print on paper packaging.

The Scenario: Ink transfer sets print quality

Flexo printing faces three challenges:

Pain Points

• Inconsistent ink film causes color variation and mottling across the run;
• Poor plate mounting leads to registration drift and blurry print;
• The anilox roll must be matched to the ink and substrate for correct coverage.

The Solution: Three flexo-printing solutions

Three practices deliver consistent print:

1. Matched anilox cell volume The right cell volume and line screen deliver a consistent ink film.

2. Accurate plate mounting Precise plate mounting prevents registration drift and mottling.

3. Ink-and-substrate matching Anilox and ink are matched to the substrate for correct coverage.

The Result: Crisp, repeatable print

With controlled ink transfer, packaging prints crisply and consistently run after run. This reduces waste and rework.
