What Is an Anilox Cell? A Complete Guide for Flexo Printing Beginners

In the world of flexographic printing, achieving consistent ink transfer and high-quality results depends heavily on one critical component: the anilox roller. But what makes the anilox roller so essential lies within its microscopic structure—the anilox cell.

In this guide, we’ll explain what an anilox cell is, how it works, and why it’s vital for anyone using anilox rollers for flexo printing. Whether you're new to flexo or looking to upgrade your equipment, this article will provide a solid foundation.

 What Is an Anilox Cell?

An anilox cell is a tiny, precisely engraved indentation on the surface of an anilox roller or sleeve anilox roll. These cells are responsible for carrying and delivering a controlled volume of ink or coating to the printing plate during the flexographic printing process.

Typically made from ceramic anilox rollers, the roller’s surface is laser-engraved with thousands or even millions of microscopic cells. Each cell holds a measured amount of ink, ensuring consistent ink transfer with every rotation.

 Key Specifications of Anilox Cells

Understanding the characteristics of anilox cells helps in choosing the right roller for your job:

• Cell Volume (cm³/m²): Refers to the amount of ink the cell can hold. Higher volumes are used for solids; lower volumes for fine detail.

• Line Count (LPI): The number of cells per inch. A higher line count means finer cells and smoother prints.

• Cell Angle: Common angles include 30°, 45°, and 60°. The 60° hexagonal angle is the industry standard for most flexo printing anilox applications due to its uniform ink distribution.

 How Anilox Cells Affect Print Quality

The size, shape, and depth of the anilox cells directly affect:

• Ink Density: Proper cell volume ensures optimal ink transfer.

• Print Clarity: Fine cells prevent dot gain in high-resolution prints.

• Coating Consistency: For applications like coating anilox, uniform cells ensure even surface coverage.

 Types of Anilox Rollers and Sleeves

At JCTPRINT, we manufacture a full range of anilox products to meet various printing needs:

 Ceramic Anilox Roller

Highly durable and resistant to wear, these are ideal for long production runs and aggressive cleaning.

Sleeve Anilox Roll

Lightweight and easy to handle, anilox sleeves are commonly used in gearless and CI flexo presses. They offer quick job changeovers and reduced downtime.

 Custom Anilox Printing Rollers

Tailored to specific printing widths, line screens, and volumes—perfect for narrow-web, wide-web, and corrugated applications.

 Cleaning and Maintenance Tips

To maintain the integrity of the anilox cells:

• Use ultrasonic or laser cleaning for deep cleaning.

• Avoid metal brushes that can damage ceramic surfaces.

• Regularly inspect cell volume with a microscope or cell volume reader.

Clean anilox cells are critical for maintaining consistent ink transfer and reducing waste during flexo printing.
