Chamber-Anilox vs. Roller Coaters: Why the Choice Matters in Modern Print Finishing

When it comes to coating systems in print and packaging, not all technology is created equal. While roller coaters have served the industry well for decades, today's production demands call for something faster, cleaner, and more consistent. That’s where Chamber-Anilox metering systems shine.

Precision Fluid Delivery 

A roller coater applies coating by pressing fluid between two rollers, relying heavily on surface contact and operator adjustment. This often results in inconsistent coating laydowns, especially across varying substrates or job types. In contrast, a Chamber-Anilox system utilizes a doctor blade that meters coating onto a laser-engraved anilox roll. That roll then applies a highly controlled and consistent coating layer to the substrate. The result is smoother, more uniform coating with predictable and measurable thickness across the entire surface. 

Faster Setup, Easier Cleanup

Traditional roller systems typically involve manual adjustments, labor-intensive cleanup, and longer downtime between jobs. Harris & Bruno Chamber-Anilox systems are designed for speed. Quick-change anilox and applicator sleeves reduce setup time to minutes, and automated wash-up systems eliminate messy cleanouts.

Many of our customers see job setup completed in five minutes or less. Wash-up takes around ten minutes with no need to manually clean out tanks or rollers. This not only keeps jobs moving but also reduces labor costs and improves uptime.

Engineered for a Wider Range of Coatings

From aqueous to UV and primers, Chamber-Anilox systems support a broader range of coating types without extensive system modifications. The enclosed chamber design also protects the coating fluid from premature drying, which helps maintain consistent viscosity throughout the run. Whether you're flood coating or spot coating with embellishments, this system keeps quality high and adjustments minimal.

Additionally, the chamber-anilox system handles particulates such as soft touch and matte with ease. In contrast to the roller-coater system, the anilox roll is able to deliver a metered amount of coating and particulate mix to every portion of the sheet. Over time, a roller coater system will struggle to maintain this balance. Specifically with roller coaters, particulates will collect at the nip and never make it to the sheet. This creates the need for constant operator intervention, driving up the cost of production.

A Cleaner, Safer Work Environment

Open roller coaters can create overspray, splatter, and fluid loss. Enclosed Chamber-Anilox systems contain the coating within an enclosed unit, reducing environmental mess and keeping the work area safer. By controlling exposure to air and contaminants, the system also extends the life of coatings and reduces operator contact with chemicals.

Built to Scale with Your Business

As production needs grow, the modular design of Harris & Bruno’s Chamber-Anilox systems allows for easy upgrades. Whether you start with an AQ-only unit or need something that can handle multiple chemistries, the ZR platform can be customized or expanded to meet your needs without a complete equipment overhaul.

Chamber-Anilox coating technology isn’t just a better way to coat, but rather the most cost-effective and operationally efficient way to coat for modern printers, regardless of offset, digital, or both sheetfed and web inkjet.
