FROM REACTIVE TO REGULATED: HOW ANILOX INSPECTION IS EVOLVING TO MEET PPWR AND EPR

For most flexographic operations, anilox roll management has always been fairly reactive. Measurement is taken when something goes wrong, replaced when performance drops and in between operators trust that print quality is holding up. For a long time that was good enough.

That is changing. Two regulatory frameworks, the EU’s Packaging and Packaging Waste Regulation (PPWR) and the UK’s Extended Producer Responsibility (EPR) for packaging, are raising the bar on what converters need to demonstrate around material efficiency and waste reduction. Both are now in effect and both carry real financial consequences.

The EU’s PPWR – published as Regulation (EU) 2025/40 – will apply directly across all member states from 12 August 2026. Unlike the old Packaging Directive, which let each country implement rules differently, PPWR is a regulation. It is a uniform set of obligations for everyone placing packaging on the EU market. All packaging must be designed for recyclability and material use must be minimised, whilst waste must be demonstrably reduced.

In the UK, EPR for packaging moved into practice in April 2025. Producers received their first invoices in October, transferring approximately £1.5 billion (€1.74 billion) annually from local authorities to the businesses creating the packaging. From 2026, fees are modulated based on recyclability ratings. Packaging rated poorly costs more. Packaging that performs well costs less.

Both frameworks come down to the same thing. Every gram of excess ink, every metre of wasted substrate, every avoidable reprint now carries a regulatory cost on top of the internal one.

Anilox roll condition is one of the biggest variables affecting ink film thickness on a flexographic press. A roll that has lost 15–20% of its cell volume through wear will usually prompt operators to compensate. They increase ink density, adjust press speed or switch to a stronger formulation. The print looks fine but the operation is quietly using more material than necessary.

The difficulty is that this degradation is invisible without proper measurement. It is not possible to see gradual volume loss by eye. Many operations unknowingly run with compromised tooling, absorbing those inefficiencies across every job. Regular, data-driven anilox inspection catches degradation early, before it reaches the press.

One of the longstanding challenges with anilox inspection is that the measurement process itself can feel like an interruption. 
If scanning is slow, if results take time to transfer or if the device needs charging partway through a shift, people delay it. Inspection only happens during scheduled audits and problems get found after the fact rather than before.

This is the practical problem the Troika EVO is designed to address. As the evolution of the AniCAM HD™ Plus, the focus has been on removing the barriers that stop people measuring more often. 
The 2.3 megapixel sensor – double the resolution of the previous generation – picks up finer wear and cell deformation that would previously have gone unnoticed. Scanning and processing speeds mean results are available almost immediately. USB 3.0 and USB-C connectivity keeps data moving without delays. In addition, an improved battery management system means the device lasts a full shift without needing to recharge.

The practical difference is that operators can check a roll before every job changeover, not just when someone suspects a problem. Over time, that shift from periodic to routine inspection builds the kind of consistent, traceable quality data that PPWR and EPR compliance actually requires.

Accurate measurement on its own is not enough. Under both PPWR and EPR, converters need to show that process control is systematic. Not just that a measurement was taken, but that it informed a decision and that this is happening consistently across sites and over time.

The Troika Management System (TMS) is a centralised, unlimited database that logs every anilox roll and gravure cylinder across all of an operation’s sites. Every asset gets a unique ID and a full history, including volume measurements over time, wear trends, cleaning records, service notes and job usage, tracked in revolutions and print distance. Scan data from Troika EVO feeds in automatically so the record builds without manual entry.

For multi-site operations this visibility is particularly valuable. Roll condition can be compared across plants, spot which sites are replacing assets more frequently and see whether the same roll performs differently depending on where it is being used. Operators can filter inventory by volume, screen count, cell type and condition to find the right roll for a job based on verified data rather than guesswork. That means faster make-ready, less ink adjustment and fewer wasted sheets getting up to colour.

From a compliance standpoint, 
TMS makes the audit conversation straightforward. When a customer or regulator asks how to manage material efficiency on the press-room floor, there is a documented, time-stamped answer. Rolls are inspected, worn assets are identified and dealt with, and ink volumes are matched to specifications rather than estimated.

The regulatory landscape has moved on from encouraging good practice to requiring proof. For converters who already take process control seriously, that is not just an obligation but an opportunity to differentiate. Brand owners are under their own pressure to demonstrate sustainable supply chains. A converter who can back up efficiency claims with auditable data becomes a stronger partner. The converters who treat this shift as a reason to invest in better measurement and better data will be best positioned for what comes next.
