Latest inspection advances address increasing pressure on labels and packaging converters to deliver consistent and defect-free print
A
s labels and packaging converters face increasing pressure to deliver consistent, defect-free print at higher speeds and tighter margins, the role of inline inspection technologies has become more critical than ever. The drive for effi ciency, sustainability and brand protection is accelerating the adoption of more advanced, integrated inspection systems across the industry.
“Today’s production environments are more complex, with shorter runs, greater SKU variation and stricter quality expectations from brand owners,” said Guy Yogev, VP of marketing & product, AVT (Advanced Vision Technology). “These factors are placing new demands on converters, who must balance productivity with precision while reducing waste and maintaining compliance with industry standards.”
FROM QUALITY CONTROL TO PROCESS OPTIMISATION
“Inline inspection is no longer limited to detecting defects, but is increasingly being used as a tool for overall process optimisation,” said Guy. “Modern 100 per cent inspection systems provide real-time visibility into print performance, enabling operators to identify issues early, reduce setup times and maintain consistent output across entire runs. “By integrating directly into presses, rewinders
and fi nishing equipment, these systems support continuous monitoring without interrupting production. This shift toward embedded quality control helps converters move from reactive problem-solving to proactive process management.”
Solutions such as those developed by AVT illustrate this evolution, with systems capable of identifying a wide range of defects in labels, narrow web and packaging printing from misregistration and colour variation to more subtle inconsistencies, while maintaining performance at production speeds. “Automation is playing a key role in addressing labour challenges and reducing reliance on operator intervention,” he said.
“Recent developments in artifi cial intelligence and data-driven workfl ows are enabling inspection systems to learn from production data, improving accuracy and decision-making over time. AI-driven tools are increasingly being applied to areas such as defect classifi cation, workfl ow optimisation, and data handling. By reducing manual intervention in processes like roll editing and inspection review, these technologies help streamline operations and improve consistency.”
As data becomes central to production environments, the ability to capture, analyse and act on real-time information is becoming a defi ning factor in operational performance. “Advances in inspection technology are also broadening the range of detectable defects,” said Guy. “In addition to traditional print issues such as streaks, ink splashes and misprints, our latest innovations mean that systems are now capable of identifying more complex or previously undetectable defects, including those related to coatings, varnishes and special materials.”
This is particularly relevant as converters increasingly incorporate value-added embellishments into labels and packaging. Inline inspection of these features reduces reliance on manual checks, which can interrupt production and introduce variability.
COLOR CONSISTENCY AND SUSTAINABILITY KEY IN GLOBAL MARKET Maintaining accurate and consistent colour remains a key challenge, especially for global brands that require uniformity across multiple production sites. Traditional handheld measurement methods, while still widely used, are limited in scope and can be time-consuming.
“Inline spectral colour measurement is a more effi cient alternative, enabling continuous monitoring during both make-ready and production,” said Guy. “By detecting colour deviations in real time, converters can make immediate adjustments, reducing waste and improving repeatability across runs and locations.” With an increasing focus on sustainability, reducing waste is also a key priority for converters. Inline inspection contributes directly to this goal by identifying defects early, minimising material loss, and reducing the need for rework. “At the same time, faster setup times and improved process control help maximise press uptime and overall equipment eff ectiveness, critical factors in a market where margins remain under pressure,” said Guy. One of the defi ning trends in inspection technology is the move toward fully integrated solutions. Rather than relying on multiple standalone systems, converters are increasingly adopting platforms that combine inspection, colour measurement, data management and workfl ow automation.
“This integrated approach simplifi es operations, improves visibility and enables better coordination across diff erent stages of production, supporting the broader shift toward connected and intelligent manufacturing environments,” said Guy.
“As the demands on labels and packaging converters continue to grow, inline inspection technologies will play an increasingly strategic role,” said Guy. “Future developments are likely to focus on deeper integration, enhanced AI capabilities and greater use of data to drive continuous improvement.
“At the same time, investment in regional infrastructure, technical support and customer engagement will remain important in ensuring that these technologies deliver their full value in practice,” he said. “For today’s labels and packaging converters, the evolution of inline inspection is not only about quality assurance, but is also about enabling a more effi cient, responsive and resilient production environment in an increasingly competitive market.”
