How inspection and quality assurance solutions impact on Industry 4.0 production lines

workflow, while providing insight into production behaviours. As a solutions provider who has always seen advanced metrics and quality control as key components for comprehensive inspection, this leaves AVT well- positioned for the Industry 4.0 revolution." Addressing the need for Industry 4.0

interconnectivity, automation and efficiencies that comprise Industry 4.0 production environments. More and more, printing and packaging lines are fully integrating Cloud-connected cohesive units that are perpetually tracking and analysing performance not only to control current product quality, but to ensure that the highest-possible quality continues through incremental improvements. Through digital tracking of key performance indicators (KPIs) and ‘big data’ metrics analysis all of this can be made possible. AVT’s recent acquisition by Danaher - which


provides increased possibilities for mutually beneficial working relationships with its collection of science and technology companies - will help AVT deliver solutions for a trend that it is already well-equipped to address. Jaron Lotan, president and CEO of AVT, says,

“Now that AVT is part of the Danaher family of companies, we have even more opportunities to work with strategic partners to collaborate on interconnected, linked solutions that automate

ccording to AVT, print inspection and quality assurance solutions increasingly need to support next-generation

solutions to be IoT-enabled, AVT’s new iCenter Platform is a next-generation Cloud-based solution that empowers printers to manage and control quality and production standards for facilities around the world, ensuring global consistency. Through iCenter, printers can set cross-site quality standards, auto-analyse PDF files for inspection and utilise business intelligence from the production floor with seamless connectivity to MIS and prepress solutions for optimised, automated workflows. In fact, a variety of AVT solutions are highly

suited to Industry 4.0 goals. For example, PrintFlow Manager collects data on relevant platform quality statistics, allowing oversight personnel to analyse and control production quality from desktops. Additionally, AVT’s ProMIS offers precise, mutual communication between print production MIS systems, preventing setup mistakes and increasing both accuracy and automation and its ZeroSet effectively eliminates operator intervention for digital printing. The company’s Offline Setup provides quality standardisation that reduces the human factor in the inspection process, resulting in reduced waste and streamlined setup workflows. With the burgeoning Industry 4.0 revolution promising to make production more cooperative

across sites, one industry mainstay that will become increasingly important is brand consistency. To that end, AVT offers SpectraLab II, a new generation of inline, automatic spectral measurement for nearly any application, including transparent flexible, paper and cartons. Offering compact design, advanced colour workflow management and improved inline-to-offline measurement correlation. SpectraLab II meets colour specialist X-Rite's lofty, ISO-compliant XRGA Standard for the graphic arts industry. It is based on the proven SpectraLab, with more than 30 packaging and label customers worldwide, and AVT’s Clarios, which is used on over 800 in-line colour systems throughout the world. AVT’s colour management prowess offers real-time spectral measurements like LAB, DeltaE and dot gain.

uniform in order to obtain optimum results. Only in this way will packaging films make the desired impression and adhesives perfectly fulfil their function. With the inspection of optical properties, the new inspection expansion now offers an efficient solution for reliably inspecting such quality aspects in plastic films. In the food sector in particular, packaging films

have to meet both highly practical as well as aesthetic requirements so as to appear attractive and keep goods fresh at the same time. A new dimension of inspection performance and precision is now expanding the focus of quality inspection from mere defect detection to include the inspection of optical material properties, thus encompassing all qualities that are important for the most demanding applications.

assurance, in which an inspector freely moves the film sample to generate various incidences of light and find defects. By using this method, defects and irregularities are quickly visible in and on the film. Due to a new kind of software, the inspection

systems capture the reflection properties and translucence of surfaces - and thus, also, the haze and gloss of the material along with the layer thickness and uniformity of a coating. Since the reflection and light absorption

behaviour of a surface can be interpreted in many ways, the reliable inspection of optical properties unlocks a large number of additional applications. In addition to the food and consumer goods

industry, pharmaceutical manufacturers in particular benefit from this advanced quality

control. While the design of tablet packaging has very little to do with aesthetic considerations, this kind of comprehensive quality control also, and most importantly, makes it much easier to implement high hygienic standards. Such a high level of quality control greatly simplifies the process for manufacturers to become qualified as suppliers for premium customers. The reliable inspection of plastic webs and their

optical properties enables users to inspect the entire range of potential quality restrictions with just one system, ensuring the very best results. Supplemented by numerous beyond inspection applications, optical inspection is thus more versatile than any other solution on the international market.
