Labelexpo Europe review: Workflow and inspection show automation gains

Automation has impacted how hardware is integrated into the factory environment and workflow onto the press and between label converter, customer and suppliers. Whereas before it was necessary for an operator to perform many manual operations – for example checking printing pressure and registration – these can now be handled automatically by feedback systems on the press. Color is being managed more in pre-press, so by time job gets on the press operators are not chasing color. And with 7-color ECG systems, matching spot colors can also be fully automated and checked in-line on the press. 
AVT, co-located with its partner Esko, showed its newest automated inspection equipment supported by next-generation workflow automation

Artificial intelligence – or machine learning – is starting to make an impact, particularly with inspection systems. We are moving from detecting defects to preventing defects. Camera systems are learning what a print error is and how it is caused, and will increasingly make suggestions back to the operator, and eventually in a closed loop back to the press controls. We’re already seeing intelligent predictive maintenance systems looking what might be wearing out before a problem becomes evident. These systems are going to get smarter, and will likely become standard on all levels of machinery. 

AI-driven factory automation is another key trend, using intelligent systems to help run a plant. Today’s label converting plant has increasingly complex workflows – conventional presses, digital presses and various kinds of hybrid, and printing many types of labels and now packaging as well. This impacts on stock holding and so on right down the line to the supplier. 

The fully automated factory is where we are headed. Not working autonomously, but working as a cyber assistant to human skills and judgment. 

AVT, co-located with its partner Esko, showed its newest automated inspection equipment supported by next-generation workflow automation for Industry 4.0 ‘smart factory’ production. AVT’s products enable converters to set cross-plant quality standards in tandem with Esko’s Automation Engine (AE) and X-Rite’s ColorCert. 

AVT’s AutoSet module automates job set-up by streamlining pre-press to pressroom connectivity from the Esko Automation Engine to AVT’s inspection system. Meanwhile, the iCenter platform empowers converters to tightly control cross-site quality standards, ensuring global consistency. 

For color measurement, the digital link between X-Rite’s ColorCert color and AVT’s Spectralab in-line color measurement device automatically sets up a job for in-line color measurement and generates color scorecard reporting on color quality performance after printing. This integration delivers better visibility into color performance based on measurable, objective results for increased color consistency. 

For 100 percent inspection, AVT’s Helios Turbo HD+ was on show. It provides high-resolution automatic inspection designed for exacting quality assurance of fine details, barcodes and variable data, and for customers operating wider-web platforms (445-670mm).

Press managers can monitor changes as they happen, and make informed decisions about print quality, defect management, and even operator-to-operator performance. Guardian OLP Offline Proofing & Inspection focuses on pre-press proofing and pressroom quality control. Graphic-Vision 500 Series Web Viewing Systems quickly find defects such as mis-registrations, streaks, voids and fills. 

For color management, BVS offered ColorTrack software, which facilitates fast, accurate press-side correction of ink formulations. ColorTrack integrates with ink recipe software to simplify workflow, and reduces the number of ink corrections needed to achieve accurate, optimal color. 

BVS introduced its new ColorTrack Analytics software, which is designed to help printers deliver consistent, accurate color quality and customer reports.

Brain4Tools was showing some interesting software to manage the print tool inventory – including determining ideal print sequence for faster job preparation. The company also demonstrated the Scan4Tools application which captures information during tool check-in and check-out, including archive number and job run length. 

BST eltromat and technology partner Hybrid Software demonstrated software integration which closes the gap between e-commerce portals, pre-press workflows, MIS/ERP systems and printing presses. 

In the web monitoring and 100 percent inspection area, BST’s product line ranges from the TubeScan family of 100 percent inspection systems of partner Nyquist Systems, and the PowerScope 5000 video web monitoring system to the iPQ-View and iPQ-Check high-end systems.

The company also presented new systems for wide web inspection up to 1,700mm (67in) and the EyeC Proofiler 1200 DT with scan size up to 1,270 x 915mm (50 x 36in).

To streamline inspection processes, EyeC and Hybrid Software have launched the EyeC Driver, a new application that integrates EyeC’s PDF proofing technology – the EyeC Proofiler Graphic – into Hybrid Software’s Cloudflow. The integration triggers inspection procedures within Cloudflow automatically, retrieving job data, files and inspection parameters from the workflow system. Pre-press files are inspected and released automatically if they match the approved artwork. Pre-press operators only have to intervene when deviations are detected. A task appears in their workspace that opens the EyeC Proofiler Graphic for an easy review of discrepancies. 

Global Graphics Software, whose Harlequin RIP powered all HP Indigo’s presses at the show, previewed Version 2.0 of Fundamentals. Fundamentals is a cooperation between Global Graphics Software and Hybrid Software, who have worked together to ensure that the essential software components needed to create a DFE are accessible from a modern web-based user interface designed to remove complexity from the print process. Providing a native PDF workflow, Fundamentals is branded and customized to the requirements of a specific press or application. 

Fundamentals job management is based on Hybrid Software’s Cloudflow workflow. In version 2.0 multiple users can submit jobs to the job queue. Jobs are easy to spot in the queue, indicators show their status, and operators can easily prioritize rush jobs or reorder them. Easily brandable, it is possible for a manufacturer to develop the same look and feel for a DFE to support all their printer models. Visitors could also see a demonstration of the Mark Andy version of a DFE created using Fundamentals in ProWorx on Mark Andy’s booths. 

GMG Color introduced a direct connection between its ColorServer and OpenColor packages which enables users to publish profiles created in GMG OpenColor directly into GMG ColorServer.

GMG will also demonstrate how complex packaging designs and layouts including spot colors can be simulated with color-accurate proofs on media close to packaging production substrates, including transparent or metallic film using the Epson SC-S80600. GMG also introduced GMG ColorCards, which allows users to create digital color references in less than three minutes. Based on spectral color values, the digital color cards can be printed in various layouts and with accurate substrate simulation.

Hybrid Software held demonstrations for more than 500 companies during the show, and reported 27 sales of its VDP (variable data printing) software. VDP is available as an option for Hybrid’s native PDF editors Packz and Stepz, with accelerated processing available through its Cloudflow workflow.

Hybrid Software’s VDP implementation changes text, images, barcodes, colors and other elements linked to variable data sources, producing an optimized file for fast printing on all digital presses. It can be used to turn any PDF package or label design into a VDP design by simply indicating which elements are dynamic and linking them to the data source – without having to create a template for the label designer, first. Hybrid VDP is applied at the prepress stage, not in the pressroom, eliminating the up-front template creation that can slow down other VDP systems.

Label Traxx announced new software features including integration with HP Indigo, Esko and Herma systems. Label Traxx promoted workflow software dedicated to flexible packaging which helps with the accurate and consistent estimating of unsupported film, sachets and pouches by weight. 

The company also demonstrated Siteline, its online interface, enabling end users to order repeat labels, view product specifications and see order history. Now, they can also approve projects from mobile devices.
