Seamless and efficient removal of defective material – save up to 30% on time and waste removal!
AVT’s WorkFlow Link (WFL), serves as your trusted and reliable connection between printing and finishing, for the efficient removal of defective material in the print production process. WFL helps speed up overall print production via seamless transfer of quality data from press to rewinder, in order to efficiently remove defective material.
Using data generated by AVT’s on-press inspection system, WFL automatically stops the rewinder at the relevant defect location for fast and efficient waste removal, to ensure shipment of defect-free material. Generating quality reports with detailed defect images helps operators identify problem areas, assists in the decision-making process to enhance production and delivers quality print jobs.
AVT inspection platforms supported by WFL include Helios, Apollo, and Argus.
WorkFlow Link is integrated into the print production process and is comprised of three main modules, each of which supports the various printing process stages. To enable efficient information flow throughout the entire process, all WFL components are seamlessly connected via a local network.
1. Inspection – WFL Press Side Module
Generally installed on a printing press, laminator, or digital finishing machine, the Inspection module stores information and images of the detected defects and their location within the printed roll. For each printed roll, a digital roll report is stored in the database. WFL Press Side module synchronizes defects detected and stored by the inspection system with their accurate location on the printed web.
2. Editing – PrintFlow Manager (optional)
The Editing station enables smart decision making of the digital roll report determining which of the detected defects should be removed and at which stage, in accordance with your QA standards. The Editing station ensures that the rewinder stops only for relevant defects, allowing the rewinder to run at faster speeds.
Editing can be performed on pressor on the rewinder.
3. Defect Removal – WFL Rewinder Side Module
Generally installed on a rewinder, the WFL Rewinder Side Module uses the information in the digitally edited roll report to automatically stop the rewinder only on the relevant defects, enabling the operator to replace defective labels or remove defective material, ensuring your customers’ receive defect-free material.
Roll Identification and Synchronization
WorkFlow Link supports various production workflows, whereby a suitable workflow is customized for your production workflow, based on the configuration of the printing press and your requirements. In most workflows, WFL uses a ‘Single Barcode’ for roll identification and synchronization, where the barcode is applied on the press, at the end of each printed roll, either manually or automatically. Barcodes are read into the WFL Press Side Module and assigned to the relevant digital roll report using a manual or automatic barcode scanner.
To provide accurate defect location information, additional sensors are installed on the press and the rewinder. Depending on the print application, a variety of sensors, such as optic, UV optic and label sensors, may be deployed.
