Helios automatically detects defects such as missing labels, defects in character areas, color variations, miss-registration, missing print, spots, imperfect matrix peeling, die cut registration, and more. To achieve superior inline quality assurance and process control, Helios is quickly and easily installed on any press or rewinder, including a slitter rewinder. Helios can also be installed on other types of finishing equipment, as it supports current and future converting equipment, regardless of machine speed, width or technology.
When installed on a printing press, Helios operates as an inline quality assurance and process control solution, alerting on potential print problems and recording every relevant defect. Via an integrated reporting mechanism from press to rewinder, the WorkFlow Link module (optional) is later used for downstream repair on the finishing machine or in quality reports for the end-user. Helios is also equipped with a built-in PrintFlow module, where operators use inline reporting to review job/order/roll reports, edit and export to digital files, or print reports for later material handling.
When installed on a rewinder, Helios seamlessly controls the rewinder, creating a combined automatic inspection station. The system automatically inspects 100% of the labels or packages and stops the rewinder at defect locations to clean the defective parts before the roll is sent to the end-customer.
All predefined Helios Product Line bundles include a rich and varied selection of optional add-on modules built to enhance and support your print inspection process, guaranteeing 100% quality inspection on every print job.
Job Verification Tools
To prevent costly production errors, job verification is performed early in the process, during the set-up stage. AVT’s verification toolset includes a robust PDF comparison module that compares every new job to the original PDF digital file or to the previously saved master image in case of re-runs.
Color Measurement & Monitoring Techniques
An integral part of the print inspection process, inline color monitoring and measurement offers a variety of modules to support the workflow. Inline Delta E color monitoring enables a simple, standard method of alerting on color deviation during print run. In parallel, an inline spectrophotometer delivers real inline, ISO standard, dual-beam spectral color measurements on existing color targets or in image areas for absolute, accurate L*a*b*, density, and dot gain measurement with enhanced reporting and a complete color workflow.
Barcode & Variable Data Verification
AVTs’ barcode and variable data verification enables label printers to inspect and verify 100% of the printed 1D and 2D codes as well as human readable items. It detects and alerts on any duplications, missing codes, barcode quality and readability, or any other code validity concerns. The system can compare and validate printed codes against the original database, and export complete reports per roll or job.
Possibly the most important component of any print job is its workflow – the key to streamlining and standardizing the steps required to carry out a task. AVT Helios‘ range of workflow modules help speed up overall print production via seamless transfer of quality data from the press to the rewinder to efficiently remove defective material. AVT Workflow Link automatically stops the rewinder at the relevant defect location, saving valuable time and resources, and automating the quality assurance process.
Data Collection & Automatic Storage
In order to efficiently collect, analyze and edit the quality PrintFlow data collected by the Helios inspection platforms, a data management tool (PrintFlow Manager) provides key users with remote data access directly from their desktop. PrintFlow Central is a central automatic storage of job data and roll reports, and supports central backup of all data, enabling continuous availability of inspection data at all times for analysis, management, and complete workflow downstream.
Setup & Automation Tools
The success of any print production process rests on process automation. To ensure quick and secure system setup, save valuable production time, and ensure consistent quality standards, several AVT Helios modules were designed. Modules include communication with existing MIS (ERP) systems in the production facility and remote system setup using offline setup utilities to prepare jobs in advance, through connectivity with Esko’s automation engine and pre-press to enable fully-automated setup and inspection for both conventional and digital presses.
