Dedicated 100% Automatic Inspection Solution for Labels & Narrow Web Digital Printing

Based on AVT’s trusted, market-proven Helios product line, AVT Helios D is a superior automatic 100% print inspection solution designed to meet the unique needs of labels and narrow web digital print jobs. Helios D supports every stage in the digital production workflow, starting with missing nozzle detection in the printing stage, to comprehensive print quality and process control.

Helios D automatically inspects printed labels or packages for defects and imperfections, delivering exceptional quality results and eliminating customer rejections, raising the bar on automatic print inspection.


Easily installed on any digital press, Helios D immediately identifies defects, such as missing nozzles, spots, substrate damages and color changes as soon as they occur. The process effectively reduces waste, enhances production performance and over time, provides comprehensive inkjet print head status monitoring.

Further, Helios D is designed to work seamlessly on any application and substrate – from food and beverages to pharmaceuticals, label stock to transparent film, or on any highly-reflective foil.

How it works

Helios D allows operators to take corrective measures at the very start of a defect, before waste becomes widespread, including a preventive maintenance scheduler tool which continuously tracks the inkjet print heads.

Helios D is equipped with advanced algorithms to detect specific digital defects, including streaks, non-uniform colors and ink dripping on top of other common print defects, such as Die-cut register and Matrix removal. Once a defect has been detected, a pop-up screen appears, while traffic lights indicate the severity of the defect, enabling operators to take immediate action. The system also detects other label-related defects, such as missing labels, text defects, color variations, mis-registrations, mis-prints, spots and splashes, die-cut registration and more.

Calibration Targets

An advanced setup and press maintenance solution, Helios D is designed to reduce setup time, minimize waste and manage press-related problems prior to running a job. Proprietary AVT calibration targets are printed, giving operators real-time analysis of all quality parameters in a single file, saving significant time in comparing each parameter separately.

Printing Press

When installed on a printing press, Helios D 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 D 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.


  • True Digital Power

    Supports shorts runs and print on demand, the key benefits of digital printing. By inspecting each individual label, tracking barcodes and detecting digital defects, Helios D allows customers to enjoy the real benefits of digital printing.

  • Seamlessly Connects to Your Workflow

    With fast and easy automated setup time of one minute or less, clear and concise pop-up messages and smart alerts, Helios D allows operators to take immediate action once a defect starts, minimizing waste and managing press-related problems prior to running a job.

  • Built-in Archiving and Reporting

    Equipped with a built-in PrintFlow module, Helios D efficiently handles all data archiving and reporting, including detailed information about the status of inkjet print heads.

  • Any Application – Any Substrate

    Supports all label stock, paper and plastic label stock, flexible, transparent & opaque films, paper & cartons, and thick embossed metalized foils, as well as highly reflective holographic foils and laminates.

  • Reduces Waste

    Significantly reduces waste and production costs, decreases re-prints, and boosts overall productivity and efficiency.

Optional Modules

The Helios D includes 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.
