Helios D: Print Defect Detection System

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

Digital printing technologies don’t eliminate the customer’s expectation that the printer will detect and remove a print defects. A print defect detection system is as essential for digital workflows as for any traditional analog process.  At AVT, we have re-imagined our sophisticated print defect detection for digital workflows. Not only does AVT’s Helios D reliably catch errors and defects in digital print; but Helios D pinpoints the root causes of those print defects, are points to the way to fixing them, quickly. These are the insights that you should expect from a systematic solution.


Uniquely Tailored to Support Digital Printing Needs


Easily installed on any digital press, the Helios D print defect detection system immediately identifies defects, such as missing nozzles, spots, substrate damages and color changes as soon as they occur. This real-time assessment 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.


Robust Inspection Algorithms


Designed exclusively for digital printing, the Helios D print defection inspection system is equipped with advanced algorithms to detect specific digital defects, including missing/deviating nozzles, non-uniform colors, and ink dripping on top of other common print defects, such as Die-cut register and Matrix removal problems.  


Seamlessly Connected 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, resulting in significant waste reduction.


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 the inkjet print heads.
