Challenges in Print Inspection – Our Expertise

 

Printing processes – whether analog or digital – demand flawless quality at industrial speeds. Continuous inspection is essential to detect defects early, avoid waste, and ensure consistent results. Each technology comes with unique challenges:

Analog Printing

High Speed and Continuous Control

  • Very high printing speeds of up to 15 m/s at a resolution of 100–300 dpi
  • Demands continuous inspection for color consistency and defect detection (streaks, spots, misalignments, smudges etc.)
  • Requires optimized line-scan cameras and lighting to achieve 100% inspection at high speed and accuracy

Digital Printing 

High Resolution, Maximum Precision

  • Ultra-high resolution up to 2400 dpi for speeds of approximately 3 m/s
  • Sensitive to nozzle failures (~20 µm) and print head alignment issues
  • Needs high-resolution line-scan cameras with uniform lighting for precise calibration and reliable defect detection

 

Proven Technology for Print Inspection

Our print inspection systems combine advanced hardware and software for reliable defect detection and precise colour control – ready for seamless integration into your printing systems.

  • State-of-the-art trilinear CMOS line scan sensors with a resolution of 4k-16k
  • Full RGB in every pixel
  • Optimised hardware and firmware, developed through over 20 years of experience in print inspection
  • One system for both: 100 per cent print inspection and inline colour measurement
  • Cost-efficient, less cabling and minimal
    space requirements

  • Inline colour measurement with Lab-calibrated cameras based on Chromasens colour calibration software
  • RGB → L*a*b* conversion ensures precise colour values
  • Automated calibration workflow with in-house software and over 1,000 colour fields – as reliable as spectrophotometer measurements, but in real time
  • Colour measurement across the entire print area, not just in the control strip – a major advantage, especially in web printing, where sheet extraction is not possible

  • High-intensity, uniform white light for every material
  • Reliable on reflective coatings, transparent films and different material thicknesses
  • Developed for high-speed inspections without loss of accuracy
  • Special solutions for film printing and demanding materials

  • Integrated line scan camera, illumination, mirror and thermal management
  • Mechanically and electrically pre-assembled, fully tested
  • Compact, robust, cost-effective design with long service life
  • Plug & play: safe and easy integration into your printing systems
