Innovative Vision System For Print Inspection And Color Measurement
More Sustainability, Fewer Misprints
The printing industry faces the challenge of delivering the highest print quality while reducing waste and optimizing production processes to achieve greater sustainability. To meet these requirements, CCL Label, a printing expert specializing in printing on shrink sleeves, has developed an innovative inspection system in collaboration with Virona GmbH and Allied Vision that detects errors at an early stage and ensures consistently high quality. By using four allPIXA evo 8k color line scan cameras from Allied Vision, both color measurement and print inspection are performed inline.

Balancing Print Quality, Waste Reduction, And Inline Color Control
CCL Label produces high-quality shrink sleeve labels on ultra-thin transparent films with complex designs and critical product information. The challenge was to ensure consistent print quality, reduce waste, and enable precise inline color measurement - despite the fact that conventional color control elements cannot be used on sleeves.
The Solution
Inline Print Inspection And True-Color Measurement In One Integrated System
CCL Label collaborated closely with Virona and Allied Vision to develop a customized inline inspection solution for shrink sleeve printing:
-
Early detection of printing defects and real-time inline color measurement across the full web width
-
Use of high-speed allPIXA evo 8k color line scan cameras for maximum resolution and accuracy
-
Reliable color measurement based on patented illumination and calibration technology
-
Automated evaluation enables immediate process optimization and stable print quality
-
Up to 50% waste reduction, faster job setup, and significantly improved production efficiency
The Benefits
- Precise color control: Inline color measurement across the entire print width without color patches – with color deviation < ΔE°° 1,3
- Significant cost reduction: Up to 50 percent less waste thanks to early error detection
- Increased efficiency: Shorter setup times, fewer operating hours, lower energy consumption
- Sustainability: Reduced material usage and resource protection
- High flexibility: Suitable for complex printing processes and transparent film material
The Camera: allPIXA evo 8k
