Standards for Colour Assessment

Standards for Colour Assessment

Reliable colour assessment requires a controlled visual environment. SNKI supplies equipment and standards for objective, reproducible colour and appearance evaluation in accordance with international standards.

Light cabinets, colour assessment booths and digital systems such as DigiEye form the basis for consistent visual evaluation within production, quality control and R&D.

Purpose of colour assessment equipment

Colour assessment requires constant and standardized conditions. Equipment for visual evaluation enables:

• objective assessment of colour and appearance
• detection of variations between batches
• identification of metamerism
• decision-making in accordance with CIE and ISO standards
• replication of lighting conditions throughout the supply chain

These systems are essential for manufacturing companies that want to control colour quality.

DigiEye – Digital, non-contact assessment

DigiEye is an advanced system for digital colour and appearance analysis. The system offers:

• non-contact measurement
• analysis of surface, texture and pattern
• complete digital documentation
• reproducibility within global supply chains
• integration with DigiView and VisionView workflows

DigiEye enables consistent colour communication between suppliers, manufacturers and customers.
