Benefits of Lehani Standard Lighting Systems

Lehani lighting systems provide standard-compliant, reproducible lighting conditions for colour-critical inspections and support reliable colour decisions throughout the entire workflow.

Colour charts and inspection loupe for accurate colour assessment

High Colour Rendering (CRI)

Accurate colour assessment as the basis for reliable quality control and approval decisions.

Inspection of a printed sheet under a standard light

Uniform Illumination

Even, flicker-free light without distracting shadows throughout the entire inspection area.

Colour matching on a red vehicle surface

D50/D65 Standard Lighting

Defined colour temperatures for printing, laboratory and industrial quality control.

Reduce Costly Errors

Colour deviations become visible during production. This helps avoid reprints, complaints and unnecessary loss of time and material.

Reliable Approvals

All stakeholders assess colours under identical lighting conditions. This creates a reliable basis for approvals and reduces misunderstandings in the coordination process.

Long-Term Investment

Modern standard lighting systems are energy-efficient, low-maintenance and reliable. They provide constant inspection conditions and high colour accuracy over many years.

Applications

Lehani standard lighting systems are used wherever colours need to be assessed reliably and reproducibly:

  • Printing companies & prepress
  • Agencies, graphic design & media design
  • Packaging printing & industry
  • Retailers of products with colour-critical requirements
  • Photographers & content producers
  • Quality management in production and logistics

Lehani Standard Lighting in Production

Lehani lighting systems can be seamlessly integrated into existing production environments. This enables colour-critical inspections directly on the production line – without media discontinuity or additional routes.

Why Standard Lighting Matters

Colours appear differently depending on the light source. Standard lighting simulates defined lighting conditions and ensures that colours can be assessed consistently everywhere – objectively, reproducibly and reliably.
