Features

The color2view combines intuitive navigation, breakthrough technical performance, and multiple measurement methods - 45°c:0° color, 20°/60° gloss, and fluorescence - in one benchtop spectrophotometer.

  • Objective 45°c:0° color measurement –  to measure color as you see it
  • 20° and 60° gloss measurement to clearly differentiate medium to high gloss samples
  • Quantification of fluorescence to predict long term color stability 
  • Compact and lightweight design with sample opening "top and front" to best suit different sample sizes 
  • Large color touch display with icon-based menu for ease-of-use
  • Live preview of the measurement spot to avoid false readings 
  • Smart high tech LEDs with peak performance for digital standards

Connaissance

Les éléments de base de la mesure de couleur

La perception visuelle des couleurs est influencée par nos préférences de couleur individuelles, qui dépendent de facteurs personnels (humeur, âge, sexe, etc.), de l'environnement (éclairage, environnement, etc.) ainsi que de notre capacité à communiquer les couleurs et les différences de couleur. Une couleur semble différente dans les grands magasins (éclairage fluorescent blanc froid) et à la maison (éclairage chaud et incandescent). Afin de garantir une couleur et une apparence cohérentes dans toutes les circonstances possibles, il est essentiel de normaliser la source lumineuse et l'observateur mais aussi de comprendre les données de réémission spectrale de l'objet. Ces informations serviront de base au calcul des données colorimétriques car elles seront utilisées pour la communication des couleurs et le contrôle qualité des couleurs en production.

Color Difference Equations for Solid Colors

It is now almost 100 years since, in 1931, the CIE Yxy chromaticity color space was defined by the “International Commission on Illumination (CIE)”. To overcome its limitations of not being uniform, the CIE recommended two alternate color spaces since then: CIELAB (or CIE 1976 L*a*b*) and CIELUV (or CIE L*u*v*). They are based on the opponent color theory of color vision, which says that two colors cannot be both green and red at the same time, nor blue and yellow at the same time. During the last years developments of new color difference equations and color spaces were carried out. Their goal was to improve the correlation between visual perception and instrumentally measured values. Additionally, they wanted to permit the use of a single number tolerance for all colors.

Color Measurement of Fluorescent Colors – a CHALLENGE

The world around us is bright and colorful. Neon colors in particular have been back in trend for several years. The prerequisite for this is the use of fluorescent pigments in the paint, plastic and many other industries. Although these have been widely used for many years, the quality control of fluorescent material still remains a major challenge. The following article describes theoretical background of fluorescence, why a standard spectrophotometer is not suitable for the quality control of fluorescent material and what possibilities the new combination of spectrophotometer and fluorimeter offers - especially with regard to predicting the lightfastness of a material.
