SpectrophotomètresIndex. décimale : 535.6 Couleur Résumé : In many industries, defined colors are not only an important feature of the product, but also a growing challenge. Increasing demands on the appearance quality must be implemented more and more frequently and efficiently across global production networks. There, physical standards may enhance quality, but the digital processing and communication of color data is more efficient. Note de contenu : - Digital communication of standards
- The path to digital color communication
- Profiling the spectrophotometers
- Improved agreement between instruments from different manufacturers
- Fig. 1. On the left, the typical behavior of measuring instruments made by different manufacturers as well as by the same one is displayed. In each case, the absolute values from different spec-trophotometers form a characteristic cluster. On the right, the data subsequent to profiling is shown.
- Fig. 2. A common color tolerance for products for car interiors (outside, dE00 = 0.50) as well as the IMA (Inside) required for digital communication of standards. If mean and maximum deviations towards the reference instrument are kept, the system error corresponds to the system error when physical standards are used - minus the disavantages.
- Fig. 3. The absolute agreement dE00 between color differences of RAL samples (PP) prior and subsequent to profiling. The required value of dE00 = 0.10 was achieved by the Ci7860 subsequent to profiling.
- Fig. 4. User interface of CAPQ software. All relevant information is included.
- Table 1. The results show an improvement of the IMA, meeting the required values. In particular, the maximum deviations were clearly reduced. Thus, the data situation allows digital communication. However, the samples must be described as ideal, i.e., opaque without differences in structure or gloss.En ligne : https://drive.google.com/file/d/1_z-HpOiQrt7y6YXWUMSg8onfWzu9QnRg/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=30986

vision des couleursIndex. décimale : 667.9 Revêtements et enduits Résumé : The Mission : The latest knowledge on the colour technology underpinning coatings in a single book – from the fundamentals of colour perception, to colour measurement and colour-order systems, through to the characterisation and practical application of pigments. The book serves as a vehicle for acquiring a solid grounding in the key principles underpinning the application of colour technology to coatings. Indispensable for coatings experts and those with aspirations in that direction.
The Audience : Trainees, students and newcomers to the profession who are seeking to acquire a solid grounding in colour technology, as well as experts wishing to deepen, extend or refresh their knowledge.
The Value : This book provides a comprehensive state-of-the-art survey of relevant industrial colour applications and explains the various physical physiological aspects of pigment optics. Colour problems discussed in this book include the optics and chemistry of solid-colour and effect pigments, colorant formulation, optical microscopy of effect colour shades for pigment identification, methods of elementary
and advanced colorimetry, measurement and visual assessment of solid and effect colour shades, colour tolerances and acceptability, and colour-order systems. There is also a special chapter devoted to the newly emerging area of visual texture assessment of effect colour shades.Note de contenu : 1. Fundamentals of colour perception
