Colour measurement from many angles / Gerhard Pfaff ; Peter W. Gabel in EUROPEAN COATINGS JOURNAL (ECJ), N° 06/2005 (06/2005)  

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 06/2005 (06/2005) . - p. 30-33 Titre : Colour measurement from many angles : Modern effect pigments require multiple instrument geometries Type de document : texte imprimé Auteurs : Gerhard Pfaff, Auteur ; Peter W. Gabel, Auteur Année de publication : 2005 Article en page(s) : p. 30-33 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Testing methods - Recently developed colour effect pigments exhibit a much wider range of colour shifts than classical metal and mica flake pigments. These novel effects cannot be measured adequately on conventional instruments. It is shown that multiple measuring geometries are required, and results from a new instrument operating in this way are presented. These measurements are considered to corrolate welll with visual assessment.

A matter of precision / Peter W. Gabel in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 194, N° 4463 (04/2003)

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 194, N° 4463 (04/2003) . - p. 18-19 Titre : A matter of precision Type de document : texte imprimé Auteurs : Peter W. Gabel, Auteur Année de publication : 2003 Article en page(s) : p. 18-19 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Colorimétrie Pigments à effets spéciaux Index. décimale : 535.6 Couleur Résumé : Continued improvement in instrument performance is vital if colour measurement techniques are to keep abreast of customer demands explains the author. Many industries, notably the automotive, printing, plastics and cosmetics industry, would not be what they are today if it were not for special effect pigments. At one time the first-generation classic effect pigments were all the rage, but now designers and stylists are crying out for the latest special-effect pigments. They are used to make an object distinctively appealing and fulfill this requirement admirably because of their gonioapparent nature. For example the change in their appearance with the change in angle of illumination or view. Looking at the past, stylists started with conventional metal pigments, like aluminium or bronze pigments, followed by pearlescent pigments, also know as mica pigments, pearl pigments or mineral effect pigments. In the last two years a new generation of effect pigments has become more and more popular. They are based on innovative substrates, like silica flakes or alumina flakes, ultra-thin multilayer interference film flakes or liquid crystals in organically crosslinked polymers.

Measuring special effects / Werner Rudolf Cramer in EUROPEAN COATINGS JOURNAL (ECJ), N° 7-8/01 (07-08/2001)  

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 7-8/01 (07-08/2001) . - p. 34-39 Titre : Measuring special effects Type de document : texte imprimé Auteurs : Werner Rudolf Cramer, Auteur ; Peter W. Gabel, Auteur Année de publication : 2001 Article en page(s) : p. 34-39 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Like other things effect pigments are advancing. A new second generation of effect pigments has been developed which gets more and more attention of stylists and designers for Industrial applications. This latest generation of effect pigments requires a totally different system of measurement and characterisation. The capabilities of various spectrophotometers available for this purpose are discussed. Note de contenu : - Interference - colour by physics - Colour shift depends on light and illumination angle - Visual judgement of effect pigments - Multi-angle measurements - absolutely essential - Spectrophotometers - an angle-dependent overview - The results - more than just numbers - The issues - and a pragmatic solution En ligne : https://drive.google.com/file/d/1d_mxgnmwKRoYkaEzAsA2qk9iXPyNmuqX/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=10948 [article]
