Lightfast colorants for ink jet applications / Wolfgang Bauer in PAINTINDIA, Vol. XLIX, N° 10 (10/1999)
[article]
Titre : Lightfast colorants for ink jet applications Type de document : texte imprimé Auteurs : Wolfgang Bauer, Auteur ; Dieter Baumgart, Auteur ; Hans-Tobias Macholdt, Auteur ; Walter Zoeller, Auteur Année de publication : 1999 Article en page(s) : p. 81-84 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Encre Formulation ‘Colorant organique’ ‘Pigment minéral’ ‘Impression jet d’encre’ Index. décimale : 667.9 Revêtements et enduits Résumé : During the last decade inkjet printing has emerged as one of the most important reprographics technologies providing high quality output at low cost. For recent multicolor industrial applications such as wideformat color graphics and near-photographic color imaging there is a growing demand for lightfast colorants. Developing water soluble dyes showing optimal fading resistance and good water fastness has proved a difficult target. In this paper, a survey of yellow, magenta, cyan and black ink jet dyes is presented including spectroscopic features, aggregation behavior and the development of lightfast polycyclic dyes. By tailoring the solid state properties, organic color and carbon black-based pigments are obtained exhibiting superior light fastness and small particle size distribution.

PigmentsIndex. décimale : 667.9 Revêtements et enduits Résumé : Modern chemistry and innovative processes have made tailor-made pigments for inkjet printing available. Practically all customer requirements can be met by modification during pigment synthesis and specific post-treatment. It is therefore not surprising that inkjet printing is increasingly replacing conventional processes in the large format sector and is becoming established in completely different areas such as packaging.

PigmentsIndex. décimale : 667.4 Encres Résumé : The two most important processes are ink-jet printing and electrophotographic printing. How electro-photographic printing works, the improvements being explored and the challenges facing pigment manufacturers are the subjects of this article by the author.
The term Non-Impact-Printing (NIP) is used for the manufacture of printing products which use no real printing forms (printing plate, printing block, etc.). Usually, in this case, a digitally-generated print image is transferred to a printing material with the aid of an NIP process. Xerography describes the process by which an image is built up electrostatically and subsequently developed through covering with electrostatically charged powder. This is the principle, also known as electrophotographic printing, on which many modern copiers, laser printers or faxes work. Today, these items of equipment are to be found in every office and have thoroughly revolutionised day-to-day office like in the last 15 years. Increasingly, the process is also being employed for textile printing, small print runs of industrial printing or digital print images[1,2,3]. Table 1 gives an estimate of global toner volumes and machine placements[4] for the electrophotographic printing process. The market growth is driven by technology. Most key players like Hewlett-Packard, Canon, Lexmark, and Xerox are active with both toner and ink jet technologies.Note de contenu : - How do printers and copiers work ?
