H. Hutchinson, Auteur Année de publication : 1995 Article en page(s) : p. 188-194 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Encre  'Impression  plat'  Lithographie  Formulation  Durcissement  Séchage  'Article  synthèse' Index. décimale : 667.9 Revêtements et enduits Résumé : The emphasis has been on lithographic inks and associated materials that give best quality printing results combined with the high productivity of today's printing presses. Additionally the inks have to meet the specific needs of a wide wariety of substrates udes in publication and packaging printing-papers, carton boards, metals and plastics - also to be compatible with the significant advances in press machinery and associated aquipment technology. There are continuing constraints brought about by ever increasing pressures of legislation. Much of this concerns environmental issues, aspects of health and safety and the welter of labelling, packaging and consumer protection regulations. Then there have been the continuing uncertainties in the economic climate worldwide. All the above mentioned factors have a bearing on progress. After touching on some of the significant developments and events, the intention is to discuss come work that the author has carried ouf on the absorption of vegetable oils and solvents by paper substrates.

Non-impact printing processes / J. W. Davison in SURFACE COATINGS INTERNATIONAL, Vol. 78, N° 5 (05/1995)

[article]  inSURFACE COATINGS INTERNATIONAL > Vol. 78, N° 5 (05/1995) . - p. 196-202 Titre : Non-impact printing processes Type de document : texte imprimé Auteurs : J. W. Davison, Auteur Année de publication : 1995 Article en page(s) : p. 196-202 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Encre  'Impression  sans  contact'  Electrophotographie  Magnétographie  transfert'  'Article  synthèse'  'Jet  encre' Index. décimale : 667.9 Revêtements et enduits Résumé : All of the traditional printing processes require pressure to transfer ink to paper. In 1937 Chester Carlton patented a system of printing that relied on the principles of electrostatics to transfer ink to paper. There was no pressure or impaction involved in the production of the print. The process became known as Xerography and the era of non-impact printing was born. Xerography is now more generally known as Electrophotography ant the device is described as a machine or engine rather than a printing press.

A study of writing delivery systems development and associated ink formulations / A. C. Davey in SURFACE COATINGS INTERNATIONAL, Vol. 78, N° 5 (05/1995)

[article]  inSURFACE COATINGS INTERNATIONAL > Vol. 78, N° 5 (05/1995) . - p. 204-208 Titre : A study of writing delivery systems development and associated ink formulations Type de document : texte imprimé Auteurs : A. C. Davey, Auteur ; James Thomas Guthrie, Auteur Année de publication : 1995 Article en page(s) : p. 204-208 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Encre  Utilisation  Ecriture  Formulation  Stylo Index. décimale : 667.9 Revêtements et enduits Résumé : In the literature, ink-related articles are generally concerned with inks for use by the mainstream printing processes. Each of these processes has its requirements. One of these concerns the nature of the inks being deposited. Although many of the papers on ink characterisation are of general interest, relatively little coverage has been specifically given to speciality ink formulations and their application. One such example is that of the formulation, composition, nature and behaviour of writing fluids for use in the various types of pens and markers available today. These inks are designed with a particular delivery system in mind. Typical examples are the fountain pen, the ball-point pen, the felt-tip pen and roller ball pen types. Each delivery system performs the "printing operation" in a particular way i.e transfers ink from the supply to the substrate. It therefore follows that, to attain performance, each delivery system makes a number of highly specific and very different demands on the appropriate writing fluid. It is certainly an area worthy of study as the market for writing instruments was worth $3.5 billion in 1985 and even more today.

Odour emission to atmosphere from two-piece beer and beverage can manufacturing plants / J. W. Casper in SURFACE COATINGS INTERNATIONAL, Vol. 78, N° 5 (05/1995)

[article]  inSURFACE COATINGS INTERNATIONAL > Vol. 78, N° 5 (05/1995) . - p. 210-216 Titre : Odour emission to atmosphere from two-piece beer and beverage can manufacturing plants Type de document : texte imprimé Auteurs : J. W. Casper, Auteur ; R. P. Redman, Auteur Année de publication : 1995 Article en page(s) : p. 210-216 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Emission  polluant'  Odeur  'Usine  fabrication'  Bidon  Laquage  'Composé  volatil'  'Pollution  air'  organique' Index. décimale : 667.9 Revêtements et enduits Résumé : Most industrialised nations have now enacted environmental protection regulations primarily aimed at reducing the volatile organic compounds ( VOC ) emitted to atmosphere. Whilst there may be little obvious immediate benefit of their implementation to those living in the neighbourhood of VOC emitting factories, what does make an immediate impact is odour emission and particulary any changes in odour. The UK Environmental Protection Act requires that the aim should be that all emissions are free from offensive odour outside the process boundary , as perceived by the local authority Inspector'. This paper is concerned with the emissions to atmosphere, and in particular odour emissions, from the lacquering processes associated with two-piece beer and beverage can manufacture. Despite steady progress in VOC reduction from such processes by the adoption of water-borne lacquer systems, odour nuisance complaints do occur from time to time. In this paper we estimate the magnitude of the VOC and odour problem using know parameters of the lacquering process and then compare this with experimentally determined odour measurements of actual lacquers.
