Résumé : |
During the last decade the development of non-impact printing technologies including laser, thermal and ink jet printing has made considerable progress. Among these reprographic methods, ink-jet devices have a high market potential due to their colour capability. Ink-jet applications include monochromatic and colour office printers, photographic-imaging systems and industrial printers for marking, coding and addressing. There are two basic means of projecting ink drops onto surfaces: continuous and drop-on-demand ink-jet. Together with hardware design and paper quality, dyes in ink formulations play an important role in the operation of ink-jet systems. The properties required of water-soluble ink-jet dyes, which are summarised in Figure 1, constitute some of the most important factors that contribute to the ultimate print quality.Significant for the primary colours yellow, magenta and cyan, utilised in subtractive colour system are peak wavelength, narrow absorption curves and the absence of secondary absorptions.For monochromatic printers and systems using the four-colour technology a neutral black is needed additionally. The innovations which are necessary to meet the specific requirements for dyes in ink-jet systems are reflected by the great number of patent applications. The subjects of these patent applications demonstrate that i the first phases of development, conventional dyes for the paper and textile industries were selected. In the second phase, starting in 1985, the development of dyes with improved properties for ink-jet applicationshas been observed. However, by developing and producing new dyes, development and the costs of patenting have to be considered as well as the prospective volume of dyes and the life cycle of the printer. |
