Definitions

  • Ink jet printing is a non-impact method in which in response to a digitally produced signal, a drop of ink is ejected form a small orifice onto a substrate. Each drop produces one picture element (pixel) of the printed image.
  • These small orifices being only 10 to 60 micrometers in diameter are very susceptible to clogging, which destroys the functionality of the entire printer. If the ink is not completely stable,

  • pigments In contrast to dyes, pigments give desired image qualities because they are
  • pigments Since the pigment does not migrate on or in the media, image quality will not vary from one quality of media to the next. Also, pigments, being larger particles, are typically more opaque and denser than dyes. While these qualities may not always be wanted for colored inks, these qualities promote high quality black ink image qualities.

Abstract

La composition d'encre décrite ici convient aux imprimantes à jet d'encre des technologies thermique, piézo-électrique et continue. Elle comprend un support aqueux, un pigment colloïdal chargé négativement afin d'éviter la sédimentation dudit pigment et un dendrimère polyamidoamine renforçant la résistance à l'eau. On peut aussi ajouter à la formule de l'encre des agents appropriés, humectants et tensioactifs, et des biocides. Ces encres présentent une bonne tenue à l'évaporation, une bonne stabilité à l'entreposage, et permettent d'optimiser la qualité d'impression.
