A water-based ink for use in an ink jet printer for printing machine-readable indicia on a substrate is disclosed. The ink jet ink comprises fluorescent nanoparticles having a diameter between about 30 nm and about 100 nm; and an aqueous liquid vehicle. The aqueous liquid vehicle comprises water and a water soluble vehicle in sufficient amounts to achieve an ink viscosity and surface tension effective for application of the ink jet ink to the substrate in a predetermined pattern by ink jet printing.
Encre à base d'eau utilisable dans une imprimante à jet d'encre pour l'impression d'un marquage lisible par machine sur un support. L'encre comprend des nanoparticules fluorescentes d'un diamètre de 30 nm à 100 nm environ, et un véhicule liquide aqueux contenant de l'eau et un véhicule soluble dans l'eau de quantité suffisante pour obtenir la viscosité de l'encre et une tension superficielle efficace pour appliquer l'encre au support selon un motif préétabli, lors de l'impression au jet d'encre.
