摘要:
An ink set includes a plurality of inks, at least one ink but less than all inks of the ink set including an ink vehicle, colorant and fluorescence agent and remaining additional inks including an ink vehicle, colorant and free of fluorescence agent. At least a first ink grouping and a second ink grouping of the ink set form a combination, the first and second groupings of the combination exhibiting a substantially same color under ambient light conditions upon image formation. The first ink grouping and the second ink grouping of the combination contain a different amount of the fluorescence agent, wherein upon exposure to activating energy, the fluorescence agent fluoresces to cause a visible change in the color of a pattern formed in an image by the first ink grouping as compared to the second ink grouping.

Disclosed is a system for embedding and recovering machine readable information on a substrate, including an image forming device containing at least two fluorescent marking materials, wherein the image forming device receives data representative of the machine readable information, and forms an image corresponding to the data in a machine readable code format with the at least two fluorescent marking materials on the substrate, and a document reading device including a radiation emitting unit that emits radiation effecting fluorescence of a first fluorescent marking material and/or second fluorescent marking material, and a reader that detects the data in the image on the image receiving substrate while the first fluorescent marking material and/or second fluorescent marking material is fluorescing.
摘要:
Disclosed is an ink jet printing device including an ink jet print head and a print region surface toward which ink is jetted from the ink jet print head, wherein a height distance between the ink jet print head and the print region surface is adjustable. The ink jet printing device is thus a dual printing device capable of printing both regular height and raised height images such as Braille.

Disclosed is a method of embedding machine readable information on a substrate, including converting the information to machine readable code format and writing the machine readable code format on the substrate with at least one fluorescent marking material. Also disclosed is a system for embedding and recovering machine readable information on a substrate, including an image forming device containing at least one fluorescent marking material, wherein the image forming device receives data representative of the machine readable information, and forms an image corresponding to the data in a machine readable code format with the at least one fluorescent marking material on an image receiving substrate, and a document reading device including a radiation emitting unit that emits radiation effecting fluorescence of the at least one fluorescent marking material, and a reader that detects the data in the image on the image receiving substrate while the at least one fluorescent marking material is fluorescing.
摘要:
Disclosed is a machine readable cord of a set of printed markings, wherein each printed marking of the set has a predetermined height on a substrate and represents a predetermined date value, wherein printed markings having a same predetermined height represent a same data value, and wherein printed markings representing different data values have different heights. Also disclosed is a system for embedding and recovering information on a substrate, including an image forming device containing at least one marking material, wherein the image forming device receives data, corresponding to the information, for forming machine readable code in accordance with claim 1 on an image receiving substrate, and forms an image including the machine readable code on the image receiving substrate with the at least one marking material, and a document reading device comprising a reader that detects the differences in height among the different printed markings of the machine readable code.
摘要:
Disclosed is a radiation curable ink containing a fluorescent material that upon exposure to activating energy fluoresces such that an image that was not visible prior to exposure to the activating energy becomes visible. Also disclosed are an ink jet system and a process printing the disclosed radiation curable ink.
摘要:
Disclosed is a phase change ink containing a fluorescent colorant that upon exposure to activating energy fluoresces such that an image that was not visible prior to exposure to the activating energy becomes visible. Also disclosed are an ink jet system and a process for authenticating a color document using the disclosed phase change ink.
摘要:
A method for making toners to include at least one nanoscale fluorescent pigment particle composition and/or a fluorescent organic nanoparticle composition. The particles are incorporated into emulsion of toner and used in making toner via emulsion aggregation. Such toners may have a core and/or a shell and the clay composites may be included within the core, the shell or both. The fluorescent organic nanoparticle composition includes a polymeric matrix obtained by modified EA latex process and/or emulsion polymerization and one or more fluorescent dyes and the nanoscale fluorescent pigment particle composition includes pigment molecules with at least one functional moiety, and a sterically bulky stabilizer compound including at least one functional group, the functional moiety of the pigment associates non-covalently with the functional group of the stabilizer, and the presence of the associated stabilizer limits the extent of particle growth and aggregation, to afford nanoscale-sized pigment particles.
