摘要:
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 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:
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; wherein the ink jet print head jets an ultra-violet curable phase change ink composition comprising an optional colorant and a phase change ink vehicle comprising a radiation curable monomer, or prepolymer; a photoinitiator; a reactive wax; and a gellant; wherein a print deposited upon the print region surface is Braille, raised print, or a combination of regular print and one or both of Braille and raised print.

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.
摘要:
An ink set is made up of at least three differently colored phase change inks, for example cyan, magenta and yellow, wherein at least one of the colored phase change inks is a photochromic ink that contains a photochromic material. Upon exposure to activating radiation such as ultraviolet light, the at least one photochromic ink changes to a color different from the color of the photochromic ink prior to exposure to the activating radiation.
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.
