摘要:
Methods of controlling gloss of an image are disclosed. The methods may include forming an image over a substrate by applying an ink composition and optionally an overcoat composition at least partially over the substrate. The ink composition or overcoat composition may include at least one gellant, at least one curable monomer, optionally at least one curable wax and optionally at least one photoinitiator. The ink composition or overcoat composition may be curable upon exposure to radiation. The methods may further include providing a micro-roughness to one or more portions of the ink composition or overcoat composition by non-uniformly curing the ink composition or overcoat composition, and flood curing the ink composition or overcoat composition to complete a cure. The methods may thereby provide a controlled gloss level to the image.
摘要:
The radiation-curable phase-change ink composition having at least one radiation curable fluorescent co-monomer and a gellant. The radiation-curable phase-change in composition offers both document security features as well as potential brand highlight features. The radiation-curable phase-change ink composition combines the unique attributes of the UV curable gel system, with its tremendous substrate latitude, with the ability to add tunable fluorescent effects without the safety concerns of small molecule fluorescent additives. Exemplary ink compositions include a first co-monomer, least one radiation curable fluorescent co-monomer, and a gellant. Methods for making and using these ink compositions and ink compositions are also provided.
摘要:
Disclosed herein are methods of using inks with gellants, that can form a gel state, as receivers for particle materials. The inks are liquid when jetted, but quickly enter a tacky/semi-solid/gel state when cooled below ink gel temperature on a substrate and prior to curing. Dry powders and solid particulate substances of various types are then applied to the jetted inks and locked in place when the ink is cured.

A method of controlling gloss of an image includes forming an image over a substrate by applying a colored or colorless composition, included a colored ink and/or a colorless overcoat composition, over one or more portions of the substrate, wherein the colored or colorless composition includes at least one gellant, at least one curable monomer, at least one curable wax and optionally at least one photoinitiator, wherein the colored or colorless composition is curable upon exposure to radiation, and curing the colored or colorless composition following application by applying radiation to the colored or colorless composition and, during the curing, controlling an amount of oxygen present in an atmosphere around the image.
摘要:
A substantially colorless radiation overcoat composition suitable for overcoating ink-based images and xerographic-based images. The overcoat composition comprises at least one gellant, at least one monomer, at least one substantially non-yellowing photoinitiator, optionally a curable wax, and optionally a surfactant.
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:
A reactive ink set including three mixtures of radically polymerizable monomers. A first mixture includes a peroxide, a second mixture includes a peroxide decomposition agent, and an optional third mixture that does not include a peroxide or a peroxide decomposition agent. The first mixture and the second mixture polymerize to form a solid ink on the substrate following jetting in the liquid state.
摘要:
Radiation curable phase change ink comprising an ink vehicle that includes at least one curable carrier, at least one gellant, at least one curable wax and at least one photoinitiator. In a method of forming an image with the ink, the radiation curable phase change ink is melted, then jetted onto an image receiving substrate, wherein the radiation curable phase change ink forms a gel state, and exposed to ultraviolet light to cure the curable components of the radiation curable phase change ink. The wax cures into the structure of the ink, thereby generating a robust image of excellent gloss.
