摘要:
Systems and methods are provided for digital printing of Braille or other raised printing. In some embodiments, ink is printed directly from a print head onto a substrate, rather than onto a transfer drum that is later printed onto a substrate. In some embodiments, a plurality of layers of a curable, phase-change ink are printed onto the substrate, wherein pauses of a predetermined time are included in between of layers to enable the curable, phase-change ink to set up into a given shape and height. In some embodiments, temperatures of printing components are lowered from those used for traditional printing, so as to enable the curable phase change ink to set up into a given shape and height. In some embodiments, spacing of components are altered from those used for traditional printing, so as to enable the curable phase change ink to set up into a given shape and height.

A solid ink composition suitable for ink jet printing, including printing on coated paper substrates. In embodiments, the solid ink composition comprises both a crystalline component and an amorphous component, and optionally, a colorant, which provides for a robust ink.
摘要:
An ink including at least one first reactive component, at least one second component comprising a triggerable component, at least one third reactive component, and an optional colorant; wherein the at least one first reactive component and the at least one third reactive component are capable of reacting with one another to form a solid ink on a substrate; wherein the at least one first reactive component is encapsulated in a microcapsule; wherein the ink can be jetted onto a substrate and treated whereby the treatment causes the at least one triggerable component to trigger the rupture of the microcapsule thereby releasing the at least one first reactive component from the microcapsule so that the at least one first reactive component and the at least one third reactive component come into contact, react, and polymerize thereby curing the ink.
摘要:
Disclosed is an organic phase change carrier and a method for forming same, and a phase change ink including same. The organic phase change carrier comprises a colloidal dispersion of nanoparticles exhibiting a substantially uniform distribution of said nanoparticles discretely distributed therewithin, at least one curable monomer; a phase change inducing component, and an initiator. The organic phase change carrier exhibits a substantially uniform distribution of the nanoparticles so that they are discretely distributed therewithin, and are substantially resistant to the aggregation of the nanoparticles distributed therewithin.

摘要:
A process including selecting an ink having a viscosity that varies continuously over a range of transfuse process temperatures; forming an image on a preliminary receiving surface or on a final receiving substrate with the selected ink; providing a final receiving substrate at a selected temperature optionally comprising modifying the temperature of the final receiving substrate to achieve a selected temperature; optionally passing the final receiving substrate through a nip; optionally exerting pressure on the final receiving substrate in the nip to transfer the ink image from the preliminary receiving surface to the final receiving substrate; optionally fusing the ink image onto the final receiving substrate at a transfuse temperature; and controlling the viscosity of the ink during printing to match a selected characteristic of the final receiving substrate; and preserving the ink image.
摘要:
An ink preferably used in piezoelectric ink jet devices includes an ink vehicle that includes at least one curable monomer, at least one polymerizable organic gelator, at least one initiator, at least one colorant and optionally at least one low molecular mass non-reactive organic gelator and/or at least one thermal solvent. The use of the curable gelator enables the ink to form a gel state having a viscosity of at least 102.5 cps at very low temperatures of about 30° C. to about 50° C. The ink may thus be jetted at low temperatures of about 50° C. to about 90° C. The ink is heated to a first temperature above the gel point of the ink, jetted onto a surface maintained at a second temperature at which the ink forms a gel state, and when on the image receiving substrate, is exposed to radiation energy to polymerize the polymerizable components of the ink.

A phase change ink including at least one crystalline component of the formula wherein R1 and R2 can be the same or different, and wherein R1 and R2 each, independently of the other, is (i) an alkyl group, (ii) an arylalkyl group, (iii) an alkylaryl group, or (iv) an aromatic group, provided that at least one of R1 and R2 is an aromatic group, and wherein the crystalline component has a melting point of from about 65° C. to about 150° C.; at least one amorphous component; and an optional colorant.
