IMAGE FORMATION WITH ELECTROSTATIC AND MOLECULAR FIXATION

An image formation device includes a first portion and a second portion. The first portion along a travel path is to receive droplets of color ink particles within a dielectric carrier fluid onto a substrate to form an image. The second portion includes a charge source to emit airborne charges to charge the color ink particles to move, via attraction relative to the substrate, through the carrier fluid to become electrostatically fixed relative to the substrate and to become additionally fixed, in their electrostatically fixed position, via distance-dependent, molecular forces relative to the substrate. The duration of additional fixation via distance-dependent, molecular forces may be at least greater than a duration of the electrostatic fixation.

INKJET PRINTING METHOD AND INKJET PRINTING DEVICE
20220371335 · 2022-11-24 ·

An inkjet printing method forming a decorative printed layer having a three-dimensional texture on a printing surface is described. The inkjet printing method includes: printing dots of curable ink that cure under a predetermined condition based on dot pattern data indicative of printed positions of the dots to be printed on the printing surface; and curing the printed dots. The dot pattern data indicates that: a distance between the adjacent dots becomes a distance where the adjacent dots before the curing are allowed to be maintained independently without bonding to one another in a first region; and the distance between the adjacent dots becomes a distance where the adjacent dots before the curing bond to one another in a second region different from the first region. Such a method may allow forming a decorative printed layer having a three-dimensional texture with a desired gloss level.

INK SET AND IMAGE RECORDING METHOD

An ink set including an ink containing water, a pigment, a pigment dispersion polymer A, and a water-soluble polymer B, and a treatment liquid containing water and at least one selected from the group consisting of a polyvalent metal salt, an acidic compound, and a cationic polymer, in which the pigment dispersion polymer A contains a specific acid group and an aromatic ring, and the water-soluble polymer B contains a specific acid group and a constitutional unit represented by General Formula (1), and in the ink, a mass ratio of a content concentration of the water-soluble polymer B to a content concentration of the pigment dispersion polymer A in a liberated polymer is 1.6 or more, and an image recording method. R.sup.1 represents a hydrogen atom or a monovalent substituent, Y.sup.1 represents a monovalent substituent, A.sup.1 represents —O—, and L.sup.1 is a divalent linking group.

ULTRAVIOLET CURABLE INKJET INK SET AND PRODUCTION METHOD OF PRINTED MATTER

By the use of an ultraviolet curable inkjet ink set for a line head printer comprising a lower layer ink containing a polymerizable monomer having a specific structure, and, a specific photopolymerization initiator, and an upper layer ink containing a polymerizable monomer having a specific structure and a specific photopolymerization initiator, wherein among the lower layer ink and the upper layer ink, one of the inks is a white ink and the other ink is a black ink, a good printed matter having excellent adhesion between a recording medium and the ink layer, and, between different ink layers can be obtained without generating curing wrinkles and curling over time even during high speed printing.

Spot gloss and gloss control in an inkjet printing system

Embodiments of the invention provide a technique that effects spot gloss or gloss control and/or variations on one image without requiring clear inks. This is preferably accomplished by use of a multilayer printing process in which an image is first printed using a first set of color print heads and then cured, and in which the image is again printed using a second set of color print head, but where the image remains uncured for a predetermined interval to allow the ink drops applied to the media to spread and thus introduce a gloss effect.

Ink composition for inkjet printed steel plate, inkjet printed steel plate using the same, and method for producing inkjet printed steel plate

Provided is an ink composition for an inkjet print steel plate, an inkjet print steel plate using the same, and a method for producing an inkjet print steel plate. The ink composition comprises: a linear acrylate-based oligomer; a reactive acrylate-based monomer; an ultraviolet curable initiator; at least one selected from the group consisting of a dye and a pigment; and at least one selected from the group consisting of an antioxidant, an antifoaming agent, and a dispersant.

Copper ink
11505712 · 2022-11-22 ·

A copper-based ink contains copper hydroxide and diethanolamine. The ink may be coated on a substrate and decomposed on the substrate to form a conductive copper coating on the substrate. The ink is low cost and micron-thick traces of the ink may be screen printed and thermally sintered in the presence of up to about 500 ppm of oxygen or photo-sintered in air to produce highly conductive copper features. Sintered copper traces produced from the ink have improved air stability compared to traces produced from other copper inks. Sintered copper traces having sheet resistivity of about 20 mΩ/□/mil or less may be obtained for 5-20 mil wide screen-printed lines with excellent resolution.
