A textile printing is more appropriately performed on fabrics made from various materials. A textile printing method of performing textile printing on a textile printing object which is a fabric includes a dye adhesion process of adhering particles of a polyester resin which is a particulate polyester resin, and a dye to the fabric, and a heating process of heating the textile printing object having the particles of the polyester resin and the dye adhered thereto, thereby developing the color of the dye while fixing the particles of the polyester resin to the textile printing object.

Textile printing method, textile printing device, ink, and medium for transfer

The aim is to form a print pattern remarkably glossy and quick-dry for efficient cure of inks. An inkjet printing device is provided that includes a controller. The controller prompts a UVLED unit to emit ultraviolet light to precure inks of an ink set discharged from an inkjet head unit by irradiating the inks with ultraviolet light. The controller further prompts the UVLED unit to irradiate the precured inks with ultraviolet light. The ink set includes color UV inks each containing an ultraviolet-curable resin and a colorant but containing no metallic particle, and a solvent UV ink containing an ultraviolet-curable resin, a solvent, and metallic particles.

The disclosure provides an inkjet printer capable of reducing yellowing of a coating attributable to clear ink with respect to printing on a print medium with color ink. An inkjet printer () having LED lamps () for hardening color ink and an ultraviolet lamp () for hardening clear ink ejects ultraviolet curing type color ink toward a print medium () by inkjet heads () for color ink, and radiates ultraviolet light with a wavelength equal to or longer than 365 nm toward the color ink having adhered to the print medium () by the LED lamps (), and ejects ultraviolet curing type clear ink toward the hardened color ink by inkjet heads () for clear ink, and radiates ultraviolet light with a wavelength equal to or shorter than 365 nm toward the clear ink having adhered to the color ink by the ultraviolet lamp ().

A laminate is provided that includes a metallic ink layer having excellent glossiness. A method for producing a laminate includes forming a metallic ink layer by irradiating ultraviolet light to a metallic ink applied onto a medium, forming a smoothing ink layer by applying a smoothing ink onto the metallic ink layer after forming the metallic ink layer, and forming a color ink layer by applying a color ink onto the smoothing ink layer.

Method for producing laminate including metallic ink layer

Water-based ink having characteristics of a metal nanoparcile or metal ion and substantially reduced aggregation is provided. The water-based ink includes a metal compound in which an organic ligand is coordinated to a metal nanoparticle and/or a metal ion, and a coloring pigment and/or a coloring dye.

Water-based ink

A printing apparatus in which printing is performed using an ink jet method includes a first ink jet head that discharges ink droplets of ink of a first color which is a color of the same color type as an expression color that is set in advance, a second ink jet head that discharges ink droplets of ink of a second color which is a color of the same color type as the expression color and is different from the first color, and a control unit which makes the first and the second ink jet head perform printing with the expression color on a medium by setting a ratio of a discharge amount of ink of the first color by the first ink jet head to a discharge amount of ink of the second color by the second ink jet head to a discharge rate which is calculated in advance.

An ink is provided that does not easily cause an offset or blocking upon winding a print, even when the ink contains a lactic acid ester or a lactone solvent. In order to solve such a problem, the ink of the present invention includes: a colorant; and a ketone compound of the following general formula (1),R&#x2014;CO&#x2014;R&#x2003;&#x2003;(1),wherein Rand Reach independently represent an alkyl group of 1 to 10 carbon atoms, where the total number of carbon atoms in Rand Ris 5 to 11, and Rand Rmay form a ring when the sum of the carbon atoms in Rand Ris 6 or more.

A nozzle plate for an inkjet head including a substrate and ink ejecting holes formed in the substrate. An ink-repellent layer is formed on an ink ejecting side surface of the nozzle plate, and portions of the ink-repellant layer around the ink ejecting holes are selectively removed so that portions of the nozzle plate around the ink ejecting holes are exposed. Also, a method of producing a nozzle plate for an inkjet head is provided that includes preparing a nozzle plate which includes a substrate and ink ejecting holes formed in the substrate and has an ink-repellent layer formed on an ink ejecting side surface of the nozzle plate, and selectively removing portions of the ink-repellant layer around the ink ejecting holes to expose portions of the nozzle plate around the ink ejecting holes.

An antipenetrating agent is to be added to a solvent ink for preventing penetration of the solvent ink into a medium to be printed. The antipenetrating agent includes inorganic fine particles and a resin soluble in an organic solvent.

Antipenetrating agent, solvent ink for inkjet printing and printing method

A coating agent for use in UV curable inkjet printing using nonaqueous UV ink. The coating agent includes a main component that is an organic-inorganic nanocomposite, and the coating agent is configured to form an undercoat before the inkjet printing or to form a finishing coat after the inkjet printing and UV curing.

Coating agent for UV curable inkjet printing

A non-water-based inkjet ink containing a colorant, is characterized in that a mixed solvent having a solubility parameter value of from about 8 to about 10 is used as a solvent. The ink is an inkjet ink of which solvent hardly erodes a head member so as to allow long term stable printing and also hardly penetrates the material of media so as to improve the printing quality.

A penetration inhibitor includes a rosin-series resin having weight-average molecular weight of at least about 16,000 and at most about 50,000. The penetration inhibitor is to be added to a solvent ink for an inkjet printer.

Penetration inhibitor, method for preventing penetration of solvent ink, solvent ink for injket printer and method for producing the solvent ink

An inkjet ink containing a colorant, where an amine compound is added as a pH adjuster. The ink is capable of preventing the pH of the ink from being shifted to the acidity side due to corrosive substances (e.g., acid substances) generated by deterioration of ink, adverse effects due to water absorption and moisture absorption, or degradation of resin (e.g., degradation of vinyl chloride-vinyl acetate copolymer resin), thus preventing erosion of a head nozzle member.
