A printing method prints an image on a leather with an ink set including a color ink and a clear ink. The printing method includes: applying the clear ink to a region of the leather where the color ink is to be applied; applying the color ink onto the clear ink applied; and applying the clear ink onto the color ink applied.

Disclosed is a substrate treating apparatus. The substrate treating apparatus may include a stage including an accommodation area, onto or from which a substrate is loaded or unloaded, and a treatment area, in which the substrate is treated, a liquid discharge head that supplies a treatment liquid to the substrate, and a liquid receiving part that receives the treatment liquid pre-discharged by the liquid discharge head in the treatment area.

An image recording method including the steps of forming an image by applying an ink to an ink receiving member and applying a treatment liquid containing an ink-viscosity-increasing component to the ink receiving medium so as to overlap with at least a part of a region of the ink receiving medium to which the ink is applied. The treatment liquid contains a surfactant which lowers a surface tension of water to 25 mN/m or less when added into the water in an amount of 0.1% by mass; and an additive containing at least one compound selected from the group consisting of compounds represented by general formulae (1) to (4):

A nonaqueous inkjet printing method that can provide prints with both high printing density and good gradation is provided. The nonaqueous inkjet printing method comprises printing an image by an inkjet recording system using a first nonaqueous ink comprising at least a coloring pigment, a water-soluble resin having an amino group, and a nonaqueous solvent, and then printing an image so as to overlap with the preceding image by an inkjet recording system using a second nonaqueous ink, wherein the second nonaqueous ink comprises at least a coloring pigment, inorganic particles, and a nonaqueous solvent, and the content of the coloring pigment in the second nonaqueous ink is lower than the content of the coloring pigment in the first nonaqueous ink. The first nonaqueous ink is preferably printed at a higher resolution of printing than the second nonaqueous ink.

An overcoating liquid contains a hydrodispersible polyurethane; a compound represented by Chemical formula 1: C.sub.6F.sub.13—CH.sub.2CH.sub.2O(CH.sub.2CH.sub.2O).sub.nH, where n represents an integer of from 1 to 40; a compound represented by Chemical formula 2: HOR.sub.1R.sub.3C—(CH.sub.2).sub.n—CR.sub.2R.sub.4OH, where R.sub.1 and R.sub.2 each, independently represent alkyl groups having three to six carbon atoms, R.sub.3 and R.sub.4 each, independently represent methyl groups or ethyl groups, and n represents an integer of from 1 to 6; and water, wherein the overcoating liquid is applied to the surface of a recording medium onto which inkjet ink is already discharged.

A recording method includes applying a white ink containing a white material and a first resin onto a predetermined region of a recording medium, and applying a reaction liquid containing a reaction agent onto at least the predetermined region. Further, the recording method includes applying a clear ink containing a second resin onto at least the predetermined region, and the application of the white ink and the clear ink are performed while the white ink and the clear ink are both wet; and/or the white ink further contains the second resin. When either the first resin and water, or the second resin and water, is mixed with an aqueous solution of magnesium sulfate, the average particle size of the first resin increases more than the second resin.

The ink jet printing method includes applying an aqueous coloring ink composition onto a printing surface of a printing medium by being ejected from an ink jet head. The printing surface of the printing medium contains natural fibers and synthetic fibers.

An ejection surface extends in a first direction as a scanning direction and a second direction orthogonal to the first direction and is externally exposed. A plurality of nozzles opens at the ejection surface. A plurality of partial channels is located inside the ejection surface, and at bottom surfaces on a side of the ejection surface, the nozzles open. The plurality of nozzles is arranged in a direction intersecting with the first direction in plural rows to constitute a plurality of nozzle rows. The number of the nozzles arranged in each row is greater than the number of the plural rows. Between the nozzles in each nozzle row, the nozzles in other nozzle rows appear as seen in the first direction. A position of openings in the bottom surfaces of the partial channels differs across at least some of the nozzles in each nozzle row.

An apparatus (100) for applying a liquid to a printing surface (150). The apparatus comprise: a housing (110) arranged to receive the liquid, the housing comprising an aperture and the aperture comprising at least a first side defined by the housing and a second side defined by the housing which is opposite to the first side, such that the liquid can flow out of the housing by passing through the aperture between the first side and the second side; and a liquid guide member (120) which is inserted into the aperture so that the liquid guide member extends from the first side to the second side. The liquid guide member comprises: a first transfer surface; a second transfer surface which is separated from the first transfer surface by a gap; a first channel which extends from a first inlet which is adjacent to the aperture to a first outlet which is adjacent to the first transfer surface; and a second channel which extends from a first inlet which is adjacent to the aperture to a first outlet which is adjacent to the second transfer surface, the liquid guide member being arranged such that in use the liquid will flow along the first channel from the aperture to the first transfer surface and then transfer from the first transfer surface onto the printing surface, and the liquid will flow along the second channel from the aperture to the second transfer surface and then transfer from the second transfer surface onto the printing surface as the printing surface moves relative to the apparatus.

There is provided a transfer type ink jet recording apparatus including: an image forming section forming an image by applying, onto a transfer body, a reaction liquid for increasing a viscosity of ink and ink containing an aqueous liquid medium and a coloring material; a liquid absorbing section having a porous body that absorbs at least a part of a liquid component from the formed image; a heating section heating the image treated by the porous body; a transfer section that transfers the heated image onto a recording medium; and a deterioration prevention treatment section including a deterioration preventing agent applying device that applies, onto the porous body provided in the liquid absorbing section, a deterioration preventing agent that prevents deterioration of the transfer body.
