Ink jet recording method and ink jet recording apparatus
An ink jet recording method includes a treatment liquid attachment step, in which a treatment liquid is attached to a recording medium, and an ink attachment step, in which a water-based ink composition is attached to the recording medium. An ink jet recording apparatus includes a recording medium support and a heating mechanism that heats the recording medium support. The ink attachment step is carried out with the recording medium supported and heated by the recording medium support. In the ink attachment step, the recording medium is heated so that a surface thereof reaches a maximum temperature of 28.0° C. or more and 45.0° C. or less. The ratio between absorbances A and B (A/B) is 0.5 or more and 0.95 or less, where absorbance A is that of a 0.1% by mass mixture of the water-based ink composition in the treatment liquid, and absorbance B is that of a 0.1% by mass mixture of the water-based ink composition in purified water. The recording medium support has a flat support surface for supporting the recording medium.
Fixing unit and method for fixing a print image on a recording medium
A fixer includes a fixing roller around which a recording medium is directed such that the print image to be fixed faces toward the shell surface of the fixing roller. A fixing gap is generated with a gaseous fixing medium between the shell surface of the fixing roller and the recording medium. This advantageously produces an efficient and gentle fixing of the print image.
Substrate treating apparatus and inkjet apparatus
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.
Treatment Method
A treatment method according to an embodiment of the present disclosure includes: a first treatment agent adhesion step of ejecting a first treatment agent which contains a pigment, first resin particles, water, and a first water-soluble organic solvent from an ink jet head so as to be adhered to a cloth; and a second treatment agent adhesion step of spraying a second treatment agent which contains second resin particles, water, and a second water-soluble organic solvent from a nozzle front hole together with a heated gas to the cloth to which the first treatment agent is adhered so as to be adhered thereto, and the nozzle front hole has a temperature higher than a standard boiling point of the second water-soluble organic solvent by 50° C. or more.
LIQUID COMPOSITION, LIQUID DISCHARGING DEVICE, AND METHOD OF MANUFACTURING LIQUID COMPOSITION
A liquid composition contains a coloring material, an organic solvent, a compound represented by Chemical Formula 1 below, a resin, and water, wherein the contact angle of water against a liquid composition film formed by attaching the liquid composition to a non-permeable printing medium is 60 degrees or less,
##STR00001## where n represents an integer of from 4 to 10.
PRECOATING AGENT, IMAGE FORMING METHOD, AND IMAGE FORMING APPARATUS
The present invention provides a precoating agent which is used in an image forming method using an active ray curable ink and which is applied to a surface of a recording medium before the active ray curable ink is applied, the precoating agent comprising a crystalline resin and an active ray polymerizable compound.
IMAGE FORMING APPARATUS
An image forming apparatus includes: a pretreatment section that applies a precoat liquid to a printing surface of a continuous recording medium to be transported; a printing section that sprays ink onto the continuous recording medium to which the precoat liquid is applied; and a transport section that transports the continuous recording medium along a predetermined path. The transport section includes at least one pass roller that is disposed between the pretreatment section and the printing section, the pass roller transporting the continuous recording medium to which the precoat liquid is applied toward the printing section and coming into contact with the printing surface of the continuous recording medium. A surface of the pass roller is subjected to water-repellent finishing for the precoat liquid.
METHOD FOR PRODUCING A RELIEF-LIKE PRINTED IMAGE ON CONTAINERS
A method for producing a relief-like printed image on containers is described in which print layers are layered onto one another by way of jet application of a printing paint, an ink, a varnish, or an adhesive from at least one print head onto a container, thereby producing elevated regions of the printed image. Due to the fact that the print layers are each applied in full tone printing, optical and haptic effects can be created on container surfaces with low equipment complexity and a minimal number of printing steps.
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.
