A method for producing an object includes forming and laying N unit layers into which an object is divided, sequentially from a first layer to an Nth layer, using a resin material as a material, or using a resin material for implementing a step, to form the object, the method including performing a discharge treatment at either or both of a timing while forming a unit layer among the N unit layers, and a timing after forming the unit layer, but before starting forming a next unit layer among the N unit layers.

Method for producing object

An ink jet printer includes a transport mechanism that transports a medium in a first direction; and a carriage that includes a plasma irradiation mechanism, which emits plasma generated in a discharge portion from a plasma irradiation port and then irradiates at least a part of the medium with the plasma, and a head which ejects ink onto the part of the medium which is irradiated with the plasma, and that moves in a second direction intersecting with the first direction, in which the plasma irradiation mechanism is provided on one side of the head in the second direction, and the discharge portion of the plasma irradiation mechanism is disposed so as not to come in contact with the medium.

Ink jet printer and printing method

A liquid container according to an aspect of this invention has a containing chamber in which a liquid which temporarily generates gas by a chemical change of contained components is contained, a circulation port which communicates with the containing chamber and circulates the liquid, and a valve provided in such a manner as to connect the containing chamber to the outside thereof, in which the hydrogen penetration amount of a member partitioning the containing chamber is 0.0001 ml/cm&#xb7;day&#xb7;atm or more and 0.01 ml/cm&#xb7;day&#xb7;atm or lower per day and at least one kind of the contained components can be a base metal pigment.

Liquid container

A liquid container according to an aspect of this invention is a liquid container which is packaged with a packaging body, in which the liquid container has a containing chamber in which liquid which temporarily generates gas by a chemical change of contained components is contained, the hydrogen penetration amount of a member partitioning the containing chamber is 0.0001 ml/cm&#xb7;day&#xb7;atm or more and 0.01 ml/cm&#xb7;day&#xb7;atm or lower per day, the hydrogen penetration amount of the packaging body is equal to or larger than the hydrogen penetration amount of the member partitioning the containing chamber, and the vapor penetration amount of the packaging body is lower than the vapor penetration amount of the member partitioning the containing chamber.

An ink jet recording method according to an aspect of this invention includes discharging an ink composition containing a metallic pigment to a recording medium using a recording head, and then recording a metallic image in a recording region of the recording medium, in which particles of the metallic pigment have a plate shape and have a coating layer on the surface, the average particle diameter in the ink composition is 0.5 &#x3bc;m or more and 2 &#x3bc;m or less, the total film thickness including the coating layer is 10 nm or more and 50 nm or less, and the average number of the laminated metallic pigment particles in the metallic image is 3 or more and 30 or less.

Ink jet recording method and recorded matter

A liquid container may be connected to a liquid consuming unit. The liquid container includes an ink holder containing an ink composition, and an ink delivering portion through which the ink composition flows out of the ink holder. The ink composition contains an aqueous medium and a water-resistant metal pigment that includes pigment particles whose surfaces are covered with a coating and reacts with the aqueous medium to generate hydrogen gas. The amount of hydrogen gas generated per day from the ink composition in the ink holder is lower than or equal to the amount of hydrogen gas permeating per day through the ink holder, in an environment of 25&#xb0; C.

Liquid container and liquid container set

A recording apparatus includes a head, wherein a manifold in which an ink flows, and a plurality of ink flow paths divided from the manifold and arranged in a first direction are formed in the head; a nozzle opening portion discharging the ink flowing from the manifold is formed in the ink flow path; when a maximum area is Cand a minimum area is Cin a cross section of the ink flow path including the first direction and a vertical direction, except a cross section including the nozzle opening portion, the Cis more than once and equal to or less than 3.5 times the C; and the ink contains a flaky pigment having an average thickness of 5 nm or more and 50 nm or less and a 50% average particle diameter of an equivalent circle diameter of 0.5 &#x3bc;m or more and 2.1 &#x3bc;m or less.

Ink jet recording apparatus and recorded matter
