The plurality of structures include a plurality of first structures disposed in the first region and a plurality of second structures disposed in the second region. A base layer (22) is provided between the substrate and at least one of the plurality of second structures.

Provided is an aqueous ink for ink jet including a resin particle, which is capable of recording an image having satisfactory abrasion resistance while having satisfactory storage stability. The aqueous ink for ink jet includes a resin particle. The resin particle is formed of a first resin and a second resin. The first resin is a polyolefin resin having a melting point of 60°C or more to 130°C or less. The second resin is a copolymer having a unit derived from an α-olefin having 4 or more carbon atoms and a unit derived from an unsaturated dibasic acid.

The present disclosure is directed to an information processing apparatus reads, from a product, a data carrier for accessing Digital Product Passport, DPP, information of the product that is managed on a blockchain; acquires, by using information in the read data carrier, first DPP information that is DPP information of a main unit of the product that is managed on the blockchain, and second DPP information that is DPP information of one or more parts installed in the product, the second DPP information being managed on the blockchain in association with the first DPP information; and outputs a specific carbon footprint based on a carbon footprint of the product included in the acquired first DPP information and a carbon footprint of each of the one or more parts included in the acquired second DPP information.

A printing apparatus includes a discharge unit (26) configured to discharge a print medium in a first direction a stacking unit (4) configured to stack, on a stacking surface (4a), the print medium discharged in the first direction by the discharge unit (26) and a regulation unit (421) configured to regulate, on the stacking surface (4a) of the stacking unit (4), a position of a front edge of the print medium in the first direction. The regulation unit (421) is configured to change, by use of a drive source, between a first posture, in which the front edge of the discharged print medium is regulated by an abutting surface (421a) on which the front edge abuts, and a second posture, in which the front edge of the discharged print medium is not regulated.

An ink jet recording method using an ink jet recording apparatus includes a recording head (1), the recording head including: an ejection orifice (13) configured to eject an aqueous ink including resin particles; a pressure chamber (12) communicating the ejection orifice; an ejection element arranged in the pressure chamber; a liquid retention chamber configured to supply the aqueous ink to the pressure chamber; a bubble retention chamber (520) communicating to the liquid retention chamber; a decompression chamber (760) arranged adjacent to the bubble retention chamber; and a gas permeable membrane (710) arranged at a boundary between the bubble retention chamber and the decompression chamber, the method including: applying the aqueous ink to a recording medium (P); and then heating the recording medium. T_g (°C) of the resin particle, T_i (°C) of the aqueous ink in the bubble retention chamber and T_fix (°C) of the recording medium satisfy T_i<T_g≤T_fix.

A printing apparatus (1) includes: a discharge unit (26) configured to discharge a print medium in a first direction; a stacking unit (4) having a stacking surface (4a) and configured to extend and contract in the first direction and to stack the print medium discharged from the discharge unit (26) on the stacking surface (4a); a first regulation unit (421) arranged in the stacking unit (4), on a downstream side in the first direction of the stacking unit (4), and configured to regulate a position of a front edge of the print medium discharged from the discharge unit (26); and a control unit (71) configured to control extension of the stacking unit (4) prior to discharge of the print medium, in accordance with a size of the print medium to be discharged from the discharge unit (26).

A recording apparatus (501) comprises a recording means (507) recording a test pattern on a recording medium (1001), the test pattern includes a recording patch in which a color ink containing a colorant and a reaction liquid containing a reaction component that aggregates the colorant are recorded so as to overlap each other; and a region in which the color ink is recorded around the recording patch and a control means (531) setting, according to a permeation property of the reaction liquid for the medium, an application amount of the reaction liquid per unit area to record the recording patch on the medium. The control means detects a recording patch position in an image obtained by reading the medium on which the test pattern is recorded and determine, based on the recording patch position, an adjustment value for adjusting a recording position of the reaction liquid.

An information processing apparatus (102) receives a job history from an image forming apparatus (101) that performs a job to form an image on a recording medium. The job history includes information on a printing job that has been normally completed and information on a related job related to the normally completed printing job. The information processing apparatus (102) includes first and second calculation units (601), an addition unit (361), and a storage unit (363). The first and second calculation units (601) calculate the carbon dioxide emissions generated when the normally completed printing job is performed and the carbon dioxide emissions generated when the related job is performed. The addition unit (361) adds up the amounts calculated by the first and second calculation units (601). The storage unit (363) stores the sum of the amounts as a total amount of carbon dioxide emissions associated with the normally completed printing job.

An optional device connectable to a printing apparatus in multi-stage connection in one direction, comprising an auxiliary function unit configured to assist a function of the printing apparatus, and a control unit, the control unit includes an arithmetic processing unit which performs arithmetic processing for controlling the auxiliary function unit based on power received from the printing apparatus, in a case where the printing apparatus is connected to an upstream side, and a power transmission unit configured to transmit power received from the printing apparatus to another optional device connected to a downstream side, and in a case where another optional device is connected to the upstream side, the arithmetic processing unit does not perform the arithmetic processing.

A unit (100) includes a first component (1) and a second component (2). One of the first component (1) and the second component (2) is movable with respect to the other. A first surface (101) of the first component (1) includes a first region (111), a second region (121), a third region (131), and a fourth region (141). The second region (121) is provided between the first region (111) and the third region (131), and the fourth region (141) is provided between the first region (111) and the second region (121). An arithmetic mean roughness (Ra3) of the third region (131) is smaller than an arithmetic mean roughness (Ra2) of the second region (121). An arithmetic mean roughness (Ra4) of the fourth region (141) is smaller than the arithmetic mean roughness (Ra2) and larger than an arithmetic mean roughness (Ra1) of the first region (111).
