There is provided an ink set used by being attached to a recording medium together with a reaction liquid which reacts with and aggregates components of an ink composition, the ink set including a first ink composition which includes a coloring material, a fixing resin, and a resin-dissolving solvent, and a second ink composition which includes a coloring material, a fixing resin, and a resin-dissolving solvent and which is the same color ink as the first ink composition.

Ink set and recording method

An ink jet recording method using ink selected from a group including (A) black ink containing black pigment, (B) mixed color black ink containing black and color pigments, and (C) color ink containing color pigment, in which an ink glossiness at 60&#xb0; is increased in the order of black ink (A), mixed color black ink (B), and color ink (C), the target recording surface glossiness at 60&#xb0; in a target recording medium is 40 or more, and at least one of the following is satisfied: (1) A black image is formed using at least a plurality of types of the color ink of (C) and a color image is formed using the color ink of (C), and (2) A black image is formed using the mixed color black ink of (B) and a color image is formed using the color ink of (C).

Ink jet recording method, ink jet recording apparatus, and recorded matter

An ink jet recording method includes a first process in which a coloring ink is recorded on a recording medium using an ink jet head so as to form a first image, a second process in which a background ink is recorded using the ink jet head so as to form a background image that covers the first image, and a third process in which a coloring ink is recorded using the ink jet head so as to form a second image, and a drying process is included between the first process and the third process.

Ink jet recording method and recording apparatus

A liquid discharging apparatus includes upstream side nozzle group, a downstream side nozzle group, and a transport mechanism. The downstream side nozzle group is located on a downstream side in a transport direction as compared with the upstream side nozzle group. The transport mechanism transports a medium in the transport direction to the upstream side nozzle group and to the downstream side nozzle group. The upstream side nozzle group and the downstream side nozzle group each are formed of a plurality of nozzle columns that are arranged in the transport direction. Each of the nozzle columns is formed so that a plurality of nozzles that discharge liquid are arranged in a direction that intersects with the transport direction. A transport speed varies in accordance with the number of nozzle columns used.
