摘要： An ink-jet recording apparatus and an ink-jet recording method which provide an image featuring reduced graininess and good gradation. A plurality of inks of different densities are used to obtain a halftone image with controlled graininess. An ink which has low penetrability on a recording medium and which controls the diffusion of dots is used as an ink with a relatively high density. An ink which has high penetrability and which permits easy diffusion of dots is used as an ink with a relatively low density. The present invention also provides a characteristic recorded article to be formed by a plurality of dots having different penetrabilities on a recording medium. Among a plurality of inks with different densities, the inks of the same color category are grouped and held in an ink container and are divided in the container by the ink density. This configuration makes it possible to make the containers smaller and minimize the number of containers.

摘要： Disclosed herein is a recording medium comprising a base material, the surface of which is coated with a composition comprising, as an essential component, a polymer having a weight average molecular weight of not less than 20,000 which is obtained by reacting a polyvalent carboxylic acid, or anhydride or lower alkyl ester thereof with a polyhydroxyl compound having a weight average molecular weight of not less than 1,000 obtained by adding ethylene oxide and/or propylene oxide to a compound having 2 to 4 active hydrogen atoms.

摘要： A mounted thermal head is energized to determine a thermal change state of the thermal head and a driving condition of the mounted thermal head is set in accordance with the determined thermal change state. The drive condition of the recording head can be self-set at a high precision with a simple construction and stabilization of the recording characteristics and a long lifetime are attained.
