Provided is a recording medium comprising an ink-receiving layer provided on at least one face of a base material, wherein a surface of the ink-receiving has the maximum specular glossiness within a measurement angle range of from 20&#xb0; to 60&#xb0;.

Recording medium and image-forming method employing the same

An ink jet recording apparatus for recording by discharging ink from nozzles of a recording head to a recording medium comprises a figure recording control section for executing recording control of figure draw commands for ruled lines and other figures, and a bitmap recording control section for executing recording control of draw commands other than the figure draw commands by developing bitmaps. For this ink jet recording apparatus, draw commands are individually controlled by the recording control sections, respectively, and at the same time, recording is performed by relatively moving in the intersecting two directions a recording head for discharging ink by the draw commands, and a recording medium held by a recording medium holding unit in the position facing the ink discharge surface of the recording head. With the structure thus arranged, it becomes possible to materialize an ink jet recording apparatus which can output high quality images while neither creating deviating seams of ruled lines to the left or right nor creating black strips or white strips.

Ink jet recording apparatus

An ink-jet recording medium having, on a base material, a porous resin layer containing water-dispersible resin particles B having a minimum film-forming temperature of not lower than 0&deg; C., and water-dispersible resin particles A having a minimum film-forming temperature higher than the film-forming temperature of the water-dispersible resin particles B and having an average particle size larger than the average particle size of the water-dispersible resin particles B.

Ink-jet recording medium

Disclosed herein is a recording medium for ink-jet recording, which comprises at least one first half-cut line formed in a machine direction (MD) and at least one second half-cut line perpendicular to the MD direction, wherein the half-cut lines are in the form of a series of perforations with a cut portion and an uncut portion alternately arranged continuously, and the length of the uncut portion in the first half-cut line is longer than the length of the uncut portion in the second half-cut line.

Recording medium for ink-jet recording

Disclosed herein is a recording medium comprising a base material, an ink-receiving layer containing an alumina hydrate provided on one side of the base material, an adhesive layer provided on the side opposite to the ink-receiving layer of the base material, and a release sheet covering the adhesive layer, wherein the surface of the adhesive layer on the side of the release sheet has such structure that recessed portions and projected portions are regularly repeated, and a recessed and projected surface corresponding to the recessed portions and the projected portions of said surface of the adhesive layer is formed by the release sheet covering the adhesive layer.

Recording medium

Provided is a recording method for image formation on a recording medium by application thereon of an ink containing a water-soluble dye having an anionic group or a cationic group in the molecule: the recording medium comprising a substance having an ionic group counter to the anionic or cationic group of the water-soluble dye and having molecular weight of not higher than 1,000, and a polymeric substance having molecular weight of not lower than 2,000.

Recording medium and ink-jet recording process
