A recording head is operable to eject ink toward a recording medium. A carriage mounting the recording head is operable to carry the recording head in a first direction. At least one infrared ray heater is provided on the carriage so as to oppose the recording medium. An input energy of the infrared ray heater is 60 W or less.
摘要:
An ink composition for ink jet recording is provided. The ink composition includes at least a colorant, water, a poor water-soluble both-end-type alkanediol, a crystalline sugar alcohol that is solid at 20° C., and a poly(alkylene glycol). The poor water-soluble both-end-type alkanediol includes one or two alkyl substituents on its main chain having two hydroxyl groups.

A cap member according to a first aspect of the invention is a cap member that covers a nozzle area of an ejecting head having a plurality of nozzle openings for ejecting fluid. The cap member includes a cap member body having a bottom portion and a frame portion and an absorbing member being fixed to the bottom portion for absorbing the fluid. The bottom portion is arranged so as to oppose the nozzle area, and the frame portion is provided on a peripheral edge of the bottom portion and coming into contact with the ejecting head. An inner peripheral portion extending along the inner surface of the frame portion is a groove portion, and the height of the groove portion from the bottom portion is lower than the upper surface of the absorbing member over the entire circumference of the frame portion.
摘要:
Provided is an ink composition containing a pigment, an aqueous medium, a copolymer resin of a hydrophobic monomer and a hydrophilic monomer, and a urethane resin, wherein the weight ratio of the copolymer resin to the urethane resin (copolymer resin/urethane resin) being from 1/2 to 2/1, and wherein the pigment having an area average particle diameter of from 150 to 350 nm. Also disclosed are a production process of the ink composition, an ink set and a recording process using the ink composition, and a recorded image formed by the recording process.
摘要:
An ink composition that can be prevented from aggregating, form an image free from white streaks and harshness even in low-resolution printing, achieve high dissolution of clogging and high-temperature storage stability, and form a high-quality image, particularly an image having excellent hue is provided.An ink composition that contains at least a pigment, water, an alcohol solvent, a dispersant, and a surfactant, in which the alcohol solvent contains a poorly water-soluble alkane diol, a water-soluble 1,2-alkane diol optionally having a branched chain, and a water-soluble 1,3-alkane diol or alkylene glycol optionally having a branched chain, and the dispersant contains an oxyethyl acrylate resin, is used in an ink jet recording method.
摘要:
A clear ink composition includes at least a slightly water-soluble alkanediol, a water-soluble alcohol as a dissolution aid for the slightly water-soluble alkanediol, water, and polymer fine particles, but does not include a colorant. A 10-Hz dynamic surface tension of the ink composition is 26 mN/m or less.
摘要:
There is provided an ink composition that, even on various recording media, especially gloss paper of a printing paper base, can yield an image having excellent gloss, can realize good recovery from clogging and handleability of recorded matter, and, at the same time, can realize excellent ejection stability and color reproduction. The ink composition for ink jet recording comprises at least a colorant, water, an alkanediol, and a surfactant, wherein the alkanediol comprises a water soluble 1,2-alkanediol and a water soluble alkanediol having a hydroxyl group at both ends of its main chain, and the surfactant is a polyorganosiloxane.
