Definitions

  • the present invention relates to an image recording medium on which information relating to a recording medium is recorded, and an ink jet recording apparatus having means for ejecting an ink to the image recording medium to record an image, and writing and reading information to and from the image recording medium.
  • dots are formed by ejecting minute ink droplets and attaching them to a recording medium such as paper to record images and characters. Since it has low noise, does not require processes such as development and fixing, and can easily perform full-color recording, it has rapidly spread to various fields such as various printers, facsimiles, and computer terminals.
  • ink jet recording apparatuses employing the ink jet recording method such as higher speed, higher definition, and higher image quality full color, have been spurred by higher performance.
  • a wide variety of recording media have been used. Therefore, an inkjet recording apparatus that can perform recording on these various types of recording media under optimal conditions has been required.
  • the characteristics of a recording medium required for high-quality recording include the maximum ink absorption amount of the recording medium, ink absorption speed, ink drying time, ink dot diameter, etc. Of ink absorption characteristics.
  • the maximum amount of ink absorption is a parameter required when controlling the amount of ink ejected per unit area onto the recording medium. If the ink is ejected to the recording medium in an amount equal to or greater than the maximum ink absorption amount, the ink amount becomes excessive and ink overflows from the surface, causing a phenomenon of blurring. Conversely, if an image is formed with a small ink amount relative to the ink absorption amount, there arises a problem that the image density is reduced and the image quality is reduced. Therefore, it is necessary to appropriately control the ink ejection amount per unit area with respect to the ink absorption amount.
  • the ink absorption speed is a parameter required when controlling the amount of ink ejected per unit time for ejecting the recording medium. If printing is performed at a speed higher than the ink absorption speed, the next ink droplet will be ejected before the first ink droplet is absorbed by the recording medium. In this case, the ink droplets are merged. The problem is that large ink droplets are formed and are joined to adjacent ink dots. Therefore, it is necessary to appropriately control the amount of ink ejected per unit time with respect to the ink absorption speed of the recording medium.
  • the ink drying time is a parameter required when controlling the printing interval time during continuous printing. If printing is performed at a fast pace shorter than the ink drying time, the next image is output before the ink on the printing surface of the printing medium is completely dried, and ink is printed between the printing media horizontally placed on the output tray. However, there is a problem that the image is transferred or the image is disturbed by rubbing. Therefore, it is necessary to appropriately control the recording interval time with respect to the ink drying time of the recording medium.
  • the ink dot diameter is a parameter required for controlling an ink ejection amount per unit area ejected to a recording medium.
  • Unit area The amount of the ejected ink per hit is determined by the volume of the ejected ink droplet and the set resolution.
  • the volume of the ink droplet is larger than necessary or when the resolution is set higher than necessary, adjacent ink dots are joined to each other, which causes a problem of deterioration in image quality.
  • the volume of the ink droplets is too small, the image density will be reduced and the image quality will be impaired. Therefore, it is necessary to appropriately control the ink ejection amount per unit area (the volume of the ejected ink droplet and the set resolution) with respect to the ink dot diameter.
  • the ink used in the ink jet recording apparatus is roughly classified into a dye ink and a pigment ink.
  • Dye ink is soluble in solvent and shows high purity and vivid color Also, since there is no particle property, scattered light and reflected light are not generated, so the transparency is high and the hue is clear.On the other hand, if the dye molecules are destroyed by photochemical reaction, the number of molecules will decrease. However, there is a problem that light fastness is poor because it directly affects the coloring density.
  • pigment inks are insoluble in solvents, and dye molecules form particles and contribute to coloring in the state of being dispersed in the solvent.Even if the surface molecules are broken by photochemical reactions, etc. However, since there is a new dye molecule layer underneath, there is an advantage that the decrease in apparent coloring power is small and the image storability is superior to that of dye ink.
  • pigment ink has a problem of poor gloss due to the effects of scattered light and reflected light caused by particles.
  • the surface layer is used to impart gloss to the surface of the recording medium on which an image has been formed using a pigment ink containing a dispersant, to prevent bleeding of the image due to contact with water, and to improve scratch resistance.
  • An image is recorded and formed using a recording medium having an ink receiving layer containing thermoplastic resin particles on the (image recording surface side) and a pigment ink solvent absorbing layer adjacent to the inside of the ink receiving layer, and then heating the recording medium.
  • thermoplastic resin particles in the above-mentioned ink-receiving layer are melted and smoothed by applying pressure to make the ink-receiving layer transparent (Japanese Patent Application No. 2000-1646486). No.)
  • a recording medium on which an image is recorded by a recording head is conveyed to a heating and pressurizing unit by a conveying unit to make the ink receiving layer transparent, and is heated and pressurized to make the ink receiving layer transparent.
