  • Patent number: 10668728
    Abstract: To provide an ink jet recording method capable of, after repeated contact of a porous layer of a liquid absorption member with a first image, suppressing adhesion of a coloring material to the porous layer and a partial loss of a recorded image. Provided is an ink jet recording method for recording an image on a recording medium with a water-based ink containing first and second inks. The method includes applying a coloring material-containing first ink to a first recording medium to form a coloring material layer, applying a second ink not containing a coloring material but containing resin particles onto the coloring material layer to form a resin layer and thereby forming a first image comprised of the coloring material layer and the resin layer; and bringing a porous layer of a liquid absorption member into contact with the first image to absorb a liquid component therefrom.

  • Patent number: 8313188
    Abstract: An ink jet printing apparatus according to the present invention includes a dryer configured to dry ink on a print medium. The dryer includes a heating unit configured to heat air in the dryer, and an outside air adjustment mechanism configured to adjust the amount of outside air introduced into the dryer. When the outside air adjustment mechanism is controlled so that the outside air introduction amount is increased, before the control of the outside air introduction amount, the heating unit is controlled so that heated air heated by the heating unit is preheated to a second target temperature higher than a predetermined first target temperature for a normal operation. Even if the outside air introduction amount is actually increased to temporarily reduce the temperature of heated air, the temperature of the heated air can be maintained at a value required for sufficient drying.
