  • Patent number: 10857784
    Abstract: Reaction liquid application S1 to an ink receiving medium, formation of a first image by ink application S2, liquid absorption S3 from the first image by a porous body of a liquid absorbing member, cleaning S4 of the porous body, and liquid collection S5 from the porous body are repeated in an inkjet printing method. When the porous body comes into contact with the first image, first chemical species in the reaction liquid contributing to increasing the ink viscosity is contained, on the ink receiving medium and in the porous body, at a higher level in terms of molar equivalent per unit area than second chemical species in the ink also contributing to increasing the ink viscosity. In the liquid collection S5, the liquid is collected so that the liquid remains in the porous body on the side to be brought into contact with the first image.

  • Publication number: 20190009515
    Abstract: In a printing apparatus, an image is formed by an inkjet printhead, and a liquid component is absorbed from the image by bringing a cyclically movable liquid absorbing member into contact with the image. Then, the member is nipped by the first roller that contacts the first surface of the member, and the second roller that has a vertical positional relationship with respect to the first roller and contacts the second surface on a side opposite to the first surface. Furthermore, a region where the member is pressurized is formed by sealing the member by bending and winding the member around the first roller located on an upper side of the second roller at the nipped position. Then, the absorbed liquid component is pushed out and collected by moving the member in the nipped state.
