A printing apparatus for printing using an inkjet scheme, the apparatus comprising: a plurality of inkjet heads ( 12y to k) that eject ink droplets of a first-color ink of a first color for which at least one color is selected, wherein the plurality of inkjet heads respectively eject ink droplets of different concentrations of the first-color ink, and wherein at least one of the plurality of inkjet heads ejects ink droplets of a resin dispersed ink dispersing particles of a colored binder resin as a dispersoid in a dispersion medium; wherein the plurality of inkjet heads include: a first inkjet head that ejects ink droplets of a first resin-dispersed ink containing particles of the binder resin colored in the first color of a first concentration; and a second inkjet head that ejects ink droplets of a second resin-dispersed ink containing particles of the binder resin colored in the first color of a second concentration lower than the first concentration, characterized in that the binder resin particles in the first resin-dispersed ink and in the second resin-dispersed ink are colored by the same pigment encapsulated in the binder resin particles; the content ratio of the pigment encapsulated in the binder resin particles is made smaller in the second resin-dispersed ink than in the first resin-dispersed ink to color the binder resin particles of the second resin-dispersed ink with the first color of the second concentration lower than the first concentration; and the second resin-dispersed ink and the first resin-dispersed ink contain the binder resin particles in the same content ratio. the apparatus comprising: a plurality of inkjet heads ( 12y to k) that eject ink droplets of a first-color ink of a first color for which at least one color is selected, wherein the plurality of inkjet heads respectively eject ink droplets of different concentrations of the first-color ink, and wherein at least one of the plurality of inkjet heads ejects ink droplets of a resin dispersed ink dispersing particles of a colored binder resin as a dispersoid in a dispersion medium; wherein the plurality of inkjet heads include: a first inkjet head that ejects ink droplets of a first resin-dispersed ink containing particles of the binder resin colored in the first color of a first concentration; and a second inkjet head that ejects ink droplets of a second resin-dispersed ink containing particles of the binder resin colored in the first color of a second concentration lower than the first concentration, characterized in that a plurality of inkjet heads ( 12y to k) that eject ink droplets of a first-color ink of a first color for which at least one color is selected, wherein the plurality of inkjet heads respectively eject ink droplets of different concentrations of the first-color ink, and wherein at least one of the plurality of inkjet heads ejects ink droplets of a resin dispersed ink dispersing particles of a colored binder resin as a dispersoid in a dispersion medium; wherein the plurality of inkjet heads include: a first inkjet head that ejects ink droplets of a first resin-dispersed ink containing particles of the binder resin colored in the first color of a first concentration; and a second inkjet head that ejects ink droplets of a second resin-dispersed ink containing particles of the binder resin colored in the first color of a second concentration lower than the first concentration, characterized in that a first inkjet head that ejects ink droplets of a first resin-dispersed ink containing particles of the binder resin colored in the first color of a first concentration; and a second inkjet head that ejects ink droplets of a second resin-dispersed ink containing particles of the binder resin colored in the first color of a second concentration lower than the first concentration, characterized in that the binder resin particles in the first resin-dispersed ink and in the second resin-dispersed ink are colored by the same pigment encapsulated in the binder resin particles; the content ratio of the pigment encapsulated in the binder resin particles is made smaller in the second resin-dispersed ink than in the first resin-dispersed ink to color the binder resin particles of the second resin-dispersed ink with the first color of the second concentration lower than the first concentration; and the second resin-dispersed ink and the first resin-dispersed ink contain the binder resin particles in the same content ratio.
