Patent ID: 8029087

Claim:
A droplet ejection apparatus, comprising: a treatment liquid deposition device which deposits treatment liquid aggregating ink onto a medium; an ink droplet ejection device which ejects droplets of ink onto the medium on which the treatment liquid has been deposited; a droplet ejection correction device which corrects a droplet ejection volume of the ink droplet ejection device in accordance with distribution of the treatment liquid on the medium; a medium conveyance device which conveys the medium relatively with respect to the treatment liquid deposition device and the ink droplet ejection device: and a droplet ejection correction region identification device which identifies a droplet ejection correction region in which a deposition volume of the treatment liquid on the medium changes in accordance with variation in a conveyance speed of the medium by the medium conveyance device, wherein the treatment liquid deposition device is an application roller which applies the treatment liquid while making contact with the medium, and wherein the droplet ejection correction device corrects the droplet ejection volume of the ink droplet ejection device onto the droplet ejection correction region identified by the droplet ejection correction region identification device.
