Patent ID: 8814342

Claim:
A fluid ejecting apparatus comprising: a main image nozzle group comprising one or more colored nozzle groups, wherein each colored nozzle group comprises nozzles and is configured to eject fluid of a single color, wherein the main image nozzle group ejects fluid onto a medium to thereby form a main image; a background image nozzle group comprising nozzles, wherein the background image nozzle group ejects fluid onto the medium to thereby form a background image, wherein the background image comprises a first portion that does not overlap the main image, and a second portion that overlaps the main image; and a control portion which performs a dot forming operation which forms an image by ejecting fluid from the nozzles onto the medium to form dots; wherein, in the dot forming operation, the control portion performs control which makes a first number of nozzles per unit area of the medium of the background image nozzle group used for forming of the first portion of the background image greater than a second number of nozzles per unit area of the medium of the background image nozzle group used for forming of the second portion of the background image, such that the fluid of the first portion of the background image has a higher concentration per unit area of the medium than the fluid of the second portion of the background image.
