Patent ID: 8342629

Claim:
A liquid ejecting apparatus executing a collective multiple liquid ejecting process of ejecting a liquid so as to superimpose the predetermined number of unit images on basic images formed on a target, the liquid ejecting apparatus comprising: an ejection executing unit which ejects the liquid onto the target from an ejecting head; a position acquiring unit which acquires arrangement positions of the predetermined number of two or more basic images, at which an arrangement image in which the predetermined number of two or more unit images are arranged among the plurality of basic images formed on the target is superimposed; an image adjusting unit which detects an error between the acquired arrangement positions of the basic images and arrangement positions of the predetermined number of two or more unit images, and adjusts the arrangement positions of the unit images by allocating the detected error to each unit image; and an ejection controlling unit which controls the ejection executing unit to execute the collective multiple liquid ejecting process of ejecting the liquid by using the unit images of which the arrangement positions are adjusted, so that each arrangement image in which the predetermined number of two or more unit images are arranged is superimposed on the predetermined number of two or more basic images formed on the target; wherein the image adjusting unit determines whether the sizes of the unit images falls in a predetermined allowable range with respect to the size of the basic images on the basis of the detected error, wherein the image adjusting unit changes the unit images on the basis of the acquired sizes of the basic images and adjusts the arrangement positions of the changed unit images when the determination result exceeds the predetermined allowable range, and adjusts the arrangement positions of the unit images without changing the unit images when the determination result falls in the predetermined allowable range, and wherein the ejection executing unit executes the collective multiple liquid ejecting process in the state where the arrangement positions of the unit images are adjusted.
