A liquid ejecting apparatus executes 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 includes: 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.

Liquid ejecting apparatus and controlling method of the same

A data acquisition portionacquires any one of the composition data from a frame card in a case where the identifier of the whole file represents composition data and acquires image data from a memory card in a case where the identifier of the whole file represents the attributes of image data. A control portionretrieves from ROM each parameter corresponding to the identifier of the composition data acquired from the frame card. With the parameters, the control portiongenerates printing data by combining the image data acquired from the memory card with the composition data.

Printer and printing method

An ink jet recording head, in which a vibrating element includes electrodes disposed on both surfaces of at least one of its edge portions at a dot forming pitch. A gap forming member is disposed so as to form a gap suitable for producing ink mist on a surface confronting a vibrating surface of the vibrating element. Since the ink is retained in this gap by surface tension, upon application of an alternate voltage to the vibrating element to produce an edge-mode vibration, the vibration produced at a piezoelectric body substrate is transmitted to the ink, propagating through the ink. The vibration propagated up to an interface between the ink and the air is transformed into a surface wave, thereby misting the ink. The thus produced ink mist, having vibrational kinetic energy, splashes in the air and thus forms a dot on a recording sheet. Since the amount of ink adhering to the recording sheet is proportional to an ink mist producing time, the optical density of a dot can be adjusted by controlling the alternate voltage application time.

Ink jet recording head

In a nozzleless ink jet printer, a plate-shaped propagation element for propagating a surface acoustic wave is fixedly mounted on a substrate which is arranged along the platen and has an ink pooling groove, and the ink led to the edge of the propagation element from the ink pooling groove by surface tension is caused to jet in the form of ink mist by surface acoustic waves generated by excitation of comb-shaped interleaved electrodes so as to record images such as characters and patterns on a recording sheet.
