Embodiment approach

[0109] In the above-mentioned embodiment, the printer 1 has been described as the liquid ejection device, but it is not limited to this, and it can be embodied as ejection and ejection of other fluids (liquid, liquid body in which particles of functional materials are dispersed, etc.) other than ink. A fluid ejection device such as a gel). For example, in color filter manufacturing equipment, dyeing equipment, microfabrication equipment, semiconductor manufacturing equipment, surface processing equipment, three-dimensional modeling machines, gas vaporization equipment, organic EL manufacturing equipment (especially polymer EL manufacturing equipment), display manufacturing equipment The same technique as that of the above-mentioned embodiment can be applied to various devices to which inkjet technology is applied, such as a film forming device and a DNA chip manufacturing device. In addition, the method or manufacturing method of the above-mentioned device also belongs to the ...

Abstract

A printing device and a printing method. The printing device that forms a background by a first ink and images on the background by a second ink includes a head having first and second nozzle lines that eject, respectively, the first and second inks. The inks are ejected as the head moves, with respect to a medium, in a main scanning direction intersecting the first and second nozzle lines. A transport section transports the medium in a sub-scanning direction along the first and second nozzle lines. In an ejecting operation, the first and second inks are ejected in the relative movement in the main scanning direction and the relative transportation is performed. In the ejecting operation, more nozzles are used in the second nozzle line than in the first nozzle line, and more ejections areperformed from the second nozzle line than from the first nozzle line, thereby filling a predetermined width in the sub-scanning direction.

Description

technical field [0001] The invention relates to a printing device and a printing method. Background technique [0002] There is known an inkjet printing device that ejects ink onto a medium to perform printing. Furthermore, it discloses a printing device that prints a background image and prints an actual image on the background image. In the printing device disclosed in Patent Document 1, overcoat nozzles (white) 312 and color nozzles 21 are arranged separately in the transport direction. The printing device described in Patent Document 2 has a real image head and a background image head. [0003] [Patent Document 1] Japanese Patent Laid-Open No. 2001-239660 [0004] [Patent Document 2] Japanese Patent Laid-Open No. 2003-285422 [0005] If an image is formed after the background is formed, since the image is formed before the ink of the background is dry, the ink of the background may mix with the ink of the image to degrade the quality of the formed image.
