no. 1 approach

[0086] Before describing the first embodiment, a comparative example will be described.

no. 2 approach

[0114] Print data of the second embodiment

[0115] In the first embodiment, the common image portion in one frame is coated (OP), but the variable image portion is not coated. However, it is sometimes desirable to coat the variable image portion (when the variable image portion such as a barcode is more important than the common image portion, etc.). Therefore, in the second embodiment, it is set to coat the variable image portion in the common image portion and the variable image portion.

[0116] Figure 14 This is a diagram showing print data for one frame in the second embodiment. In the second embodiment, as in the first embodiment, an image of one frame is composed of two plates of data. In the second embodiment, such as Figure 14 As shown, the printing data of the first edition (printing data PD21) and the printing data of the second edition (printing data PD22) constitute an image for one frame.

[0117] The printing data PD21 is data for printing the variable image port...

Abstract

A liquid discharging apparatus includes a liquid discharging section which performs a liquid discharging operation for discharging liquid; and a controller which makes the liquid discharging section perform the liquid discharging operation, thereby executing image formation coating processing which forms a plurality of images on a medium and also performs coating of the images, wherein the controller divides and executes the image formation coating processing into first processing of forming a common image portion that is an image site common to each of the plurality of images by making the liquid discharging operation be performed and second processing of performing coating of the common image portion while forming a variable image portion that is an image site which differs in each of the plurality of images, by making the liquid discharging operation be performed.

Description

Technical field [0001] The invention relates to a liquid ejection device. Background technique [0002] As a liquid ejection device, an inkjet printer is known, which ejects ink as a liquid to a medium (for example, paper) to print an image on the medium. As such a printer, a device that prints pictures, graphics, symbols (characters), bar codes, and the like on labels is also known (for example, refer to Patent Document 1). In addition, in such printers, the same printing area (page) of the medium may be repeatedly printed. For example, after forming an image using color inks, a colorless and transparent ink (colorless ink) may be applied to the image to coat the surface of the image. [0003] However, in the label printing and the like described above, a plurality of images may be printed on one printing surface (page), and may include: common parts (common image portions) in the plurality of images, and Different parts (variable image parts) in multiple images. When printing...
