Problems solved by technology

[0005] However, in the inkjet recording device described in Patent Document 1, since it is necessary to perform correction corresponding to the ink ejection characteristics of each head, it is necessary to provide a drive waveform generation data correction unit for each head, which hinders the cost. reduce such issues
In addition, it is necessary to obtain the correction amount according to the ink ejection characteristics of each head, and there is a problem that it takes time for adjustment.
[0006] In addition, in the recording of characters, lines, etc., there is a problem that an increase in the number of loop operations does not necessarily lead to an improvement in image quality (visibility as characters or line quality of lines).
Specifically, there is a problem that the visibility of characters and the line quality of scribing lines may be reduced due to the dot position shift due to the difference in the moving direction when the head reciprocates during the cyclic operation. such subjects

Embodiment approach 1

[0043] figure 1 It is a front view showing the configuration of a recording system 1 as a "recording device" according to Embodiment 1, figure 2 its block diagram.

[0044] The recording system 1 is constituted by a printer 100 and an image processing apparatus 110 connected to the printer 100 . The printer 100 is an inkjet printer that records a desired image on a long recording medium 5 supplied in a state of being wound into a roll, based on recording data received from the image processing apparatus 110 .

[0045] As the recording medium 5, high-quality paper, cast paper, art paper, coated paper, synthetic paper, etc. can be used, for example. In addition, the recording medium 5 is not limited to this kind of paper, for example, a cloth, a film made of PET (Polyethyleneterephthalate: polyethylene terephthalate), PP (polypropylene: polypropylene), or the like can be used. In addition, in this embodiment, the case where the recording surface of the recording medium 5 is ...

Embodiment 1

[0121] Figure 9 It is a conceptual diagram showing matrix coordinates of halftone data (halftone data 201, halftone data 202) corresponding to the nozzle tips 131 (nozzle tip 1311, nozzle tip 1312) in Example 1, respectively.

[0122] In this embodiment, in order to simplify the description, it is shown that each nozzle tip 131 is configured by passing through eight nozzles. Also, as the simplest example, the matrix coordinates of the halftone data are shown as two halftone processes (the process of generating the halftone data 201 and the process of generating the halftone data 202 ) applied to the same area of ​​the image data. Different examples.

[0123] like Figure 9 As shown, in the first halftone processing corresponding to the nozzle tip 1311, the halftone data is developed in matrix coordinates such that the density in the X-axis direction (main scanning direction) becomes half. Further, in the second halftone processing corresponding to the nozzle tip 1312, the ...

Embodiment 2

[0149] Figure 13 is relative to the recording method representing Example 1 Figure 11 On the other hand, a conceptual diagram of the recording method of the second embodiment is schematically shown.

[0150] In the recording method of the present embodiment, in each predetermined recording region Rn, the directions of the cyclic operations of the nozzle tip 1311 and the nozzle tip 1312 are set to the same direction.

[0151] Figure 14 It is a schematic diagram showing a configuration example and cyclic operation of the recording head 13 that realizes recording in the recording method of the present embodiment by the full-color printer 100 .

[0152] In addition to the black ink nozzle row K, the five nozzle rows 130 (cyan ink nozzle row C, magenta ink nozzle row M, yellow ink nozzle row Y, gray ink nozzle row LK, light cyan ink nozzle row LC) The structure and recording method are the same as those in Example 1. Although the black ink nozzle row K has four nozzle tips 1...

Abstract

The invention provides a recording device, an image processing apparatus, and a recording method. The recording device is capable of implementing recording in which the time and effort for adjusting the difference in ejection characteristics of each head are reduced, thereby reducing the influence of point position deviation due to the difference in the direction of movement of the heads. The recording system (1) records a recording image based on image data by repeating a pass operation and a conveying operation, and is characterized in that the recording system includes an assigning section(121) for obtaining a plurality of halftone data which is generated with respect to the same area of the image data based on the image data, and which corresponds to the ink of a predetermined color,and then assigning each of the halftone data obtained to the pass operations in the same direction in reciprocation in the main scanning direction in a predetermined recording area.

Description

technical field [0001] The present invention relates to a recording apparatus that ejects liquid to perform recording, an image processing apparatus that generates recording data for causing the recording apparatus to perform recording, and a recording method that ejects liquid to perform recording. Background technique [0002] A serial inkjet printer alternately repeats the following cycle operation and conveyance operation to form dots (dot arrays) arranged in the main scanning direction so as to be arranged along the conveyance direction, and to place them on the recording medium. An image is formed, wherein the circulation operation is to eject ink while reciprocating (main scanning) a head on which a nozzle row for ejecting ink droplets is formed in a main scanning direction with respect to a recording medium (printing medium). The dripping operation is an operation of moving the recording medium (sub-scanning) in a conveying direction (sub-scanning direction) intersec...
