Problems solved by technology

However, forming nozzles with a high degree of integration not only requires high manufacturing technology, but also may lead to a higher frequency of defective products
Therefore, the manufacture of the recording head itself, in which the nozzles are highly integrated, is likely to become one of the factors that increase the production cost.

Embodiment 1

[0148] An example of a recording head in which a 1-color 4-column structure is set for cyan and magenta and a 1-color 2-column structure is set for the remaining colors will be described.

[0149] Figure 10 It is a schematic diagram showing the arrangement of discharge ports for each color ink in the color ink unit 1100 .

[0150] The color ink recording unit of the present invention is provided with a plurality of discharge ports and heaters for generating heat used to discharge ink from the respective discharge ports for the inks of cyan, magenta, and yellow and the second black ink. Wait. Also, two discharge port rows are provided for each color ink. The configuration of the two discharge port rows is symmetrical as above for the cyan, magenta, and yellow inks. For the second black ink, such a configuration is not adopted, and it is set at the discharge port of the yellow ink. Between the row y2 and the row m2 of discharge ports for magenta ink, the discharge port rows ...

Embodiment 2

[0195] In Example 1 ( Figure 10 ) in the recording head structure, the nozzles of the nozzle rows c3, c4, m3, and m4 are set as small-diameter nozzles forming small dots, but the present invention can be realized even with large-diameter nozzles forming large dots.

[0196] Figure 17 An example of a recording head in which the nozzle diameter is set to be the same regardless of the nozzle row is shown.

[0197] exist Figure 17 , a detailed nozzle column description with Figure 10 are roughly the same and are therefore omitted.

[0198] Here, as also described in Embodiment 1, it is explained that it is desirable to arrange nozzles with a displacement of 1 / 4 of the nozzle pitch between the nozzle row groups c1, c2 and the nozzle row groups c3, c4. Figure 10 or Figure 17 The adjacent nozzle columns c1 and c3, or c2 and c4 are arranged with a 1 / 4 nozzle pitch offset. The effect of satisfying this relationship between adjacent nozzle rows will be specifically described...

Abstract

This invention provides a printing apparatus which employs a print head constructed to minimize a memory area to hold ejection data and not requiring a sophisticated manufacturing technology and thusrealizes a print mode to perform a higher-than-normal-resolution printing, making it possible to form a high quality image when needed. For each of cyan and magenta that make large contributions to the formation of an image, four nozzle arrays are allocated. For each of the remaining colors, two nozzle arrays are allocated. For cyan and magenta, the interval between adjoining nozzles of the pairedtwo arrays is set to 1 / 4 the nozzle pitch. For cyan and magenta, all of the four nozzle arrays are used in the high resolution print mode and, in the normal print mode, only two of the four nozzlearrays are used for printing. Of the paired adjoining nozzle arrays, only one is used.

Description

technical field [0001] The present invention relates to a recording device and a recording method using the same, and more particularly, to a recording device and a recording method for recording using a recording head that controls the number of rows of recording elements and the number of recording elements according to the discharged colorant. It is composed of a plurality of recording elements with different intervals. Background technique [0002] In recent years, with the popularization of personal computers, word processors, facsimile machines, etc. in offices and homes, recording devices of various recording methods have been provided as information output devices of these devices. Among them, recording devices such as inkjet printers are relatively easy to adapt to color recording using a plurality of types of inks. In addition, it has various advantages such as low noise during operation, high-quality image formation on various recording media, and small size. Th...
