Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color ink jet recording method and apparatus, and more particularly to a real black recording method for recording black, referred to as composite black, from three color recording liquids of yellow, magenta and cyan by superimposing the recording liquid. The present invention relates to a color ink jet recording method and apparatus capable of easily realizing a color closer to the original black color derived from a black recording liquid referred to as “color ink”.

[0002]

2. Description of the Related Art In a conventional color ink jet recording apparatus, recording is performed using recording liquids of four colors of yellow, magenta, cyan, and black in order to realize a more blackish black, so-called real black. But,
Such a recording apparatus has disadvantages in that the apparatus cost is increased and the scale of the apparatus is increased.

Therefore, recently, for cost reduction and downsizing, three colors of yellow, magenta and cyan have been developed.
There are many commercially available models in which a head equipped with only a color recording liquid (color recording liquid) is used exclusively, and a black recording liquid head is optional. In this type of color ink jet recording apparatus, as is well known, black recording called composite black is performed by superimposing the recording liquids of three colors of yellow, magenta and cyan. The recording liquids of the three colors are designed so as to be superimposed and recorded in a predetermined order by a recording apparatus in which the recording liquid is used, in order to bring out black that is closer to black. It should be noted that even when the above-described apparatus using four colors of recording liquid is used for recording a color image or the like, composite black may be used to realize high-quality recording.

[0004]

However, in the case of a composite black formed by superimposing recording of three colors of yellow, magenta and cyan in a predetermined order according to a conventional color ink jet recording method, the color tone of the composite black is real black. There are significant problems such as being far from the recording medium, insufficient recording density, or when various recording media are used, the color tone changes for each recording medium.

[0005] By the way, not limited to the ink jet system,
For example, in various image forming methods such as an electrophotographic method, recording materials of a plurality of colors are superimposed and recorded to express black (composite black). It is also known that in this conventional overlay printing, the color tone of the resulting composite black can be changed depending on the order in which the printing materials of the respective colors are overlaid. On the other hand, for example, it has been attempted to reproduce a composite black having the same color tone in any recording by always keeping the order of recording colors constant.

However, the ink which is a recording material in the ink jet system is a liquid and has a penetrating effect on a recording medium, so that it is extremely difficult to predict a color mixture when a plurality of inks are superposed and recorded. . In addition, since the degree of penetration of the ink varies depending on the recording medium, there is a problem that even when the same recording liquid and the same recording method are used, the obtained color tone greatly varies depending on the recording medium. Particularly, a special recording medium such as an OHP film or a back print film, or a paper having cellulose fibers exposed on the surface, that is, a so-called “plain paper” (in the present specification, the term “plain paper” refers to this kind of paper. ), The change in the color tone of composite black is remarkable between coated paper provided with a coat layer for receiving ink, so-called inkjet dedicated paper.

In consideration of the above-mentioned problems in physical properties, for example, Japanese Patent Application Laid-Open No. 1-127352 discloses that the recording order is reversed between a back print film having a recording surface different from an observation surface and another recording medium. Teach you to However, this recording method is effective only for a recording medium having a recording surface and an observation surface different from each other. For example, a satisfactory effect cannot be obtained with plain paper or paper dedicated to inkjet. Japanese Patent Application Laid-Open No. 62-271778 discloses a special dedicated recording medium such as a back print film.
It discloses that printing is performed in descending order of ink penetration. However, this recording method is effective only for a special dedicated recording medium, and for example, a satisfactory effect cannot be obtained with plain paper or ink jet dedicated paper. Further, in the case of the two recording methods described above, mainly the intermediate colors (red,
(Green, blue, etc.) color reproduction can be improved, and a composite black closer to real black has not yet been formed.

SUMMARY OF THE INVENTION An object of the present invention is to overcome the problems of the prior art as described above, and to provide a composite black closer to real black without being affected by the type of recording medium to be used and the composition of the recording liquid. An object of the present invention is to provide a color ink jet recording method which can be easily formed. Another object of the present invention is to provide a color ink jet recording apparatus useful for performing the above color ink jet recording method.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a color ink jet recording method and apparatus according to the present invention will be described with reference to preferred embodiments. However, it should be understood that the invention is not limited to only these embodiments. As described above, the present invention uses at least the recording liquids of three colors of yellow, magenta, and cyan, and, if necessary, also uses the recording liquids of other colors, such as black, in combination. And a method and apparatus for performing recording on a recording medium by an ink jet method.

In one aspect of the color ink jet recording method according to the present invention, when performing composite black recording by superposition recording of three color recording liquids of yellow, magenta and cyan, the method depends on the type of recording medium used. The order of superimposed recording of yellow, magenta and cyan is changed. In particular, the order of the overprinting is changed for each recording medium having different characteristics, such as a back print film, an OHP film, plain paper, and coated paper (paper dedicated to ink jet).

In particular, when the recording medium is plain paper or coated paper, it is preferable to change the order of the superimposed recording of yellow, magenta and cyan for each recording medium. According to the findings of the present inventors, it is particularly preferable that such a change in the order of the overprinting be performed such that it is reversed. The yellow, magenta, and cyan recording liquids used for composite black recording as described above have a status A density of 0.9 or more when a pattern with a printing rate of 100% is printed on plain paper in a single color. It is preferable to present it. By forming a composite black using a recording liquid exhibiting a status A density of 0.9 or more, the optical reflection density can be made 0.9 or more.

Is preferred.

The color ink jet recording apparatus according to the present invention is an ink cartridge which is filled with recording liquids of at least three colors of yellow, magenta and cyan, and may be further filled with a recording liquid such as black if necessary. And the order of the yellow, magenta, and cyan overprinting according to the recording medium used when performing composite black printing by the overprinting of the three colors of yellow, magenta, and cyan, or the color tone of the printing solution used. And a recording order changing means capable of changing the recording order.

The ink cartridge is provided with a nozzle for ejecting a recording liquid of each color to its recording head.
Here, when the recording method used is a serial method and the recording head is scanned in a direction perpendicular to the transport direction of the recording medium, the nozzle for each color or a head having the same nozzle is set in the same scanning direction as the recording head. It is preferable to arrange them so that Further, when the print head scans, it is preferable to perform printing in one of the forward path and the return path of the scanning.

It is preferable that the recording order changing means is provided with a memory for storing the recording order in a recording device (in particular, also referred to as a "printing device"), and to transfer the data to a printing control unit. Furthermore, in the recording apparatus of the present invention, first, a composite black is formed using all possible combinations of the recording order, and then the user selects the recording order according to the recording medium actually used. It is preferable to provide a means capable of performing the above.

The outline of the preferred embodiment of the present invention has been described above. Subsequently, the color inkjet recording method and apparatus according to the present invention will be described more specifically. Usually, when creating product specifications of a color ink jet recording apparatus, this is done by finding the best combination of yellow, magenta and cyan for forming composite black at the design stage.
However, in practice, the recording media used by the user are diversified as described above, and the degree of ink penetration differs for each medium. Therefore, the formation of composite black is performed in a recording order preset in the product specifications. Does not make it possible to express black that is closest to real black. That is, the present inventors have obtained the knowledge that the printing order in which the highest composite black can be actually formed by superimposing yellow, magenta, and cyan is different from the printing procedure of the product specification, and earnestly obtained. As a result of research, it was impossible to predict at all in the past, but by changing the recording order according to the color tone of the recording medium or recording liquid as in the present invention,
It has been found that a composite black having a higher density and closer to the real black color tone can be formed using only the color recording liquid.

The printing order of the color printing liquid is changed depending on the printing medium. In particular, the present inventors paid attention to changing the printing order between plain paper and coated paper, that is, ink-jet dedicated paper. This is because, as described below, the process of penetrating the recording liquid is greatly different between plain paper and paper dedicated to inkjet. Since the recording material used as the ink is a liquid, when recording is performed using the liquid, a color distribution can be formed in the recording medium in the depth direction. Accordingly, composite black printing was attempted on all commercially available general plain paper and inkjet-only paper using all possible combinations of recording orders. As a result, the color of the ink that was last printed on plain paper and the color of the ink that was printed first on inkjet-only paper greatly affected the color tone of composite black. There was found. From this, even in the recording order of each color ink that can reproduce ideal black on inkjet dedicated paper,
On plain paper, only unsatisfactory black could be reproduced, and it was found that better black could be realized by recording in a different recording order. This is because, on plain paper, since the cellulose fibers communicate from the surface to the inside, the ink recorded on the plain paper surface penetrates in the depth direction one after another, and is recorded later. This is considered to be because the ink that has been removed easily remains on the surface.
Conversely, ink-only paper has a coating layer on its surface for receiving ink, so that the ink recorded on the surface first stays in the ink receiving layer most without penetrating inside. It is considered possible.

In plain paper recording, yellow,
It has been found that the yellow color tone is very important among the three colors of magenta and cyan. When the yellow value a ^* in the L ^* a ^* b ^* space of the CIEL ^* a ^* b ^* color system is positive, the resulting composite black color tone is bright yellow (reddish yellow), and On the other hand, when a ^* is negative, the resulting color tone is lemon (bluish yellow). Therefore, when the value a ^{* of} yellow is positive, the recording of cyan, which is a bluish element, is recorded at the last stage having the greatest influence.
Black can be reproduced more realistically.

Changing the printing order as described above means that the printing head mounted on the printing apparatus is scanned in a direction perpendicular to the direction of transport of the printing medium, that is, a so-called serial type color inkjet printing. Case 1
It is desirable that the nozzle 2 for each recording liquid or the recording head 1 having the same is in the same direction as the scanning direction A of the head 1 as shown in FIG. In the drawing, C is a head for cyan recording liquid, M is a head for magenta recording liquid, Y is a head for yellow recording, and B is a conveying direction of the recording medium. The reason why the arrangement of the recording head 1 is desirably the same as the scanning direction A of the head is that, in the case of the serial system, the arrangement of the nozzles or the head having the nozzle is perpendicular to the scanning direction of the head, and If the transport direction is only the forward direction (one direction), the recording order is physically determined.

FIG. 2 is a perspective view showing a preferred embodiment of the ink jet recording apparatus according to the present invention. In the illustrated device, the recording medium 5 conveyed in the direction of arrow B is
At a predetermined recording site, the recording head 1 attached to the front surface of the ink cartridge 3 can scan in the direction of arrow A. Here, if the arrangement of the recording heads for each color is arranged perpendicular to the scanning direction of the heads as described with reference to FIG. 1, the recording of each color must be performed in the transporting order of the recording medium. If the recording medium transport procedure is bidirectional, it is possible to change the recording order, but it is clear that not only the transport procedure becomes complicated, but also high precision is required for the positioning of the recording medium at that time. Required.

Also, since there is a clear difference in the degree of penetration of the ink penetrating into the recording medium between plain paper and ink jet-only paper, the recording order for these recording media is set in reverse, and If printing is performed only in one direction of the head scan direction, ie, forward or backward, not only the printing order can be easily changed, but also one line can be printed by one scan.

Next, as a result of a subjective evaluation and a survey of ink jet recording apparatuses made by other companies, the black recording density was determined as follows.
In the ink jet system, the optical reflection density on a plain paper (the optical reflection density of a pattern with a printing rate of 100%) is 0.9.
It turned out that it was acceptable if it was above. When a composite black is formed by superimposing and recording three color inks of yellow, magenta, and cyan, as a means for obtaining a recording density of 0.9 or more as described above, a single color status of each color ink is used. It has also been found that the A concentration needs to be 0.9 or higher.

Further, the suitable recording order changing means to be incorporated in the recording apparatus of the present invention is not limited to the one described below, but may have a configuration as shown in FIG. . The illustrated recording device (printing device) has a memory for storing the recording order in the device, and the data can be transferred to the printing control unit of the control unit. The print control unit drives the head in accordance with an instruction from the memory while cooperating with a paper feed control unit also included in the control unit, and can achieve desired printing. The procedure for changing the recording order can be, for example, a procedure as shown in the flowchart of FIG. That is, by allowing the user to select the recording order as shown in the drawing, it is possible to always express better black desired by the user on any recording medium.

In the present invention, if the status A density of a single color of the three colors constituting the composite black is 0.9 or more for all colors on plain paper in the same print pattern,
The optical reflection density of composite black is also 0.1% on plain paper.
9 or more.

[0029]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described with reference to embodiments. In the following embodiment, an example is shown in which recording is performed on a recording medium by using recording liquids of three colors of yellow, magenta, and cyan. However, a recording liquid of black is added to the recording liquids of three colors. Even with a color recording liquid system, it is possible to achieve good composite black by superposing and recording three color recording liquids of yellow, magenta and cyan according to the present invention. Example 1 Three types of inks A, B, and C (three-color inks containing cyan C, magenta M, and yellow Y, respectively) satisfying the following conditions were prepared according to a conventional method.

The value of the color tone a ^* of the condition AY set for the trial ink is negative, and the status A density of a single color is 0.9 or more for all colors on plain paper. The value of the color tone a ^* of BY is positive and the status A density in a single color is 0.9 or more for all colors on plain paper.

C: Status A density of a single color is 0. 0 for M and C on plain paper. 9 or more, less than 0.9 for Y. Further, as recording media, plain paper for copying manufactured by Company X and paper dedicated to inkjet (coated paper) manufactured by Company C were prepared. Set each recording medium in the serial type ink jet printing device (drop-on-demand type, resolution 360 dpi, ink particle amount = about 50 pl), and for each recording medium, set the prototype ink A was used to print composite black. After drying sufficiently, the color tone and optical reflection density of the obtained print were measured with a colorimeter. The results of colorimetry of the resulting composite black are shown in Table 1 below. In the following table and the other tables that follow, for example, CM-
Y indicates that printing was performed in the order of cyan C, magenta M, and yellow Y. Further, a black color tone represented by the following equation (1):

[0032]

(Equation 1)

Is ideally zero (0).

[0034]

[Table 1]

In Table 1 above, for plain paper, MC
Although the black color tone (1) of -Y or CMY has a value closer to 0, the YM-
C and Y-C-M show values closer to zero. That is, from the results described in this table, it can be seen that when printing a composite black that is closer to black, it is preferable to change the recording order between plain paper and inkjet-only paper. Example 2 The procedure described in Example 1 above was repeated. In this example, the prototype ink B prepared above and plain paper (manufactured by Company X) as a recording medium were used. The colorimetric results of the obtained composite black are shown in Table 2 below.

Further, using the prototype inks A and B,
The procedure described in Example 1 was repeated. In this example, however, each color was printed on plain paper (manufactured by Company X) in a single color of yellow, magenta and cyan. Table 3 shows the obtained colorimetric results.

[0037]

[Table 2]

[0038]

[Table 3]

Comparing the results in Table 1 and Table 2 in Example 1, it can be seen that, even with the same plain paper, the recording order YMC, MY- C and MC-
In Y, the value of the black color tone represented by the above equation (1) is smaller. The values of the color tone (1) of YMC and MCY are almost the same, but the value of L ^* is black which is closer to real black since the value of YMC is lower. Can be determined. In the formation of the composite black, the preferable recording order of the prototype ink A of Example 1 is clearly different.

Further, from the results shown in Table 3, although the color tone of magenta and cyan is not so different between the test inks A and B, that of yellow is clearly different. And a ^{* of} yellow is the prototype ink A
Is negative, and the test ink B is positive. From the above results, in plain paper recording, if a ^{* of} yellow is a positive value, recording cyan at the end is the method of expressing the best black tone, and a ^{If *} is a negative value, it can be seen that recording yellow at the end is the best way to express black tones. Example 3 In order to evaluate the recording density, the method described in Examples 1 and 2 was repeated using the prototype ink C. The results of the recording density measurement are shown in Table 4 below. As for the density of the mark, the column of the single color is the status A density and the column of the composite black is the optical reflection density (OD).

[0041]

[Table 4]

The concentration shown in Table 1 of Example 1 was compared with the concentration shown in Table 4 above.
In comparison with the densities shown in the table, in the prototype ink A, the status A density was 0.9 or more for all three colors of yellow, magenta and cyan, and the optical reflection density of the composite black was 0.9 or more. Is shown. On the other hand, in the prototype ink C, two of the three colors have a status A density of 0.
Despite being 9 or more, the optical reflection density of the composite black does not satisfy 0.9. From these measurement results, it can be seen that in order to make the optical reflection density of the composite black 0.9 or more, it is necessary that the recording density of a single color be 0.9 or more for all colors. Other Measurement Results The present inventors conducted a series of printing experiments using the following commercially available recording media, inkjet inks, and prototype inks to evaluate the printing characteristics. Recording media used: Plain paper for copying (manufactured by Company X) Plain paper (letter paper with watermark) Regenerated plain paper for copying (manufactured by Company X) Inkjet paper (manufactured by Company C) Inkjet dedicated paper (manufactured by Company E) Inkjet Exclusive paper (manufactured by K) Ink for ink used: Prototype ink Ink manufactured by C company A Ink manufactured by E company A Ink manufactured by E company
A ^* value is negative, a ^* of Y on plain paper of ink A manufactured by Company C
The value is positive. The obtained results are shown in Tables 5 to 10 below. In the table, VO is the optical reflection density of the composite black, and CO, MO and YO are the status A densities of the monochromatic C, M and Y, respectively.
