- FIG. 3 shows printing of a high-density red solid image in one pass using the recording element substrate 100 of the present invention (all nozzles in Y1, Y2, and M1 nozzle rows, carriage scanning direction recording density: 600 dpi / 75%.
- the state of the ejection surface immediately after repeating (duty) is shown. Although a large amount of ink mist was observed between M1 and Y1, it was confirmed that normal printing could be performed without any discharge for all nozzles even immediately after printing on the entire surface of A4 size paper.
- the mechanism by which the discharge failure occurs due to the mist adhering to the discharge surface described in the background art is considered as follows. First, as described above, when high-density printing of a secondary color is performed using a head in which nozzles are arranged at high density, ink mist adheres to the discharge port surface. This continues constantly during the recording scan, and at the same time, ink mist accumulates on the ejection port surface and combines with each other to create a larger ink reservoir. When the ink pool further expands and reaches the vicinity of the opening edge of the discharge port, the ink on the discharge port surface enters the nozzle from the discharge port (refer to FIG. 4 hereinafter).
- the ink that has entered the nozzle continues to evaporate from the time it is ejected until it has entered the nozzle. Therefore, the viscosity is higher than that of the ink held in the nozzle.
- the resistance in the front portion of the heater 105 (in the discharge port direction) is higher than usual. For this reason, even if the ink cannot be ejected or even if it can be ejected, the ejection direction may be distorted or the ejection speed may be reduced.
- the viscosity of the thickened ink that has entered the nozzle from the discharge port is gradually reduced as the water is supplied (diffused) from the supply port 104 side as time passes. That is, when this moisture diffusion is performed instantaneously, normal ejection can be performed immediately, so that there is almost no adverse effect on actual printing. When it takes time to diffuse the moisture, the ink viscosity in the forward direction of the heater 105 is maintained high for a while, and there is a case where normal ejection cannot be continued.
- the Q of the nozzle rows of C1, M1, Y1, and Y2 that discharge relatively large droplets is about 45.9.
- the Q of C2 and M2 that eject relatively small droplets is about 22.5
- the Q of C3 and M3 that ejects the smallest droplet is about 11.2. That is, the magnitude relationship of Q of each nozzle row is a relationship of C1, M1, Y1, Y2> C2, and M2> C3, M3.
- a nozzle having a small Q value is located outside the region between nozzle rows that eject large droplets when forming a secondary color, that is, outside the region where ink mist tends to adhere to the ejection port surface. Is arranged.
- the nozzle rows of M2 and M3 having a small Q value are arranged outside the region between the nozzle rows of Y1, Y2, and M1.
- the M3 nozzle row having the smallest Q value is arranged at a position farthest from the above region.
- the average cross-sectional area in the direction orthogonal to the ink supply direction is A
- the length in the ink supply direction is L.
- the nozzle row having the smallest value of A / L is disposed outside the region while the nozzle rows having the largest discharge amount are arranged in parallel.
- the nozzle row having the smallest value of A / L is arranged at the ends of the plurality of nozzle rows in the direction intersecting with the nozzle row.
- the head having this nozzle configuration can eject black ink, it can output a recorded image having a higher contrast than the case of only three basic colors (cyan, magenta, and yellow). Further, by arranging the positions of the black nozzle rows outside the three basic colors, the influence of the thickened ink attached to the ejection port surface when forming the secondary color described in the first embodiment is reduced. be able to.
- the black nozzles K1 and K2 have a discharge amount of about 5 pl and the Q is the same value as the cyan, magenta, and yellow nozzles C1, M1, Y1, and Y2.
- this black ink is used as an auxiliary color, and is not mainly used for a high-density solid image of the secondary color unlike the other three basic colors, and is ejected at a high density and a high frequency. There is nothing. Therefore, even if the nozzle rows of K1 and K2 and the nozzle rows of other colors (M1 row in this embodiment) are ejected simultaneously, strong airflow vortices toward the face surface do not occur, and ink mist on the ejection surface The adhesion of is very slight. Therefore, there is no problem even if a nozzle having a small Q value such as the M2 row or the M3 row is arranged between the K1, K2 row and the M1 row.
- the small nozzles (M3, C3) and the middle nozzle row (M2, C2) are arranged on the same side with respect to the supply port 104 with respect to the magenta and cyan nozzle rows, but the present invention is not limited to this.
- the large nozzle row (M1, C1) and the middle nozzle row (M2, C2) are arranged on the same side with respect to the supply port, and the small nozzle row (M3, C3) on the other side. ) May be arranged.
- at least nozzle rows that are susceptible to thickening ink may be arranged outside the region between the large nozzle rows.
- a nozzle row that ejects gray ink may be used instead of a nozzle row that ejects black ink, or a gray nozzle row may be present in addition to the black nozzle row.
- the nozzle rows are arranged in the order of magenta, cyan, and yellow in the direction orthogonal to the nozzle rows.
- the color arrangement order is limited to this as long as the above-described Q relationship is satisfied. It is not a thing.
- the nozzle row that ejects three types of droplets, large droplets, medium droplets, and small droplets, has been described. It may be an inkjet head composed of nozzle rows.
- the present invention is used in an inkjet head mounted on an inkjet printer that performs recording by ejecting ink such as ink toward a recording medium such as paper.
Abstract
Description
図5は本発明が用いられる記録装置の構造を説明する概略図である。プリンタ本体は、筐体1、一定方向に往復捜査するキャリッジ3、記録紙4を供給する給紙機構2、画像の記録を行った記録紙4を排出する排紙機構(図示せず)などを備える。
Q=(A1/L1)+(A2/L2)+(A3/L3)・・・[式1]
とすると、Qの値が大きいほど、増粘インクが侵入することによる悪影響を受けにくい。逆にいうと、Qの値が小さいほど増粘インクの浸入に対して弱いノズルであるといえる。つまり断面積が小さいほど、また経路の長さが長いほど上述したインクの低粘度化が遅くなるためである。
