Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an image recording apparatus and an image recording method, and more particularly, to an image recording apparatus and an image recording method for preventing image quality deterioration due to deviation of ink landing positions.
[Prior art]
Conventionally, as a method of recording an image on a recording medium such as paper, an ink jet recording method of discharging ink on the surface of the recording medium and a gravure printing method of transferring ink stored in a concave portion of the plate to the recording medium are often used. Are known. Among these methods, the ink jet recording method can easily and inexpensively form an image, and is therefore applied to various printing fields such as photographs, various printings, special printings such as markings and color filters.
[0002]
By the way, in an image recording apparatus to which the ink jet recording method is applied, the landing position of the ink is deviated due to the deviation of the position and the direction of the nozzle, and even when the same amount of ink is ejected from each nozzle, the image recording direction is not changed. May cause streak-like unevenness, and image quality may deteriorate. In particular, in a line head type image recording apparatus, if there is a deviation in the position of a nozzle or the like, the above-mentioned unevenness occurs remarkably, and the image quality may be significantly deteriorated.
[0003]
Therefore, various methods have been proposed to prevent such image quality deterioration. Specifically, for example, in a line head type image recording apparatus, there is a method of recording an image while avoiding an abnormal portion where nozzle positions are misaligned (for example, see Patent Document 1). In a serial head type image recording apparatus, there is a method of reducing streak-like unevenness by so-called interleaving (for example, see Patent Document 2). Note that interleaving is a method of scanning a location two or more times and ejecting ink from different nozzles to disperse and cause a shift in the landing position of the ink, thereby preventing deterioration in image quality.

[Patent Document 2]
JP-A-5-167838
[0005]
[Problems to be solved by the invention]
However, the method disclosed in Patent Document 1 cannot prevent the image quality from deteriorating when recording is performed on a recording medium having a size in which an abnormal portion cannot be avoided. Further, in the method disclosed in Patent Document 2, since an image is recorded by scanning one location a plurality of times, there is a problem that the time required for image recording becomes long.
Japanese Patent Application Laid-Open No. 2002-127472 describes a method for recording a high-quality image even when a plurality of inks having different physical property values such as permeability into a recording medium and drying properties are used. However, it does not disclose a method for recording a high-quality image when a nozzle position or the like is misaligned.
[0006]
SUMMARY OF THE INVENTION It is an object of the present invention to provide an image recording apparatus and an image recording method that can prevent image quality deterioration due to a shift of an ink landing position.
[0007]
[Means for Solving the Problems]
According to a first aspect of the present invention, there is provided a recording head that discharges ink from a plurality of nozzles toward a recording medium,
An image recording apparatus comprising: a control device that controls the recording head;
The plurality of nozzles are arranged in a direction substantially orthogonal to the image recording direction,
The control device may change an ink ejection amount of a nozzle that causes a deviation of an ink landing position along the substantially orthogonal direction or a nozzle near the nozzle among the plurality of nozzles based on the magnitude of the deviation. It is characterized.
[0008]
Here, the image recording direction is a direction in which the recording head moves when recording an image when the recording head is of a serial head type, and is a direction when the recording head is of a line head type. The direction is opposite to the recording medium conveyance direction.
[0009]
According to the first aspect of the present invention, the control device determines the ink ejection amount of the nozzle that causes a deviation of the ink landing position along the substantially orthogonal direction among the plurality of nozzles or the ink ejection amount of the nozzle near the nozzle by the magnitude of the deviation. Therefore, the amount of ink to be ejected to the area of the recording medium where ink should originally land, that is, pixels, of which the density is increased due to the displacement, is reduced, and It is possible to increase the amount of ink to be ejected to a pixel whose density becomes low due to the displacement. In this way, when the same amount of ink is ejected from each nozzle, almost the same amount of ink can land on each pixel on the recording medium. Can be prevented from occurring. Therefore, even when the position and orientation of the nozzles are displaced in the substantially orthogonal direction due to a manufacturing error or the like, it is possible to prevent the image quality from deteriorating due to the displacement of the ink landing position.
Further, even in an image recording apparatus in which the positions and directions of the nozzles are deviated, high-quality images can be recorded. Therefore, it is necessary to manufacture a recording head in detail so as not to cause a manufacturing error in the positions and directions of the nozzles. Absent. Therefore, the manufacture of the image recording apparatus can be facilitated, and the manufacturing cost can be reduced accordingly.
[0010]
In addition, as a method of changing the ink discharge amount, there are a method of changing the number of droplets to be discharged and a method of changing the amount of ink per droplet. Here, when changing the number of droplets to be ejected, the number of droplets before the change is preferably 5 to 10. The reason why the number of droplets before the change is 5 or more is that if the number of droplets before the change is 4 or less, the gradation of density becomes too coarse if the number of droplets is changed, and a high-quality image is recorded. Because they cannot do it. In addition, the reason why the number of droplets before the change is set to 10 or less is that if the number of droplets before the change is 11 or more, the drive frequency for ejecting ink needs to be increased if the number of droplets is changed. This is because high-speed image recording cannot be performed.
[0011]
According to a second aspect of the present invention, in the image recording apparatus according to the first aspect,
The magnitude of the deviation is measured by detecting an ink landing position corresponding to each nozzle.
[0012]
According to the second aspect of the present invention, the magnitude of the deviation can be measured by, for example, printing a test pattern on a recording medium and detecting each ink landing position.
It is preferable that the amount of the deviation is measured in advance before shipment from the factory or the like, and is stored in the control device as a table associated with each nozzle.
[0013]
According to a third aspect of the present invention, in the image recording apparatus according to the first or second aspect,
The recording head is of a line type.
According to the third aspect of the present invention, since the recording head is of a line type, an image can be recorded at a higher speed than in the case where the recording head is of a serial type.
[0014]
The invention according to claim 4 is the image recording apparatus according to any one of claims 1 to 3,
A light irradiation device that irradiates light to the ink that has landed on the recording medium,
The ink is a photo-curable ink.
[0015]
According to the invention described in claim 4, the ink that has landed on the surface of the recording medium can be immediately cured by the light irradiation device. Therefore, a high-quality image with little blur and blur can be recorded.
[0016]
According to a fifth aspect of the present invention, there is provided an image recording method, wherein the image recording apparatus according to the first to fourth aspects is used.
According to the fifth aspect of the invention, the same effects as those of the first to fourth aspects of the invention can be obtained.
[0017]

Above the platen 5, an image recording device 2 for recording an image is provided. The image recording apparatus 2 includes four recording heads 3 for discharging inks of respective process colors of yellow, magenta, cyan, and black. The recording heads 3 are of a line type and extend along the width direction B of the recording medium K.
[0020]
Here, the recording head 3 will be described in detail with reference to FIG. As shown in this figure, the recording head 3 has a substrate 31, on which a piezoelectric element 32 is provided. A piezoelectric element drive circuit 33 is connected to the piezoelectric element 32 via a lead wire 32a and an electrode 32b. The piezoelectric element 32 expands upward when a pulse signal voltage is applied from the piezoelectric element drive circuit 33.
[0021]
A flow path plate 34 is disposed at a position facing the piezoelectric element 32, and an ink flow path 35 is formed by the piezoelectric element 32 and the flow path plate 34.

Among the nozzles 30a to 30g, the nozzles 30b, 30c, and 30f are in a state in which the direction and the position are shifted in the width direction B of the recording medium K due to a manufacturing error. More specifically, the nozzle 30b ejects 0.2% of the ink to the entire ink ejection amount toward the left side in the figure, and the nozzle 30c ejects 0.3% of the ink to the entire ink ejection amount. The nozzle 30f is ejected toward the right side in the drawing, and the direction and the position are shifted so that the nozzle 30f ejects the ink at a rate of 0.1 to the left side in the drawing. As a result, the nozzles 30a to 30g are not arranged at regular intervals as shown in FIG. 4 (a), but as shown in FIG. 4 (b), the second dot from the left in FIG. Is formed on the right side, and the sixth dot is formed on the left side. Therefore, for example, when five drops of ink are ejected from each of the nozzles 30a to 30g in order to set each density of the pixel to 5, that is, the area of the recording medium where the ink should originally land, the density values of each pixel are equal. Not to be. Such a deviation of the dot position, that is, the deviation of the ink landing position is measured before shipment from the factory by detecting the dot position on the recording medium K on which the test pattern is printed.

The control device controls the irradiation of ultraviolet rays by turning on or off a power supply (not shown) of the ultraviolet irradiation device 4.
The controller controls the temperature of the heater 36b by turning on or off the heater power supply 36c of each of the recording heads 3,. Thereby, the recording heads 3,... And the ink are maintained at a constant temperature within the range of 35 ° C. to 100 ° C., and as a result, the ejection stability of the ink is improved.
[0026]
Further, the control device controls the piezoelectric element driving circuit 33 so as to apply a voltage to a required piezoelectric element 32 of each of the recording heads 3 based on a predetermined image signal. In the present embodiment, for the sake of convenience, an image signal for instructing the control device to eject five drops of ink from each of the nozzles 30a to 30g in order to set the density of each pixel to 5 is input. It shall be.
Further, when controlling the piezoelectric element drive circuit 33, the controller appropriately changes the ink ejection amounts of the nozzles 30a to 30g in order to compensate for the displacement of the dot positions corresponding to the nozzles 30a to 30g in the width direction B. It has become.
[0027]
More specifically, the control device stores a correction coefficient (k) for changing the ink ejection amount of each of the nozzles 30a to 30g as a table in association with the number of the nozzles 30a to 30g, and should be represented. The number of ink droplets corresponding to the calculation result (A × k) obtained by multiplying the density value (A) by the correction coefficient (k) is ejected from each of the nozzles 30a to 30g. Here, when the result of the multiplication is a fraction, the control device performs a process such as rounding up, rounding off, rounding off, etc., to an integer.
Note that the correction coefficient (k) is determined based on the magnitude of the deviation of the dot position in the width direction B of the recording medium K, and more specifically, as shown in FIG. The ink ejection amount of the nozzles 30b, 30c, and 30f corresponding to the pixel whose density value decreases due to the displacement is increased, and the ink ejection amount of the nozzles 30a, 30d, and 30e corresponding to the pixel whose density value increases is decreased. Has been determined. The correction coefficient (k) is determined so as not to change the ink ejection amount of the nozzle 30g corresponding to a pixel whose density is not affected by the deviation of the dot position. Such a correction coefficient (k) is determined based on the magnitude of the deviation of the dot position measured in advance as described above.
[0028]
Next, the “ink” used in the embodiment of the present invention will be described.
As the ink used in the present embodiment, water-based ink used in general offices and homes, solvent-based ink and oil-based ink used for signboards, and photocurable ink suitable for a wide range of base materials are used. Can be.
In particular, photocurable inks are preferable for inkjet printers with high productivity because the drying time is short. As the photocurable ink, a radical polymerization ink described in WO99 / 29787, a cationic polymerization ink described in JP-A-2002-317139, and an aqueous ultraviolet-curable ink described in JP-A-2002-187918 can be used. . Above all, an ultraviolet curable ink containing neither water nor a solvent is preferable.
[0029]
Next, the recording medium K used in the embodiment of the present invention will be described. As the recording medium K, a recording medium made of various types of paper such as plain paper, recycled paper, glossy paper, various fabrics, various nonwoven fabrics, resin, metal, glass, etc., which is applied to an ordinary ink jet type image recording apparatus is applied. It is possible. Further, as a form of the recording medium K, a roll shape, a cut sheet shape, a plate shape, or the like can be applied. In particular, as the recording medium K used in the present embodiment, a transparent or opaque non-absorbable resin film used for flexible packaging can be applied. Specific types of resin for the resin film include polyethylene terephthalate, polyester, polyolefin, polyamide, polyesteramide, polyether, polyimide, polyamideimide, polystyrene, polycarbonate, poly-ρ-phenylene sulfide, polyetherester, and polyvinyl chloride. , Poly (meth) acrylate, polyethylene, polypropylene, nylon and the like are applicable, and furthermore, copolymers of these resins, mixtures of these resins, and those obtained by crosslinking these resins are also applicable. In particular, the choice of stretched polyethylene terephthalate, polystyrene, polypropylene, or nylon as the resin type of the resin film is important in terms of transparency, dimensional stability, rigidity, environmental load, cost, etc. of the resin film. It is preferable to use a resin film having a thickness of 2 μm or more and 100 μm or less (preferably 6 μm or more and 50 μm or less). Further, the surface of the resin film support may be subjected to a surface treatment such as a corona discharge treatment and an easy adhesion treatment. Further, as the recording medium K used in the present embodiment, known opaque recording media K such as various kinds of paper coated on the surface with a resin, a film containing a pigment, and a foamed film can be applied.
[0030]
Next, the operation of the inkjet printer 1 during image recording will be described. The following operation is performed in a state where the recording medium K is transported in the transport direction A by the transport device.
[0031]
First, when an image signal is input to the control device, the control device multiplies the density value (A) to be expressed by each correction coefficient (k) in the table to obtain a liquid to be discharged from each nozzle 30. Calculate the number of drops (A × k). As a result, as shown in FIG. 4B, the number of ink droplets to be ejected for a pixel whose density value decreases due to a shift in dot position increases, and for a pixel whose density value increases. The number of ink droplets to be ejected is reduced. Accordingly, the number of ink droplets to be ejected from each of the nozzles 30a to 30g is changed from 5 to 4, 6, and 7, respectively, so that approximately 5 ink droplets land on each pixel on the recording medium K. Drops are changed to three drops, five drops, six drops, and five drops.
[0032]
Next, the control device controls the piezoelectric element drive circuit 33 so as to eject the calculated number of droplets (A × k) of ink from each of the nozzles 30a to 30g. Next, the piezoelectric element drive circuit 33 applies a voltage to the predetermined piezoelectric element 32 via the lead wire 32a and the electrode 32b, and expands the piezoelectric element 32 upward. As a result, the ink flow path 35 is compressed, the ink is ejected from the nozzles 30a to 30g, and approximately five drops of ink land on each pixel of the recording medium K.
Then, as the recording medium K is transported, the ink on the surface of the recording medium K is irradiated with ultraviolet rays from the ultraviolet irradiation device 4 immediately after landing, and as a result, the ink is cured on the surface of the recording medium K.
[0033]
According to the above-described ink jet printer 1, since substantially the same amount of ink can be landed on each pixel of the recording medium K, unlike the related art, streak-like unevenness occurs along the transport direction A. Can be prevented. Therefore, even when the positions and directions of the nozzles 30a to 30g are shifted due to a manufacturing error or the like, it is possible to prevent the image quality from being deteriorated due to a shift in the ink landing position.
Further, even in the inkjet printer 1 in which the positions and the directions of the nozzles 30a to 30g are shifted, a high-quality image can be recorded. Therefore, the recording is performed finely so that a manufacturing error does not occur in the positions and the directions of the nozzles 30a to 30g. There is no need to manufacture the head 3. Therefore, the manufacture of the inkjet printer 1 can be facilitated, and the manufacturing cost can be reduced accordingly.
[0034]
Further, since the recording head 3 is of a line type, an image can be recorded at a higher speed than in the case where the recording head 3 is of a serial type.
Further, since the ink is an ultraviolet curing type ink, the ink that has landed on the surface of the recording medium K can be immediately cured by the ultraviolet irradiation device 4. Therefore, a high-quality image with little blur and blur can be recorded.
[0035]
In the first embodiment, the ink is described as an ultraviolet curable ink. However, an ink such as a water-based ink that cures by a method other than the irradiation of ultraviolet light may be used.
In addition, the control device has been described as preventing the image quality from being reduced by changing the number of ink droplets ejected from each of the nozzles 30a to 30g. Alternatively, the image quality may be prevented from deteriorating by changing the number of droplets and changing the amount of ink per droplet.
[0036]
Further, the control device has been described as preventing the image quality from deteriorating by compensating for the shift of the dot position in the width direction B. In addition, the control device shifts the ejection timing of each of the nozzles 30a to 30g to thereby reduce the conveyance direction. The deviation of the dot position along A may be compensated.
[0037]
Further, the ultraviolet irradiation device 4 has been described as being arranged downstream of the four recording heads 3,... In the transport direction A. However, as shown in FIG. On the other hand, they may be arranged on the upstream side and the downstream side in the transport direction A, respectively.
Although the image recording apparatus 2 has been described as including four recording heads 3, it may be provided with only one as shown in FIG.
[0038]

This control device, like the control device in the inkjet printer 1, changes the ink ejection amount of each nozzle in order to compensate for the deviation of the dot position in the transport direction A.
[0042]
Next, the operation of the inkjet printer 1A will be described. In the second embodiment, for the sake of convenience, it is assumed that an image signal for instructing each control nozzle to eject the same number of ink droplets is input to the control device.
Image recording by the inkjet printer 1A includes a recording step of discharging ink onto the recording medium K and curing the ink, and a transporting step of transporting the recording medium K.
[0043]

And the ultraviolet irradiation devices 4A, 4A while the recording medium K is not being conveyed. At the time of this scanning, the control device determines the number of ink droplets ejected from each nozzle of the recording heads 3A,. Make changes based on Next, the nozzles of the recording heads 3A,... Eject the changed number of droplets of ink. Next, the ultraviolet irradiation device 4A irradiates the ink that has landed on the recording medium K with ultraviolet light.
Next, in the transport step, the recording medium K is transported in the transport direction A as appropriate.
Thereafter, desired images are sequentially recorded on the surface of the recording medium K by repeating the above operations.
[0044]
According to the above-described ink jet printer 1A, substantially the same amount of ink can be landed on each pixel of the recording medium K as in the ink jet printer 1, so that unlike the related art, The occurrence of streak-like unevenness can be prevented. Therefore, even if the position or direction of the nozzle is shifted due to a manufacturing error or the like, it is possible to prevent the image quality from being deteriorated due to a shift in the ink landing position.
[0045]
In the second embodiment, the description has been made assuming that two ultraviolet irradiation devices 4A are mounted on the carriage 7 while being arranged on both sides of the four recording heads 3A,.
