BACKGROUND OF THE INVENTION
The present invention relates to a method and apparatus for recording a high-viscosity substance by depositing it on a recording medium in the form of dots in accordance with an electrical signal.
[0002]
[Prior art]
The ink jet recording method is a recording method in which an image is formed by causing a small droplet of ink to protrude and fly from a fine nozzle and directly adhere to a recording member such as paper. Printers based on this recording method are now widely used as printers for offices and general homes because of their low cost, high quality, miniaturization of devices, and easy colorization.
[0003]
Such a printer method is generally a continuous method in which ink droplets are continuously projected and only useful ones selectively reach the recording medium according to the image signal, and discontinuously according to the image signal. There are two types of drop-on-demand systems in which only useful droplets protrude. Furthermore, in the latter case, a piezo method in which the ink flow path is deformed by the vibration of the piezoelectric element and the ink is protruded, bubbles are generated in the ink by the heat from the heating element in the ink flow path, and the ink is protruded by the pressure. Recording methods such as a thermal method and an electrostatic method in which an electrostatic attraction force is applied to the ink to make it protrude have been proposed. In particular, the electrostatic method has attracted attention unlike the other methods in that the structure of the recording head is simple and multi-nozzle formation is easy, and that gradation expression is possible by pulse width modulation.
[0004]
As a general disadvantage of these ink jet methods, there is a problem of bleeding when printing on a recording medium. The ink is dried on the recording medium by penetrating into the recording medium and evaporating volatile components. Therefore, when printing on uncoated paper or cloth, the landed ink spreads along the fiber by capillary action, giving an image with a blurred outline. In addition, when printing is performed on a film or metal that does not absorb ink at all, the ink cannot permeate, so that a very long time is required for drying and fixing. Further, when color recording is performed regardless of the recording medium, other inks are sequentially stacked before the ink that has been attached first is completely fixed, and thus blurring occurs at the color boundary.
[0005]
Such problems can be solved by using high-viscosity inks. However, in the conventional ink jet technology, it is common to use inks having a viscosity of about several CPS, and even a high one can only record up to about 20 CPS. I could not.
[0006]
As a general technique for solving the problem of bleeding without using high-viscosity ink, an ink adsorption layer is provided on the surface of a recording medium. However, this method has a problem in that the recording medium becomes expensive and the unique texture of paper, film, etc. is impaired, and it is currently used only in fields where these are acceptable. Therefore, it has been considered that most of image formation on paper, film and the like that has been performed by the conventional printing method cannot be replaced by the ink jet method.
[0007]
As one of attempts to solve the above-described drawbacks, a so-called solid ink jet method has been proposed in which a solid ink at room temperature is dissolved and reduced in viscosity when necessary. The ink used here is mainly composed of wax, and is supplied to the nozzle portion in a melted state by heating at around 100 ° C., and rapidly solidifies when ejected. There is nothing. However, in this case, it takes time to melt the ink, so it takes a long time to warm up until recording is possible after the power is turned on, and it is always heated to maintain the melted state even after warming up. There was a need. In addition, the ink swells on the recording medium, resulting in a gritty texture, and the image often has a glossy design.
[0008]
As a result of extensive research on recording a high-viscosity material having a viscosity of 300 CPS or higher, which has been impossible with the conventional ink jet technology, the present inventor has filled a high-viscosity material into a nozzle having a recording electrode disposed in the vicinity of the outlet. After forming the protruding portion of the high-viscosity material at the tip, applying an electric pulse according to the image signal of the recording electrode causes the protruding portion of the high-viscosity material to vibrate or less than the protruding portion of the high-viscosity material. It was found that the droplets flew and minute dots were recorded on the medium. According to this method, recording can be performed without greatly reducing the viscosity during recording as in the case of the solid ink jet method, and there is no blur even when recording on a medium such as plain paper, cloth, film, metal, or the like. Sharp images can be obtained.
[0009]
However, even in this method, when recording high-density dots, the amount of the high-viscosity substance adhering to the medium becomes large, so that the dots rise and undesirably unevenness may be formed.
[0010]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and a first object thereof is to pattern a thin film dot by discharging a high-viscosity material having a viscosity of 300 CPS or more, which is impossible with the conventional ink jet technology. It is to provide a recording method and apparatus that can be used.
The second object is to provide a recording method and apparatus capable of forming an image having a texture similar to offset printing on plain paper, film, metal or other recording media.
[0011]
[Means for Solving the Problems]
In order to achieve each of the above objects, the present invention provides a nozzle in which a recording electrode is disposed in the vicinity of an outlet filled with a high-viscosity substance having a viscosity of 300 CPS or more, and a portion where the high-viscosity substance protrudes at the nozzle tip (hereinafter referred to as a meniscus part) After that, by applying an electric pulse according to the image signal of the electrode, the protruding part of the high-viscosity substance is vibrated or a droplet is ejected from the protruding part of the high-viscosity substance. Then, after adhering to a transfer medium disposed opposite to the nozzle, the image is transferred to a recording medium, and an image of a high viscosity substance is obtained on the recording medium.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail through embodiments.
An example of nozzles used in the recording system of the present invention is shown in FIG. 1, and a schematic diagram of a recording head constituted by a plurality of nozzle arrays is shown in FIG. Note that 10 is a nozzle, 11 is a high-viscosity substance, 12 is a recording electrode, 13 is a meniscus, 14 is a piezoelectric element, 15 is a recording medium, 17 is a transfer medium, 18 is an impression cylinder, and 20 is a recording head.
In FIG. 1, a high viscosity substance 11 is filled in a nozzle 10 provided with a recording electrode 12 in the vicinity of the tip outlet by a pressurizing means (not shown), and the recording of the high viscosity substance filled in the nozzle 10 is performed. Then, an appropriate signal voltage is applied to the transfer medium 17 so that a high-viscosity substance is adhered to the transfer medium 17 and then transferred to the recording medium 15 fed between the transfer drum and the impression cylinder 18.
[0013]
The nozzle 10 is made of an insulating material or metal and is formed in a rectangular parallelepiped shape or a cylindrical shape. An ink chamber (not shown) for storing and replenishing the high-viscosity substance 11 is connected to the rear part of the nozzle, and the high-viscosity substance 11 is pressurized and supplied to the nozzle part by pressurization means (not shown) on the back side. Is done. The pressurization is performed continuously or intermittently at an appropriate pressure to keep the shape of the meniscus 13 constant. In order to perform more stable recording, it is preferable to provide a piezoelectric element 14 as another pressurizing means in the nozzle as shown in FIG. 1 and pressurize the high viscosity substance in synchronization with the voltage application to the recording electrode 12. . A piezoelectric element such as a piezo element is preferably used as the pressurizing means that can synchronize with voltage application.
[0014]
The front portion of the nozzle is an opening having a diameter of 200 μm or less, and a high-viscosity substance protruding further forward forms a hemispherical or cone-shaped meniscus 13. It is preferable to use a material having a high surface free energy such as Teflon so that the high-viscosity material does not spread out as the material in front of the nozzle. If the high-viscosity material spreads wet, the meniscus shape becomes unstable and remains as dirt when the power is turned off, which adversely affects subsequent recording.
[0015]
When the nozzle material is insulative, the recording electrode is disposed in the vicinity of the nozzle tip, but may be inside or outside the nozzle wall. Preferably, it is provided outside the nozzle wall in order to eliminate the influence of corrosion or the like due to the high viscosity substance. The distance from the nozzle tip of the recording electrode 12 is not particularly limited. From this, it can be seen that the recording principle of the present invention is completely different from the conventional electrostatic ink jet method. The present inventor has found that, when the position of the recording electrode is separated from the nozzle tip without changing the applied voltage, recording of a high-viscosity substance is possible even when the recording electrode is separated from the nozzle tip by 10 cm or more. I found it. Such a degree of freedom of electrode arrangement is a great advantage in the design of nozzles and further in the design of multi-nozzle heads.
[0016]
On the other hand, depending on the type of high-viscosity substance, defects such as corrosion and clogging due to contact with the recording electrode may be ignored. In this case, the nozzle is made of metal, and it is also possible to apply a signal voltage directly to the nozzle without providing a recording electrode.
[0017]
When the nozzle is disposed facing the transfer medium, there are the following two changes that occur in the meniscus portion at the tip of the nozzle due to voltage application to the recording electrode.
(1) The meniscus vibrates (stretches) in the direction of the transfer medium, and adheres to the transfer medium in a stretched state to form dots.
{Circle around (2)} The meniscus tip splits, and the separated droplets fly and adhere to the transfer medium to form dots.
Which of the above phenomena occurs depends not only on the type of high-viscosity substance, but also on how the voltage is applied and the nozzle material. Although it is possible to form sharp dots by any phenomenon, the principle of these phenomena is not well understood.
[0018]
The distance between the nozzle and the transfer medium is set in the range of 0.1 mm to 10 mm, more preferably 0.1 to 3 mm. If the distance is narrower than 0.1 mm, a stable meniscus cannot be formed, and it becomes impossible to follow the fine irregularities of the transfer medium. This is not preferable because dots are connected or missing. On the other hand, when the width is larger than 10 mm, the dots spread and a sharp image cannot be recorded.
[0019]
As the transfer medium, a metal cylinder laminated with a rubber layer is used. The properties required for transfer media are:
(1) Acceptability and transferability of high viscosity materials (2) Chemical resistance (3) Thickness accuracy (4) Elongation (5) Restorability (6) Impact resistance (7) Elasticity (hardness, compressibility)
(8) Surface properties (9) Detergency, etc., but it is necessary to design individually according to the high viscosity substance to be recorded. The hardness of the rubber layer is evaluated by a rubber hardness tester, but when used for general paper, one having a range of 78 ° to 80 ° is used. Those having a low hardness are thick paper and embossed paper having a rough surface, and those having a high hardness are used for metal printing, offset printing paper, and the like. When offset ink is used as the high-viscosity material, a blanket similar to that used in an offset printing machine can be used as a transfer medium, and various conditions such as nip pressure can be used as they are. In any case, in order to reduce the problem of untransferred, it is necessary to use silicon rubber for the rubber layer itself or to provide a layer having a low surface free energy such as silicon or fluororesin on the surface of the rubber layer. preferable.
[0020]
This recording method is a method in which a high-viscosity substance having a viscosity of 300 CPS or more is adhered to a transfer medium in a non-contact manner and then transferred to the recording medium to form a pattern. The high-viscosity material used is not limited in the form of liquid, colloid, paste, etc., as long as it has fluidity.
[0021]
Examples of high-viscosity substances that can be recorded in the present invention include resin materials such as UV curable resins, epoxy resins, and acrylic resins and solutions thereof, solid materials such as paraffin wax and carnauba wax liquefied by heating, copper phthalocyanine, and the like High-concentration dispersion of inorganic pigments such as organic pigments and titanium oxide, polyhydric alcohol materials such as glycerin, UV curable adhesives, hot melt adhesives, pressure sensitive adhesives, 1-component and 2-component epoxy systems Various adhesives such as adhesives, rubber adhesives, cyano adhesives, anaerobic adhesives, semiconductor-related materials such as conductive paste, cream solder, resist, silicon oil, industrial oil, engine oil, grease, etc. Various lubricants, sauces, food materials such as ketchup, enamel, lacquer, paint, various printing inks, concentrated liquids Toner, writing instrument inks, various coloring materials such as water-oil-based paints, and the like.
[0022]
The thing which has thixotropic property as a high viscosity substance preferable for using in this invention is mentioned. Thixotropy is a phenomenon in which the apparent viscosity temporarily decreases due to deformation, particularly shearing, and when it is allowed to stand, it returns to its original high viscosity state. This phenomenon is observed in certain colloidal systems, particularly suspensions, and has been confirmed in some polymer solutions. The decrease in viscosity in thixotropy is interpreted to be due to the continuous structure formed by the traction of the dispersed particles in the suspension being re-formed while the system is standing.
[0023]
When such a substance is used in the present invention, a viscosity gradient is generated in the high-viscosity substance in the nozzle due to the degree of shearing, which has a favorable effect on recording. That is, the tip of the meniscus is sheared by vibration or splitting due to a signal voltage to lower the viscosity, and the portion can move to the recording medium side with smaller energy. On the other hand, since a large shear is not applied except at the tip of the meniscus, the viscosity is sufficiently high and the transfer to the transfer medium side is relatively difficult. In addition, stabilization of the meniscus shape due to gravity and sagging of a highly viscous material during non-recording are unlikely to occur. Furthermore, from these characteristics, even when nozzles having the same inner diameter are used, smaller dots can be formed, and safety during continuous recording is improved.
[0024]
The degree of thixotropy described above includes η ₁ ≧ 300 CPS and η ₁ when the apparent viscosity η _{1 at} a shear rate of 0.1 (1 / sec) and the apparent viscosity at a shear rate of 100 (1 / sec) as η _{2. 1} ≧ η ₂
It is preferable to have the following relationship.
[0025]
When the high-viscosity substance used in the present invention does not have thixotropic properties, the so-called thixotropic agent can be added to impart thixotropic properties and improve the recording performance. A thixotropic agent is a substance that forms a certain structure in the system by adding a small amount, imparts an appropriate thixotropic property to the system, or gives a thickening effect, specifically, ultrafine silica. , Clay minerals such as montmorillonite and kaolinite and derivatives thereof, polyamide wax, hydrogenated castor oil, polyethylene oxide, surfactant and the like.
[0026]
Depending on the high-viscosity substance, the dots at the time of recording may not be dispersed and the thread may be pulled, resulting in a linear connection. In such a case, the recording characteristics are improved by heating the meniscus portion. The effect of heating is not only on the decrease in viscosity but also on the electrical conductivity and surface tension, and it seems that the recording characteristics are actually improved by these composites. The action of heating is complex and difficult to predict, but it has been confirmed that there is an optimal temperature range depending on the type of high viscosity material.
[0027]
The heating means may be provided with a heater in the nozzle, but is often not suitable for warming the meniscus portion. A method such as sending warm air to the meniscus portion or irradiating an infrared lamp is preferably used.
[0028]
FIG. 3 shows the configuration of the nozzle when heated by warm air. In the case of warm air, the safety of recording may be impaired depending on the wind direction. Therefore, in order to minimize the influence of the wind direction, as shown in FIG. It is preferable to enclose the cylindrical body or the rectangular parallelepiped 16 and to send warm air from the air blowing port and send it from the upper part of the nozzle toward the transfer medium.
[0029]
FIG. 4 is a schematic configuration diagram of a high viscosity substance recording apparatus to which the present invention is applied.
In this apparatus, a film-like recording medium is supplied from a roll, but the material and shape of the recording medium are not particularly limited.
A power source and a pulse generator (not shown) are connected to the electrode portion of the recording head 1 so that a voltage signal corresponding to the pattern can be applied. The heater 7 can supply hot air at a constant temperature from room temperature to 100 ° C., and the air volume can be adjusted. A pressurizing device 6 is connected to the rear portion of the recording head 1, and pressurization of a high-viscosity substance is performed to keep the meniscus shape constant. When recording a plurality of high-viscosity substances, this can be dealt with by arranging a plurality of similar heads.
[0030]
The high-viscosity substance recorded in a pattern on the transfer medium 2 on the rotating drum by the recording head 1 moves to the transfer portion by the rotation of the transfer medium drum, and is pressure-transferred onto the recording medium 3 wound around the surface of the copper 8. Is done. Thereafter, drying is performed according to the high-viscosity substance in the drying unit and fixed.
[0031]
Drying is performed by evaporation of a high-viscosity solvent, UV irradiation, EB irradiation, or the like. In the examples described below, since the high-viscosity substance is UV curable, the UV irradiation device 4 is used in the drying process. The recording medium which has been dried is cut into a desired size by the cutter 5, and a series of steps is completed.
[0032]
【Example】
A recording test of a high-viscosity substance was performed using the apparatus shown in FIG. The recording nozzle 1 was the same as that shown in FIG.
In this example, a UV curable ink for offset printing without water was used as the high viscosity substance. The rheological properties of this ink at 50 ° C. are shown in FIG. In FIG. 5, the horizontal axis is the shear rate (1 / s), and the vertical axis is the viscosity.
Further, Table 1 shows the apparent viscosity eta ₂ at an apparent viscosity eta ₁ and a shear rate of 100 (1 / sec) at a shear rate of 1.0 (1 / sec). It can be seen that this ink has sufficient thixotropy at 50 ° C.
[0033]

When the high-viscosity substance image transferred to the recording medium was observed with a microscope, circular dots having a diameter of 60 μm were arranged at regular intervals without any omission of recording. Further, the image obtained from each dot having a thin film shape with a thickness of 1 μm or less exhibited a texture similar to that of offset printing.
Further, when the transfer medium after recording was observed, no transfer residue or dirt was observed, and it was confirmed that the transfer was performed with an efficiency of almost 100%.
[0035]
