Field of the Invention The present invention relates to a printing apparatus and a printing method, and more particularly to a high-precision printing such as offset printing or reverse printing. Printing device and printing method. [Prior Art] In recent years, in order to meet the demand for large-scale and low-cost display devices, a pattern of a color filter layer or a plasma display panel (PDP) for forming a liquid crystal color filter by printing has been proposed. A scheme of a pattern of a silver electrode or the like in an electrode substrate. Further, these patterns are fine patterns and are required to have excellent printing precision, and thus the application of gravure offset printing using a ketone rubber blanket has been studied. However, the electrode substrate of the liquid crystal filter or the PDP is a substrate that does not absorb the ink solvent such as glass. Therefore, in the process of repeating the printing process on a plurality of substrates, the ink solvent permeates and accumulates in the rubber cloth to swell the rubber cloth. Further, there is a case where the transfer of the ink is poor or the dimensional accuracy of the pattern is lowered, and the defective product is increased. Therefore, as a technique for removing the ink solvent soaked and accumulated in the rubber cloth from the rubber cloth, the patent document proposes a solvent absorbing mechanism for bringing the rubber cloth and the solvent absorbing body into rotational contact. Patent Document 2 proposes a mechanism for pressing a hygroscopic sheet to a rubber sheet and adjusting the level (degree) of the rubber sheet to a wet state in accordance with the ink solvent. Further, Patent Document 3 describes a device in which a strip-shaped solvent absorber is wound around a roll (r〇Uer), and the solvent absorber is successively discharged to make a portion of the peripheral surface of the rubber sheet with 5 29585 pif. The oxime rubber layer of the contact (transfer roller) was transferred from the rubber fabric to the solvent absorber (see Fig. 3). The ink _ layer from the surface of the rubber sheet is absorbed, and the solvent absorber is heated by the second statement described in Patent Document 4, and the solution is described as the heat absorption from the solvent absorption body. It is a solvent removal mechanism of the == agent (refer to the patent document 1) JP-A-2000-158633, Patent Document 2, JP-A-200-158862, Patent Document 3, JP-A-K8 In the inventions described in Patent Documents 1 to 4, the solvent absorption mechanism (the solvent absorber, the moisture absorption sheet, or the solvent absorber) is repeatedly transferred from the rubber cloth in the invention described in JP-A-2006-035769. In the treatment of the ink solvent, the ink solvent is impregnated and stored in the solvent absorption mechanism. Further, the solvent absorption mechanism is saturated with the ink solvent. To eliminate the suction effect, the ink solvent saturation may be lowered, for example, the solvent absorption mechanism may be replaced. In this case, the productivity of printing is lowered and the cost is increased. Therefore, as in Patent Document 4, it is considered to evaporate the solvent by heating the solvent absorber, but for forming a liquid crystal color filter. The ink of the color filter layer generally uses a glycol ester having a relatively high boiling point (about 200 to 280 ° C) as a solvent, and in order to evaporate by heating the glycol, it is necessary to set the heating temperature to Very high. 1376313 29585pif basin 2 2 filter "color layer, etc., requires extremely high precision printing of extremely small, field patterns when the 'printing device is installed in the clean room, in a very narrow temperature range Strict temperature management is carried out. Therefore, when the == thermal solvent absorber is included in the temperature management of the clean room, the object of the present invention is to provide an efficient storage of the solvent in the solvent absorber. A printing apparatus and a printing method for removing the solvent of the ink of the rubber cloth are removed. In order to achieve the above object, the brush apparatus of the present invention is characterized in that it is provided for transferring the object to be printed. a rubber cloth carried on the surface, and an eraser for fixing the rubber cloth on the surface for sucking in the rubber cloth by contact with the outer peripheral surface of the rubber (four) An ink-soluble solvent absorber, and a solvent suction mechanism for sucking the solvent absorbed by the solvent-based absorber to dissolve the solvent-containing body towel and not contacting the solvent absorber. For the above-mentioned i-th printing device In other words, when the solvent suction mechanism is not in contact with the solvent absorber, the ink solvent that has been sucked from the rubber cloth to the solvent absorber can be removed from the solvent absorber. Therefore, the first print job described above is used. It is possible to prevent damage or deterioration of the surface of the solvent absorber due to contact with a member for removing a solvent. Further, heat treatment for removing the ink solvent from the solvent absorber is not required, thereby being able to prevent printing In the first printing apparatus of the present invention, preferably, the solvent suction mechanism is 7 ^ 76313 29585 pif (1) spaced apart from the surface of the solvent absorber by a predetermined interval and a suction nozzle disposed oppositely to the granule absorber, or (2) a vacuum chamber for covering and sealing the solvent absorber. > When the granule aspirating means is the suction nozzle of the above (1), the solvent sucked from the rubber cloth to the solvent absorbing body can be removed from the solvent by a simple structure. ▲ On the other hand, when the solvent suction mechanism is the vacuum chamber of the above (2), the solvent sucked from the rubber cloth to the solvent absorber can be efficiently sucked and removed from the entire absorbent body. Therefore, in the above (1) or (2), the fourth (4) is to be high in the solvent, and the second printing device of the present invention is characterized in that: Surface transfer oil refining surface rubber cloth; a rubber cylinder for fixing the rubber cloth on the surface; and contacting the outer peripheral surface of the rubber cloth to absorb a solvent absorber penetrating into the solvent of the second: H oil; For obtaining the solvent: force: = is evaporated by the solvent solvent sucked by the solvent absorber to remove '===== with the rubber cloth roll, and for cooling the ring ring In addition to the plurality of ribbons, the cooler can also be mounted on a plurality of rollers. In the second printing apparatus described above, the heating means for picking up the tape into the endless belt as the solvent absorber can be removed from the solvent absorber, and the sputum is set to be in the solvent 8 1376313 A cooler on the 29585pif absorber cools the heated endless belt. Therefore, according to the second printing apparatus described above, it is possible to absorb and absorb the ink solvent to be absorbed by the simple method of evaporation by heating. Further, the heated endless belt can be rapidly cooled by the cooler, whereby an excessive burden on the temperature management of the printing apparatus can be prevented. In the first printing method of the present invention, the printing method of the first printing apparatus according to the present invention is characterized in that the ink carrying step of carrying the ink on the surface of the φ rubber cloth is carried out. a printing step of printing ink on the surface of the rubber sheet onto the object to be printed, a solvent aspirating step of sucking the ink solvent infiltrated into the rubber cloth by the solvent absorber, and a non-contact state by the solvent suction mechanism A solvent absorption step of aspirating the solvent absorbed by the solvent absorber. In the above-described first printing method, the solvent aspirating step can suck the solvent sucked from the rubber cloth into the solvent absorber in a state in which it is not in contact with the solvent absorber by the solvent suction means, and the solvent can be absorbed from the solvent absorber. Remove. Therefore, according to the above-described second printing method, it is possible to prevent the surface of the solvent absorber from being damaged or deteriorated by contact with the member for removing the solvent. Further, heat treatment for removing the solvent from the solvent absorber is not required, whereby an excessive load on the temperature management of the printing apparatus can be prevented. The second printing method of the present invention is a printing method using the second printing apparatus of the present invention, and is characterized in that the following steps are provided: an ink supporting step of supporting the ink on the surface of the rubber sheet, and supporting the rubber a printing step of printing the ink on the surface of the cloth onto the object to be printed, a solvent absorption step of absorbing the ink solvent infiltrated into the rubber cloth t by the solvent absorption 9 1376313 29585pif body, and absorbing the solvent by the heating mechanism The solvent evaporation removal step of evaporating and removing the solvent extracted in the body, and the cooling and cooling process for cooling the subsequent solvent-like body. For the second printing method, the solvent extraction step is used to add money. The heating is carried out to evaporate the solvent from the rubber to the annular (four) ink as the solvent 2, so that the solvent is absorbed from the solvent absorber and the wire is filled with the cooler by the cooler disposed on the solvent absorber. Bring in ί cooling. Therefore, by using the second printing method described above, the solvent can be used in a solvent: Si: this method: the solvent of the solvent absorber can be prevented from being over-transparent by the temperature management of the printing device, and the printing method can be efficiently performed. The solvent is absorbed in a solvent-immersed solvent. In addition, it is thereby possible to prevent: the productivity of the printing caused by the liter exchange is reduced, the cost-up printing and printing method is suitable for the color of the silver electrode two liquid crystal filters such as offset printing, coffee, and the color of the liquid crystal is clearly understood as ? = two to: his purpose, characteristics and advantages can be described in more detail below.

In the printing method using the printing apparatus 1, the solvent absorbing step of removing the solvent from the solvent absorbing body 6 without the first solvent absorbing means 7 (suction nozzle 14) and the solvating body 6_ is provided. In the solvent absorption step, first, the pair of rolls, 12 supporting the solvent absorber 6 are disposed in the above-described leaving state (the state shown by the solid line in Fig. j). Then, the solvent absorbent body 6 is rotated between the pair of rolls 11, 12 and a tensioning guide 13, and the vicinity of the surface of the solvent absorbent body 6 is sucked by the suction nozzle 14. Thereby, the vicinity of the surface of the solvent absorber 6 becomes a negative pressure, and the ink in the solvent absorber 6 is sucked and removed from the solvent WEB 6.

Further, when the slit interval (longitudinal opening width) is larger than the above range, although the suctioned area can be increased, the suction degree is lowered. Further, when the upper slit spacing (longitudinal opening width) is lower than the above range, although the suction degree is increased, the suctioned area becomes very narrow, and it is excessively used in the 'suction control per unit area'. The time may reduce the efficiency of solvent absorption. Further, from the viewpoint of improving the solvent suction efficiency, the interval between the surface of the solvent absorber 6 and the opening portion of the suction nozzle 14 is preferably as narrow as possible, but on the other hand, when it is lower than the above range, the solvent is absorbed.

Further, in the solvent abatement step, the moving speed of the solvent absorber 6 is, for example, 5 to 60 mm/s', preferably 10 to 40 mm/s. This moving speed can be adjusted by controlling the rotational speed of the engine connected to the tension roller 13. Further, the time for performing the suction treatment using the suction nozzle 14 is, for example, 1 to 50 seconds, preferably 5 to 30 seconds. The solvent aspirating step is repeated, and a large amount of solvent permeates into the solvent absorber 6 'when saturated', the solvent absorber 6 can no longer absorb the solvent, but after the solvent absorption step, the solvent absorber 6 can be inhibited from coming from the rubber cloth. The effect of the suction treatment of the ink solvent of 2 is lowered over time. Further, for example, the above-described series of printing treatments are carried out using an ink having a higher boiling point (200 to 280 (about:)) as a solvent, as a solvent absorber 6 for sucking a solvent derived from a rubber cloth, When the solvent absorbing layer 8 is made of a urethane resin, the solvent absorbing step is repeated for about 30 to 100 times, and about 50 times, the solvent absorber 6 is saturated.

另外;_當氣體嗔嘴15的上述狹缝間隔（縱開口寬度） 大於上述範圍時’向溶劑吸收體6吹送的氣體容易擴散， 可成會難以獲付使抽吸嘴14的賴抽吸效率提高的效 果。此外’ ^上述狹縫間隔（縱開口寬度）低於上述範圍 時’由於吹送氣體的面積非常狹窄，因此可能會難以獲得 使抽吸嘴14的溶劑吸除效率提高的效果。 此外’>谷劑吸收體6的表面與氣體喷嘴15的開口部之 間的間隔’根據使抽吸嘴14的溶劑抽吸效率提高的觀點， 最好是盡可能地窄。另—方面，低於上述範圍時，由於溶 劑吸收體6和氣體喷嘴15的接觸，可能會使溶劑吸收體6 受到損傷。 超聲波振子16例如夾著溶劑吸收體6，配置在與抽吸 21 1376313 29585pif 嘴14對向的位置或者相對於該對向位置而配置在溶劑吸 收體6的旋轉方向的上游側。一邊從該超聲波振子16二對 溶劑吸收體6賦予超聲波振動，一邊藉由用抽吸嘴丨4進行 抽吸，可以進一步提高從溶劑吸收體6抽吸溶劑的效率= 超聲波振子16可以使用例如壓電陶瓷等的各種超聲 波振子。此外’對溶劑吸收體6施加的超聲波振子的頻率，Further, when the slit interval (longitudinal opening width) of the gas nozzle 15 is larger than the above range, the gas blown to the solvent absorber 6 is easily diffused, and it may become difficult to obtain the suction efficiency of the suction nozzle 14. Improve the effect. Further, when the slit interval (longitudinal opening width) is lower than the above range, the area of the blowing gas is extremely narrow, so that it is difficult to obtain an effect of improving the solvent absorption efficiency of the suction nozzle 14. Further, the 'interval between the surface of the granule absorber 6 and the opening of the gas nozzle 15' is preferably as narrow as possible from the viewpoint of improving the solvent suction efficiency of the suction nozzle 14. On the other hand, when it is less than the above range, the solvent absorber 6 may be damaged due to the contact of the solvent absorber 6 and the gas nozzle 15. The ultrasonic vibrator 16 is disposed on the upstream side in the rotational direction of the solvent absorbent body 6 at a position opposed to the suction 21 1376313 29585 pif nozzle 14 or at a position opposite to the opposite position, for example, with the solvent absorber 6 interposed therebetween. By applying ultrasonic vibration to the solvent absorber 6 from the ultrasonic vibrator 16 and sucking by the suction nozzle 4, the efficiency of pumping the solvent from the solvent absorber 6 can be further improved. For example, the ultrasonic vibrator 16 can be used. Various ultrasonic vibrators such as electric ceramics. Further, the frequency of the ultrasonic vibrator applied to the solvent absorber 6,
根據溶劑吸收體6的形成材料或溶劑種類進行適當選擇即 可，例如被設定在1〜5MHz的範圍内。 超聲波振子16最好是與溶劑吸收體6的背面密合。此 外，當通過超聲波振子16來翁收體6施加超聲°波振 動時，溶劑吸收體6的移動速度例如是3〜6〇mm/s，優選 5〜30mm/s。 若上述印刷裝置1實施上述的印刷方法，則能夠 溶劑吸收體6的對來自橡膠布2的油墨溶劑的吸取處 果經時，低的情況，而且能夠使高精度印刷中的印刷生 產率提高。The material of the solvent absorber 6 or the type of the solvent may be appropriately selected, for example, in the range of 1 to 5 MHz. The ultrasonic vibrator 16 is preferably in close contact with the back surface of the solvent absorber 6. Further, when ultrasonic vibration is applied to the body 6 by the ultrasonic vibrator 16, the moving speed of the solvent absorber 6 is, for example, 3 to 6 mm/s, preferably 5 to 30 mm/s. When the printing apparatus 1 described above is subjected to the above-described printing method, the absorption of the ink solvent from the rubber cloth 2 by the solvent absorber 6 can be made low, and the printing productivity in high-precision printing can be improved.

Further, the tension applied to the blanket 2 was adjusted in the range of 20 to 30 kN in accordance with the measurement result of the line width of the stripe pattern after printing. Further, in the following Examples 1 and 2, similarly to the solvent aspirating step, the solvent suction step was carried out every time the printing process consisting of the ink supporting step and the printing step was performed once. In the following Example 3, in the same manner as the solvent aspirating step, the solvent evaporation removal step was carried out every time the printing process consisting of the ink supporting step and the printing step was performed once. 28 1376313 29585pif • Example 1: The solvent absorption step of the above printing test was carried out by suctioning the solvent absorber 6 while moving at a speed of 3 〇mm/s while sucking with a suction nozzle 14 (refer to Fig. 1) ). Example 2: The solvent absorption step of the above printing test is performed by covering the entirety of the solvent absorber 6 with the vacuum chamber 18 so that the degree of vacuum in the vacuum chamber 18 is based on the gauge pressure. It is calculated as _5kpa(G) and is kept at the specified time (see Figure 3). Example 3: The solvent evaporation removal step of the above-described printing test was carried out by spraying a warm air of 120 ° C from the warm air nozzle 28 while moving the endless belt 27 of the solvent absorber at a speed of 5 mm/s. (Refer to Figure 5). Further, the annular belt 27 is cooled by the respective rollers 29 to 31 with a cooler, and the change in the surface temperature of the endless belt 27 is adjusted to be within /3 ° C before and after the solvent evaporation removal step. First, Comparative Example 1: The stripe pattern was repeatedly printed in the same manner as the above-described printing test except that the solvent removal step was not performed. The results are shown in Fig. 6. For the first embodiment, the line width variation of the stripe pattern can be controlled within ±3 μm, and the line width deviation of the stripe pattern in the substrate 5 can be controlled within ±3 μm. Also, the time required for the suction nozzle to perform suction is 2 seconds on average. For the second embodiment, the line width variation control of the stripe pattern can be controlled within the range of ±3 μm, and the line width deviation of the stripe pattern in the substrate 5 can be controlled within ±4 μm. Further, the time required for the solvent suction treatment in the vacuum chamber 18 is 30 seconds on average. Further, with the third embodiment, the line width variation of the stripe pattern can be controlled to ±fine (four), and the line width deviation of the substrate 5_streak pattern can be controlled. Also, the warm air injection time from the warm air nozzle 28 is 30 seconds on average. As a result of the above-described only examples 1 to 3, it is extremely excellent in that the printing precision required for precision printing, such as a color filter layer of a liquid crystal color filter, is sufficiently exceeded. Further, the measurement of the printing line width is an average value of the values measured at five points in the plane of the substrate 5 (printed body) per printed sheet. The printing of the color filter layer of the liquid crystal color filter requires that the variation of the printing line width be within ±5 m. Further, the deviation of the pattern line width is judged by the value measured at five points in the plane of the substrate 5 (printed body). If the deviation of these values is within 5 则, it is acceptable. Further, the time required for the treatment for removing the solvent from the solvent absorber 6 is counted in such a manner that the time-dependent change in the line width of the pattern is constant. On the other hand, in the case of the comparative example, when the printing line width is less than 7 〇μηι, ink transfer from the blanket 2 to the substrate 5 is poor. Further, in Comparative Example 1, the printing process was stopped at the time when the transfer was poor.
