  Printing has been applied from the field of publishing, which prints characters and images on paper, to the field of electronics, where wiring and resistors are formed, and miniaturization and high quality are required. Among them, a reverse printing method has been proposed as a method for realizing fine patterning (Patent Document 1).

  However, the reversal printing method as shown in FIG. 1 has a problem that alignment is difficult even though a fine pattern can be formed. For example, in FIG. 1, a convex pattern 9 a made of a negative pattern of an alignment mark is provided on the removal plate 4, an alignment mark 9 b is provided on the substrate 5, and the alignment marks 9 a and 9 b are fixed. Observation is performed by the cameras 8a and 8b. Then, by trial printing, the alignment mark 9a of the removal plate is printed on the substrate to be printed, the relative positions of the ink pattern corresponding to the alignment mark 9a and the alignment pattern 9b on the substrate to be printed are obtained, and two fixed units are fixed. Using the cameras 8a and 8b, at least one of the removal plate 4 or the base material 5 is moved to perform alignment.

  However, the above-described alignment method has two transfer steps in which the image information on the relief printing plate is transferred to the blanket after the alignment, and the image information is copied from the blanket to the substrate. Here, since the transfer process provides an opportunity for displacement, precise alignment has been difficult. In the apparatus shown in FIG. 1, the positional accuracy of the obtained ink pattern on the substrate was about ± 30 μm.

  In order to solve the above-mentioned problem, the invention according to claim 1 is a method for producing a printed matter in which an ink pattern is formed at a predetermined location on a base material, the step of providing ink on a blanket, and a convex pattern. Removing a portion of the ink on the blanket that is in contact with the convex pattern and forming an ink pattern on the blanket by bringing the relief plate having the blanket into contact with the blanket; and an ink pattern on the blanket And observing the mark on the substrate with the camera, and the position information of the ink pattern on the blanket and the position information of the mark on the substrate obtained by the two cameras, Determining the relative positions of the ink pattern and the mark on the substrate, aligning the blanket and the substrate, An ink pattern on Tsu preparative transferred into contact with the predetermined portion of the substrate, and a manufacturing method of the printed matter characterized in that it comprises a step of forming an ink pattern on the substrate.

  According to a second aspect of the present invention, there is provided a printed matter manufacturing method according to the first aspect, wherein the relief printing plate has a rotatable cylindrical shape.

  Further, according to a third aspect of the present invention, the blanket is fixed on a cylinder or has a cylindrical shape, and the substrate can be wound in a web shape. An ink pattern is formed on the printed material according to claim 1 or claim 2.

  According to a fourth aspect of the present invention, the step of positioning the blanket and the base material is performed after forming an ink pattern on the base material, and intermittently on the base material by a roll-to-roll method. An ink pattern is formed on the printed material according to claim 3.

  According to a fifth aspect of the present invention, the step of aligning the blanket and the base material is performed during an operation of forming an ink pattern on the base material, and is continuously performed by a roll-to-roll method. An ink pattern is formed on the material. The method for producing a printed matter according to claim 3.

  The invention according to claim 6 is the method for producing a printed matter according to any one of claims 1 to 5, wherein the blanket is a rigid blanket made of a metal material or an inorganic material.

  The invention according to claim 7 is characterized in that the blanket has a silane coupling agent immobilized on a rigid blanket surface made of a metal material or an inorganic material. It was set as the manufacturing method of the printed matter of description.

  In the method for producing a printed matter of the present invention, by observing and aligning the ink pattern before the actual contact with the mark on the substrate with a camera, the transfer process after the alignment is one time, That is, since the opportunity for positional deviation is one time, an ink pattern can be provided at a predetermined position on the substrate with high accuracy, and a high-definition printed matter can be obtained.

  In addition, by making the letterpress plate into a rotatable cylindrical shape, the ink on the blanket can be easily patterned by the rotation operation of the letterpress.

  In addition, by fixing the blanket on the cylinder and allowing the substrate to be wound in a web shape, the movement of the substrate and the blanket is simplified, and observation with a fixed camera becomes easy.

  In addition, when producing printed materials by the roll-to-roll method, it is possible to form ink patterns continuously by performing alignment during printing, and it is possible to produce printed materials with high throughput. became.

  Further, by using a rigid blanket made of an inorganic material such as a metal material or glass as the blanket, the adhesion between the base material and the blanket was weakened, and the base material position could be easily adjusted.

  In addition, by immobilizing a silane coupling agent on the surface of an inorganic material such as a metal material or glass as a blanket, it is possible to improve the releasability of the ink to the blanket when the ink pattern on the blanket is transferred onto the substrate. did it.

  In the present invention, using the ink pattern on the blanket patterned by the relief printing plate and the mark on the substrate, the transfer position of the ink pattern on the blanket onto the substrate is determined and transferred. Features. That is, the alignment is performed using a blanket-like ink pattern and a mark on the substrate in alignment when forming an ink pattern at a predetermined location on the substrate.

  FIG. 2 is an explanatory view of a method for producing a printed material by the reverse printing method of the present invention. (A1), (a2), (a3) are explanatory diagrams of the blanket surface, (b1) is an explanatory diagram of the letterpress, and (c1), (c2) are explanatory diagrams of the substrate surface.

  In FIG. 2 (a1), ink 11 is applied to the surface of the blanket 10 by an ink application device. FIG. 2 (b) shows the relief 12 and has a convex pattern 13. By pressing the relief plate 12 shown in FIG. 2 (b) against the blanket surface 10 shown in FIG. 2 (a1), the portion of the ink on the blanket that is in contact with the projection pattern becomes the convex pattern of the relief plate. The ink on the blanket is patterned as shown in FIG. 2 (a2).

  On the other hand, FIG. 2 (c 1) shows a base material 14 having a mark 15. The blanket 10 having the ink 11 patterned by the relief plate 12 shown in FIG. 2 (a2) comes into contact with the base material 14 shown in FIG. 2 (c1) and transfers the ink. Then, the ink pattern 11 is formed on the substrate 14 as shown in FIG. FIG. 2A3 shows a blanket after the ink 11 is transferred to the base material 14.

  In the present invention, the ink pattern on the blanket 10 shown in FIG. 2 (a2) is observed with a camera, and the mark on the substrate 14 shown in FIG. 2 (c1) is observed with a camera. Then, the relative position of the mark on the substrate is obtained, the contact position of the blanket and the substrate is determined, and after the determination, the blanket and the substrate are brought into contact, and the ink pattern on the blanket is transferred to the substrate. At this time, the two cameras are fixed, and the images obtained from the two cameras, the contact positions of the blanket and the base material are obtained in advance by performing test printing which is test printing. Then, the blanket or the base material is aligned based on the relationship between the images obtained from the two cameras obtained by the trial printing and the contact position between the blanket and the base material. The alignment may be simpler by adjusting the position of the substrate.

  It is the same as the prior art that the alignment of the blanket and the substrate is performed based on the displacement of the alignment mark due to the trial printing. However, the present invention is different from the conventional one in that the three ink patterns are directly observed with a camera. Thereby, precise alignment can be performed without being affected by subtle deviation between the blanket and the letterpress. In FIG. 2, alignment is performed so that the ink pattern 11 on the blanket 10 comes to the center of the cross-shaped mark 15 on the substrate 14.

  A part of the ink pattern on the blanket is only required to be observed with a camera as an image pattern, and a desired ink pattern provided on the substrate may be used, or may be designed as an alignment mark. In addition, the mark on the substrate needs to be provided on the substrate in advance before printing. However, the mark may use a part of the pattern on the substrate or may serve as an alignment mark. It may be provided on the material.

  Next, a printing apparatus used in the method for producing a printed material according to the present invention will be described. FIG. 3 shows a schematic diagram of a printing apparatus in the method for producing a printed material of the present invention. In FIG. 3, a blanket 20 is fixed on a cylinder 21 and an ink application device 22 is provided. In addition, a relief plate 24 for patterning the ink 23 is provided. Further, the base material 25 is drawn out from the winding roll 28, passes through the impression cylinder 26, and is wound up by the winding roll 29. The printing apparatus also includes a camera 31 for observing the ink pattern 23 on the blanket 20 and a camera 32 for observing the mark 33 on the substrate 25. Further, the relief plate 24 is provided with a cleaning unit 27.

  The printing method of the present invention will be described with reference to FIG. First, the ink 23 is supplied from the ink application device 22 to the blanket 20 fixed to the cylinder 21, and the ink 23 is formed on the cylinder 21. When the ink on the blanket 20 is brought into contact with the relief plate 24, unnecessary portions are removed, and an ink pattern 23 is formed on the blanket 20. Then, the ink pattern 23 on the blanket 20 is transferred to the substrate 25. The base material 25 has a web shape, is drawn out from the take-up roll 28, is taken up by the take-up roll 29, and the base material 25 and the blanket 20 are brought into contact by the impression cylinder 26.

  At this time, the ink pattern 23 on the blanket 20 is observed by the camera 31, and the mark 33 on the substrate is observed by the camera 32, and the positional information of the ink pattern on the blanket obtained by the two cameras 31, 32. The relative position between the ink pattern on the blanket and the mark on the substrate is obtained from the position information of the mark on the substrate, and the blanket and the substrate are aligned.

  In FIG. 3, the blanket and the base material are aligned by finely adjusting the contact position of the base material 25 with the blanket 20 as necessary. For fine adjustment of the contact position between the substrate 25 and the blanket 20, the tension of the substrate between the unwinding roll 28 and the impression cylinder 26, or a roll (not shown) placed between the unwinding roll 28 and the impression cylinder 26. This is performed in the longitudinal direction of the base material 25 by adjusting the tension of the base material between them. Moreover, it is performed about the short direction of the base material 25 by the movement of the impression cylinder 26 in the axial direction.

  In the printing apparatus of the present invention shown in FIG. 3, the base material 25 has a web shape, the blanket 20 is fixed on the cylinder 21, and the letterpress has a cylindrical shape that can rotate, and a roll-to-roll system. As a result, an ink pattern is formed on the substrate 25. In the present invention, the blanket may be flat and the relief may be cylindrical, or the blanket may be fixed on the cylinder and the relief may be flat, as shown in FIG. As described above, by adopting the roll-to-roll system as the printing apparatus, the movement is a simple structure including only the rotation mechanism, and the cameras 31 and 32 are easily installed. When the relief plate has a flat plate shape, it is necessary to reciprocate the relief plate with good timing, which complicates the mechanism.

  In addition, by producing a printed material on a web-like substrate by a roll-to-roll method, it is possible to continuously form a pattern made of ink on the substrate, improving productivity and manufacturing cost. Can be suppressed.

  Hereinafter, each mechanism will be described with reference to FIG.

  As the blanket 20, either an elastic blanket or a rigid blanket can be used. The word blanket originally means a blanket or something wrapped like a blanket and means a rubbery part formed on a cylinder. However, in the present invention, in the reversal printing method, a temporary holder for forming an ink layer, removing unnecessary portions with a relief printing plate, and transferring the resulting pattern to a substrate is called a blanket.

  The elastic blanket is fixed on the cylinder 21. In the elastic blanket, a cushion layer softer than the elastic blanket may be provided between the blanket 20 and the cylinder 21. Silicone rubber can be suitably used as the elastic blanket forming material. As a method for fixing the elastic blanket to the cylinder, a method of applying silicone rubber to the metal cylinder 21 and drying it, or a method of attaching a silicone rubber sheet on the cylinder can be used.

  On the other hand, an inorganic material such as a metal material or glass can be used as the rigid blanket forming material. Alternatively, a surface of an inorganic material such as a metal material or glass may be surface-treated using a silane coupling agent, and the surface of the inorganic material such as the metal material or glass may be immobilized.

  Examples of the silane coupling agent include trimethoxysilanes and triethoxysilanes. As one site of the silane coupling agent, a reactive group with an organic compound such as a vinyl group, an epoxy group, an amino group, a methacryl group, or a mercapto group can be selected. In addition, an alkyl group, a group in which a fluorine atom is partially substituted, or a substituent capable of forming a surface with a small surface energy by bonding with siloxane can be selected. When a silane coupling agent having a reactive group is used, after the surface of the glass substrate is treated with the silane coupling agent, other monomer components may be applied and bonded so as to have a predetermined surface free energy. good. Examples of the silane coupling agent having a reactive group include vinyl methoxy silane, vinyl ethoxy silane, p-styryl trimethoxy silane, 3-glycidoxy propyl trimethoxy silane, 2- (3,4 epoxy cyclohexyl) ethyl trimethoxy silane. , 3-methacryloxypropylmethyldiethoxysilane, 3-acryloxypropyltrimethoxysilane, etc., and monomers include styrene, ethylene glycol diglycidyl ether, trimethylpropane triglycidyl ether, lauryl acrylate, dipentaerythritol Hexaacrylate or the like can be used. As the silane coupling agent having no reactive group, methyltrimethoxysilane, n-hexyltrimethoxysilane, n-octyltrimethoxysilane, dodecyltrimethoxysilane and the like can be used. However, it is not limited to an alkyl group.

  The silane coupling agent can be immobilized on the cylinder surface by a method of applying on a metal cylinder or a method of forming a glass film on the surface of a metallic cylinder and further applying a silane coupling agent. . Specifically, a method of applying a silane coupling agent to water, acetic acid water, a water-alcohol mixed solution, or a solution diluted with an alcohol solution on the surface using an applicator method or the like and drying the solution is used. Can do.

  As the ink application device 22 for applying the ink 23 onto the blanket 20, a known device can be used, and specifically, a die coating method, a cap coating method, a roll coating method, an applicator method, a spray coating method, or the like is used. be able to.

  Further, it is desirable that a drying process is performed before the ink 23 on the blanket 20 comes into contact with the relief plate 24. The purpose of the drying process is to increase the viscosity, thixotropy and brittleness of the ink 23. By making the ink 23 on the blanket 20 into a semi-dried state before coming into contact with the relief plate 24, the ink can be accurately patterned by the relief plate 24. However, when the ink 3 is completely dried on the blanket 20, the ink remains on the blanket when the unnecessary ink is removed by the relief printing plate 24 and the ink pattern is transferred from the blanket to the substrate. Therefore, the ink needs to be in a semi-dry state. As the drying step, known methods such as a natural drying method, a cold air drying method / a warm air drying method, a microwave drying method, a reduced pressure drying method, and a radiation drying method such as an ultraviolet ray or an electron beam can be used.

As the relief plate 24, either a rigid relief plate or an elastic relief plate can be used. As the rigid relief plate, one obtained by processing the surface of a metal plate or metal roll, or one obtained by forming a glass film on the metal surface and processing the glass film to form a convex pattern can be used.
Moreover, as an elastic letterpress, a resin letterpress can be used, from resin materials such as nylon, acrylic, silicone resin, styrene-diene copolymer, and rubber materials such as ethylene-propylene-based, butyl-based, and urethane-based rubber. Resin letterpress for flexographic printing and flexographic printing can be used.

  As a method for producing the resin relief plate, a method of pouring resin into a mold, a method of engraving, and the like can be used. Moreover, a highly accurate thing can be produced by forming a convex part by the photolithographic method using photosensitive resin.

  The relief printing plate is used as a cylindrical relief plate by being mounted on the cylindrical plate cylinder 22. At this time, a cushion layer softer than the relief printing plate is provided between the relief printing plate and the cylindrical printing drum 22. You may do it. Moreover, you may use what formed the convex part pattern directly on the plate cylinder.

  In the present invention, either a rigid blanket or an elastic blanket can be used as the blanket, and either a rigid relief plate or an elastic relief plate can be used as the relief plate. When an elastic blanket is used, it is preferable to use a rigid relief plate. On the other hand, when a rigid blanket is used, it is preferred to use an elastic relief plate.

  As the cleaning unit 27 for removing the ink on the convex pattern of the relief plate, a cleaning sheet 30 is used, and a method of removing the ink by bringing the cleaning sheet into contact with the convex pattern can be used. At this time, as shown in FIG. 4, the ink can be continuously removed by employing a roll-to-roll cleaning sheet.

  As the cleaning sheet 30, an adhesive film can be used, and specifically, an adhesive film made of acrylic, olefin, polyurethane, silicone, synthetic rubber or the like can be used. In addition to the adhesive film, a cloth containing a solvent can be used as the cleaning sheet.

  In the present invention, known roll-out rolls 28, roll-up rolls 29, and impression cylinders 26 for the web-like substrate 25 can be used. Moreover, after the image pattern which consists of ink is formed on the base material 25, before winding up with the winding roll 29, a drying process is provided as needed. As the drying step, known methods such as a natural drying method, a cold air drying method / a warm air drying method, a microwave drying method, a reduced pressure drying method, and a radiation drying method such as an ultraviolet ray or an electron beam can be used.

  The cylinder 21 to which the blanket 20 is fixed is controlled with the same gear ratio as the diameter ratio with the relief printing plate, so that there is no slip at the contact portion. It is desirable that the cleaning unit be moved at the same speed as the letterpress when contacting the adhesive substrate, and at a different speed when wiping with a cloth containing a solvent.

  In the present invention, the camera 31 for observing the ink pattern on the blanket and the camera for observing the mark 33 on the substrate can use known ones, and obtain positional information of the ink pattern on the blanket and the mark on the substrate. be able to. The camera is connected to a computer having an image processing function, and the relative position between the ink pattern and the mark can be automatically obtained from the ink pattern on the blanket obtained from the camera and the position information on the mark on the substrate. Further, when the computer is connected to the control function of the printing apparatus, the position of the obtained ink pattern and the position of the mark are misaligned, and the contact position between the substrate 25 and the blanket 20 needs to be finely adjusted. In addition, the position of the plate cylinder 26 of the base material, the brake of the unwinding roll 28, and the like can be automatically adjusted.

  In addition, the movement of the cylinder 21, the relief plate 24, the impression cylinder 26, etc. is preferably performed intermittently when positioning accuracy is important. Each time the relief printing plate 24 makes one rotation, it is temporarily stopped, and in this state, alignment marks are observed and the base material 25 is aligned. On the other hand, continuous operation is desirable when alignment accuracy is not very important. The observation image of the alignment mark is captured by the camera, quickly analyzed, and the base material 25 is aligned during the rotation operation.

  Further, since it is necessary to slightly shift the substrate 25 from the blanket 20, it is more desirable that the blanket 20 is a rigid blanket and the surface of the impression cylinder 6 is made of an elastic body.

  Ink materials used in the present invention are generally organic ink materials as well as other metal fine particle dispersions such as gold, silver, copper, nickel, platinum, palladium, rhodium, and various additives as required. Can be used. At this time, water, alcohol, an organic solvent, or the like can be used as the dispersion medium.

  As the base material used in the present invention, a web-like film base material that can be wound can be suitably used. As the material, polyethylene terephthalate, polyethylene naphthalate, polyethersulfone, cycloolefin polymer, polyimide, Nylon, aramid, polycarbonate, polymethyl methacrylate, polyvinyl chloride, triacetyl cellulose, or the like can be used. Among these, heat-resistant polyethylene naphthalate, polyether sulfone, cycloolefin polymer, polyimide and the like are preferable. Moreover, the thing which added the inorganic filler to the said resin and improved heat resistance may be used. The film may be stretched or unstretched. Moreover, the gas barrier layer, the smoothing layer, and the sliding layer may be laminated | stacked on the base film as needed. In the present invention, it is possible to use glass or a metal plate as the base material, but in this case, the printing apparatus needs to be a sheet-fed system.

  First, the printing apparatus will be described with reference to FIG. As the blanket 20, a steel cylinder 21 plated with copper, surface-polished, and treated with a silane coupling agent is used. The relief printing plate 24 has a resin relief printing plate prepared separately on an iron cylinder plated with copper. As the ink application device 22, a blade type was used. Commercially available products were used for the impression cylinder 26, the unwinding roll 28, the winding roll 29, and the impression cylinder, the unwinding roll, and the winding roll of the cleaning unit 27. As the cleaning sheet, a non-woven fabric containing a small amount of a solvent was used.

  Next, actual printing will be described. For the ink, a conductive ink made of a silver particle aqueous dispersion having a volume average particle diameter (Dv) of 20 nm was used.

  Polyethylene naphthalate (PEN) film was used for the substrate 25. The ink was applied on the blanket 20 by the supply unit 22 and pre-dried at about 60 ° C. by an infrared unit (not shown). The ink 23 thus formed was in contact with the relief plate 24 to remove the portion to be removed. The ink pattern 23 on the blanket 20 was observed with the camera 31, and at the same time, the mark 33 provided in advance on the substrate 25 was observed with the camera 32.

  Then, the position of the ink pattern 23 on the blanket where the blanket 20 and the substrate 26 are in contact with the impression cylinder 26 and the position of the mark 33 on the substrate are checked, and the relative position on the screen of the ink pattern 23 and the mark 33 is determined. I investigated what should be done.

  After adjusting the position of the impression cylinder 26 and the brake of the unwinding roll 28 to optimum values, automatic operation was started. Intermittent operation in which the printing plate 24 is temporarily stopped each time it rotates once, the ink pattern 23 and the mark 33 are observed, the position of the impression cylinder 26 and the brake of the unwinding roll 28 are automatically adjusted, and transferred to the substrate 25. Went. The printed substrate 25 was dried by a drying unit (not shown) and then wound up by a winding roll 29. The printed matter thus obtained had a positioning accuracy within ± 10 μm, and a highly accurate printed matter could be obtained.

  Printing similar to that in Example 1 was performed by rotating the blanket 20, the relief plate 24, the impression cylinder 26, the unwinding roll 28, the winding roll 29, etc. at a constant speed. At this time, the camera image observing the ink pattern 23 on the blanket and the mark 33 on the substrate was simultaneously captured, processed by a high speed computer, and fed forward to the position of the impression cylinder 26 and the brake of the unwinding roll 28. . In this method, since the alignment mark image was blurred, the alignment accuracy fell to ± 20 μm, but printing could be performed at a higher speed than in Example 1.
