  By the way, in the resin-molded body film decoration method described in Patent Document 1 described above, for example, when a thin film such as a decorative print layer is transferred from a film to a transfer target, the thin film transferred to the transfer target There is room for further improvement in terms of glossiness.

  The present invention has been made in view of the above circumstances, and provides a method for manufacturing a transfer body, an inkjet printer, a transfer film, and a transfer body that can improve the glossiness of a thin film transferred to the transfer body. The purpose is to provide.

  In order to achieve the above object, the method for producing a transfer medium according to the present invention is such that a thin film provided in contact with a sheet-like base material constituting a transfer film is in contact with a surface opposite to the base material. A smooth layer printing step of printing a smooth layer, an adhesive layer printing step of printing an adhesive layer so as to contact a surface of the smooth layer opposite to the thin film, or a transfer target surface of the transfer target, A transfer step of transferring the thin film to the transfer surface by laminating and pressing the transfer object and the transfer film so that the adhesive layer is interposed between the transfer surface and the smooth layer; After the transfer step, the method includes a peeling step of peeling the base material and the thin film, wherein the smooth layer has a higher hardness than the adhesive layer.

  Thereby, since the transferred body manufactured by the transferred body manufacturing method can reduce unevenness on the surface of the thin film by interposing a smooth layer having high hardness between the thin film and the adhesive layer, The glossiness of the thin film transferred to the transfer target can be improved.

  In the method for producing a transfer medium, in the smooth layer printing step, at least the smooth layer ink that is the ink that forms the smooth layer and the degree of cure of which changes when exposed is changed to the base of the thin film. A first layer printing step of printing the first layer by discharging to the surface opposite to the material and then exposing the smooth layer ink to a main curing state by exposing to the smooth layer ink; and an ink for forming the smooth layer Is ejected onto the surface of the first layer opposite to the thin film, and the ink is stored in a concave / convex recess formed on the surface of the first layer opposite to the thin film. And a second layer printing step of printing a second layer for smoothing the surface opposite to the thin film.

  As a result, the transferred object manufactured by the transferred object manufacturing method is formed by the ink forming the second layer entering the unevenness that may occur on the surface of the first layer by the main curing of the first layer. The surface of the first layer can be leveled (leveled) by the second layer. As a result, since the transfer object can improve the smoothness of the smooth layer itself, the gloss of the thin film transferred to the transfer object can be further improved.

  Further, in the second layer printing step of the transfer object manufacturing method, the smooth layer ink that is the ink that forms the smooth layer and the degree of curing of which changes when exposed is changed to the smooth layer ink of the first layer. The second layer is printed by discharging to the surface opposite to the thin film and then exposing the smooth layer ink to a pre-cured state having a lower curing degree than the main cured state. be able to.

  Accordingly, the transfer object manufactured by the transfer object manufacturing method can form the second layer with the ink common to the ink forming the first layer, and the second layer can be formed in a relatively short time. Since a layer can be formed, manufacturing efficiency can be improved.

  Further, in the adhesive layer printing step of the transfer object manufacturing method, the adhesive layer ink which is the ink for forming the adhesive layer and whose degree of curing is changed by exposure is referred to as the thin film of the smooth layer. The adhesive layer is printed by exposing it to the opposite surface or the surface to be transferred and then exposing the adhesive layer ink to a temporarily cured state having a lower degree of cure than the main cured state. Furthermore, at least after the transfer step, the adhesive layer and the second layer of the smooth layer are exposed to the second layer of the smooth layer by exposing the adhesive layer and the second layer of the smooth layer to a state of main curing. It may include an irradiation step of curing.

  As a result, the transferred object manufactured by the transferred object manufacturing method is subjected to an irradiation process for permanently curing the adhesive layer and the like after the transfer process, so that the thin film can be transferred to the transferred surface while the adhesive layer is temporarily cured. Since the adhesive layer can be fully cured after being transferred to the film, the thin film and the transfer surface can be securely bonded.

  In order to achieve the above object, an ink jet printer according to the present invention includes a smooth layer ink tank that stores a smooth layer ink that is an ink that forms a smooth layer and has a degree of curing that changes when exposed. An adhesive layer ink tank that stores an adhesive layer ink that is an ink that forms a layer and has a degree of curing that is changed by exposure; the smooth layer ink that is stored in the smooth layer ink tank; and the adhesive A discharge unit capable of discharging the adhesive layer ink stored in a layer ink tank, the smooth layer ink discharged from the discharge unit, and an exposure unit capable of exposing the adhesive layer ink; A smoothing layer ink stored in the smoothing layer ink tank by the discharging unit. The thin film provided in contact with the sheet-like base material constituting the transfer film is cured by being exposed to the smooth layer ink by the exposure unit after being discharged onto the surface opposite to the base material. In the control for printing the smooth layer, the surface of the smooth layer opposite to the thin film, or the transfer surface of the transfer body, the adhesive layer ink stored in the adhesive layer ink tank by the discharge unit After printing on the surface to be transferred, and after the thin film is transferred to the transfer surface The adhesive layer can be controlled to be fully cured by exposing the adhesive layer to the exposure unit, and the smooth layer has a higher hardness than the adhesive layer. It is characterized in.

  As a result, the transferred object on which each layer is printed by the ink jet printer can reduce unevenness on the surface of the thin film by interposing a smooth layer having high hardness between the thin film and the adhesive layer. The glossiness of the thin film transferred to the transfer target can be improved.

  Further, in the ink jet printer, the control device discharges the smooth layer ink stored in the smooth layer ink tank by the discharge unit onto the surface of the thin film opposite to the base material, and then exposes the exposure unit. The first layer of the smooth layer is printed by being cured to the main curing state by exposing the smooth layer ink to the ink for forming the smooth layer by the discharge unit. The ink is ejected onto the surface opposite to the thin film, and the ink is stored in an uneven recess formed on the surface of the first layer opposite to the thin film, opposite to the thin film of the first layer. Control for printing the second layer of the smoothing layer for smoothing the side surface can be executed.

  As a result, the transferred object on which each layer is printed by the ink jet printer has the ink that forms the second layer entering the unevenness that may be generated on the surface of the first layer by the main curing of the first layer. The surface of the first layer can be leveled (leveled) by the second layer. As a result, since the transfer object can improve the smoothness of the smooth layer itself, the gloss of the thin film transferred to the transfer object can be further improved.

  In the ink jet printer, the control device prints the smooth layer ink stored in the smooth layer ink tank by the discharge unit as the control for printing the second layer of the smooth layer. After discharging to the surface opposite to the thin film, the smoothing layer ink is exposed to the smoothing layer ink by the exposure unit to be cured to a temporary curing state having a lower curing degree than the main curing state. It is possible to execute control for printing two layers. Further, after the thin film is transferred to the transfer surface, the second layer is exposed to the second layer by exposing the second layer by the exposure unit. Control to cure to a state can be feasible.

  As a result, the transfer medium on which each layer is printed by the ink jet printer can form the second layer with the ink common to the ink forming the first layer, and the second layer can be formed in a relatively short time. Therefore, manufacturing efficiency can be improved.

  In order to achieve the above object, a transfer film according to the present invention is provided in contact with a sheet-like base material, a thin film provided in contact with the base material, and a surface of the thin film opposite to the base material. And an adhesive layer provided in contact with the surface of the smooth layer opposite to the thin film, wherein the smooth layer has a higher hardness than the adhesive layer.

  Thereby, since the smooth body having a high hardness is interposed between the thin film and the adhesive layer, the transferred object having the thin film transferred from the transfer film can reduce the unevenness on the surface of the thin film. The glossiness of the thin film transferred to the transfer target can be improved.

  Further, in the transfer film, the smooth layer may include at least the smooth layer ink that forms the smooth layer, and the smooth layer ink that changes in a degree of curing when exposed to light. A first layer cured to a main curing state by being exposed to the smooth layer ink after being discharged onto the surface opposite to the material, and the thin layer of the first layer containing the ink that forms the smooth layer The ink is ejected onto the surface opposite to the first layer, and the ink is accommodated in a concave / convex recess formed on the surface opposite to the first layer of the thin film, so that it is opposite to the first layer of the thin film. And a second layer that smoothes the side surface.

  As a result, the transferred material onto which the thin film has been transferred from the transfer film has the ink that forms the second layer entering the unevenness that may be generated on the surface of the first layer by the main curing of the first layer, The surface of the first layer can be leveled (leveled) by the second layer. As a result, since the transfer object can improve the smoothness of the smooth layer itself, the gloss of the thin film transferred to the transfer object can be further improved.

  In the transfer film, the second layer is formed by discharging the smooth layer ink onto a surface of the first layer opposite to the thin film and then exposing the smooth layer ink to the main layer. It can be a layer cured to a temporarily cured state having a lower degree of curing than the state.

  As a result, the transfer object to which the thin film is transferred from the transfer film can form the second layer with the ink common to the ink forming the first layer, and the second layer can be formed in a relatively short time. Since it can form, manufacturing efficiency can be improved.

  In order to achieve the above-mentioned object, a transfer object according to the present invention includes an adhesive layer provided in contact with a transfer surface, and a smooth layer provided in contact with a surface of the adhesive layer opposite to the transfer surface. And a thin film provided in contact with the surface of the smooth layer opposite to the adhesive layer, wherein the smooth layer has a higher hardness than the adhesive layer.

  As a result, since the smooth body having a high hardness is interposed between the thin film and the adhesive layer, the transferred object can reduce irregularities on the surface of the thin film. Glossiness can be improved.

  Embodiments according to the present invention will be described below in detail with reference to the drawings. In addition, this invention is not limited by this embodiment. In addition, constituent elements in the following embodiments include those that can be easily replaced by those skilled in the art or those that are substantially the same.

[Embodiment]
FIG. 1 is a schematic cross-sectional view illustrating a schematic configuration of a transfer film according to an embodiment.

  The transfer film 1 of the present embodiment shown in FIG. 1 is transferred to the thin film 3 formed in a desired figure (characters, patterns, etc.) by being superimposed on the transfer surface 51 of the transfer object 50 and pressed. It can be transferred to the surface 51. The transferred object 50 can be, for example, a three-dimensional object such as a portable cover, a bottle, or a container, but is not limited to this, and objects of various shapes and materials can be applied. Typically, the transfer surface 51 of the transfer object 50 is preferably formed of a material or the like in which UV (ultraviolet) curable ink, which will be described later, hardly permeates. The transfer surface 51 of the transfer object 50 is not limited to a flat surface but may be a curved surface.

  And the transfer film 1 of this embodiment improves the glossiness (glossiness) of the thin film 3 transferred to the transfer target 50 by interposing the smooth layer 4 between the thin film 3 and the adhesive layer 5. I am trying.

  Specifically, the transfer film 1 includes a base material 2, a thin film 3, a smooth layer 4, and an adhesive layer 5. The transfer film 1 has a layer structure in which the substrate 2, the thin film 3, the smooth layer 4, and the adhesive layer 5 are in contact with each other in this order from the substrate 2 side.

  The base material 2 is a sheet-like member, and is a base member for forming and holding the thin film 3 before transfer. Although the base material 2 is comprised with the film which has flexibility, for example, it is not restricted to this. As the substrate 2, for example, a film that transmits ultraviolet rays, such as a PET film, can be suitably used.

  The thin film 3 is a layer that can be transferred to the transfer target 50 and is provided in contact with the substrate 2. Typically, the thin film 3 is preferably a film that reflects light well. Although the thin film 3 is comprised by the metal vapor deposition film vapor-deposited on the base material 2, for example, it is not restricted to this. As the thin film 3, for example, a vapor deposition film such as gold or silver having high gloss can be suitably used. The thin film 3 may be a thin film for a hologram film, for example, instead of a metal vapor deposition film. Moreover, the thin film 3 may include a release layer for facilitating the peeling of the thin film 3 and the base material 2 on the contact surface with the base material 2.

  The smooth layer 4 is provided in contact with the surface of the thin film 3 opposite to the base 2. The smooth layer 4 of the present embodiment is printed so as to be in contact with the surface of the thin film 3 opposite to the base 2 and is provided in contact with the thin film 3. The smooth layer 4 functions as a base layer and a leveling layer when the thin film 3 is transferred to the transfer surface 51. The smooth layer 4 is typically formed of ink whose degree of cure changes when exposed to light, in this case, UV (ultraviolet) curable ink that cures when irradiated with ultraviolet rays. In the following description, the ink forming the smooth layer 4 may be referred to as “smooth layer ink”.

  As the smooth layer 4 of this embodiment, a layer having a higher hardness than the adhesive layer 5 is used. Here, the hardness is a scale representing the degree of hardness of a substance. As the smooth layer 4, a material having a hardness higher than that of the adhesive layer 5 in a fully cured state in which the smooth layer 4 and an adhesive layer 5 described later are completely cured is used. As the smooth layer 4, for example, a polyfunctional acrylate monomer can be used as one having higher hardness than the adhesive layer 5. As the smooth layer ink forming the smooth layer 4, for example, “LH-100 Clear Liquid (product name)” manufactured by Mimaki Engineering Co., Ltd. can be used. The ink composition of this “LH-100 Clear Liquid” is, for example, acrylic ester (50-60%), hexamethylene diacrylate (30-35%), initiator (for example, diphenyl-2,4,6- Trimethylbenzoylphosphine = oxide (10-15%), additive (0.1-5%) The smooth layer 4 can be printed using various printing methods such as silk printing and ink jet printing. However, here, description will be made assuming that printing is performed by the inkjet printer 100 (see FIG. 3) as described later.

  Here, FIG. 2 is a schematic cross-sectional view showing a partial cross section including the smooth layer according to the embodiment. As illustrated in FIG. 2, the smooth layer 4 of the present embodiment has a multilayer structure including a first layer 41 and a second layer 42 having different degrees of ink curing when printed. preferable. Thereby, the transfer film 1 of this embodiment can aim at the further improvement of the glossiness of the thin film 3. FIG. The smooth layer 4 described below will be described as having a three-layer structure including a third layer 43 in addition to the first layer 41 and the second layer 42. To print the smooth layer 4, the inkjet printer 100 is used. You may change suitably according to the specification (refer FIG. 3), performance, the discharge amount of an ink, the dot diameter of the discharged ink, etc. FIG. That is, in this case, the smooth layer 4 may be configured to include at least the first layer 41 and the second layer 42, and may have a two-layer structure of the first layer 41 and the second layer 42, In addition to the first layer 41, the second layer 42, and the third layer 43, a layer structure of four or more layers including a plurality of layers may be used.

  Specifically, the first layer 41 of the smooth layer 4 is exposed to the smooth layer ink after ejecting the smooth layer ink onto the surface of the thin film 3 opposite to the base 2 (see FIG. 1). Is formed by curing to the state of main curing. On the other hand, the second layer 42 of the smooth layer 4 ejects the ink forming the smooth layer 4 onto the surface of the first layer 41 opposite to the thin film 4, and the ink is separated from the thin film 3 of the first layer 41. It is a layer that is housed in a concave-convex recess formed on the opposite surface and smoothes the opposite surface of the first layer 41 from the thin film 3. Here, the second layer 42 has a lower degree of curing than the state of the main curing by exposing the smooth layer ink to the surface of the first layer 41 opposite to the thin film 3 and then exposing the smooth layer ink. It is formed by curing in a temporarily cured state. Similarly, the third layer 43 of the smooth layer 4 is exposed to the smooth layer ink after the smooth layer ink is ejected to the surface of the second layer 42 opposite to the first layer 41, so that the main curing can be performed. It is formed by curing to a pre-cured state having a lower degree of curing than the state.

  Here, the pre-cured state means, for example, that the ink is brought to a state where the ink has some tackiness by irradiating with UV light having a relatively weak intensity such that the UV curable ink is not completely cured. It is in a semi-cured state. For example, when the intensity of the irradiated ultraviolet light is 100% when the ink is cured to the main curing state, the intensity of the ultraviolet light irradiated when the ink is cured to the temporary curing state is typically 15% to 35%, preferably 20% to 30%, for example, about 23% (hereinafter, the same applies).

  When the smooth layer 4 includes four or more layers, the fourth and subsequent layers may be formed in the same manner as the second layer 42 and the third layer 43. The reason why the glossiness of the thin film 3 can be further improved by making the smooth layer 4 itself a multilayer structure as described above in the transfer film 1 of the present embodiment will be described in detail later.

  Returning to FIG. 1, the adhesive layer 5 is provided in contact with the surface of the smooth layer 4 opposite to the thin film 3. The adhesive layer 5 of the present embodiment is printed so as to be in contact with the surface of the smooth layer 4 opposite to the thin film 3 and is provided in contact with the smooth layer 4. The adhesive layer 5 functions as an adhesive capable of adhering to the transferred object 50, and adheres the thin film 3 to the transferred surface 51 of the transferred object 50 via the smooth layer 4 or the like. The adhesive layer 5 is typically formed of an ink whose degree of cure changes when exposed to light, here, a UV (ultraviolet) curable ink that cures when irradiated with ultraviolet rays. The adhesive layer 5 is typically formed of ink that retains some tack (tackiness) even when cured to a fully cured state. In the following description, the ink forming the adhesive layer 5 may be referred to as “adhesive layer ink”.

  The adhesive layer 5 of the present embodiment uses a flexible material having a lower hardness than the smooth layer 4. For example, a monofunctional acrylate monomer can be used as the adhesive layer 5 as having a lower hardness than the smooth layer 4 and having flexibility. As the adhesive layer ink for forming the adhesive layer 5, an inkjet UV primer, for example, “IJ Primer PR-100 (product name)” manufactured by Mimaki Engineering Co., Ltd. or the like can be used. The ink composition of “IJ Primer PR-100” is, for example, acrylic ester (80-90%), initiator (5-15%), and additive (0.1-5%). The adhesive layer 5 can be printed using various printing methods such as silk printing and ink jet printing, as with the smooth layer 4, but here it is printed by the ink jet printer 100 (see FIG. 3) as will be described later. It will be described as being done.

  The adhesive layer 5 may be a single layer, but depending on the specifications, performance, ink ejection amount, ink dot diameter of the ejected ink, etc. for printing the adhesive layer 5. A multilayer structure may be used. However, in this case, unlike the smooth layer 4, the adhesive layer 5 does not need to have different degrees of ink curing when printed in each layer.

  In the transfer film 1 configured as described above, the thin film 3 is transferred to the transferred surface 51 by being superimposed so that the adhesive layer 5 is in contact with the transferred surface 51 of the transferred object 50 and pressed from the substrate 2 side. Is transferred to.

  Hereinafter, with reference to FIG. 3 to FIG. 12, the manufacturing method of the transferred object 50 to which the thin film 3 formed in a desired figure (character, pattern, etc.) is transferred, including the manufacturing method of the transfer film 1, will be described in detail. I will explain it.

  The ink tank 102 stores ink to be ejected to a medium (here, the base material 2 of the transfer film 1 or the transfer target 50) M. Here, at least the smooth layer ink tank 105 and the adhesive layer ink tank 106 are stored. It is comprised including. The smooth layer ink tank 105 stores the smooth layer ink (for example, “LH-100 Clear Liquid”) that is the ink that forms the smooth layer 4 and has a degree of curing that changes when exposed. The adhesive layer ink tank 106 stores an adhesive layer ink (for example, “IJ Primer PR-100”) that is an ink that forms the adhesive layer 5 and has a degree of curing that changes when exposed.

  The carriage 103 is movable in the main scanning direction along the Y bar 101. The carriage 103 is controlled to move in a direction (main scanning direction) orthogonal to the printing conveyance direction (sub-scanning direction) of the medium M. The carriage 103 includes a holder 107 and a pair of ultraviolet lamps 108 as exposure units provided on both sides of the holder 107 in the main scanning direction. In the inkjet printer 100, a discharge unit 109 is disposed on a holder 107. The ejection unit 109 applies the smooth layer ink stored in the smooth layer ink tank 105 and the adhesive layer ink stored in the adhesive layer ink tank 106 to the medium M, here, the substrate 2 of the transfer film 1 or the transfer target 50. Can be discharged onto the transfer surface 51. The ejection unit 109 includes, for example, a printer head that ejects ink facing the medium M, various ink channels that connect the ink tank 102 and the printer head, a regulator and a pump that are provided on the ink channel, and the like. Is done. Here, the printer head is configured to include at least a head portion that ejects the smooth layer ink for the smooth layer 4 and a head portion that ejects the adhesive layer ink for the adhesive layer 5. To the smoothing layer ink tank 105 and the adhesive layer ink tank 106. When the pump is driven, the ejection unit 109 performs ink jetting of the smooth layer ink in the smooth layer ink tank 105 and the adhesive layer ink in the adhesive layer ink tank 106 from the respective head units of the printer head toward the medium M with a predetermined ejection amount. It can be discharged by a method. Each of the ultraviolet lamps 108 can be exposed to the medium M, here, the ink ejected onto the substrate 2 of the transfer film 1 and the transfer target surface 51 of the transfer target 50. Each ultraviolet lamp 108 is configured by, for example, an LED module that can irradiate ultraviolet rays. In addition, the inkjet printer 100 includes a transport device that moves the medium M relative to the carriage 103 in the print transport direction (sub-scanning direction) together with a platen, a table, and the like on which the medium M is placed.

  The control device 104 controls each unit of the ink jet printer 100 including the ejection unit 109, each ultraviolet lamp 108, and the like. The control device 104 includes an ejection control unit 104a, an exposure control unit 104b, a pattern conversion unit 104c, and the like in terms of functional concept. The control device 104 includes hardware such as an arithmetic device and a memory, and a program that realizes these predetermined functions. The discharge controller 104a controls the pump and the like of the discharge unit 109, and controls the discharge amount, discharge timing, discharge period, and the like of ink discharged from the discharge unit 109. The exposure control unit 104b controls each ultraviolet lamp 108 and the like, and controls the intensity of the ultraviolet rays irradiated from each ultraviolet lamp 108, the exposure timing, the exposure period, and the like. The pattern conversion unit 104c sets an ejection control amount and an exposure control amount in accordance with input information input from an input device 200 such as a PC or various terminals connected to the control device 104 by wire / wireless. . The pattern conversion unit 104c receives as input information, for example, image information input via the input device 200 or the like and image information of a desired graphic (character, pattern, etc.) to be transferred to the transfer target 50. The Then, the pattern conversion unit 104c can generate the pattern of the smooth layer 4 and the adhesive layer 5 so as to obtain a desired graphic to be transferred to the transfer target 50 based on the input information, and can realize the generated print pattern. To a proper discharge control amount and exposure control amount. The ejection control unit 104a controls ejection by the ejection unit 109 based on the ejection control amount calculated by the pattern conversion unit 104c, and the exposure control unit 104b performs each control based on the exposure control amount calculated by the pattern conversion unit 104c. The exposure by the ultraviolet lamp 108 is controlled.

  In the inkjet printer 100 configured as described above, the ejection unit 109 moves the carriage 103 with respect to the medium M in the main scanning direction while moving the carriage 103 back and forth with respect to the printing surface of the medium M according to control by the control device 104. Ink is ejected at a predetermined printing width. The ink jet printer 100 controls the spread of the ink that has landed on the medium M by irradiating each ultraviolet lamp 108 with a relatively weak ultraviolet ray at a predetermined timing in accordance with control by the control device 104. In addition to performing temporary curing (pinning exposure) to control the dot diameter and the like to suppress bleeding, main curing (curing exposure) is performed to completely cure by irradiating and exposing relatively strong ultraviolet rays. The temporary curing state described above is a state where the ink landed on the medium M is temporarily cured by pinning exposure, while the main curing state is the state where the ink landed on the medium M is fully cured by curing exposure. State. The inkjet printer 100 repeats this while moving the medium M relative to the carriage 103 in the print transport direction (sub-scanning direction) according to the predetermined print width, and prints a predetermined pattern. During this time, the control device 104 controls the ejection amount, ejection timing, ejection period, and the like of the ink ejected from the ejection unit 109 by the ejection control unit 104a, and the intensity and pinning of ultraviolet rays emitted from each ultraviolet lamp 108 by the exposure control unit 104b. / Curing ring exposure timing, pinning / curing exposure period, etc. are controlled.

  In the transferred object manufacturing method of the present embodiment, first, as a thin film forming process, as shown in FIG. 5, the thin film 3 is provided so as to be in contact with the sheet-like substrate 2 (step ST1). The thin film 3 is formed, for example, by depositing a metal film such as gold or silver on the substrate 2. In the transfer object manufacturing method, the thin film forming step (step ST1) may be omitted by using an off-the-shelf product in which the thin film 3 is already deposited on the substrate 2.

  Next, as a smooth layer printing step, the thin film 3 provided in contact with the sheet-like substrate 2 constituting the transfer film 1 (see FIG. 1 and the like) is smoothed so as to contact the surface opposite to the substrate 2. Layer 4 is printed (step ST2 to step ST4). At this time, the inkjet printer 100 prints the smooth layer 4 with the smooth layer ink. In this case, the control device 104 discharges the smooth layer ink stored in the smooth layer ink tank 105 by the discharge unit 109 onto the surface of the thin film 3 opposite to the substrate 2 and then a pair of ultraviolet lamps as an exposure unit. It is possible to execute control to print the smooth layer 4 by curing by exposing the smooth layer ink to 108. The control device 104 controls the discharge amount, discharge timing, discharge period, and the like of the smooth layer ink discharged from the discharge unit 109 by the discharge control unit 104a, and the intensity and pinning of the ultraviolet rays irradiated from each ultraviolet lamp 108 by the exposure control unit 104b. / Curing ring exposure timing, pinning / curing exposure period, etc. are controlled. Thereby, the control apparatus 104 prints the smooth layer 4 so that it may become a desired figure to transfer to the to-be-transferred body 50 according to the printing pattern which the pattern conversion part 104c produced | generated.

  More specifically, the smooth layer printing step (step ST2 to step ST4) of the present embodiment includes a smooth layer first layer printing step (step ST2), a smooth layer second layer printing step (step ST3), and a smooth layer. And a third layer printing step (step ST4).

  Here, as the smooth layer first layer printing step, as shown in FIG. 6, the smooth layer ink is discharged onto the surface of the thin film 3 opposite to the base 2 and then exposed to the smooth layer ink. Thus, the first layer 41 of the smooth layer 4 is printed by being cured to the main curing state (step ST2). In this case, the control device 104 discharges the smooth layer ink stored in the smooth layer ink tank 105 by the discharge unit 109 to the surface of the thin film 3 opposite to the base 2, and then uses the ultraviolet lamp 108 to perform the smooth layer ink. It is possible to execute control to print the first layer 41 of the smooth layer 4 by curing to the state of the main curing by exposing to.

  For example, the control device 104 ejects smooth layer ink from the ejection unit 109 and irradiates relatively strong ultraviolet rays from the ultraviolet lamp 108 in the forward path of movement of the carriage 103 (see FIG. 3) along the main scanning direction. The smoothing layer ink is cured to a main curing state by curing exposure according to the above. For example, the control device 104 performs smoothing by combining the ultraviolet irradiation from the ultraviolet lamp 108 in the forward path and the ultraviolet irradiation from the ultraviolet lamp 108 in the return path (see FIG. 7) accompanying the printing of the second layer 42 described later. The layer ink may be cured to a main curing state.

  Here, the 1st layer 41 of the smooth layer 4 printed and made into the state of this hardening as mentioned above has hardness higher than the below-mentioned contact bonding layer 5. At this time, when the smoothing layer ink forming the first layer 41 is cured to the main curing state, the inkjet printer 100 ejects the smoothing layer ink from the ejection unit 109 to the thin film 3, and the smoothing layer ink is thin film 3. Immediately after landing, curing by ultraviolet irradiation is started. For this reason, the first layer 41 of the smooth layer 4 is cured by ultraviolet irradiation before the dots of the smooth layer ink landed on the thin film 3 are sufficiently spread, and the first layer 41 is fully cured before the ink layer is sufficiently flat. It may be in a state. In this case, the first layer 41 of the smooth layer 4 may be cured to a fully cured state before it becomes sufficiently flat, with minute irregularities remaining on the surface.

  On the other hand, in the transferred object manufacturing method of the present embodiment, after the first layer 41 is printed, the second layer 42 of the smooth layer 4 is further printed on the first layer 41, whereby the smooth layer 4. Form. The second layer 42 is formed by storing the ink that forms the smooth layer 4 in an uneven recess formed on the surface of the first layer 41 opposite to the thin film 3. The surface opposite to the thin film 3 is smoothed. Here, after the first layer 41 is printed, the second layer 42 of the smooth layer 4 is printed by discharging the smooth layer ink onto the first layer 41 and curing the ink in a temporarily cured state. 4 is formed. As a result, the smooth layer 4 is cured relatively slowly after the smooth layer ink forming the second layer 42 has landed on the surface of the first layer 41. As a result, the smooth layer 4 enters the fine irregularities on the surface of the first layer 41, and the smooth layer ink is temporarily cured after the surface of the first layer 41 is leveled (leveled). The second layer 42 is formed by being cured to the state. As described above, the smooth layer 4 is formed as a multilayer structure including at least the first layer 41 and the second layer 42 in which the degree of curing of the inks is different from each other, thereby reducing the smoothness of the smooth layer 4 itself. Can be improved.

  As the smooth layer second layer printing step for forming the second layer 42, as shown in FIG. 7, the ink for forming the smooth layer 4 is ejected to the surface of the first layer 41 opposite to the thin film 3, The ink is stored in a concave / convex recess formed on the surface of the first layer 41 opposite to the thin film 3, and the second layer 42 for smoothing the surface of the first layer 41 opposite to the thin film 3. To print. Here, after the smooth layer ink is ejected onto the surface of the first layer 41 opposite to the thin film 3, the smooth layer ink is exposed to light and cured to a temporarily cured state having a lower degree of curing than the main cured state. Then, the second layer 42 of the smooth layer 4 is printed (step ST3). In this case, the control device 104 ejects ink that forms the smooth layer 4 to the surface of the first layer 41 opposite to the thin film 3 by the ejection unit 109, and the ink is separated from the thin film 3 of the first layer 41. It is possible to execute control for printing the second layer 42 of the smooth layer 4 that is housed in a concave-convex recess formed on the opposite surface and smoothes the opposite surface of the first layer 41 to the thin film. . That is, here, the control device 104 ejects the smooth layer ink stored in the smooth layer ink tank 105 by the ejection unit 109 onto the surface of the first layer 41 opposite to the thin film 3, and then performs the smoothing by the ultraviolet lamp 108. It is possible to execute control to print the second layer 42 of the smooth layer 4 by exposing the layer ink to a temporary curing state having a lower degree of curing than the main curing state. The control device 104, for example, ejects smooth layer ink from the ejection unit 109 and irradiates relatively weak ultraviolet rays from the ultraviolet lamp 108 in the return path of movement of the carriage 103 (see FIG. 3) along the main scanning direction. The smooth layer ink is cured into a temporarily cured state by the pinning exposure according to.

  Here, as a smooth layer third layer printing step for forming the third layer 43 in order to increase the smoothness of the smooth layer 4, as shown in FIG. 8, the smooth layer ink is added to the first layer 41 of the second layer 42. The third layer 43 of the smooth layer 4 is printed by discharging to the opposite surface and then exposing the smooth layer ink to a temporarily cured state having a lower degree of cure than the main cured state ( Step ST4). The control device 104 ejects the smooth layer ink from the ejection unit 109, for example, in the forward path of movement of the carriage 103 (see FIG. 3) along the main scanning direction, in the same manner as in the smooth layer second layer printing step (step ST3). At the same time, the smooth layer ink is cured to a temporarily cured state by pinning exposure by irradiating relatively weak ultraviolet rays from the ultraviolet lamp 108.

  Next, as an adhesive layer printing process, as shown in FIG. 9, the adhesive layer 5 is printed so as to contact the surface of the smooth layer 4 opposite to the thin film 3 (step ST5). At this time, the inkjet printer 100 prints the adhesive layer 5 with the adhesive layer ink. Here, after the adhesive layer ink is discharged onto the surface of the smooth layer 4 opposite to the thin film 3, the adhesive layer ink is exposed to light so as to be cured into a temporary curing state having a lower degree of curing than the main curing state. Then, the adhesive layer 5 is printed. In this case, the control device 104 applies the adhesive layer ink stored in the adhesive layer ink tank 106 by the ejection unit 109 to the surface of the smooth layer 4 opposite to the thin film 3, here, the third layer 43 of the smooth layer 4. The adhesive layer 5 can be controlled to be printed by being cured in a temporarily cured state by being exposed to the adhesive layer ink by the ultraviolet lamp 108 after being discharged onto the surface opposite to the second layer 42. is there. The control device 104 controls the ejection amount, ejection timing, ejection period, and the like of the adhesive layer ink ejected from the ejection unit 109 by the ejection control unit 104a, and the intensity and pinning of the ultraviolet rays that the exposure control unit 104b emits from each ultraviolet lamp 108 Controls exposure timing, pinning exposure period, and the like. Thus, the control device 104 prints the adhesive layer 5 so as to obtain a desired graphic to be transferred to the transfer target 50 according to the print pattern generated by the pattern conversion unit 104c. As a result, the transfer film 1 (see FIG. 1 and the like) is completed.

  As described above, the adhesive layer 5 may be a single layer, but may have a multilayer structure (for example, a three-layer structure) similarly to the smooth layer 4. However, in this case, as described above, the adhesive layer 5 does not need to have different degrees of ink curing when printed in each layer. In this case, for example, the control device 104 ejects the adhesive layer ink from the ejection unit 109 onto the smooth layer 4 in the forward path, the backward path, and the forward path of movement of the carriage 103 (see FIG. 3) along the main scanning direction. The adhesive layer ink may be cured into a temporarily cured state by pinning exposure by irradiating relatively weak ultraviolet light from the ultraviolet lamp 108 to print the adhesive layer 5 having a three-layer structure.

  Next, as a transfer step, as shown in FIG. 10, the transferred object 50 and the transfer film 1 are laminated so that the adhesive layer 5 is interposed between the transferred surface 51 of the transferred object 50 and the smooth layer 4. The thin film 3 is transferred to the transfer surface 51 by being pressed (step ST6). Here, for example, the worker manually presses the transfer film 1 from the base material 2 side to the transfer surface 51 side by using the pressing roller 300 or the like, and the thin film is formed by the adhesive force of the adhesive layer 5. 3 is transferred to the transfer surface 51.

  Next, as an irradiation step, as shown in FIG. 11, the adhesive layer 5, the second layer 42 of the smooth layer 4, and the third layer 43 are exposed to expose the adhesive layer 5 and the second of the smooth layer 4. The layer 42 and the third layer 43 are cured to the main curing state (step ST7). In this case, the control device 104 exposes the adhesive layer 5, the second layer 42 of the smooth layer 4, and the third layer 43 by the ultraviolet lamp 108 to expose the adhesive layer 5 and the second layer of the smooth layer 4. It is possible to execute the control for curing 42 and the third layer 43 to the state of the main curing. For example, as the carriage 103 (see FIG. 3) moves in the main scanning direction, the control device 104 smoothes the adhesive layer 5 by curing exposure by irradiating relatively strong ultraviolet rays from the ultraviolet lamp 108. The second layer 42 and the third layer 43 of the layer 4 are cured to the main curing state.

  Next, as a peeling process, as shown in FIG. 12, the base material 2 and the thin film 3 are peeled (step ST8). In this case, the worker peels and removes the base material 2 leaving the thin film 3 transferred to the transfer surface 51 of the transfer object 50. As a result, the transferred object 50 to which the thin film 3 having a desired figure corresponding to the shapes of the smooth layer 4 and the adhesive layer 5 is transferred is completed.

  As shown in FIG. 12, the transferred object 50 to which the thin film 3 has been transferred as described above includes an adhesive layer 5 provided in contact with the transferred surface 51 of the transferred object body 52, and the transferred object of the adhesive layer 5. The smooth layer 4 provided in contact with the surface opposite to the surface 51 and the thin film 3 provided in contact with the surface opposite to the adhesive layer 5 of the smooth layer 4 are provided. The hardness is higher. The transferred object 50 may further be top-coated so as to cover the surface of the thin film 3 and the transferred surface 51.

  Accordingly, the transferred object 50 manufactured by the above-described transferred object manufacturing method is a base layer having a relatively high hardness between the thin film 3 on which a desired figure is formed and the relatively soft adhesive layer 5. By interposing the smoothing layer 4 as the (leveling layer), the smoothness of the layer in contact with the thin film 3 can be improved. As a result, the transferred object 50 manufactured by the above-described transferred object manufacturing method can reduce unevenness on the surface of the thin film 3, and the gloss (glossy feeling) of the thin film 3 transferred to the transferred object 50. ) Can be improved.

  Further, the transferred object 50 manufactured by the above-described transferred object manufacturing method is smoothed by smoothing the unevenness formed on the surface of the first layer 41 opposite to the thin film 3 of the first layer 41. The smoothness of the layer 4 itself can be improved. Here, the transfer object 50 is formed as a multi-layer structure including the first layer 41 and the second layer 42 in which the smooth layer 4 has at least different degrees of ink curing as described above. The smoothness of the layer 4 itself can be improved. As a result, the transferred object 50 manufactured by the transferred object manufacturing method can further improve the glossiness of the thin film 3 transferred to the transferred object 50. Further, in this case, since the second layer 42 and the third layer 43 of the smooth layer 4 also function as the familiar layer with the adhesive layer 5, the conformability between the smooth layer 4 and the adhesive layer 5 is improved. can do.

  Further, in the above-described transfer object manufacturing method, the irradiation step ((Step ST7) is performed after the transfer step (Step ST6), and the adhesive layer 5, the second layer 42 of the smooth layer 4, and the third layer 43. As a result, in this transfer object manufacturing method, the thin film 3 can be transferred to the transfer surface 51 with the adhesive layer 5 being temporarily cured. Thus, even if the thin film 3 is pressed, the ink of the adhesive layer 5 or the like can be prevented from escaping to the outside, whereas in the above method for manufacturing a transfer material, the adhesive layer 5 or the like remains in a liquid state. In comparison, it is possible to improve workability when pressing the thin film 3 to make a flat surface, and in the above-described transfer object manufacturing method, the irradiation process (step ST7) is performed after the transfer process (step ST6). ) To perform the base material 2 in the peeling step (step ST8). When it is peeled off, the cut is improved, and the transferred thin film 3 edge can be clearly transferred, etc. Further, in the above-mentioned transfer object manufacturing method, the adhesive layer 5, the second layer 42 of the smooth layer 4, and By peeling off the base material 2 after performing the main curing of the third layer 43, the base material 2 can be easily peeled off. Since the base material 2 can be peeled off after bonding with sufficient strength, the base material 2 can be more appropriately peeled off from the transfer target 50.

  According to the transfer object manufacturing method according to the embodiment described above, the thin film 3 provided in contact with the sheet-like substrate 2 constituting the transfer film 1 is in contact with the surface opposite to the substrate 2. A smooth layer printing process (step ST2 to step ST4) for printing the smooth layer 4 on the surface, and an adhesive layer printing process (step ST5) for printing the adhesive layer 5 so as to contact the surface of the smooth layer 4 opposite to the thin film 3 side. And a transfer step of transferring the thin film 3 to the transfer surface 51 by laminating and pressing the transfer object 50 and the transfer film 1 so that the adhesive layer 5 is interposed between the transfer surface 51 and the smooth layer 4. (Step ST6) and a peeling step (Step ST8) for peeling the substrate 2 and the thin film 3 after at least the transfer step (Step ST6). The smooth layer 4 has higher hardness than the adhesive layer 5.

  According to the ink jet printer 100 according to the embodiment described above, the smooth layer ink tank 105 that stores the smooth layer ink that is the ink that forms the smooth layer 4 and has a degree of curing that changes when exposed. An adhesive layer ink tank 106 that stores an adhesive layer ink that is an ink that forms the adhesive layer 5 and has a degree of curing that changes when exposed; a smooth layer ink that is stored in the smooth layer ink tank 105; and A discharge unit 109 capable of discharging the adhesive layer ink stored in the adhesive layer ink tank 106, a smooth layer ink discharged from the discharge unit 109, and an ultraviolet lamp 108 capable of exposing the adhesive layer ink; A discharge unit 109 and a control device 104 for controlling the ultraviolet lamp 108, and the control device 104 is smoothed by the discharge unit 109. After the smooth layer ink stored in the ink tank 105 is discharged onto the surface of the thin film 3 provided in contact with the sheet-like substrate 2 constituting the transfer film 1 on the side opposite to the substrate 2, the ultraviolet lamp 108 is used. The smoothing layer ink is cured by exposing to the smoothing layer ink, and the adhesive layer ink stored in the adhesive layer ink tank 106 by the discharge unit 109 is the thin film 3 of the smoothing layer 4. Control of printing the adhesive layer 5 by being cured in a temporarily cured state by exposing to the adhesive layer ink by the ultraviolet lamp 108 after being discharged onto the opposite surface, and the thin film 3 on the transferred surface 51 After the transfer, the adhesive layer 5 is exposed to light by the ultraviolet lamp 108, and control to cure the adhesive layer 5 to the main curing state can be executed. , Smooth layer 4 has a higher hardness than the adhesive layer 5.

  According to the transfer film 1 according to the embodiment described above, the sheet-like substrate 2, the thin film 3 provided in contact with the substrate 2, and the surface of the thin film 3 opposite to the substrate 2 are in contact with each other. The smoothing layer 4 provided and the adhesive layer 5 provided in contact with the surface of the smoothing layer 4 opposite to the thin film 3 are provided. The smoothing layer 4 has higher hardness than the adhesive layer 5.

  According to the transferred object 50 according to the embodiment described above, the adhesive layer 5 provided in contact with the transferred surface 51 and the smooth surface provided in contact with the surface of the adhesive layer 5 opposite to the transferred surface 51. The layer 4 and the thin film 3 provided in contact with the surface of the smooth layer 4 opposite to the adhesive layer 5 are provided. The smooth layer 4 has higher hardness than the adhesive layer 5.

  Therefore, the transfer target 50 to which the thin film 3 is transferred from the transfer film 1 can reduce unevenness on the surface of the thin film 3 because the smooth layer 4 is interposed between the thin film 3 and the adhesive layer 5. The glossiness (glossiness) of the thin film 3 transferred to the transfer target 50 can be improved.

  The transferred object manufacturing method, the ink jet printer, the transfer film, and the transferred object according to the above-described embodiment of the present invention are not limited to the above-described embodiment, and various modifications can be made within the scope described in the claims. Is possible.

  The smooth layer 4 described above has been described as having a multilayer structure including at least the first layer 41 and the second layer 42. However, the present invention is not limited to this and may have a single-phase structure. Similarly, the adhesive layer 5 may have a single layer structure. Even in this case, the transferred object 50 to which the thin film 3 is transferred from the transfer film 1 can improve the glossiness of the thin film 3 transferred to the transferred object 50.

  In the above description, as the adhesive layer printing step (step ST5), the adhesive layer 5 is printed so as to be in contact with the surface opposite to the thin film 3 of the smooth layer 4. The adhesive layer 5 may be printed so as to be in contact with the transfer surface 51. That is, in the adhesive layer printing step (step ST5), the control device 104 discharges the adhesive layer ink stored in the adhesive layer ink tank 106 by the discharge unit 109 to the transfer surface 51 of the transfer body 50, and then the ultraviolet lamp. The control for printing the adhesive layer 5 may be executed by curing the adhesive layer ink in a temporarily cured state by exposing the adhesive layer ink to 108. That is, the adhesive layer 5 may be provided on the transfer film 1 side, or may be provided on the transfer surface 51 side of the transfer object 50. Even in this case, the transferred object 50 to which the thin film 3 is transferred from the transfer film 1 can improve the glossiness of the thin film 3 transferred to the transferred object 50. Further, in this case, the transferred object 50 can improve the alignment accuracy of the thin film 3 on the transferred surface 51.

  In the above description, the second layer 42 of the smooth layer 4 is an ink common to the smooth layer ink forming the first layer 41, here, UV (ultraviolet) curable ink (for example, “LH-100 Clear Liquid”). However, the present invention is not limited to this. The second layer 42 may be formed of, for example, solvent ink or water-based ink. However, as described above, when UV curable smooth layer ink is used as the second layer 42 of the smooth layer 4, the second layer 42 is formed using the same ink as that forming the first layer 41. In addition, the second layer 42 can be formed in a relatively short time. That is, the solvent ink and the water-based ink, for example, have a solid content of about 10%, whereas the UV curable smooth layer ink has a solid content of about 100%. For this reason, when the second layer 42 is formed of UV curable smooth layer ink, the working time for filling the solid content in the concave portion of the surface of the first layer 41 is compared with the case where solvent ink or water-based ink is used. Therefore, the use of the UV curable type smooth layer ink is overwhelmingly shorter. As a result, the manufacturing efficiency can be improved in the transfer object manufacturing method, the ink jet printer, the transfer film, and the transfer object described above.

  Further, both the irradiation step and the peeling step described above may be at least after the transfer step (step ST6), and the order of the irradiation step and the peeling step may be reversed.
