Description

Print method {PRINTING METHOD}

The present invention forms an ink coating surface by applying ink on a blanket, presses a steel plate on the ink coating surface to remove the ink in contact with the iron plate, and then transfers the ink remaining on the blanket to the printed object. The printing method (in this specification, this printing method is also called iron plate reverse printing method).

In the conventional general printing method, an ink layer is formed on a stroke by applying ink to a printing plate made of a flat plate, intaglio, iron plate or the like, and a printed image is formed by transferring the ink layer.

For this reason, the quality of a printed image depends on how to apply ink only to a stroke part and how to raise the transfer rate of ink with respect to a to-be-printed object.

On the other hand, in the recently developed iron plate inversion printing method (see Patent Document 1), as shown in FIG. 6, the ink coating device 23 is uniform on the blanket 22 attached to the surface of the body portion 21. The ink is applied to form an ink coating surface 1, and the ink coating surface 1 is pressed against the iron plate 24 to remove the ink 2 in the portion in contact with the iron plate 24 from the blanket 22. Thereafter, the ink 3 remaining on the blanket 22 is transferred to the printed object 4.

According to this iron plate reversal printing method, by using the blanket 22 having a high releasability like a silicone rubber, when the ink 2 of the non-deformation portion is transferred from the blanket 22 to the iron plate 24, further, the stroke portion When the ink 3 is transferred from the blanket 22 to the printed object 4, a transfer rate of 100% or the like is obtained, so that the image pattern accurately inverting the pattern of the convex portion 25 of the iron plate 24 A printed image having a film can be formed on the printed object 4.

Moreover, the inkjet system is known as a printing method which does not use a printing plate. Patent Literature 2 discloses a plateless transfer printing in which an image is formed on a transfer body containing a silicone rubber or a material having a constant releasability using an ink jet, and the ink on the transfer body is transferred to a printed object, thereby obtaining an image of interest. The law is disclosed.

Problems to be Solved by the Invention

However, when the area of the stroke portion is smaller than that of the non-stroke portion, according to the iron plate reversal printing method, it is necessary to remove most of the ink applied on the blanket with the iron plate, and the amount used for transferring and printing the printed object is small. Do. When a change in composition due to evaporation of an ink component, precipitation of a component, or aggregation occurs, reuse of the ink removed by the iron plate is difficult. Therefore, a large amount of ink must be used more drastically than transfer to the printed object. This leads to increased costs and increased environmental load due to disposal.

In the case of using the inkjet as described in Patent Document 2, since the inkjet image is formed by the aggregation of droplets, when the droplet diameter cannot be neglected compared with the dimension of the stroke portion, the edge of the image is formed on the outer peripheral shape of the droplet. It becomes wavy shape on the basis, and precise and sharp strokes are not obtained.

This invention is made | formed in view of the said situation, Comprising: It aims at providing the printing method which can reduce the waste of ink usage, can implement cost reduction, and can form a high-precision image.

(A)-(c) is explanatory drawing which illustrates each process which concerns on the example of the 1st aspect of the printing method of this invention, and FIG. 2 (a)-(c) is the printing method of this invention It is explanatory drawing which illustrates each process which concerns on the 2nd aspect example. In addition, each figure of this specification is the figure which showed typically for description of a printing process drawing, and the proportional relationship of a dimension did not reflect the actual situation in particular.

As shown in Fig. 1, the apparatus used in the first embodiment of the printing method of the present invention is the same as the apparatus used in the conventional iron plate reverse printing method, and the blanket 12 attached to the surface of the trunk portion 11 is shown. And an iron plate 14 having an ink application device 13 for applying ink on the blanket 12 and a convex portion 15 in a pattern in which the target image pattern formed on the printed material 4 is inverted. ) Is required. The iron plate 14 having a pattern in which the target image pattern is inverted has a concave portion 16 corresponding to a stroke portion on which the printed image is formed on the printed object 4, and a region other than the stroke portion (that is, non-scattering). The convex part 15 corresponding to the front part).

In the present invention, as the ink coating device 13, an apparatus by the inkjet method is used. In addition, as the blanket 12, it is preferable to use the material which has fixed mold release property, such as a silicone rubber.

The ink used in the present invention needs to be suitable for the iron plate reverse printing method and suitable for being discharged onto the blanket by ink jet and applied. There is no restriction | limiting in particular if it is equipped with the said aptitude, For example, the ink which added various components arbitrarily mainly with resin (polymer), a solvent, etc. are mentioned. For example, in the case of black ink or a coloring ink, color materials, such as dye and a pigment, are mixed, and in the case of electroconductive ink, conductive materials, such as metal powder, are mix | blended. In addition, various additives can be added to the ink used by this invention as needed. The green ink is exemplified by color index (CI) No. 36 as a pigment, melamine resin, fluorine-based surfactant, isopropyl acetate as a fast-drying solvent, diethylene glycol monoethyl ether acetate and propylene glycol as a slow-drying solvent. The ink containing the mixed solvent of monomethyl acetate, and other adjuvant is mentioned. Moreover, 1: 18-22 are preferable and, as for the mass ratio of a quick-drying solvent and a slow-drying solvent, about 1:20 are more preferable.

There is no restriction | limiting in particular also to a printed object, For example, plastics, paper, glass, a ceramic, a metal, etc. are mentioned.

(Ink coating process)

In order to implement the printing method of the present invention, first, as shown in Fig. 1A, ink is applied onto the blanket 12 to form an ink coating surface 1. In this invention, the ink application surface 1 on the blanket 12 is formed only in the area | region containing the part corresponding to the image pattern (stroke line) formed in the to-be-printed body 4, and its vicinity by the inkjet system. For example, when the linear pattern is to be formed, the ink coating surface 1 may be formed with a line width slightly thicker than the line width of the target pattern.

In the conventional iron plate reverse printing method, since the ink 2 in the portion corresponding to the non-deformation portion is removed by the iron plate even when applied on the blanket 12, it leads to waste of ink. Therefore, in the present invention, the portion 5 which does not apply ink in the region corresponding to the non-defective portion is formed so that the amount of the ink 2 removed by the iron plate 14 can be reduced. As a result, it is possible to reduce costs by reducing waste of ink.

(Image Forming Step)

Next, as shown in FIG. 1B, the iron plate 14 is pressed on the ink coating surface 1 to remove the ink 2 in the portion in contact with the iron plate 14 from the blanket 12. do. In this step, the ink 2 of the non-image portion is transferred to the iron plate 14 and removed. In the ink coating step, the ink coated surface 1 corresponds to a portion corresponding to the image pattern formed on the printed object 4 and Since it is formed only in the region including the vicinity, the ink transferred to the iron plate 14 only needs to be in the vicinity of the image pattern.

As a result, waste of ink usage can be reduced. Moreover, by removing the ink 2 of the non-image part from the ink application surface 1 on the blanket 12 by the iron plate 14, the edge (image part) of the ink 3 used as the image part which remains on the blanket 12 Since the shape of the boundary of the non-image portion can be aligned, even if the edge of the ink coating surface 1 formed by the ink jet becomes a wavy shape based on the outer circumferential shape of the droplets, the printing accuracy is not a problem. It is also possible to obtain sharp strokes.

(Transferring step)

Next, as shown in FIG. 1C, the ink 3 remaining on the blanket 12 is transferred to the printed object 4. In this step, as in the conventional iron plate reverse printing method, since the ink 3 remains only on the stroke portion on the blanket 12, it is possible to form an image having the desired stroke portion on the printed object 4.

Since the solvent 3 is partially dried prior to the transfer of the ink 3 remaining on the blanket 12, the pattern of the ink is hard to collapse during transfer, and the pattern reproducibility of the printing plate becomes good.

As an example of modification of the printing method of the present invention, an example in which the concave portion 17 is included in the non-deformation portion as the iron plate 14 is shown in FIG. 2. In other words, according to the present invention, since the convex portion 15 of the iron plate 14 does not need to be brought into contact with the portion 5 that does not apply ink on the blanket 12 in the image forming step, (b) of FIG. As shown in Fig. 1, on the iron plate 14, even if a portion corresponding to a part or all of the portion 5 on which the ink is not applied on the blanket 12 is used as the recessed portion 17, It does not interfere.

<Method of forming a plurality of different image patterns on one sheet of iron plate>

Moreover, in this invention, it is also possible to image-form several different image patterns (two or more) with one iron plate. For this purpose, one iron plate in which a plurality of different image patterns are formed as recesses is used.

First, any one image pattern is arbitrarily selected among a plurality of different image patterns formed as recesses in one iron plate, and in the ink coating step, the application place by the ink application device is controlled, and the selected image pattern is selected. An ink coated surface on the blanket is formed in a region including the portion corresponding to the vicinity and the vicinity thereof. In the image forming step, the selected image pattern can be imaged by pressing a single iron plate having a plurality of different image patterns formed as recesses to press the ink coating surface to remove the ink in a portion in contact with the iron plate from the blanket. Can be. Then, the image pattern arbitrarily selected can be printed by transferring the ink remaining on the blanket to the printed object.

In order to use a plurality of different image patterns (not necessarily all of the image patterns that can be formed with the iron plate) formed on one steel plate as recesses, each image pattern is selected in an arbitrary order, and the selected image is selected. For each pattern, printing is performed by an ink coating, image forming, and transfer process. In these series of printings, a plurality of different blankets may be used as the blanket, or the same blanket may be used multiple times. Thereby, it becomes possible to image-form several different image patterns with one iron plate. As a result, it is possible to reduce the cost of manufacturing the iron plate, reduce the process of cleaning the iron plate every time printing, reduce the size of the entire printing apparatus, and reduce the installation space of the printing apparatus.

For example, FIG. 3 shows the case where a plurality of different image patterns are parallel thin line patterns having different pitches. In FIGS. 3B and 3E, the iron plate 14 having the concave portion 16 formed at the pitch a includes the parallel thin wire pattern of the pitch a, the parallel thin wire pattern of the pitch 2a, and the pitch 3a. It can be considered that a plurality of patterns are included, such as a parallel thin line pattern and a parallel thin line pattern having a pitch of 4a. That is, this iron plate 14 has a pitch of a, 2a, 3a, 4a,... It is possible to image-form a parallel thin line pattern having a plurality of pitches.

As a specific example, the method of printing the parallel thin line pattern of the pitch a and the parallel thin line pattern of the pitch 2a using the iron plate 14 in which the recessed part 16 was formed in pitch a is demonstrated, referring FIG. .

In order to print the parallel thin line pattern of pitch a, in the ink application process, as shown to Fig.3 (a), the ink application surface 1 is made to the area | region containing the line width part of a parallel thin line pattern, and its vicinity. It forms with the pitch a. In the image forming step, as shown in Fig. 3B, the line width of the line is brought into contact with the convex portion 15 of the iron plate 14 by contacting the ink application surface 1 coated on the blanket 12 with a pitch a. The non-repudiation excess ink 2 is removed from the blanket 12. Thereby, the parallel thin line pattern of pitch a is image-formed on the blanket 12. As shown in FIG. In the transfer step, as shown in FIG. 3C, the ink 3 remaining on the blanket 12 is transferred to the printed object 4. Thereby, the parallel thin line pattern of pitch a is printed on the to-be-printed body 4.

In addition, in order to print the parallel thin line pattern of pitch 2a, as shown in FIG.3 (d), an ink application surface 1 in the area | region containing the line width part of a parallel thin line pattern and its vicinity is shown. ) Is formed at the pitch 2a. In the image forming step, as shown in FIG. 3E, the line width of the line is brought about by contacting the convex portion 15 of the iron plate 14 with the ink coating surface 1 coated on the blanket 12 at a pitch 2a. The non-repudiation excess ink 2 is removed from the blanket 12. Thereby, the parallel thin line pattern of pitch 2a is image-formed on the blanket 12. As shown in FIG. In the transfer step, as shown in FIG. 3F, the ink 3 remaining on the blanket 12 is transferred to the printed object 4A. As a result, a parallel thin line pattern having a pitch of 2a is printed on the printed object 4A.

Similarly, pitches 3a, 4a,... The printing of the parallel thin line pattern can also be easily performed by controlling the ink coating pitch by the inkjet method. On the other hand, in FIG. 3, although the printed object 4 to which the parallel thin-line pattern of pitch a is printed, and the printed body 4A to which the parallel thin-line pattern of pitch 2a are printed, were distinguished by changing the code | symbol on account of description, this invention is The present invention is not limited to the case where a plurality of different image patterns are printed on a plurality of different printed objects, but can be applied to the case where a plurality of different image patterns are printed on a single printed object.

In the method of image forming a plurality of different image patterns with one iron plate, the plurality of image patterns can be present at any place on the iron plate. For example, as in the example shown in FIG. 3, when forming parallel thin wire patterns of several different pitches, the iron plate which formed the recessed part by the pitch which becomes the largest common factor of the pitch of a parallel fine wire pattern (ie, a parallel thin wire pattern) When the concave is formed with the number of units per unit length to be the least common multiple of the unit length), the pitch of the parallel thin wire pattern is a multiple of the pitch of the concave portion of the iron plate, thereby forming an image with one sheet of iron. This becomes possible.

As another example, there is a rectangular pattern and a triangular pattern in one iron plate, sometimes using only rectangular parts, sometimes using only triangle parts, and sometimes using both rectangular parts and triangle parts simultaneously. It can also be used.

In addition, in the case of forming an image of a plurality of different image patterns with one iron plate, it is also possible to apply a method of printing a plurality of image patterns on one printed object described below. For example, there is a rectangular pattern and a triangular pattern in one iron plate, and when printing using both a rectangular part and a triangle part simultaneously, red ink is used for the rectangular pattern and blue ink is used for the triangle pattern. It can be made into two colors. As another example, when forming a parallel thin line pattern, the application of changing the color of each thin line into a desired combination, for example, forming a pattern in which the red thin line and the blue thin line alternately repeat is possible.

<Method for printing a plurality of image patterns on one printed object>

In addition, in this invention, since the ink application surface on the blanket is formed in the area | region containing the part corresponding to the image pattern formed in a to-be-printed object, and its vicinity by the inkjet system, it is a some ink on one blanket. It is possible to form an application surface and to transfer these plural ink application surfaces to the printed object at one time from the one blanket. Therefore, in order to print plural (two or more) image patterns on one printed object with each ink, one blanket with a plurality of ink heads can be used. In this case, the method of attaching a plurality of ink heads to one blanket includes a method by mounting one ink coating device having a plurality of ink heads, and an ink coating device having one or two or more ink heads. A method of arranging two or more (the number of ink heads included in each ink coating apparatus may be the same or different numbers) and arranging the required ink heads may be mentioned.

By using different kinds of inks as respective inks applied from the respective ink heads, printing by a plurality of kinds of inks can be realized in one transfer.

For example, FIG. 4 shows a pattern of three colors of red (R), green (G), and blue (B) of a color filter on a printed body on which a black matrix BM (lattice black line pattern) is formed on a printed surface. An example of the method of forming a figure is shown. According to this method, three colors of filter patterns can be formed at once, and the process can be shortened and productivity can be improved.

In the ink coating step, as shown in Fig. 4A, an ink head 13R for applying red ink, an ink head 13G for applying green ink, and an ink head for applying blue ink ( Using the blanket 12 to which the 13B is attached, each ink application surface from the respective ink heads 13R, 13G, and 13B to a region including a portion corresponding to each image pattern and its vicinity (1R), (1G), and (1B) are formed at different positions of one blanket 12.

In the image forming step, as shown in Fig. 4B, the concave portion 16R corresponding to the red image pattern, the concave portion 16G corresponding to the green image pattern, and the blue image pattern are shown. The iron plate 14 having the corresponding concave portion 16B and the convex portions 15 formed between these concave portions 16R, 16G, and 16B was applied onto the blanket 12. The three ink coating surfaces 1R, 1G, and 1B are brought into contact with the convex portion 15 of the iron plate 14, thereby making excess ink 2R, 2G, and 2B between the respective image patterns. Remove from blanket (12). As a result, image patterns 3R, 3G, and 3B of three colors are image-formed on one blanket 12.

In the transfer step, as shown in FIG. 4C, the inks 3R, 3G, and 3B remaining on the blanket 12 are transferred to the printed object 4. Thereby, three color image patterns are printed on the printed object 4. In the example of FIG. 4C, the black matrix BM is formed in advance at the boundary of the three-color image pattern, and the three-color inks 3R, 3G, and 3B on the blanket 12 are black matrices. It is transferred onto the printed material 4 including a part on the BM. As a method of forming a black matrix BM in the to-be-printed body 4, the iron plate reverse printing method of this invention and the conventional iron plate reverse printing method are illustrated.

As mentioned above, referring to FIG. 4, in order to apply each said ink as a method of printing several image patterns 3R, 3G, and 3B on each printed object 4 with each ink. Using one blanket 12 equipped with a plurality of ink heads 13R, 13G, and 13B, corresponding to each image pattern from each ink head 13R, 13G, 13B After the respective ink coating surfaces 1R, 1G, and 1B are formed at different positions of one blanket 12 in the region including the portion to be covered and the vicinity thereof, a plurality of image patterns are formed in the concave portion 16R. ), (16G), the ink of the part which contacts the said iron plate 14 by pressing the one iron plate 14 formed as (16B) to each ink application surface 1R, 1G, and 1B By removing (2R), (2G), and (2B) from the blanket 12, a plurality of image patterns 3R, 3G, and 3B are placed on one blanket 12 on one sheet iron plate ( 14) a method of forming an image at once Explained.

In FIG. 4, the case where the application | coating pattern of the ink of three colors R, G, B to the blanket 12 is a parallel line pattern of the longitudinal direction of the cylindrical trunk | drum 11 is taken as an example. This is one example, and as another example, the pattern applied in the circumferential direction of the trunk portion 11 (see FIG. 5 (a)) or the rectangular ink coating portion in the longitudinal direction and the circumference of the trunk portion 11. Even when using the mosaic-shaped application pattern (refer FIG. 5 (b)) two-dimensionally arranged in the direction, using the iron plate corresponding to each application pattern, the color filter by the method shown to (a)-(c) of FIG. Can be formed on the printed object.

In addition, the iron plate used for image formation of several image pattern 3R, 3G, and 3B is not limited to one sheet, It is also possible to use two or more iron plates together. For example, a plurality of iron plates having recesses corresponding to the respective image patterns 3R, 3G, and 3B are used, and each of the ink coating surfaces 1R, 1G, and 1B is respectively By pressing the iron plate and removing the ink of the portion in contact with the iron plate from the blanket, a plurality of image patterns 3R, 3G, and 3B can be formed on one blanket 12.

For example, as a group of the iron plate which image-forms three color image patterns 3R, 3G, and 3B, the group shown below can be illustrated. Even if the number of types of image patterns are different, it will be possible to prepare and use an appropriate number of iron plates according to this example.

(1) The red iron plate which formed the red image pattern 3R as the recessed part 16R, the green iron plate which formed the green image pattern 3G as the recessed part 16G, and the blue image pattern ( (2) The red image pattern 3R and the green image pattern 3G are formed as the recessed portions 16R and 16G, and the tank which consists of three sheets of the blue iron plate in which 3B was formed as the recessed part 16B. A pair consisting of one red / green iron plate and two blue iron plates in which the blue image pattern 3B is formed as the recessed portion 16B, (3) the red image pattern 3R and the blue image pattern 3B. ), A pair consisting of two sheets of a red / blue iron plate formed as recesses 16R and 16B, and a green iron plate formed by forming green recesses 3G as recesses 16G, (4) red Red iron plate in which the image pattern 3R is formed as the concave portion 16R, and the green image in which the green image pattern 3G and the blue image pattern 3B are formed as the concave portions 16G and 16B. Blue dragon Article made of two sheets of plate.

In each iron plate, a convex portion for removing excess ink includes a position in the vicinity of an image pattern imaged with the iron plate, and is formed at a position that does not include all image patterns imaged on one blanket. There is a need.

For example, in the case of the red iron plate (green and blue do not form an image) in which the red image pattern 3R is formed as the concave portion 16R, the convex portion 15 is a red image. Including the position near the pattern 3R, the red ink 2R can be contacted and removed while leaving the red image pattern 3R on the blanket 12, and the green and blue It is necessary not to contact the ink used as the image patterns 3B and 3G. However, the convex part 15 of the said red iron plate contains the positions of the vicinity of green and blue image patterns 3G and 3B, and it is ink 2G and green which should be removed contacting green and blue ( There is no problem in contact with 2B).

As described above, according to the printing method of the present invention, the amount of ink to be removed from the blanket 12 with the iron plate 14 can be reduced, and the waste of the ink used can be reduced and the cost can be realized. In addition, since the shape of the edge (the border between the image portion and the non-image portion) of the ink on the blanket 12 can be arranged by the iron plate 14, high-definition image can be formed.

Further, by forming a plurality of different image patterns with one iron plate, reduction of the number of plates, production of various image patterns with one blanket and a unit of plate, compactness of the entire printing apparatus, and installation of a printing apparatus The space can be reduced.

Further, by applying a plurality of types of ink to one blanket at a time, the number of plates and blankets is reduced, and multicolor printing is performed at one time by one blanket and plate unit. The installation space can be reduced.
