Description

  The present invention relates to a manufacturing method and a printing apparatus for a printed material on which metal powder or metal foil is attached.

  For example, in reprints such as paintings and hanging scrolls, posters, storefronts, banners in stores, etc., picture areas where pictures and letters are expressed with coloring materials such as ink, and metal expressed with metal powder and metal foil Some include glossy areas.

Reprinted prints, which are examples of printed materials including these metallic gloss regions, have conventionally been produced by, for example, forming a pattern printing layer on a paper base material by ink jet printing, and pasting the paper base material on which the pattern printing layer is formed on a mount. An adhesive layer is formed on the material by offset printing, a metal foil is attached to the adhesive layer, this is cured, and a pattern printing layer on the gold foil is formed by offset printing.

  Generally, printing methods such as lithographic printing, letterpress printing, intaglio printing, and ink jet printing have specific printing errors. Normally, even in printing using a single printing method, registration is performed carefully in multicolor printing in which plates such as CMYK are stacked.

  In general, when two or more printing methods are used in combination with a single printed matter, it is extremely difficult to register the plates.

  Furthermore, when paper is used as the drawing (printing) substrate, the paper substrate expands and contracts due to moisture. Water that causes expansion and contraction of the paper base material in the printing process includes not only moisture contained in the paper base material and humidity in the air, but also water used for offset printing and water contained in the ink. Similarly, even if the drawing base material is a plate, the base material may warp due to an increase or decrease in moisture or other reasons.

  Furthermore, reprinted prints, posters, banners, and the like are, for example, many large-sized prints with a side of more than 1 m, and there are mixed patterns and metallic gloss areas, making it difficult to register multiple versions. That is, when printing a plurality of plates, it is difficult to maintain the pattern position accuracy.

  Since the conventional printed matter uses both the inkjet printing method and the offset printing method, it is difficult to register the pattern and the adhesive layer. Moreover, when using a paper base material, the paper base material expands and contracts due to water or the like contained in the ink in the step of forming a pattern by ink jet printing. And an offset printing process is performed through the process affixed on a mount. For this reason, the positional error of the pattern and adhesive layer resulting from expansion and contraction of the paper base material is unavoidable.

  In addition, reprints and banners are generally produced in small quantities, and if offset printing is used, the time and expense of creating plates cannot be absorbed into the costs required for small quantities of products, resulting in expensive prints. .

Therefore, an object of the present invention is to obtain a printed material manufacturing method and a printing apparatus with improved drawing position accuracy of a pattern and a metallic gloss region in a printed material including a metallic gloss region.
Moreover, this invention makes it a subject to obtain the manufacturing method and printing apparatus of a printed matter suitable for a small amount production in the printed matter containing a metallic luster area.

  The method for producing a printed material according to the present invention is to print with overlapping plates. However, since the drawing of the pattern and the formation of the adhesive layer are performed in the same printing format, there is only one kind of error peculiar to the printing method. Furthermore, since the coordinate error of the pattern is measured and the adhesive pattern correction data is obtained to form the adhesive layer, the error caused by overlapping the plates is further minimized. Therefore, it is a manufacturing method capable of obtaining a printed matter in which the positional accuracy of the pattern and the metallic gloss region is improved.

For this reason, printing can be performed without causing stretching or warping of the drawing base material due to increase or decrease of moisture, and the position accuracy of the pattern and the adhesive layer (and thus the metallic gloss region) is further improved. A printing apparatus capable of printing a printed matter. This printing apparatus is particularly preferable as a printing apparatus for paper substrates.

  Hereinafter, a printed matter manufacturing method and a printing apparatus according to an embodiment of the present invention will be further described with reference to the drawings. The dimensions, materials, shapes, relative positions, etc. of the members and parts described in the embodiments of the present invention are not intended to limit the scope of the present invention only to those unless otherwise specified. It is just an illustrative example.

  In the present invention, the micro droplet ejection method is a method for ejecting micro ink droplets onto a sheet-like medium at high speed and printing a predetermined pattern. A typical printing method is so-called ink jet printing.

  FIG. 1 is a plan explanatory view of a finished printed matter 7 printed by the manufacturing method of the present invention, and FIG. 2 is a cross-sectional explanatory view taken along line 1A-A 'in FIG. FIG. 1 and FIG. 2 are explanatory diagrams for explaining the invention. For the purpose of facilitating understanding, the vertical and horizontal scales and the length ratios of the constituent parts are different from the actual ones. The same applies to the following explanatory diagrams (FIGS. 3, 4, 6, 7, 8, 9, 10).

  The finished printed matter 7 has metallic gloss regions 11 and 12 and pictures 14, 16 and 17 drawn on the surface of the drawing substrate 5. The metallic gloss regions 11 and 12 are formed by forming the adhesive layer 13, attaching the metal powder 20 to the surface before the adhesive layer 13 is solidified, and fixing the metal powder 20 by the solidification of the adhesive layer 13. . The adhesive layer 13 is formed by ink jet printing. The patterns 14, 16, and 17 are printed by inkjet printing.

  The metallic gloss region 11 is obtained by drawing a pattern 17 on the surface of the drawing base 5, forming an adhesive layer 13 on the surface of the pattern 17, and further attaching metal powder 20. The metallic gloss region 12 is obtained by forming the adhesive layer 13 directly on the surface of the drawing base material and further attaching the metal powder 20. The metallic gloss region in the present invention includes both the metallic gloss region 11 shown and the metallic gloss region 12 shown.

  The drawing substrate 5 is not particularly limited as long as it can be printed by inkjet printing. Examples of the drawing substrate 5 include paper, cloth, plate, and plastic film. The paper includes Japanese paper, western paper, and synthetic paper. The cloth is, for example, silk cloth, linen cloth, cotton cloth, synthetic fiber cloth, and non-woven cloth is also included. The board includes a natural board, a plywood board, a board board, and a plastic board. These drawing substrates are preferably coated with a surface finishing agent having ink jet ink suitability. The surface finishing agent is not particularly limited, and examples thereof include a silica binder mainly composed of an ethylene-vinyl acetate copolymer and an ink fixing agent mainly composed of a specially modified polyamine.

  The metal powder may be a metal foil. The material of the metal powder or metal foil is gold, silver, brass or the like.

  On the surface side of the metallic gloss region, an overlying pattern layer may be further printed by ink jet printing. FIG. 3 and FIG. 4 are cross-sectional explanatory views of a finished printed matter in which a repeated picture layer is applied to the metallic gloss region.

  Referring to FIG. 3, pattern 17 is printed on the surface side of drawing substrate 5, metal powder 20 is applied to adhesive layer 13 formed in a superimposed manner, and coating pattern 18 is formed thereon. ing.

  In addition, referring to FIG. 4, overprinted pattern 19 a is printed only on a part of the metallic luster region to which metal powder 20 is applied, and at the same time, overpainted pattern 19 b is printed on the surface of drawing substrate 5. ing.

  FIG. 5 is a process explanatory diagram of the method for producing a printed material according to the present invention. FIG. 6 is an explanatory diagram for explaining an example of a pattern coordinate measurement process, a pattern error calculation process, and an adhesive pattern correction data calculation process. FIG. 7 shows a pattern coordinate measurement process, a pattern error calculation process, and an adhesive pattern correction data calculation process. FIG. 8 is an explanatory diagram for explaining another example of the pattern coordinate measurement process, the pattern error calculation process, and the adhesive pattern correction data calculation process.

  First, pattern basic data and adhesive pattern basic data, which are process i, are created. That is, an image including a metallic luster area and a pattern area expressed by metal powder or metal foil to be created by printing is prepared. In the present invention, an image includes a concrete painting, an abstract painting, a photograph, a character, an abstract figure, or a mixture of two or more of these. In addition, the images include historical cultural assets, modern paintings, original pictures such as posters and banners. Further, it may be an image drawn on Japanese paper (for example, a picture or a hanging shaft), or a picture drawn directly on a wooden board (a door picture, a wall picture, etc.).

  The image is scanned with a scanner to create RGB image data or CMYK image data. Next, the created data is edited and divided into metallic gloss data and other color data. Here, the metal gloss data is referred to as adhesive pattern basic data because it is region data representing metal gloss in which an adhesive layer is formed by printing and metal powder or metal foil is attached to the adhesive layer. The other color data is called pattern basic data because it becomes area data for forming a pattern by printing.

  The basic pattern data may include print data for register mark printing.

  In addition, in some cases, the painted pattern basic data, which is color data to be painted on the metallic gloss data (and the proximity area), is created.

  Next, process b is performed and the drawing base material is fixed to the bed. When a substrate such as paper that easily transmits moisture is used as the drawing substrate, the contact surface of the bed with the drawing substrate is preferably made of a material that does not shrink due to moisture. For example, stainless steel and synthetic resin.

  The drawing substrate is fixed to the bed with its back surface in contact with the bed. Examples of the fixing method include a fixing method using reduced pressure adopted in a bed, which will be described later with reference to FIG. 10, a fixing method using an adhesive such as cloth laver or glue, or a fixing method using a pressing plate.

  There is at least one position where the back surface of the drawing substrate and the bed are fixed at the peripheral portion of the drawing substrate, and from the center of the drawing substrate, usually within a circle with a radius of 50 mm, more preferably a circle with a radius of 25 mm. It is preferable that it exists in at least one place in the inside. This is to avoid stretching and warping of the drawing substrate. From the viewpoint of fixing the drawing substrate from the back side, a fixing method using reduced pressure or a fixing method using an adhesive is preferable as a fixing means for a printed region such as a central portion of the drawing substrate. In addition to the fixing method using reduced pressure or the fixing method using an adhesive, a fixing method using a pressing plate can be adopted for fixing the blank portion of the drawing base material, which may be present on the surface. .

  It is preferable that the interval between the plurality of fixed positions is usually within 100 mm, more preferably within 50 mm. Such an arrangement of a plurality of fixed positions is preferable when a large-sized drawing base material (particularly a paper base material) is used. Furthermore, it is preferable that the plurality of fixing positions of the drawing base material and the bed are evenly distributed over the entire surface of the drawing base material. In the case of a fixing method using decompression described later, the fixing position means an opening of a decompression tube on the bed surface. When using an adhesive, it is more preferable to stick the entire surface of the drawing base material to the bed.

  Process a and process b are not related, and either can be performed first or can be performed simultaneously.

  Subsequently, pattern printing, which is the process C, is performed. The pattern printing uses a micro droplet discharge method, and prints the pattern on the surface of the drawing substrate fixed to the bed according to the basic pattern data. Since the basic pattern data includes C, M, Y, and K data as required and one or more special color data as necessary, the ink liquids for each color of C, M, Y, and K can be used as necessary. If necessary, one or a plurality of special color ink liquids are ejected, and a pattern is printed on the surface of the drawing substrate.

  Subsequent to the pattern printing process (process c), pattern coordinate measurement as process D is performed. The pattern coordinate measurement step is a step of measuring the pattern printed in the step C to obtain pattern coordinate measurement data. The pattern coordinate measurement is performed, for example, by scanning an optical sensor that measures a minute point independently along the vertical axis and the horizontal axis and scanning the entire surface of the drawing substrate. The pattern measurement data can be obtained by integrating the drive information for scanning and the color information detected by the optical sensor. Also, the pattern coordinate measurement can be performed, for example, by taking a picture of the pattern and obtaining digital data.

  Next, the pattern position error calculation which is the process e is performed. The design position error calculation is a step of calculating the design position error by comparing and calculating the design basic data and the design coordinate measurement data.

  FIG. 6 shows a printed picture 121 shown by a solid line and a graphic 21 based on the picture basic data shown by a broken line. In addition, printed registration marks 123, 124, 125, and 126 are illustrated, and registration marks 23, 24, 25, and 26 based on the basic pattern data are illustrated.

  The coordinates of the printed registration marks 123, 124, 125, 126 are measured using, for example, an optical sensor to obtain pattern coordinate measurement data (step D). Next, the pattern position error calculation which is the process e is performed. The pattern position error calculation step and the subsequent adhesive pattern correction data calculation step are performed using, for example, a computer. In the example shown in FIG. 6, the position error is a distance P in the downward direction and a distance Q in the left direction.

  Subsequently, adhesive pattern correction data, which is a process, is calculated. FIG. 6 illustrates a graphic 22 based on the adhesive pattern basic data and a graphic 122 based on the adhesive pattern correction data. Applying the distance P in the downward direction and the distance Q in the left direction, which is the position error obtained in the pattern position error calculating process, to the basic data for the adhesive pattern, the adhesive pattern correction data moved downward and to the left is obtained. .

  Note that FIG. 6 has been described on the assumption that an adhesive layer is formed on the entire surface of the graphic 21 on the pattern basic data. In other examples described with reference to FIGS. 7 and 8, it is assumed that an adhesive layer is formed on the entire surface of the graphic 21 on the basic pattern data.

  Based on FIG. 7, another example of process e and process will be described. In FIG. 7, the same reference numerals as those in FIG. 6 are assigned to the printed pattern, the figure based on the pattern basic data, the figure based on the bonded pattern basic data, the figure based on the bonded pattern correction data, and the like. The same applies to FIG.

  In the example of FIG. 7, the coordinate error between the graphic 21 of the basic pattern data and the printed pattern 121 is an angle α on the left. Therefore, the angle α is applied to the adhesive pattern basic data to the left to obtain the adhesive pattern correction data (figure 122).

  In the example of FIG. 8, the coordinate error between the pattern 21 of the pattern basic data and the printed pattern 121 extends downward by a coefficient t proportional to the distance. Therefore, the adhesive pattern correction data (figure 122) is obtained by applying a coefficient t proportional to the distance downward to the basic pattern data.

  In FIG. 8, the vertical side and the upper horizontal side of the pattern 21 of the pattern basic data and the printed pattern 121 match, and the registration marks 23 and 123 and the registration marks 24 and 124 match. For ease of understanding, the positions are shown shifted.

  The pattern coordinate measurement, the pattern position error calculation, and the adhesive pattern correction data calculation may be performed for every region on the drawing base material, or may be performed for each region by dividing the entire region into a plurality of regions. Also, the pattern coordinate measurement is not limited to the method of using the register mark, and for example, a specific portion in the pattern may be determined and used as a specific point for measurement.

  Subsequently, a process of forming an adhesive layer on the drawing base material fixed to the bed in accordance with the adhesive pattern correction data is performed using the micro droplet discharge method which is the process step. As the adhesive for forming the adhesive layer, an ultraviolet curable resin, glue or the like can be used. Specific examples of the ultraviolet curable resin include an ultraviolet curable epoxy acrylate resin.

  Next, metal powder adhesion which is process e is performed. Before the adhesive layer formed in the above step is solidified, for example, it is performed by shaking off the metal powder using a paint brush or the like. Moreover, it may replace with metal powder and may affix metal foil. The metal powder adhesion step may be performed while the drawing base is fixed to the bed, or may be performed after the drawing base is removed from the bed.

  Then, the adhesive layer is solidified. That is, when an ultraviolet curable resin is used, the metal powder is fixed at the same time as the adhesive layer is solidified by irradiating ultraviolet rays. If glue is used, dry it naturally.

  Finally, the work which removes a drawing base material from a bed is performed as needed.

  In the printed matter manufacturing method described above, the adhesive layer may be formed twice (or three times or more). That is, an adhesive layer is formed over the entire area of the metallic gloss region at the first time, and then the microdroplet discharge device is returned to the printing start origin to form a second adhesive layer. The adhesive layer for the second time may be formed again over the entire area of the adhesive layer formed for the first time (thick coating), and partially overlaps the adhesive layer formed for the first time. An adhesive layer may be formed (partial coating). When thick coating is performed, the adhesive strength of metal powder or metal foil is improved. By applying partial thick coating, gradation can be expressed.

  The manufacturing method according to the present invention is a method in which the positional accuracy of the pattern and the adhesive pattern is improved. Similarly, the positional accuracy of the adhesive layer formed a plurality of times is improved. For this reason, it is a preferable manufacturing method for forming the adhesive layer a plurality of times.

  Moreover, in the manufacturing method concerning this invention, formation of an adhesive bond layer may be divided and performed. The deposition of metal powder or metal foil is a time consuming process and must be completed before the adhesive is solidified. Therefore, for example, the entire drawing surface is divided into two, an adhesive layer is formed in one divided surface, and metal powder or metal foil is attached. Then, an adhesive layer is formed in the remaining divided surface, and metal powder or metal foil is attached. The method for producing a printed material according to the present invention is suitable for performing the above-mentioned divided formation of the adhesive layer because the adhesive layer is formed by a method of discharging fine droplets. Thereby, it becomes possible to distribute the working time of the printing worker more freely.

  Furthermore, in the manufacturing method according to the present invention, a coating pattern may be printed after the metal powder adhesion step (step H). The overlying pattern is preferably performed using a fine droplet discharge method. Moreover, it is preferable to perform a metal powder adhesion process (process H), without performing the refixing operation | work to the bed of a drawing base material by performing with the drawing base material being fixed to the bed. Furthermore, using the pattern position error obtained by the process e, it is possible to correct the overlaid pattern basic data to obtain overlaid pattern correction data, and to print the overlaid pattern according to the overlaid pattern correction data. Further preferred. The pattern position error may be a position error obtained by newly measuring the pattern coordinates or the metallic gloss coordinates and calculating one of the position errors before printing the overlaid pattern.

  Next, the printing apparatus according to the present invention will be described. FIG. 9 is an explanatory plan view of the printing apparatus 1, and FIG. 10 is an explanatory sectional view of the bed 81.

  The printing apparatus 1 can be roughly divided into a printing unit 2 and a control unit 3. The printing unit 2 includes a bed 81 for fixing the drawing base material 5.

When the Y-axis end position is repeated, one Y-axis scan is completed. Thereafter, the slider 341 and the slider 342 are moved by the operation of the linear motor, whereby the pattern Y guide shaft 33 is moved by a minute distance, and the next Y-axis scanning is similarly performed. By repeating this operation, the entire surface of the drawing substrate 5 is scanned, and pattern drawing is performed.

  There are also a slider 441 with a linear motor placed on the magnet plate 31 and a slider 442 placed on the second X guide shaft 32. An adhesive handle Y guide shaft 43 is stretched over the slider 441 and the slider 442. The adhesive handle Y guide shaft 43 moves in the left-right direction (X-axis direction) in the drawing by the movement of the slider 341 by the operation of the linear motor. The slider 442 slides on the second guide shaft 32. The second guide shaft 32 may be replaced with a magnet plate of a linear motor, and the slider 442 may be replaced with a slider with a linear motor.

  Referring to FIG. 10, a large number of openings 82 are formed on the surface of the bed 81, and the openings 82 are circular with a diameter of several millimeters. The opening 82 communicates with the decompression pipe 83. When the back surface 62 of the drawing base 5 is brought into contact with the surface of the bed 81 and the decompression tube 83 is decompressed by a vacuum pump (not shown), the drawing base is fixed to the surface of the bed 81.

  Although the size of the bed is not particularly limited, for example, the X-axis direction is 6500 mm and the Y-axis method is 2650 mm.

  The control unit 1 is a computer, and includes a pattern basic data recording unit 51, an adhesive pattern basic data recording unit 52, a pattern position error calculation unit 53, an adhesive pattern correction calculation unit 54, and a drive discharge control unit 58.

  Next, operations and operations of the printing apparatus 1 will be described.

  First, in the same manner as described in the method for producing a printed material, basic pattern data and basic pattern data are prepared. Then, the basic pattern data is recorded in the basic pattern data recording unit 51 and the basic bond data is recorded in the basic bond data recording unit 52.

  The drawing base material 5 is prepared, and the back surface of the drawing base material 5 is brought into contact with the surface of the bed 81. The vacuum pump is operated so that the decompression tube 83 is in a decompressed state, and the drawing substrate 5 is fixed to the bed 81. Thereafter, the operation of the vacuum pump is continued at least until the adhesive layer is formed, and the state in which the drawing base material 5 is fixed to the bed is maintained and continued.

  Next, the drive discharge controller 58 sends a signal to the linear motor (341) and the design Y-axis drive means 35 in accordance with the design basic data recorded in the design basic data recording unit 51, and simultaneously sends a signal to the design recording head 36. The pattern recording head 36 is scanned and fine droplets of the colored liquid are ejected to record the pattern on the surface 61 of the drawing substrate 5.

  Next, the drive discharge controller 58 sends a signal to the linear motor (441) and the adhesive handle Y-axis drive means 45 to scan the optical sensor 47. The detection signal of the optical sensor 47 and the scanning signal transmitted from the drive / ejection control unit 58 are combined to generate pattern coordinate measurement data, which is recorded in the pattern coordinate measurement data recording unit 55.

  Subsequently, the pattern position error calculation unit 53 compares the pattern basic data recorded in the pattern basic data recording unit 51 with the pattern coordinate measurement data recorded in the pattern coordinate measurement data recording unit 55, and calculates an error value. calculate. The error value is recorded in the error value recording unit 56. For example, the error value may be a number that is added to or subtracted from the distance from one or more specific points, may be a rotation angle from a specific direction, and may be a coefficient that is multiplied by the distance from the specific point.

  Next, the bonded pattern correction calculation unit 54 calculates the bonded pattern correction data by applying the error value recorded in the error value recording unit 56 to the bonded pattern basic data recorded in the bonded pattern basic data recording unit 52. This is recorded in the adhesive pattern correction data recording unit 57.

  Thereafter, the drive discharge controller 58 sends a signal to the linear motor (441) and the adhesive pattern Y-axis driving means 45 according to the adhesive pattern correction data recorded in the adhesive pattern correction data recording unit 57, and at the same time, the adhesive pattern recording head. A signal is sent to 46, and the adhesive pattern recording head 46 is scanned, and a fine droplet of the adhesive liquid is ejected to record the adhesive layer on the surface 61 of the drawing substrate 5.

  Thereafter, the drawing substrate 5 is removed from the bed 81, or metal powder or metal foil is adhered to the adhesive layer while maintaining the state where the drawing substrate 5 is fixed to the bed 81. And after solidifying an adhesive bond layer, the drawing base material 5 is removed from the bed 81 as needed, and printed matter is completed.

  The printing apparatus scans and measures the pattern drawn by the optical sensor, calculates a position error, and applies the position error to the bonded pattern basic data to create bonded pattern correction data. And since an adhesive layer is formed according to adhesive pattern correction data, it becomes a printing apparatus which can print the printed matter which the position accuracy of the pattern and the adhesive layer (and metal glossy area) improved more.

  Further, the pattern recording head and the adhesive pattern recording head are driven independently, and the maintenance, inspection, and maintenance of the adhesive pattern recording head are easy.

  Furthermore, it is possible to print a printed matter in which the positional accuracy of the pattern and the adhesive layer (and hence the metallic gloss region) is improved due to the optical sensor and the adhesive pattern recording head being driven as a unit. That is, even if the drive mechanism of the optical sensor and the adhesive pattern recording head has a deviation, the deviation is added at the time of measuring the picture coordinates and subtracted at the time of forming the adhesive layer, thereby canceling them. Here, the deviation means, for example, a phenomenon in which the actual movement amount of the adhesive pattern recording head is larger (or smaller) than the set movement amount recorded in the operation unit.
