<Printing device 50>
In this embodiment, the printing device 50 includes a carriage 51, a carriage moving device 52, an inkjet head 53, and a light irradiation device 54.

The carriage 51 is a member on which the inkjet head 53, the light irradiation device 54, and the like are mounted. In the printer 10 having a function of cutting the printed matter 5, a cutter may be mounted on the carriage 51, which is not included in FIG. In this embodiment, the inkjet head 53 and the light irradiation device 54 are mounted on one carriage 51, but are not limited thereto. For example, a plurality of carriages 51 may be prepared, and the inkjet head 53, the light irradiation device 54, the cutter, and the like may be mounted on separate carriages.

The carriage moving device 52 is a device for moving the carriage 51. The carriage moving device 52 includes a guide rail 52a and a belt 52b. In this embodiment, the guide rail 52a is a straight rail, and is arranged above the flatbed 41 in the housing 11 so as to extend along the main scanning direction Y. Pulleys 52c and 52d are provided at both ends of the guide rail 52a. The carriage 51 is slidably attached to the guide rail 52a. The belt 52b is an endless belt. The belt 52b is hung around pulleys 52c and 52d provided on the right side and the left side of the guide rail 52a. A carriage motor 52e is attached to a part of the pulley (pulley 52d in the illustrated example) provided on the guide rail 52a. The pulley 52d functions as a drive pulley for driving the belt 52b. When the belt 52b is driven, the carriage 51 moves along the guide rail 52a in the main scanning direction Y. A servomotor is adopted for the carriage motor 52e, and it is preferable that an encoder is attached to the carriage motor 52e. By controlling the carriage motor 52e based on the information obtained from the encoder, the carriage 51 can be moved to a predetermined position along the guide rail 52a. The carriage 51 is scanned over the flatbed 41 along the guide rail 52a.

The inkjet head 53 is a head that ejects ink. The inkjet head 53 is attached to the carriage 51 so that the ink ejection surface faces the flatbed 41 when the carriage 51 is scanned along the guide rail 52a. The inkjet head 53 forms ink dots of a plurality of types of ink including process color ink and spot color ink on the printed matter 5. The inkjet head 53 includes a plurality of heads 61 to 64. The plurality of heads 61 to 64 are attached to the carriage 51 so as to eject ink toward the flatbed 41.

Although not shown, the first heads 61 to 64 are mounted on the carriage 51 so as to be aligned with the main scanning direction Y. Each of the first heads 61 to 64 extends in the sub-scanning direction X. The plurality of heads 61 to 64 are not limited to such a form. The plurality of heads 61 to 64 may be arranged in a so-called stagger, and the position of the sub-scanning direction X of some heads may be deviated from the position of the sub-scanning direction X of the other heads. The number of heads included in the inkjet head 53 is four here. The number of heads is not limited.

The first heads 61 to 64 each include a plurality of nozzles arranged in the sub-scanning direction X. The nozzle is a fine hole into which ink is ejected. The nozzles communicate with each other in the pressure chamber where the ink is stored. The ink is ejected from the nozzle by expanding / contracting the pressure chamber by driving an actuator such as a piezoelectric element. The first head 61 to the fourth head 64 of the inkjet head 53 include, for example, a plurality of nozzle rows (for example, two rows) in the main scanning direction Y. In the plurality of nozzle rows, a plurality of nozzles are arranged in the sub-scanning direction X, respectively. Each nozzle in the plurality of nozzle rows ejects ink in the ink cartridge 71 connected to each nozzle. Each ink that lands on the printed matter 5 forms an ink dot.

As shown in FIG. 2, the ink cartridge 71 is housed in the ink cartridge housing section 72. A plurality of ink cartridges 71 are accommodated in the ink cartridge accommodating portion 72. Each of the plurality of ink cartridges 71 contains predetermined ink. As the inks prepared in the plurality of ink cartridges 71, for example, cyan ink, magenta ink, yellow ink, and black ink (CMYK) are prepared as process color inks. Process color inks are not limited to CMYK. For example, in order to improve the color development, a light color ink such as light cyan, orange, light black (light black), or the like may be used as the process color ink. Further, as the spot color ink, white ink, primer ink, gloss ink, metallic ink and the like can be included.

White ink is an ink for improving the color development of white. The white ink is used, for example, to form a white base layer on a transparent printed matter or a colored matter other than white. The primer ink is an ink for improving the adhesion between the printed matter 5 and the ink. The primer ink is an ink used for an undercoat as appropriate, and is referred to as an undercoat ink, a base ink, or the like. Gloss ink is a transparent ink. Gloss ink is used, for example, in a top coat that covers a main image (for example, an object to be displayed such as a character, a figure, a photograph, etc.). Gross ink may also be used, for example, to form a three-dimensionally formed texture pattern. For example, when a texture pattern is formed by gloss ink as a base layer, a visual effect that the color tone of an image or the like is partially changed by the texture pattern can be obtained. The metallic ink is an ink for improving the color development of a metallic color. Further, the ink ejected from the inkjet head 53 may be a photocurable ink. The photocurable ink here is an ultraviolet curable ink that cures when irradiated with ultraviolet rays. The components, characteristics, etc. of the photocurable ink are not particularly limited.

The light irradiation device 54 is fixed to the carriage 51. Here, the light irradiation device 54 is provided on the left side of the inkjet head 53. The light irradiation device 54 irradiates the light that cures the photocurable ink toward the printed matter 5 on the flatbed 41. The light source of the light irradiation device 54 may be composed of, for example, a plurality of ultraviolet irradiation LEDs. The irradiation port of the light irradiation device 54 may extend in the sub-scanning direction X, for example.

In the flatbed type printer provided with such a flatbed, the carriage 51 is scanned in the main scanning direction Y while the printed matter 5 on the flatbed 41 is sent in the sub-scanning direction X at a predetermined speed, and is ejected from the inkjet head 53. The ink to be printed is landed at a predetermined position on the object to be printed 5. As a result, printing along the surfaces defined by the main scanning direction Y and the sub-scanning direction X is performed on the printed matter 5.

In professional applications such as commercial printing, multiple layers of printing may be layered in order to express unevenness, glossiness or matteness of the surface. In this case, a method in which a plurality of layers are printed on the printed matter 5 in one scan when the carriage 51 is scanned in the main scanning direction Y, and the flatbed 41 is returned to a predetermined position to print the printed matter 5. There is a method of printing multiple times in the same place. For example, as a printing method for improving the appearance of a photograph, there is a case of printing on a transparent vinyl chloride medium or an acrylic plate while lining a white background. In such an application, there is overlay printing in which white is printed on a base and an image such as a photograph is printed on the white. Furthermore, by printing a gloss on top of it, the surface of the printed photograph can be given a glossy finish.

When printing three layers of a base layer, a drawing layer, and a finishing layer in an overlapping manner, in the method of simultaneous printing, for example, the carriage 51 is scanned in the main scanning direction Y while being fed at a predetermined speed in the sub scanning direction X, and inkjet is performed. The ink discharged from the head 53 is landed on the printed matter 5. At this time, the flatbed 41 is sent from the back to the front along the sub-scanning direction X. The nozzle on the back side of the inkjet head 53 in the sub-scanning direction X prints the base layer. The nozzle in the middle portion of the inkjet head 53 prints the drawing layer. The nozzle on the front side of the inkjet head 53 prints the finishing layer. As a result, the inkjet head 53 is scanned once, so that the three layers of the base layer, the drawing layer, and the finishing layer are printed on top of each other. In a method in which the flatbed 41 is returned to a predetermined position and printing is performed on the same place of the printed matter 5 a plurality of times, the base layer, the drawing layer, and the finishing layer may be printed in order. Here, the printing method of the flatbed type printer is exemplified. Here, the printer is not limited to the flatbed type printer. For example, even in a large roll-to-roll printer, when printing three layers of a base layer, a drawing layer, and a finishing layer in layers, there are cases where printing is performed at the same time and a method of pulling back the roll to print a plurality of layers. ..

Here, the structure of the printer 10 shown in FIGS. 1 and 2 has been described. The structure of the printer 10 is not limited to the above-mentioned form unless otherwise specified.

The control device 13 is arranged in the housing 11 of the printer 10. The printer 10 includes an operation unit 14. In the example shown in FIG. 1, the operation unit 14 is composed of an operation panel such as a touch panel display. The operation unit 14 is not limited to such a configuration.

The control device 13 is a device that controls various processes of the printer 10. The control device 13 can be embodied by a computer driven according to a predetermined program. Specifically, each function of the control device 13 includes a computing device (also referred to as a processor, a CPU (Central Processing Unit), or an MPU (Micro-processing unit)) or a storage device (also referred to as a processor, a CPU (Central Processing Unit), or an MPU (Micro-processing unit)) of each computer constituting the control device 13. It is processed by memory, hard disk, etc.). For example, each configuration of the control device 13 may be a database that stores data embodied by a computer in a predetermined format, a data structure, a processing module that performs predetermined arithmetic processing according to a predetermined program, or the like. It can be embodied as part of them.

FIG. 3 is a block diagram of the control device 13. As shown in FIG. 3, the control device 13 includes a storage unit 13a for storing information, a processing unit 13b for executing various processes such as arithmetic processing, and a communication unit 13c for communicating with an external computer 200. And have. The control device 13 is connected to the printing unit 12 and the operation unit 14. In this embodiment, the control device 13 includes a first storage unit 13a1, a second storage unit 13a2, a first processing unit 13b1, and a second processing unit 13b2.

The first storage unit 13a1 stores print data in which print contents are defined. The print data may be, for example, data created by RIP software. The control device 13 appropriately communicates with the external computer 200 and stores the printed data in which the transferred print contents are defined.

Here, the external computer 200 is a computer for preparing print data. The external computer 200 incorporates DTP software and software that performs RIP processing. The print data is raster image data created by DTP software or software that performs RIP processing. Raster image data is a data reproduction method that expresses an image as an enumeration / set of dots called colored dots.

The control device 13 controls the printer 10 based on the information sent from the external computer 200, for example, and executes the printing process. Software (program) called firmware is mounted on the control device 13 so as to be usable. The control device 13 is configured to execute various processes for controlling the printer 10 by the firmware. Print data is sent from the external computer 200. The print data is the raster image data described above. Based on the raster image data, for example, what color of ink is ejected to a predetermined position (predetermined dot) of the printed matter 5 and in what amount is determined. An image represented based on the raster image data sent from the external computer 200 is drawn on the printed matter 5 by the firmware mounted on the control device 13.

The first processing unit 13b1 is configured to execute a process of preparing at least one overlay print data. The overlay print data is, for example, data in which the print content to be printed over the print content defined by the print data stored in the first storage unit 13a1 is defined. By the processing of the first processing unit 13b1, the printer 10 can add the data of the print layer to be overprinted to the printing by the printing data sent from the external computer 200. The print layer to be printed in layers includes a base layer and a finish layer. The overlay printing data may be data such as base printing and finish printing. The printer 10 can add a base layer or a finishing layer to an image represented by an external computer 200 based on the prepared raster image data.

When the overprint data is prepared for the print data stored in the first storage unit 13a1, the second processing unit 13b2 prepares the overprint data and prints stored in the first storage unit 13a1. It is configured to execute a process of controlling the printing unit so that overlay printing is performed based on the data. When the overlay print data is not prepared for the print data stored in the first storage unit 13a1, the process of controlling the print unit based on the print data stored in the first storage unit 13a1. Should be executed.

The overlay printing data may include, for example, at least one of the base print data printed below the print data and the finish print data printed on the print data. A plurality of background print data to be printed may be prepared below the print data. In this case, it is preferable that the printing order is specified in the plurality of prepared background print data. A plurality of finish print data to be printed on the print data may be prepared. In this case, it is preferable that the printing order is specified in the plurality of prepared finish print data. Further, only the base print data may be prepared, or only the finish print data may be prepared.

In this case, for example, the raster image data sent from the external computer 200 is stored as print data in the first storage unit 13a1. On the other hand, in the control device 13 of the printer 10, the overlay printing data can be added by the first processing unit 13b1. Therefore, in order to add overlay printing data and perform overlay printing, it is not necessary to return to the external computer 200 and edit the raster image data on the external computer 200. Further, it is not necessary to transfer the edited raster image data from the external computer 200 to the printer 10. Further, the process of preparing such overlay printing data can be set in the control device 13 on the printer 10 side. For this reason, for example, when there is a special base print or finish print prepared as a function peculiar to the printer 10, overprint printing is performed for a special print which is not prepared by the software installed in the external computer 200. It can be configured so that it can be added as data. For example, a texture pattern having a special shape that can be realized as a unique function of the printer 10, printing using a special ink prepared in the printer 10, and the like can be added as overlay printing data by an operation on the printer 10 side. .. As described above, according to the printer 10, the print data stored in the first storage unit 13a1 is not edited by the operation on the printer 10 side by the control device 13 arranged in the housing 11 of the printer 10. 1 Appropriate overlay printing can be added to the print data stored in the storage unit 13a1.

By including the base print data to be printed under the print data, the base print is added to the print data stored in the first storage unit 13a1. For example, when it is desired to add a white background to the drawing based on the print data stored in the first storage unit 13a1, the background print data for printing the white background is prepared as overlay printing data. It is good. Further, when the surface of the object to be printed 5 is raised or a three-dimensionally formed texture pattern is formed by using the prima ink as the base, the base print data by the undercoat printing with the prima ink or the photocurable ink is used. , It is preferable to prepare it as overlay printing data. Further, finish printing data by gloss printing may be prepared as overlay printing data in order to give a glossy feeling to the surface. As described above, the drawing itself based on the print data stored in the first storage unit 13a1 does not change. Since the overlay print data can be appropriately added by the operation on the printer 10 side, the impression of the drawn printed matter can be greatly changed. Further, after the printed matter drawn based on the print data stored in the first storage unit 13a1 is trial-printed, the overlay printing can be adjusted on the printer 10 side. Therefore, the labor of fine-tuning the base printing and the finish printing is greatly reduced.

The second storage unit 13a2 stores at least one print content of a predetermined pattern. In this case, the first processing unit 13b1 is configured so that the print content of the overlay print data can be selected from at least one print content stored in the second storage unit 13a2. It is said that the second storage unit 13a2 is prepared with a predetermined pattern such as ink, darkness, texture pattern, etc. to be used, for example, undercoat printing, undercoat printing with primary ink, finish printing with gloss ink, and the like. good. By combining these, the overlay printing data can be easily set.

As described above, the printing unit 12 of the printer 10 includes a stage 40 on which the printed matter 5 to be printed is arranged, and a printing device 50 that prints on the printed matter 5 arranged on the stage 40. There is. Whether or not the control device 13 prepares the overlay print data at a predetermined timing from the preparation of the printed matter 5 on the stage 40 to the printing of the print data stored in the first storage unit 13a1. It is preferable that the selection process (S14) for selecting the data is executed (see FIG. 4).

The timing at which the printed matter 5 is prepared on the stage 40 may be, for example, the timing at which the printed matter 5 is set on the flatbed 41 in the case of the above-mentioned flatbed type printer. Further, it may be the timing when the flat bed 41 on which the printed matter 5 is set moves to a predetermined start position. Further, although not shown, in the case of a roll-to-roll printer, the timing may be the timing at which the roll as the printed matter 5 is set. Further, in the roll-to-roll printer, rolls are intermittently sent to perform continuous printing. Therefore, it may be the timing at which the printed matter is cut and the printer is waiting before the next printing is started.

FIG. 4 is a flowchart showing an example of the processing procedure of the control device 13. FIG. 5 is a flowchart showing an example of a procedure for setting overlay print data in the first processing unit 13b1.

For example, as shown in FIG. 4, the control device 13 stores print data in the first storage unit 13a1 (S12). The print data may be, for example, transferred from an external computer 200 as described above. The control device 13 inquires whether or not to perform overprinting at a predetermined timing (S14). For example, when printing is performed based on the print data stored in the first storage unit 13a1, even if the operation unit 14 displays a screen asking whether to perform overlay printing before printing is started. good. Here, the user who operates the printer 10 may select whether or not to set overlay printing. When setting the overlay printing is not selected (No), for example, printing based on the print data stored in the first storage unit 13a1 may be executed (S16). When it is selected to set overlay printing (Yes), for example, overlay printing is set (S18). After that, overlay printing is performed (S20). That is, the set overlay printing and the printing based on the print data stored in the first storage unit 13a1 are executed in a predetermined order. As a result, the base print and finish print desired by the user who operates the printer 10 are overprinted on the print based on the print data stored in the first storage unit 13a1. Thereby, the impression of the drawing printed based on the print data stored in the first storage unit 13a1 can be appropriately changed by the operation on the printer 10 side without changing the print data.

Here, the process of setting the overlay printing (S18) is, for example, as shown in FIG. 5, a process of setting the number of base layers (S22) and a process of setting the number of finish layers (S24). It is preferable that the process (S26) for setting the printing of each layer of the base layer and the finish layer is performed. This makes it possible to set a plurality of base layers and a plurality of finish layers. In addition, appropriate printing can be set for each layer. The order in which the base layer is printed and the order in which the finish layer is printed may also be set.

As described above, some suitable embodiments of the printer 10 disclosed here have been described. However, the printer according to the present invention is not limited to the above-described embodiment.
