Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to an ink-jet printing system for printing on a printing material formed of a cloth product such as a T-shirt.

[0002]

2. Description of the Related Art Conventionally, images (including characters and symbols) are applied to cloth products such as T-shirts (for example, clothes as cotton products).
Screen printing, iron printing (transfer printing), and the like are known as methods for printing. In the screen printing, a paste paste colored by mixing a pigment is applied to a material to be printed (object to be printed) through a transparent portion formed in a predetermined pattern on a screen, and the paste is applied by utilizing a bonding force of the paste. This is carried out by a method in which the paste is fixed to the printing example. When multi-color printing is performed by this screen printing, over-coating is performed using a plurality of screen plates corresponding to each color.

[0003] On the other hand, the iron print is a method in which an image material is printed on transfer paper by a color toner copying machine or an ink jet printer or the like, and then the printed transfer paper is hot-pressed to a cloth product such as a T-shirt (clothes).
This is carried out by a method of transferring to Also, recently, after directly printing the image on the pre-treated cloth using an inkjet printer, and after performing post-processing on the printed cloth,
A digital textile printing method performed in a process of sewing the cloth to finish clothing (cloth product) such as a T-shirt has also been implemented. Known documents disclosing such a conventional digital textile printing method using ink jet printing include JP-A-7-336466 and JP-A-8-2.
07263 and JP-A-8-207390.

However, in the above screen printing, a plurality of special editions corresponding to designs and colors are required, and the production time and cost are required. Not suitable for conversion. There is also a problem in that a large number of man-hours are required for storing and managing plates when printing (copying) the same image on a plurality of cloth products. Furthermore, the screen printing has a technical problem that it is difficult to print a high-definition image material.

On the other hand, in the above-mentioned iron printing, since the resin of the transfer paper is adhered to the surface of the printing material in the printing process, there is a technical problem that the printing material loses air permeability and the printing material becomes rough. There is. Especially T
When printing on clothes such as shirts, there is also a technical problem that clothes do not pass through sweat and the comfort becomes poor. Further, there is also a technical problem that the washing fastness of the printing material is deteriorated and the printing material is immediately ragged when washed. The above-mentioned digital textile printing method was devised in order to solve the above-mentioned drawbacks. However, in order to print on a material to be printed such as clothing made of fibers, post-processing such as pre-treatment, color-fixing treatment, washing, etc. In addition, it is necessary to sew the printing material printed as it is on the cloth to make a cloth product because of the difficulty of the processing method and the problem of the processing time. However, the conventional digital textile printing method has a technical problem that it is difficult to make it on-demand in a theme park or a tourist spot.

The present invention provides a small and inexpensive ink jet printing apparatus which can easily print on a cloth product such as a T-shirt on demand by solving such technical problems. That is, an object of the present invention is to stock a printing material in which only a specific printing target area is partially preprocessed as a standard stock product, and position the partial preprocessing portion of the printing material with respect to the inkjet printing mechanism during printing. By using a printing tray that conveys while printing, not only can you print directly on the material to be printed, but also it is not necessary to apply and dry a pretreatment agent during printing, making it easy to make print printing on demand. By doing so, it is possible to easily print on fabric products such as T-shirts on demand, not only to respond to requests for original prints, but also to print fabric products for commemorative goods at sightseeing spots, theme parks, etc. Another object of the present invention is to provide a small and inexpensive inkjet printing system that can create new demand.

[0007]

Accordingly, the above object can be achieved more efficiently by adopting a configuration in which the ink is prevented from seeping out to the back side of the printing material.

[0010]

Embodiments of the present invention will be specifically described below with reference to the drawings. In the following embodiment,
A description will be given by taking as an example a case where a cloth product as a material to be printed is a T-shirt which is a cotton product and the T-shirt is printed. FIG. 1 is a block diagram showing a process for printing an image material on a cloth product (T-shirt) by applying the present invention. In FIG. 1, the pretreatment is performed for the purpose of preventing ink bleeding and accelerating the reaction of the dye with a fabric fiber (such as cotton fiber).
Before printing the dye, T
A pretreatment agent is applied to a shirt or the like. The pre-treatment step includes application of a pre-treatment agent and drying as shown in the figure.

As a method of applying the pretreatment agent, a method of dipping is generally used, but a method of partial application using a spray or a sponge roller may be adopted. As the pretreatment agent, it is preferable to use a material in which at least one of a water repellent and a water-soluble resin contains a nonionic surfactant or an anionic surfactant. The water repellent and the water-soluble resin are used to suppress bleeding of an image and to fix a dye on the surface of a cloth (cloth) to improve coloring, and the nonionic surfactant and the anionic surfactant are used. Is to suppress the liquid medium in the ink from excessively penetrating in the thickness direction of the cloth and to improve the wettability of the dye to the cloth.

After pre-processing the print target area of the printing material (cloth product such as a T-shirt), a predetermined image material is printed (printed) on the print target area (partial pre-processing section) by an ink jet printing mechanism. You. Post-processing is further performed on the printed material to be printed. This post-processing comprises, as shown in the figure, the steps of color fixing, washing, fixing (FIX processing), drying and ironing. The color fixing is a reaction fixing step of a dye. Specifically, it is generally preferable to carry out a heating and coloring process as the reaction fixing step. As the step of the heat color development treatment, a conventional technique, for example, a known method used in a printing process is usually applied as it is. That is, a high-temperature steam method or a thermosol method is used.

The actual processing conditions in the heating color forming process (color fixing) are different depending on the type of cloth to be printed, but when cotton or silk cloth is dyed with an ink containing a reactive dye, high-temperature steam is used. The treatment is preferably performed at 100 to 105 degrees Celsius for 5 to 30 minutes by the method. When a polyester fiber cloth is dyed with an ink containing a disperse dye, it is treated at 160 to 180 degrees Celsius for several minutes to several tens of minutes by a high-temperature steam method, or at 190 to 230 degrees Celsius by a thermosol method. The treatment is preferably performed for several seconds to several tens of seconds.

In the washing step in the post-treatment, generally, a method of washing with water (including hot water) and then soaping with an aqueous solution containing a soaping agent or the like is used. However, if the material to be printed is polyester cloth,
After washing with water, a standard method is to perform reduction washing with an aqueous solution containing an alkali agent and hydrosulfide, and then further to wash with water. When the print material is a cotton cloth, washing is performed with water (including hot water), and then soaping is performed with an aqueous solution containing a soaping agent and the like. It is also possible to improve the washing fastness. In the fixing process, a dye fixing agent such as a fixing agent is used to improve washing fastness, and a process of removing excess dye is performed. As the fixing treatment agent, for example, a substance that converts the reactive dye into a poorly water-soluble compound form by binding to a hydrophilic group such as a sulfonic acid group of the reactive dye is used.A specific example of the substance is polyamine. Compounds, dicyandiamide compounds, and quaternary ammonium salt compounds.

FIG. 2 is a schematic plan view showing a partial pretreatment of a T-shirt as an example of a material to be printed (cloth product). In FIG. 2, reference numeral 1 denotes a T-shirt, and reference numeral 2 denotes a range of a partial pre-processing unit set on the chest of the T-shirt 1 (a range of a square in the figure). In general, most of the prints (printing of the art materials) on the T-shirt 1
The printing is performed within a fixed size such as 4 portraits / A4 landscape, etc., and a position and a size that almost satisfy these conditions are set as a print target range so that partial preprocessing is performed. It becomes possible. In particular, FIG.
In the above, the size of the partial pre-processing section (the area where the pre-processing of the chest was performed) 2 is set to be approximately A4 long square,
It can also handle horizontal / A4 vertical print materials.

As a method of partially applying the pretreatment agent in the pretreatment (FIG. 1), a method using a spray and a method using a sponge roller can be considered. FIG. 3 is a schematic view showing the concept of spray coating as a partial coating method for applying a pretreatment agent to a partial pretreatment section (print target range) 2. In FIG. 3, reference numeral 1 denotes a print-receiving material made of a cloth product such as a T-shirt, 2 denotes a partial pre-processing unit (print target range), 3 denotes a spray nozzle, 4 denotes a pre-treatment agent, Reference numeral 5 denotes a mask that covers a portion of the material to be printed (T-shirt) 1 that is not pre-processed (a portion other than the print target range). Reference numeral 5A denotes a mask that corresponds to the partial pre-processing unit 2 of the material to be printed 1. 3 shows the formed opening.

When the pre-treatment agent 4 is applied to the partial pre-processing section 2, a specific area of the printing material 1 (a range to be subjected to the partial pre-processing) is marked and displayed with a chalk pen or a sticker. Then, masking is performed with the mask 5 and a pretreatment agent may be applied thereon. If the pretreatment agent is applied by such a method, the marking mark by the chalk pen or the seal can be used as a mark for positioning on a printing tray to be described later. It becomes a positioning mark for (printer).

Further, instead of the method of making the partial pre-processing unit 2 recognizable by the marking with the chaco pen or the seal, the partial pre-processing unit is formed by partially pre-processing with a colored pre-processing agent. A method of making the partial pre-processing unit 2 identifiable may be adopted, and such a coloring identifying means can be used as a mark for positioning on a printing tray described below,
As a result, it can be used as a positioning mark for the printing material 1 with respect to the ink jet printing mechanism (printer).

FIG. 4 is a schematic view showing the concept of sponge roller coating as a partial coating method for applying a pretreatment agent to the partial pretreatment section 2. In FIG. 4, reference numeral 1 denotes a printing material made of a cloth product such as a T-shirt, 2 denotes a partial pre-processing unit (print target range), 6 denotes a sponge roller, 7
Indicates a screen stand. The screen base 7 has an opening 7A corresponding to the range and position of the partial pre-processing unit 2 of the printing material 1.

Advantages of the partial application of the pretreatment agent in the partial pretreatment are that the amount of the pretreatment agent used is minimized and the drying time is shortened. When the fabric product is a cotton product, shrinkage and distortion of the fabric product during drying can be minimized. The merits of spray coating are as follows. That is, printing by inkjet printing is generally dyeing only the surface of the cloth material, and therefore, by pre-treating only a specific portion of the surface of the cloth material by spray coating, the advantage of the partial coating is further emphasized. The bleeding of the pretreatment agent from the specific portion is eliminated, and the positioning on the printing tray and the specification of the portion to be cleaned can be performed easily and reliably. Of course, when it is required to print in a special size on a special portion of the printing material 1, the partial pre-processing section (printing range) 2 is individually spray-coated or sponge-rolled. Processing may be performed to prepare a printing tray (to be described later) having a shape corresponding to the location and size.

Therefore, an ink jet printing system according to the present invention comprises an ink jet printing mechanism capable of printing on a printing material such as a T-shirt or the like, and a printing target area of the printing material which is held in a plane. A T-shirt that has a printing tray that conveys the print target area while positioning the print target area with respect to a printing mechanism, and a partial preprocessing section that is formed by partially preprocessing only the print target area, and is stocked as a standard product. And a print-receiving material made of a cloth product such as the above.

FIG. 3 is a schematic perspective view showing a state in which a print-receiving material (T-shirt) is mounted on the print medium. 5 and 6, the printing tray 11 has a structure in which the lower plate 12 and the upper plate 13 are connected to each other with the support pillars 14 so as to be formed in an overall shape. The upper plate 13 is formed in a flat shape so that the cloth material 1 such as a T-shirt, which is a material to be printed, can be placed and mounted (mounted) on the upper surface thereof. The size of the upper plate 13 (the width of the upper surface) is substantially the same as that of the partial pre-processing section 2 of the print-receiving material 1, so that the upper area of the printing tray 11 is minimized. Can be set to If the partial pre-processing unit 2 of the print material (T-shirt) 1 is marked (marked by washing and dropping) with a pen or a sticker, the print material 1 is easily positioned and mounted on the printing tray 11. be able to.

Further, the printing tray 11 holds the partial pre-processing portion (printing target area) 2 of the printing material 1 in a planar shape as described above, and
The printed material 1 is entirely shaped so that the print-receiving material 1 can be positioned and mounted on a printing tray in a state in which the other parts are included inside. That is, the printing tray 11
Arm 17 of T-shirt (printed material) 1
The printing tray 1 on which the printing material 1 is mounted by including the non-printing portions such as the neck portion 18 and the hem portion 19.
1 is designed so as to minimize the plane area and also to minimize the inkjet printing mechanism.

The size (width) of the upper plate 13 is as follows:
It is good that the dimensions can be changed according to the size of the printing material 1 such as a T-shirt for children and a T-shirt for adults. The size of the lower plate 12 may be the same, and the support 14 is provided at a displaced position in the printing tray 11 to make it easy to cover the printing material 1 such as a T-shirt. The material of the printing tray 11 is not particularly limited, and a desired material such as wood, plastic, and metal can be used. Further, if the shape of the printing tray 11 is made into the above-described construction shape, and the printing material (T-shirt) 1 is mounted on the upper plate 13 so as to cover the same, even in the case of a thin printing material, When printing (printing) an image material on a printing material, it is possible to prevent the ink from seeping out to the back side of the printing material 1.

FIG. 7 is a schematic perspective view showing an embodiment of an ink jet printing mechanism (printing printer) used in the ink jet printing system to which the present invention is applied. In FIG. 7, the inkjet printing mechanism 31
Is for printing (inkjet printing) a desired image material directly (directly) on the material 1 to be printed. The printing tray 11 (see FIG. 6) on which the printing material 1 such as a T-shirt is mounted is transported through the inkjet printing mechanism 31 by a transport belt 33 installed on a transport table 32. In the meantime, a desired range of the printing material 1 positioned and mounted on the printing tray 11 (specifically, the partial pre-processing unit 2 supported in a planar manner on the upper surface of the upper plate 13 of the printing tray 11). On the other hand, a predetermined image material is printed by the ink jet printing mechanism 31 (the dye ink discharged from the ink jet head or the ink discharge port).

The ink jet printing mechanism 31 includes:
As shown, it has a substantially gate-shaped print section, and an ink jet unit (not shown) is disposed inside the top beam 31A. The ink jet unit prints an image on a print target area (partial pre-processing unit) 2 of a printing material 1 by discharging ink from a discharge port based on image information. The print unit includes a print head 1 that is reciprocated in a direction intersecting the transport direction of the print material 1 and that is driven by a main scan.
A serial printing type in which an image is formed by alternately repeating line printing and pitch feeding (pitch conveyance) of the printing material 1, and a line type having a predetermined length in the width direction of the printing material 1 There is a line print type in which printing is performed only by pitch feed (sub-scanning) in the transport direction of the print-receiving material 1 using the print head. Known documents that disclose such an ink jet printing mechanism include JP-A-8-207263 and JP-A-8-207390.

Printing tray 1 on which printing material 1 is mounted
The transfer of 1 is performed by the following mechanism. That is, the guide of the printing tray 11 in the width direction with respect to the carrier 32 is formed by the lower plate 12 of the printing tray 11 and the carrier 3.
2 with a width guide (not shown). In addition, the print tray 11 is caught in the transport direction in the lower plate 1 of the print tray 11.
2 is detected by a detection switch (not shown) provided on the transfer table 32. Printing tray 1
1 is detected, the transport table 32 is detected.
Is moved upward until the partial pre-processing unit 2 of the printing material 1 disposed on the upper plate 13 of the printing tray 11 contacts an upper surface detection switch (not shown) of the inkjet printing mechanism 31. Thereby, the gap between the partial pre-processing unit (print target range) 2 and the inkjet head is adjusted. After performing the gap adjustment, the apparatus enters a print mode in which the dye ink is ejected from the inkjet head to print an image material on the partial preprocessing section.

As described above, by positioning the printing tray 11 with respect to the ink jet printing mechanism 31, the ink jet printing mechanism 31 (the ink jet head or the discharge port) of the printing medium 1 mounted on the printing tray 11 is used. Can be positioned. When printing on the printing material 1 is completed, the transfer table 32
Is lowered to the original standard height, and the printing tray 11 on which the print material 1 is mounted is discharged from the transport base 32.

The ink-jet print (print head) is constituted by ink-jet means having an electrothermal converter for generating thermal energy used for discharging ink. The ink jet means performs printing by discharging ink from a discharge port using film boiling generated in the ink by thermal energy generated by the electrothermal transducer.

FIG. 9 is a partial perspective view schematically showing the structure of an ink ejection section of a serial print type ink jet unit. In FIG. 9, a plurality of discharge ports 82 are formed at a predetermined pitch on a discharge port surface 81 facing the print material 1 with a predetermined gap (for example, about 0.3 to about 2.0 mm). An electrothermal converter (heating resistor, etc.) 85 for generating energy for ink discharge is provided along the wall surface of each liquid path 84 formed and communicating the common liquid chamber 83 and each discharge port 82. ing. The ink jet unit (print head) is mounted on, for example, a main scanning carriage in such a positional relationship that the discharge ports 82 are arranged in a direction crossing the main scanning direction. In this way, the corresponding electrothermal transducer 85 is driven (energized) based on the image (print signal) or the ejection signal to cause the ink in the liquid path 84 to boil, and the pressure generated at that time causes the ink from the ejection port 82 to be discharged from the ejection port 82. The ink jet unit which discharges is constituted.

FIG. 8 is a conceptual diagram showing a method for inputting, printing, and processing files on a printing material to be printed on a printing material by a personal computer. In the ink jet textile printing system to which the present invention is applied, a display surface capable of displaying only the partial pre-processing portion (printing target range) 2 of the print material 1 as a print material arrangement area, and a digital image material arranged on the display surface Image input / output means capable of printing the digital image material. That is, in FIG. 8, a partial pre-processing unit (a range where a pre-processing agent is applied) is provided on each screen of the displays 41A and 41B.
2 are displayed, and the image materials 43A and 43B are arranged therein. Therefore, one of the print range frames 42A and 42B is selected and printed.
Then, the image material displayed in the selected print range frame among the image materials 43A and 43B is printed in the partial pre-processing unit 2 of the print target material (T-shirt or the like) 1 in the state displayed in the print range frame. Is done.

When the print information is filed, the file is configured to be able to be filed, including image information such as an image material to be printed, a print position, and a print size, in addition to the customer order information. According to such a configuration, it is possible to easily realize the duplication of the print on the print material 1 as it is, or the duplication with a partial modification. Therefore, when printing on demand at a sightseeing spot or a theme park, etc., the customer and the print area frame 42A,
By simply arranging and setting images (art materials) while interacting with the user while watching 42B, it is possible to easily and reliably print the art materials desired by the customer.

According to the embodiment described above, it is possible to print directly on a cloth product such as a T-shirt in an on-demand manner and easily and reliably print on-demand painting materials at a tourist spot or a theme park. The present invention provides an ink-jet printing system capable of responding to the following. That is, the printing material 1 in which only the specific print target area 2 is partially pre-processed is stocked as a standard stock, and the partial pre-processing unit 2 of the printing material 1 is positioned with respect to the inkjet printing mechanism 31 during printing. By using the printing tray 11 to be conveyed, not only can the printing material 1 be printed directly, but also the printing and printing process can be made on-demand by eliminating the steps of applying and drying a pretreatment agent during printing. This makes it easy to print on T-shirts and other cloth products 1 on demand, not only to respond to the demand for original prints, but also to make commemorative goods cloth products at sightseeing spots and theme parks. A small and inexpensive inkjet printing system that can create new demand for printing and the like is provided.

Further, since the range to be printed (the range of the partial preprocessing section) is specified and standardized, the same preprocessing can be performed in a large amount, and the cost of the preprocessing can be greatly reduced. In addition, compared to the conventional printing technique of immersing the entire print material consisting of a cloth product such as a T-shirt, the amount of the pretreatment agent can be reduced to a minimum, and after the pretreatment agent is applied. Since the drying time after washing or the like can be shortened, the effect of minimizing shrinkage and twist when drying a cloth product such as a cotton T-shirt can be obtained. In addition, since the color fixing and the cleaning can be partially processed only for the specific portion, the color developing device and the cleaning device can be reduced in size and cost, and the post-processing time can also be reduced. Since it is possible to simultaneously carry out partial cleaning, it is possible to minimize the shrinkage or shrinkage of the collar and sleeves, etc., which occur during drying, especially in the case of cotton T-shirts.

Further, by marking the pre-processed portion (partial pre-processing portion) 2 with a charcoal pen, a sticker, or the like, or by partially pre-processing with a colored pre-processing agent, the range of the partial pre-processing portion 2 can be easily adjusted. Since the size of the printing material mounting portion of the printing tray is substantially the same as the size of the marking or coloring portion, the positioning of the printing tray on the printing tray becomes easy, and the inkjet printing mechanism Positioning becomes easy. Ink-jet printing is generally dyeing only the surface of the cloth material, so by pre-treating only the surface of the cloth product by spray coating or the like, the advantages of partial coating only in the pre-treatment section are emphasized, The bleeding of the pretreatment agent from the partial pretreatment section (print target area) can be eliminated, and the positioning of the pretreatment agent on the printing tray can be performed more easily and accurately.

In addition, since digital printing is performed by using an ink jet printing mechanism, any digital image material can be printed on the spot without a plate, and on-demand printing can be further facilitated. Also, since the print range to be partially pre-processed is substantially a square of A4 length, it can be used for both A4 landscape and A4 length print art materials without changing the method of mounting the print material on the print tray. Can be. Furthermore, the ink jet printer can exhibit a high-definition printing function, which is a feature of an ink jet printer, and can also exhibit features such as good texture at the time of finishing by textile printing and good washing fastness.

In addition, printing is performed on a printing material in which only a specific print target area is partially pre-processed while the printing position of the partial pre-processing section is adjusted using a printing tray. Provides an inkjet printing system that can minimize the size of only the partial pre-processing section, thereby enabling the printing mechanism to have a minimum size and an inexpensive structure, and can be easily placed in stores and the like. Is done. In addition, since printing is directly performed by an ink jet printing mechanism on a printing material such as a standard T-shirt or the like cloth (clothing or the like), not only the on-demand operation is facilitated, but also a standard cloth or the like. An ink jet textile printing system is provided in which a material to be printed is obtained, and a pretreatment is performed on the material to be printed according to demand, thereby solving the problem of excess stock.

Further, by using only a specific print target area as the partial pre-processing section, the cleaning step can be performed by a small cleaning means capable of cleaning only the partial pre-processing section. An ink jet textile printing apparatus is provided which can perform the process only by the treatment of the partial pretreatment section alone, and can facilitate the textile printing process and downsize the textile printing apparatus.

Further, the partial pretreatment portion of the material to be printed made of a cloth product such as a T-shirt can be easily flattened and positioned with respect to the printing mechanism, and the printing material can be accurately printed at a specific position. Is provided. Further, there is provided an ink jet textile printing apparatus capable of eliminating stains due to ink or the like on a printing material by concealing a non-printing portion inside a printing tray.

Thus, according to the above-described embodiment, T
A system that can print high-definition digital art materials on shirts and other cloth products (clothing) without plates and on demand can be easily constructed with a small, inexpensive configuration, and can only respond to the demands of original printing. Instead, there is provided an ink jet textile printing system that can create new demand for printing T-shirts and the like for commemorative goods at sightseeing spots and theme parks.
