Description

TECHNICAL FIELD The present invention relates to a method for printing and a blind apparatus using a water-insoluble ink. The present invention relates to a demand for short delivery time and small-lot production. Printing on paper or cloth has been a typical example. The mainstream development of inks used is aqueous inks. There are aqueous dyes that dye on materials and aqueous pigments that adhere to the surface of the materials: These aqueous inks By using, it became possible to produce a hoster and fabric of a single product printed on paper or cloth based on image data from a computer. Despite trying to achieve delivery and small-lot production, the problem is that it is difficult to achieve with existing inkjet system Found: Water-insoluble inks compatible with synthetic leather and natural leather have not been found in previous systems, and only as a future possibility, the front and back treatment of the leather blinded surface It was only anticipated that an improvement in the method of applying a water-based dye and coloring, or coloring a semi-finished product and subjecting it to post-treatment to obtain a finished product, was expected.

For example, a blind system using a basic dye as a water-based dye is conceivable.If the system using this basic dye is intended to be applied to leather, the printed surface of the leather is not suitable for the basic dye. There is no pre-processing, leather replacement paper (Rule 26) In addition to the usual leather surface treatment, a binder layer is formed on the surface to be printed, and an aqueous dye is applied to the binder layer to color it, and the dye is fixed by heat treatment or chemical treatment as a post-treatment to improve water resistance. An additional fixing process is required. In addition, various post-treatments are required, such as a soaking step to remove residual dye and a coating step to form a film to prevent water intrusion-or a method that does not form a binder layer as a pre-treatment In order to use the leather, it is necessary to add an unusual process to the leather manufacturing process of extracting the leather as a semi-finished product, and not to apply a coating process on the surface of the leather that almost eliminates the impregnation with aqueous substances. It does not become a product that can withstand: Aqueous dyes, as shown in (2), require a pre- and post-processing step, and are effective in the case of continuously producing a large number of conventional leathers of the same specifications. Short-term delivery, not a method that can efficiently respond to small-lot production

In addition, even if the water-soluble pigment tire ink is improved, it will be difficult to achieve short delivery times and small-lot production to the leather field, as with the above-mentioned water-based dyes, because it requires the preceding and following processing steps. ..

In the field of printing on fabric, there is a printing method using sublimation diffusion called sublimation printing with an ink jet printer, which has been developed in recent years.However, the material printed on transfer paper with an ink jet printer is heated by applying heat. If the material is leather, it will be denatured by heat and the texture will be impaired. Also, as a method using an ink jet printer, a film such as high molecular gelatin is formed on the material and then the film is coated with water. There is also a method of printing dyes, but it requires various processing steps such as finishing coating to provide durability against water and friction, and is still not a method that can sufficiently respond to the required short delivery time and small-lot production: Disclosure Replacement Form (Rule 26) The present invention has been developed at least for short-term delivery and small-lot production to the field of leather, namely, shoes, and provides a method and a blind apparatus using a water-insoluble ink.

Further, the present invention provides a blind method and a blind apparatus using a water-insoluble ink which have excellent color fastness properties and can omit or simplify the usual pre-processing and post-processing steps.

FIG. 5 is a table showing the results of testing the fastness of dyeing. BEST MODE FOR CARRYING OUT THE INVENTION As an object of the flint of the present invention, a synthetic leather in which polyurethane is present on the surface layer will be described as an example particularly.

An embodiment of the present invention will be described below. The following embodiment is a system for manufacturing an upper of a women's shoe or the like by using an on-demand system for each item: The present invention is limited to this example. Not something that is done:

The on-demand system according to the present embodiment realizes small-lot production in which the upper of a women's shoe is manufactured one step at a time in a desired design. Further, it is possible to select a desired shoe style and add value. Fig. 1 shows a block diagram of the system. Fig. 1 is a block diagram of the system. Have a lab link

The pasted image creating means creates data in which previously stored pattern data and / or newly input pattern data is pasted to the appearance of a three-dimensional image of a desired object. It is connected to the database and the database of pre-registered stereo image data. The stuck image created by the stuck image creation means is selected as the appearance data of the selected shoe as shown in Fig. 2. Replacement sheet (Rule 26), which is based on the appearance of the completed shoe with the designed pattern data attached Is

The pattern data database stores a plurality of pattern patterns suitable for the design of the shoe upper. Also, the database of the three-dimensional image data is to store a plurality of data of the appearance image of the shoe in a plurality of categories. The appearance image data of multiple parts of the shoe, such as the shape and height of the shoe, the presence or absence of a ribbon as a decoration, and the design of the ribbon, are classified and stored. The appearance image data of each part of the shoe is stored. The combination will determine the appearance image of the entire shoe of your choice. ・ The appearance image data is representative of the gloss of the material so that the user can confirm the finish more quickly. It is also desirable to include data on the texture and texture of the material: In addition, the appearance image data may include multiple embossed patterns. The selected embossing pattern is applied to the material after direct printing by this printing device: This allows you to check the appearance image of the shoes with the embossed texture prior to production. In addition to the external appearance image described above, expanded structural data necessary for sewing a shoe having the external appearance may be prepared. As the expanded structural data, type data of the upper or the like (cutting) Line data) can be classified and registered as a pair of data. For design data and stereoscopic image data, new data can be registered in addition to the already registered data.

The display means displays the stuck image created by the stuck image creation means. For example, the stuck image shown in FIG. 2 is displayed:

The relationship determining means adjusts and determines the relative relationship between the design data and the three-dimensional image based on the pasted image displayed by the display means. FIG. 3 shows a state in which the type data and the design data as the structural data in the three-dimensional data are positioned and relatively related. Replacement sheet that can be placed in any position by means of relationship determination (Rule 26) Not only repetition of monotonous fine patterns and monochromatic designs, but also designs with high designability where the positional relationship is questionable, such as a flower pattern on the toe, a one-point pattern inside the heel, etc. Can be used. Of course, the position does not matter in detail, and the positioning of the relationship determining means may be rough, or the determination that the relationship is not determined may be included.

The blind data creating means is for creating error data obtained by combining predetermined structural data and design data in a three-dimensional pattern based on the relative relationship between the design data and the three-dimensional image determined by the relationship determining means: As shown in Fig. 3, the created print data is data for printing an image in which the related design data and type data are overlapped: the design data and the type data are overlapped. A single piece of blind data may be used, but composite data consisting of multiple sheets of design data and type data divided into layers may be used. In the case of a specification in which the relation determining means does not determine the relation, The data does not need to be included in the print data: the print data does not need to be included in the print data. The placement data is data that determines the relative placement of the pattern data placed in the print area on the blinded surface. For example, the print area on the blinded surface is leather for one pair of shoes. Is set as a rectangular area of a size that can be cut, and if a single flower of a rose that comes to the toe is drawn in the design data, the design of a single flower of the rose is applied to the toe regardless of the shoe size. The pattern data is standardly arranged in the rectangular area so that the coming leather can be cut.

The layout data may be determined by the above-described relationship determining means: standard layout data may be registered in advance for each pattern data: According to this, even if there is no type data, the pre- When the design data is printed on the print area on the print surface, the relative placement between the print area and the print area is determined by the layout data. You can print designs such as floral patterns on the arrangement ,:

An ink-jet print printer is an ink-jet print printer that prints print data created by print data creation means on a surface to be printed using a water-insoluble ink. The ink jet printer includes a printer main body and a printer controller. The printer controller drives the printer main body based on the input print data to drive the ink jet printer, thereby obtaining a pattern as shown in FIG. The printer and the design data, or, depending on the specifications, only the design data, are printed on the surface to be printed. The ink set in the printer is an alcohol-based solvent dye. The main solvents are methyl alcohol and] 3— It is preferable that the ink has a surface tension that is close to or smaller than the surface tension of the coated surface. If the system is to be used for full color printing, this should be selected. Multiple basic colors and Z or neutral color inks are provided: In the case of a specification in which a cutting line is drawn based on data, for example, drawing can be performed using an ink head provided with an ink that becomes invisible by post-processing. In addition, the design data can be rendered with ink that is visible to the naked eye only with artificial light, for example:

An example of the operation of the above-mentioned on-demand system is shown in the form of a flowchart in Fig. 4. When it starts up, it first determines the shoes of the desired style from among the multiple styles of shoes displayed on the display device. The decision is input from an input device such as a keyboard or a mouse .: Then, in the first stezza, a three-dimensional image selection process for selecting a three-dimensional image corresponding to the selected shoe is performed. The related data of the selected three-dimensional image is read out from the database of the selected style. When the desired style is determined in this way, the desired pattern to be added to the shoes of the determined style is selected, and the next step pattern is selected. The selection process is performed: As a result, the relevant data of the selected pattern data is read out:

Replacement form (Rule 26) When the stereoscopic image and design of the desired shoe are selected in this way, these data are combined in a pre-set relative relationship and displayed on the display means: The displayed hatch is, for example, the gloss shown in Fig. 2. It may be a finished image in which a design is attached to a three-dimensional image expressing the texture or texture, or first display the image developed on a flat surface as shown in Fig. 3 and then display the three-dimensional diagram in Fig. 2 The procedure may be as follows: While confirming the relationship between the two pieces of pasted data displayed on the display device, operate the input device to adjust the positional relationship and determine the desired positional relationship—the positional relationship is determined. The pattern selection process, the relative relationship input process, and the display process are repeated as a subroutine until the desired positional relationship is determined, and then the next printer data creation process is executed. -The above subroutine is automatically and periodically repeated, for example, and the design data is grasped and moved on the screen by the pointing means such as a cursor to determine a relationship (corresponding to a relative relationship input process), and a three-dimensional image is simultaneously confirmed. In this case, the input state that is holding the design data by the force solver will indicate “V)” at the step “Good” in the subroutine. It is also possible to adopt a configuration in which the routine is repeated only when a request is made. That is, the relative arrangement of the pattern data is determined on the display screen of the pattern data by the relationship determining means (corresponding to the relative relationship input processing). Display the determined relationship as a three-dimensional image.

—If you perform a sol operation and are instructed to create a three-dimensional image, etc., it is determined to be "\ ₀ " and you may exit the above subroutine and proceed to the blooming step: In this way, your favorite stereoscopic data and your favorite pattern data Data is created for the top of the shoe, etc. arranged in the desired positional relationship-When the blind data is created, the controller is driven based on these data and set in the printer body Direct printing of the type data and design data on the leather material for the upper, etc. in the determined positional relationship: In the case of specifications that do not include the type data, only the design data is printed directly. Replacement sheet (Rule 26) It is. When the layout data is included, the design data is printed on the printing surface in the layout determined by the layout data.

Fig. 5 shows a table comparing the results of printing on various materials by the method of the present invention (top row of the table) according to the above procedure and the wet rub fastness obtained by other printing methods. It shows that good results have been obtained for natural leather and P-film (material with a polyurethane coating layer formed on it). Pre-treatment and post-treatment are required for sublimation transfer and thermal transfer. However, according to the method and apparatus of the present invention, it is possible to obtain direct prints having almost the same fastness as those without the pre- and post-processing required for sublimation transfer and thermal transfer. Of course, since heat is not applied, it can be said that the printing is more effective in that the printing utilizes the luster and texture of natural material ゃ polyurethane as it is. Although the robustness can be ensured, the present invention does not refuse to add pre-processing and post-processing.

As explained above, each shoe pair produces a fabric with the desired pattern in the desired position in the desired style.In addition to the inkjet flint system, other printing systems using alcohol-based solvent dyes can be used. Inkjet has the advantage of being able to print irrespective of slight irregularities on the surface to be printed-especially with the surface roughness as a natural texture such as leather. In this embodiment, the description has been made mainly of the alcohol-based solvent dye, but this does not limit the use of other water-insoluble inks and departs from the gist of the present invention. The use of other water-insoluble inks may be expected to the extent that they do not:

Furthermore, in the data creation by the blind data creation means, while maintaining the contour, a color gradient represented by a dither process is used to realize a color gradient between the contours. You can also: In this case, replacement paper for different shades or wavelengths (Rule 26) Because of the unevenness, a three-dimensional effect is expressed in the color gradient, which is excellent for printing on materials that are desired to have such natural unevenness such as leather. The flint data can be more aggressively given to the design data portion with a predetermined fluctuation within the range that does not break the design, to further enhance the texture of nature: If the surface is used to add irregularities to the surface, synthetic leather can not only pursue a more natural texture, but also can provide a variety of high-sensitivity expressions.

In the above embodiments, women's shoes have been particularly described as examples, but the present invention is not limited to these embodiments, and it goes without saying that various applications can be made without departing from the gist of the present invention. According be at least shoes Ya鞫and ^1, short delivery time to the cormorant leather field, not only it is possible to small-lot production, excellent dyeing fastness properties, it is possible to do or simplified dispense with post-stroke
