Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing a surface pattern pattern of a dyed dobby dye, and more specifically, in an apparatus for expressing a color by using a computer, a color determined by a name, a color numerical value, and its designation is stored in a computer. (RGB / pixel)
And a color conversion device that expresses the colors (YMCBk) of a color printer, for example, in the fields involved in the production of textiles from yarns, such as textile planning, design, and weaving (hataya). It is suitable.

[0002]

2. Description of the Related Art The procedure for producing a dyed fabric is to determine the yarn (color, thickness, twist), weave design (plain weave, twill weave, satin weave, etc.), yarn arrangement (combination of warp and weft), density ( (Counter, standard density). By combining these, weave (weave) the fabric exactly as the designer intended.
However, since there are a large number of elements and combinations, the impressions and finishes (feeling, color, pattern, etc.) received will differ even if only one of them is different. In particular, the color of the yarn is important in the woven fabric, and even if only the warp and the weft are good, when the fabric becomes a woven fabric, the combination of the warp and the weft gives different feelings and patterns.

For example, there are an infinite number of combinations of yarns (hereinafter referred to as weaving units) composed of a plurality of warp yarns according to the weaving structure, and even if the order of each yarn is changed, a completely different color and pattern can be obtained. And even if you change the number of colors, it will be different. The same applies to wefts, which is the reason why more combinations of warp and weft are created, and designer-specific color designations and combinations are created, and these subtly different shades are the places where originality can be expressed.

However, in order to express colors on a computer, the characteristics of color CRTs and color printers should be well understood, and the designer can specify the density unit, the number of colored threads, and the registered colors. I can't find a system that I can call.

[0005]

[Object] In the present invention, when a dyed fabric is computerized, a fabric pattern image can be displayed on a color CRT and printed by a color printer with the contents desired by a designer. In other words, various combinations and various examinations and comparisons can be performed with almost the same operation, with the purpose of working efficiency, simplification, simplification, and labor saving.
In particular, in the simulation of cloth pattern images, we aimed to simplify the calling, density, and registration of array product numbers.

FIG. 2 shows the flow of the entire system and FIG. 3 shows the flow of simulation. There is. The present invention will be described in detail below using these flowcharts.

Printer Selection (Step 21) Enter the density N (dots / inch) of the color printer to be used.

User color registration (step 22) When a user (person in charge) is changed, when a new color registration is to be performed entirely, or when the initial state is to be collectively set, a new user color is created and registered. , Output a color sample.
Also, the registered name that is no longer needed is canceled and deleted.

Input of thread (step 23) According to the menu of the work screen displayed on the color CRT 4, the type of thread, that is, a single color twisted thread or 2
The control unit 1 using the tablet 8 to determine whether the color is a twisted yarn or the like.
To enter. In the case of a two-color twisted yarn, the twisting direction and the number of twists of the yarn are input by the keyboard 7.

Tissue input (step 24) In accordance with the menu of the work screen displayed on the color CRT 4, information on forward insertion and glass insertion is input to the control unit 1 using the tablet 8 in order to specify the fabric structure. . In the case of forward insertion, enter the basic organization data, and in the case of debris insertion, enter the basic organization and method data.

FIG. 4 is a diagram showing the basic structure of a woven fabric,
The figure (a) shows a plain weave, the figure (b) shows a twill weave, and the figure (c) shows a satin weave. In the figure, black lines are warp yarns (warp yarns) and white lines are weft yarns (weft yarns). Figures (d) to (f) are schematic diagrams in which a part (chain line portion) of the plain weave, twill weave, and satin weave is enlarged, and, for example, in the case of plain weave, as shown in (d), And the weft are alternately arranged to form a basic structure. In Figs. (D) to (f), the portions painted in black indicate that the warp appears on the weft.

Arrangement Input (Step 25) (1) Arrangement Input-Insertion of Warp and Weft 1) According to the menu of the work screen displayed on the color CRT 4, the tablet 8 is provided with information regarding colors in order to perform arrangement input. It is used to input to the control unit 1. Of the items necessary for the arrangement of the warp and the weft, first, specify the density of the warp and the weft in inches or centimeters. 2) Pick "insert" in the warp or weft of the menu of the work screen displayed on the color CRT 4 using the tablet 8. Next, pick the area of the color number you want to insert. 3) When these two operations are performed, the data after the designated line is shifted down by one line and a blank line is inserted. 4) As a result, one color thread can be inserted, and the subsequent color numbers of the warp and weft threads and the number of threads can be input from the keyboard 7. 5) If the color number is registered in the eighth color number of the warp and weft, or if the number of color yarns is registered in that line, the insertion cannot be performed. This is because the loom can handle up to 8 colors at the same time. 6) Similarly, when the number of the color array to be inserted is picked after the "insert" pick, a blank column is inserted at the position of the color number to be specified. If the number of lines is registered in the final data of the color array, it cannot be inserted.

(2) Arrangement Input-Deletion of Warp and Weft 1) Pick "Delete" on the warp or weft of the menu of the work screen displayed on the color CRT 4 using the tablet 8. Then pick the area of the color number you want to delete. 2) When these two operations are performed, one line of data in the specified line is deleted, and the data below it is shifted up by one line. 3) As a result, one color of colored yarn can be deleted. 4) Similarly, if the number of the color array to be deleted is picked after the "delete" pick, the number of the specified color number is deleted, and the data after that is shifted by one.

(3) Array input-longitudinal arrangement copy 1) Pick "Lathe arrangement copy" or "Lateral arrangement copy" in the menu of the work screen displayed on the color CRT 4 by using the tablet 8. The former duplicates the data of the latitude array to the latitude array, and the latter duplicates the data of the latitude array to the latitude array. 2) If you pick "Partial array copy" again,
Partial copy of array data into the same array. In this case, point to the start point of the copy source range, move the pen to point to the end point of the repeat, and then point to the copy destination. 3) The data after the pointed position of the copy destination shifts backward, and the partial copy is completed.

(4) Arrangement input-move to next screen, designation of copy 1) In order to perform arrangement input according to the menu of the work screen displayed on the color CRT 4, the color information is used by using the tablet 8. Input to the control unit 1. The work screen becomes "Arrangement input", and items necessary for arrangement of warp and weft appear. 2) By picking the square of the menu of the work screen displayed on the color CRT 4 using the tablet 8, the contents of the previous one, the contents of the previous 14 color units, the contents of the next one, the contents of the next 14 The content of each color unit can be specified. 3) For a small color array, 14 is enough for the color array, but for a large color array, 100 is not enough.
In such a case, it is used to quickly find the color number of the position you want to specify. 4) Since the positions of the color numbers can be designated independently for the warp and the weft, it is also possible to compare and examine the corresponding parts.

(5) Array input-designation of number of times 1) In "array input", it is possible to designate a plurality of continuous color units as one group and to designate the number of repetitions of the group. 2) In this case, the start point of the repeating group is picked at the intersection of "number of times" and "color number", and the end point is also picked at the intersection. 3) Next, enter the number of repetitions at the start point position from the keyboard. Unless otherwise specified, repeat count 1
Times. 4) In this way, arrays with the same contents can be created without mistakes.

(6) Sequence input-designation of start position 1) When the number of repetitions is designated, the designer is most concerned about which group and how many times to develop the cloth image corresponding to the weave. Therefore, it is important to be able to print a pattern (printing a cloth image) that matches the woven structure from an arbitrary position. 2) Specify the "start" area of the group you want to expand. 3) Next, specify the number of times with the keyboard. 4) As a result, the cloth image corresponding to the woven structure is printed from the specified number of times in the specified group.

(7) Sequence input-designation of registration 1) In the sequence input, the color sequence of the prepared warp and weft yarns can be registered in the system by picking "Register", and used without sequence input in the subsequent use. be able to. 2) By being able to register this, the know-how of the designer can be easily accumulated, and the same thing can be reproduced when necessary.

(8) Arrangement Input-Designation of Calling 1) In the arrangement input, by picking "call" the array of registered warp and weft colors can be taken out from the system. 2) In combination with registration, arbitrary data can be taken out, similar items can be registered after correction, and know-how can be accumulated smoothly.

(9) Array input-designation of new creation 1) In the array input, by picking "New creation", the entire screen can be cleared to the initial state. 2) It can be used for canceling data input mistakes and creating new data.

Simulation (Color Processing) (Step 26) FIG. 5 shows, for example, a warp yarn A of interest in a plain weave fabric design.
5 and the surrounding warp yarns A1, A3, A7, A9 and weft yarn A
FIG. 2 is a surface view of a woven fabric structure composed of 2, A4, A6 and A8. The division processing unit 13 uses the expressible dot number d, the dither z used, and the number of repetitions k obtained by the yarn expression calculation unit 12 to calculate the warp yarn, for example, A5 (referred to as a region) n (longitudinal) ×
It is divided into m (horizontal) small areas aij (the number of dots in the horizontal direction is m), and each small area is 1 in the color printer.
Configure to correspond to dots. Other warps and wefts are similarly divided into a matrix.

For each of the above-mentioned areas, the muzzle yarn expression generating section 14 determines the color to be composed and the twisting direction (right or left).
And the fuzz thread expression data is generated based on the number of twists.
The color of the small area a ₁₁ of the area A5 may be determined according to an algorithm in consideration of the colors of A1, A2 and A4. The color mask processing for extracting each color from the expression data of the fuzz thread created as described above is performed on the control unit 1. 1
The color data and coordinate values of the lines (M warps or N wefts) are passed to the print controller 5.

Since the color display method on the color CRT 4 and the hard copy by the color printer 6 are different in color representation method (RGB signal for color CRT, YMCBk for color printer), color display on the color CRT 4 in advance. Is set to a hard copy by the color printer 6, and the RGB signals are output after being converted into a dither pattern or the like capable of expressing halftone. By doing so, the color of which the design is determined on the color CRT 4 and the color of the hard copy by the color printer 6 which is a sample of the fabric can be matched.

The simulation will be described below with reference to FIG.
