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 of a dyed dobby dye, and more particularly, to an apparatus for expressing a color using a computer. (RGB / pixel)
And a color conversion device expressed by the color of a color printer (YMCBk), for example, used in fields such as planning of textiles, design, and weaving (hataya), which are involved in producing textiles from yarn. It is suitable.

[0002]

2. Description of the Related Art Procedures for producing a yarn-dyed fabric include determination of yarn (color, thickness, twist), weave structure (plain weave, twill weave, satin weave, etc.), arrangement of yarn (combination of warp and weft), density ( Number, standard density). By these combinations, weaving (weaving) the fabric as intended by the designer
However, since the number of each element and the number of combinations are numerous, even if any one is different, the impression received and the finished condition (feel, color, pattern, etc.) are different. Especially in the case of woven fabrics, the color of the yarn is important. Even if only the warp and the weft are sufficient, when the woven fabric is woven, the combination of the warp and the weft gives a different feeling and pattern.

[0003] For example, there are countless combinations of yarns (hereinafter referred to as weaving units) consisting of a plurality of yarns according to the weave structure, and even if the order of each yarn is changed, the yarns have completely different colors and patterns. In other words, just changing the number of colors is a different thing. The same is true for weft yarns, and the number of combinations of warp and weft yarns further increases, and this is why designers' unique color designations and combinations are born, and these slightly different colors are places where originality can be expressed.

However, in order to express colors using a computer, the characteristics of color CRTs and color printers must be well understood, the specification of the density unit normally used by the designer, the specification of the number of color yarns, and any registered colors can be used. There is no system that can be used to call this.

[0005]

[Object] In this invention, when computerizing a surface pattern pattern of a dyed dobby fabric, a cloth pattern image is displayed on a color CRT and printed by a color printer.
It was possible with the contents that the designer wanted. In other words, various combinations, various examination comparisons, and the like can be performed by almost the same operation, and the purpose is to achieve work efficiency, simplification, simplification, and labor saving. In particular, in the simulation of a cloth pattern image, calling of cloth pattern data, search registration,
The purpose was to simplify the printing (printer).

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

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

Input of thread (step 23) In accordance with the menu on 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 determines whether or not the yarn is a color twist using the tablet 8.
To enter. In the case of a two-color twisted yarn, the twist direction and the number of twists of the yarn are input by the keyboard 7.

Tissue input (step 24) In accordance with the menu on the work screen displayed on the color CRT 4, in order to designate a woven fabric, information on ordering and lashing is input to the control unit 1 using the tablet 8. . In the case of sequential insertion, the basic organization data is input, and in the case of the insertion, the basic organization and the insertion data are input.

FIG. 4 is a diagram showing the basic structure of the woven fabric.
(A) shows a plain weave, (b) shows a twill weave, and (c) shows a satin weave. The black line in the figure is the warp (warp), and the white line is the weft (weft). Figures (d) to (f) are organization diagrams in which a part (dashed line portion) of the plain weave, twill weave, and satin weave fabric structures are enlarged. For example, in the case of plain weave, the warp yarns are shown in FIG. And the weft are arranged in units of a basic structure in which they are alternately arranged. In the figures (d) to (f), the portions painted black indicate that the warp appears on the weft.

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 data below it is shifted up by one line. 3) As a result, one color of the color thread 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 designated color number is deleted, and the data thereafter is shifted by one.

(3) Sequence Input-Latitude (Latitude) Sequence Copy 1) When "Latitude Sequence Copy" or "Layer Sequence Copy" of the menu on the work screen displayed on the color CRT 4 is picked using the tablet 8, In the former, the data of the latitude array is copied exactly to the longitude array, and in the latter, the data of the longitude array is copied completely to the latitude array. 2) If you pick “Copy partial sequence” again,
Partial copy of the sequence data into the same sequence. In this case, point the start point of the range of the copy source, move the pen to point the end point of the repetition, and then point the copy destination. 3) Data after the pointed position of the copy destination is shifted backward, and the partial copy is completed.

(4) Arrangement Input-Movement to the Next Screen, Designation of Copying 1) In order to perform arrangement input in accordance with the menu on the work screen displayed on the color CRT 4, color information is input using the tablet 8. Input to the control unit 1. The work screen becomes "array input", and items necessary for the arrangement of warp and weft appear. 2) By picking a square on the menu of the displayed work screen on the color CRT 4 using the tablet 8, the previous content and the next content can be respectively specified. 3) When the number of color arrays is large, it is used to quickly find a color number at a position to be designated. 4) Since the position of the color number can be designated independently for the warp and the weft, it is also possible to compare and examine the corresponding portions.

(5) Arrangement Input-Specification of Number 1) In "arrangement input", a plurality of continuous color units are regarded as one group, and the number of repetitions of the group can be designated. 2) In this case, the start point of the repetition group is picked at the intersection of “number of times” and “color number”, and the end point is similarly picked at the intersection. 3) Next, the number of repetitions is input from the keyboard to the position of the starting point. Unless otherwise specified, repeat count 1
Times. 4) Thus, an array having the same contents can be created without errors.

(6) Array Input-Specification of Start Position 1) When the number of repetitions is specified, the designer uses the most nerves to determine which group and from which time the cloth image is developed corresponding to the woven tissue. For this reason, it is important to be able to print a pattern (printing a cloth image) that matches the woven structure from any position. 2) Specify the "start" area of the group you want to expand. 3) Next, specify the number of times from the keyboard. 4) As a result, the cloth image corresponding to the woven tissue is printed from the specified number of times of the specified group.

(7) Sequence input-designation of registration 1) In sequence input, the registered color array of the warp and weft can be registered in the system by picking "registration". be able to. 2) By being able to make this registration, the know-how of the designer can be easily accumulated, and the same thing can be reproduced when necessary.

(8) Array input-designation of call 1) In the array input, the registered color array of warp and weft can be taken out of the system by picking "call". 2) In combination with registration, arbitrary data can be extracted, similar data can be registered after correction, and know-how can be accumulated smoothly.

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

6) FIG. 5 shows, for example, a warp A of interest in a plain weave fabric structure.
5 and its surrounding warp A1, A3, A7, A9 and weft A
FIG. 4 is a surface view of a woven fabric composed of 2, A4, A6, and A8. The division processing unit 13 uses the expressible number of dots d, the used dither z, and the number of repetitions k obtained by the yarn expression calculation unit 12 to convert this warp, for example, A5 (referred to as an area) into n (vertical) ×
It is divided into m (horizontal) small areas aij (the number of dots is m in the horizontal direction), and each small area is
It is configured to correspond to a dot. Other warps and wefts are similarly divided into a matrix.

For each of the above-mentioned regions, the knitting yarn expression generation unit 14 determines the color to be composed and the twist direction (right or left).
Then, based on the number of twists, the yarn representation data is generated.
The color of the small region a ₁₁ of the region A5 may be as determined in accordance with an algorithm that takes into account the color of the A1, A2, A4. The color mask processing for extracting each color from the expression data of the yarn created as described above is performed on the control unit 1. 1
The color data and coordinate values of the lines (M warp yarns or N weft yarns) are passed to the print controller 5.

Since the color expression method is different between the color display on the color CRT 4 and the hard copy by the color printer 6 (RGB signals for the color CRT and YMCBk for the color printer), the color display on the color CRT 4 is performed in advance. And a hard copy by the color printer 6 are set, and, for example, an RGB signal is converted into a dither pattern or the like capable of expressing halftones and then output. In this manner, the color determined on the color CRT 4 and the color of the hard copy by the color printer 6 as a sample of the fabric can be matched.
