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)

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.

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 with the tablet 8, the previous content and the next content can be designated respectively. 3) It is used to quickly find the color number of the position to be designated when the number of color arrays is large. 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.

As described above, in step 25, in order to input the arrangement according to the menu on the work surface displayed on the color CRT 4, the color information is input to the control section. First, specify the "density" of warp and weft among the items necessary for the arrangement of warp and weft, and then "insert", "delete", "copy warp" and "copy weft" of warp and weft. , "Next screen move", "Repeat count", "Cloth image start position designation", "New creation", "Registration", "Call designation" etc. It becomes each work screen, and you can specify the necessary items.

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 representation method on the color CRT 4 is different from that on the hard copy by the color printer 6 (color CRT is RGB signal, color printer is YMCBk), color display is previously performed on the color CRT 4. 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.
