The method of digital image designing emulating fabric
Technical field
The present invention relates to a kind of method for designing of graticule MIXED FABRIC, particularly the jacquard fabric method for designing of fabric effect imitation digital image effect.
Background technology
The design of the textile simulating of pattern need realize by the fabric construction that design has a simulated effect, and adopt the mode of production of jacquard weave to come the weaving fabric, traditional textile simulating design is to adopt manual mode to finish, after using the jacquard fabric computer aided design system, begin to adopt the method for designing of color separation combination, but because the colour developing principle of MIXED FABRIC has the advantages that non-overlay space mixes, mixing colour developing and computer color principle with pigment there are differences, the color that will duplicate hand drawing pattern or computer picture fully is very difficult, can only carry out emulation in a way, when the difference on the textile simulating method for designing has determined that pattern effect is converted into fabric construction to the emulation degree of former figure.Deficiency aspect there are two in the emulating fabric that designs production in current employing craft or CAD mode: the one, color error ratio is serious, and the 2nd, the fabric construction instability causes the fabric colour developing uncertain.
The emulating fabric method for designing of current employing is that pattern is scanned into computer, specifies some representative colors to carry out design textile structure after the color separation according to pattern characteristic, adopts the look silk of same hue to go back original production during production.Because the principle of computer color color separation and combination colour developing and the non-stack color mixture principle of MIXED FABRIC there are differences, deviation is serious especially to make emulating fabric design the reduction effect that has produced gray scales such as serious color error ratio, particularly black on color is handled.
The current disclosed technology that can be used for the emulating fabric structural design, it mainly is the shadow weave method for designing that adopts rule to change, because shadow weave is after combination, can't avoid taking place the effect of covering mutually between tissue between the interlacing point, make the mixed color of fabric be in uncertain state, can not be consistent with the non-stack color mixture principle of fabric, cause between fabric color and the designing requirement to exist than large deviation.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, innovate by key technique Fabric Design, remedy the difference between computer colour developing principle and the MIXED FABRIC colour developing principle, the emulating fabric structure chart of design is chromatic colour shadow light effect both, can satisfy the specification requirement that shadow weave combination back interlacing point does not hide mutually again, reach the purpose that reduces fabric colour cast and stable fabric structure
The present invention is achieved through the following technical solutions: (1) adopts twice CMYK primary colors color seperation, substitute numerical value by regulating gray scale, obtain the blue or green Cyan (hereinafter to be referred as C) of digital image respectively, pinkish red Magenta (hereinafter to be referred as M), yellow Yellow (hereinafter to be referred as Y) and four branch chromatic graphs of black Black (hereinafter to be referred as K) layer, (2) design is satisfied the full colour developing basic organization of non-covering requirement and is cooperated tissue, (3) replacement of digital image gray scale and tissue, be combined to form the emulating fabric structure chart of full color developing effect, Fig. 1 illustrates design cycle, the C that obtains of twice color separation wherein, M, Y, K schemes layer, and the gray scale composition is overlapping can't to have reduced original digital image effect owing to exist.
1. implementation step that each technical scheme is concrete and method are:
(1) color separation of digital image secondary obtains C, M, Y, K scheme layer,
Replace numerical value by setting different gray scales, computer picture is carried out the color separation of twice CMYK primary colors, obtain C, M, Y figure layer and K figure layer respectively, Fig. 2 illustrates the color separation method flow process, Fig. 3 illustrates the gray scale principle of substitution, according to the computer color principle, as C, the M of color composition, when Y numerical value is identical, the stack color representation is the gray scale of netrual colour, this part gray scale can be replaced by the K numerical value of equivalent, the decrement that is C, M, Y numerical value is identical with the increment of K numerical value, can not influence the color output effect, but can reduce the stack colo(u)r specification of color same color dot of when output.Because nontransparent spacing color mixed method is adopted in fabric colour developing, be to reduce colour cast to take place, the deficiency that can come compensating color saturability by the method that increases colo(u)r specification, this just need be provided with different gray scale replacement numerical value, adopts twice color separation to realize, and concrete grammar is:
1. color separation is for the first time set the grey substitution value between 0-50%, and obtain C, M, Y and scheme layer,
2. color separation is for the second time set the grey substitution value between 50-100%, obtains K figure layer,
3. transfer C, M, Y, the K figure layer that obtains to gray level image pattern,
Digital image is by setting different gray scale substitution value, the C that twice color separation obtained, M, Y and K figure layer exist the gray scale composition to intersect, can guarantee under the prerequisite of color effect, gray scale composition to image is regulated, and dwindles the stack colour developing principle of computer and mixes the difference that develops the color between the principle with the non-overlay space of fabric.
(2) develop the color full basic organization and cooperate the design of tissue,
Because the silk thread of fabric is an opaque state, the covering between silk thread all can directly have influence on the mixed effect of fabric color in the same way, and the combination tissue's structure that designs non-covering effect is most important for emulating fabric.This step is to realize the method for designing of organizing of the non-covering effect of four cocainine lines in the same way, according to different designing requirements, can select be used for the developing the color full design of institutional framework of the twill of different tissues circulation or satin weave basic stitch, warp, the circulation of latitude tissue are all N mutually, N is an even number, Fig. 4 illustrates design cycle, and the specific design method is:
1. select two A of elementary organization and B, it is identical that A and B organize, but have different starting points,
2. according to the tissue signature of B, A is set full developing technology point (a kind of tissue), method is the interlacing point counter-rotating with B, and strengthens 1 to the upper edge warp-wise, and one group of shadow weave of design is referred to as basic organization under the situation of not destroying full developing technology point,
The computing formula of organizing number in the basic organization is (N-2)+(N-3) * (N/M-1),
When M=N, basic organization organize the number minimum, for (N-2) individual,
When M=2, basic organization organize the number maximum, for (N-2)+(N-3) * (N/2-1) individual,
N represents to organize period, and M strengthens number for the shadow weave interlacing point, and M is even number and is the approximate number of N,
Tissue in the basic organization is decomposed into two groups of basic organizations by broadwise at 1: 1, and the odd number latitude forms basic organization Aa, and the even numbers latitude forms basic organization Ab;
3. according to the tissue signature of A, B is set full developing technology point (a kind of tissue), method is the interlacing point counter-rotating with A, and strengthens 1 to the lower edge warp-wise, and one group of shadow weave of design under the situation of not destroying full developing technology point is referred to as to cooperate tissue,
Cooperating the computing formula of organizing number in the tissue is (N-2)+(N-3) * (N/M-1),
When M=N, what cooperate tissue organizes the number minimum, for (N-2) individual,
When M=2, what cooperate tissue organizes the number maximum, for (N-2)+(N-3) * (N/2-1) individual,
N represents to organize period, and M strengthens number for the shadow weave interlacing point, and M is even number and is the approximate number of N,
Set up jointly and knit cooperating tissue in the tissue to be decomposed into two assembly at 1: 1 by broadwise, the odd number latitude forms to cooperate organizes Ba, and the even numbers latitude forms cooperation and organizes Bb;
Because at basic organization with cooperate in the tissue and be provided with full developing technology point, as long as combined method meets the requirements, basic organization with cooperates tissue in tissue between can arrange in pairs or groups arbitrarily, can both satisfy the specification requirement that non-covering develops the color entirely.
(3) replacement of digital image gray scale and tissue, the combination back forms the emulating fabric structure chart of full color developing effect,
Grey level number in adjustment C, M, each gray level image of Y, K is less than or equal to the number of organizing in basic organization or the cooperation tissue, maximum filling face tissue and maximum black (the brightness minimum) and white (brightness maximum) in the corresponding computer grayscale mode of covering weave difference among Ba, the Bb organized in setting basic organization Aa, Ab and cooperation, and remain unchanged, brightness value according to different gray scales in the gray level image, carry out the gray scale in C, M, Y, the K gray level image and the replacement of tissue, combination then, Fig. 5 illustrates method for designing and flow process, and concrete grammar is:
