Description
Technical Field
The invention relates to a trademark weaving method, in particular to a fabric label weaving method.
Background
Most of the existing one-dimensional codes and two-dimensional codes of the trademark and the label are applied to the garment fabric in a printing mode, however, the garment fabric is generally repeatedly washed or washed by adopting a detergent, the two-dimensional codes on the garment fabric are damaged once the service time is long, and difficulty is brought to identifying various important information. In order to solve the problem that the two-dimensional code is easy to damage, some manufacturers try to show the one-dimensional code and the two-dimensional code on the garment fabric in a weaving mode, but cannot succeed, and the following reasons are:
1. the printing mode is the same in unit length in both the transverse and longitudinal directions, but in the trademark weaving field, because the warp yarn density and the weft yarn density are not equal. Therefore, a square pattern is woven out to generate deformation, so that the woven two-dimensional code cannot be identified.
2. The lattice arrangement of the two-dimensional patterns does not completely meet the requirement of trademark weaving, and the trademark weaving requires that warp yarns and weft yarns are mutually hooked and interwoven, and the two-dimensional patterns in the plane printing can cause the conditions of yarn shedding, cloth cover loosening or fabric bottom exposure and the like if no special treatment is carried out.
Aiming at the problems, the current solution is to generate a two-dimensional code, select a proper weaving mode according to the specific condition of a two-dimensional code pattern, and calculate the corresponding warp yarn density and weft yarn density when the two-dimensional code pattern can be identified. Therefore, the woven two-dimensional code can be identified, but the two-dimensional code woven by one weaving machine is identical. If the same weaving machine is required to weave different two-dimension codes, warp and weft yarns with different densities or weaving modes need to be replaced, so that the machine is troublesome and low in efficiency. Also, because of this, the current weaving machine cannot notify to weave a plurality of different two-dimensional codes, i.e. one mark-by-one code, on the same layout.
That is, current weaving machines do not achieve the inclusion of multiple different labels in the same layout being woven.

Detailed Description
Example 1
The invention discloses a weaving method of a fabric label, which comprises the following steps:
step 1, generating a plurality of different label patterns, wherein each label pattern at least comprises a variation area, and the variation area is an area where the pattern is changed.
The label pattern may further include a fixed area, which refers to an area where the pattern is not changed. The pattern of the fixed area is the same and the pattern of the variable area is different between two different label patterns.
In general, the customer will provide an order, and the label pattern is generated based on the order. Specifically, the order requirements include a tag sample (as shown in fig. 1) and a sequence range, the tag sample including a variable region and a fixed region, the pattern of the variable region being associated with the sequence number. And generating a variable region pattern according to the serial numbers in the sequence range, and combining the variable region pattern with the fixed region according to typesetting of the label sample to generate a complete label pattern.
The label pattern can be one or a combination of a plurality of characters, graphics, trademarks, one-dimensional codes, two-dimensional codes, serial numbers and the like. In general, the pattern and trademark are patterns of a fixed area, and the one-dimensional code, the two-dimensional code and the serial number are patterns of a variable area, and the characters can be used as the patterns of the fixed area or the patterns of the variable area.
The one-dimensional code is generated by a one-dimensional code generating module of the system according to the serial number. The Code system of the one-dimensional Code comprises EAN, UPC, coder Bar, code39, code128 and the like. The two-dimensional code is generated by a two-dimensional code generation module of the system according to the serial number. The two-dimensional code system comprises code systems of QR, dataMatrix, PDF417, maxiCode, code, codeOne, chinese message code and other different technical specifications.
And step 2, obtaining production parameters of the woven label, and rewriting a bitmap file structure of the label pattern according to the production parameters to realize bitmap lattice transformation. The production parameters of woven label include warp yarn density, weft yarn density and effective weaving width.
The bitmap file is composed of four parts:
1. bitmap file header (bitmap-fileheader);
2. bitmap information header (bitmap-information header);
3. color table (color);
4. color dot matrix data (bitsdata).
And (3) rewriting data in the bitmap file structure according to the warp yarn density and the weft yarn density, so that the bitmap lattice transformation is realized, and the bitmap meets the requirements of trademark woven labels.
Specifically, assuming that the width and height of the sample mark are width (millimeters) and height (millimeters), respectively, the warp yarn density and weft yarn density are jm (number of yarns/millimeter) and wm (number of yarns/millimeter), respectively, the calculation formulas of the width W and the height H of the rewritten label bitmap are as follows:
if it is a cross weave, then: w=width jm; h=height×wm.
If it is a vertical weave, then: w=width; h=height.
And 3, carrying out optimization processing on the bitmap after the bitmap is subjected to the lattice transformation.
The bitmap after lattice transformation often has the problems of distortion, saw tooth and the like, and still cannot be applied to trademark woven labels, and further image optimization is needed.
Specifically, firstly, the bitmap after the lattice transformation is sampled, and whether an optimized point exists or not is judged, wherein the optimized point is an interweaved point which exists only in two weaving blocks, such as a point A, a point B, a point C, a point D and a point F shown in fig. 2.
Then, when there is an optimization point, the optimization point and points around it are optimized.
And then, continuously sampling the optimized bitmap, judging whether the bitmap has an optimization point again, if so, continuously optimizing, otherwise, indicating that the optimization is completed. The pattern after the optimization is shown in fig. 3.
In this embodiment, the optimization method is bilinear interpolation or bicubic interpolation. The bilinear interpolation method takes 4 sampling points around the target pixel point to carry out weighted average to obtain the value of the target pixel point.
As shown in fig. 4, assuming that the pixel coordinates to be interpolated are (X.x, Y.y), uppercase and lowercase represent the integer and fractional parts of the coordinates, respectively, and f (X, Y) is a function of the read pixel value. Then the result of bilinear interpolation is
f(X.x,Y.y)＝(1-x)f(X,Y)+xf(X+1,Y)+[(1-x)f(X,Y+1)+xf(X+1,Y+1)]y＝(1-x)(1-y)f(X,Y)+x(1-y)f(X+1,Y)+(1-x)yf(X,Y+1)+xyf(X+1,Y+1)
If the effect of bilinear interpolation is still not ideal, the bicubic interpolation is adopted to optimize, more than bilinear sampling points are adopted, and the weighted average of 16 sampling points around the target pixel point is taken to obtain the target pixel value. As a result of bicubic interpolation, as shown in connection with fig. 5,
F(i+v，j+u)＝A*B*C
A＝(S(1+v) S(v) S(1-v) S(2-v))
where i, j is the integer part of the coordinates. v, u is the fractional part of the coordinate. f (i, j) is a function of the read pixel. S (x) is a weight function.
The weight function S (x) may also be represented by W (x), as follows
Wherein the value of a is described as follows:
-0.5 cubic Hermite spline;
-a common value of 0.75;
-1 approximates y=sin (x PI)/(x PI);
-2 usual values.
And 4, typesetting all the optimized label bitmaps according to the effective weaving width, and then converting the typeset label bitmaps into a woven label manufactured layout.
And 5, guiding the woven label manufacturing layout into a weaving machine to weave the fabric labels.
Example two
The present embodiment is basically the same as the first embodiment in concept, except that the first embodiment performs the processing of step 2 and step 3 for each generated tag pattern, so that the pattern processing speed is slow.
Since the fixing areas of different tag patterns are the same and do not change, the fixing areas are only required to be processed at first, and then the fixing areas of the tag patterns of each tag are required to be used at all, so that the processing is not required to be repeated. Therefore, when the tag pattern includes a fixed area and a variable area, the method of the present embodiment includes the steps of:
step 1, acquiring an order requirement, wherein the order requirement comprises a label sample and a sequence range, and the label sample comprises a fixed area and a variable area.
Step 2, obtaining a fixed area pattern in the label sample, and performing the following processing:
dot matrix transformation is carried out on the pattern bitmap of the fixed area according to the production parameters of the woven label; and carrying out optimization treatment on the bitmap after the point array transformation to obtain an optimized fixed area bitmap.
Step 3, generating a plurality of variable region patterns according to the serial numbers in the sequence range, and carrying out the following processing on each variable region pattern:
dot matrix transformation is carried out on the pattern bitmap of the fixed area according to the production parameters of the woven label; and carrying out optimization treatment on the bitmap after the point array transformation to obtain an optimized variable area bitmap.
The lattice transformation and optimization in step 2 and step 3 are the same as those in the implementation, and will not be described here again.
And 4, combining each variable region bitmap and the fixed region bitmap according to the format of the label sample to form a plurality of complete label bitmaps.
And 5, typesetting all the optimized label bitmaps according to the effective weaving width, and then converting the typeset label bitmaps into a woven label manufactured layout.
And 6, guiding the woven label manufacturing layout into a weaving machine to weave the fabric labels.
In this embodiment, if only the variable region is provided in the label sample, the step 2 may be omitted.
As shown in fig. 3, if the order request provided by the customer is in the sequence range: the label sample comprises a fixed area and a variable area, wherein the fixed area consists of a trademark and characters (spirit identification), and the variable area consists of a two-dimensional code and a serial number, and the two-dimensional code varies along with the variation of the serial number.
If the method according to the first embodiment is adopted, variable regions of 1001 pattern labels are generated according to the sequence range VC1234567G-VC1235567G, and then each variable region is spliced with a fixed region in the label sample to form a finished label pattern. And performing lattice transformation and optimization on all the tag patterns, typesetting all the processed tag patterns, converting the typeset tag patterns into woven mark manufactured patterns, and finally guiding the woven mark manufactured patterns into a weaving machine for weaving.
If the method is according to the second embodiment, a fixed area of the label sample is obtained, and lattice transformation and optimization are carried out on the fixed area; then generating 1001 a variable region according to a sequence range VC1234567G-VC1235567G, and performing lattice transformation and optimization treatment on each variable region; splicing each optimized variable area and fixed area together according to the format of the label sample to form 1001 label patterns; typesetting all the tag patterns, converting the typeset tag patterns into woven mark manufactured patterns, and finally, guiding the woven mark manufactured patterns into a weaving machine for weaving.
In summary, the invention performs lattice transformation and optimization treatment on the label patterns according to the woven label parameters of the weaving machine, and all the label patterns after treatment meet the trademark weaving requirement and are also suitable for the weaving machine, so that the label woven by the invention can not deform and can be accurately identified, and a plurality of different label patterns (namely one label for one picture) can be manufactured on the same layout.
The foregoing embodiments of the present invention are not intended to limit the technical scope of the present invention, and therefore, any minor modifications, equivalent variations and modifications made to the above embodiments according to the technical principles of the present invention still fall within the scope of the technical proposal of the present invention.
