Background technology
Cross embroidery (crossstitch), be special embroidery line on base cloth, the method for taking cross utilizing longitude and latitude to interweave, contrast special coordinate pattern and embroider, anyone can embroider out a kind of embroidering method of effect same.
For the ease of trying to make a match, Ji Bushang is densely covered with every spininess hole, and four adjacent pin holes form a grid, but the pattern of early stage cross embroidery or grid print with the ink that can wash or draw, after manually embroidering cross-stitch line, wash away and originally wash ink, form cross embroidery finished product.This cross embroidery needs at substantial artificial, and finished product cannot be produced in batches, is unfavorable for the development of cross embroidery industry.
For this reason, people have invented stereo cross embroidery, the base cloth that stereo cross is embroidered only reserves a part of region (this region can be printed cross embroidery color lump pattern or represent symbol or the numeral of different color blocks) and embroiders cross embroidery for people, remainder is by printing refining background patterns with the ink that can not wash, do not need to embroider again, such one side decreases manually, and finished product has stereoeffect on the other hand.
But base cloth always there will be oblique weft, all inevitably go out inclined lattice phenomenon when printing, once there are inclined lattice, cross embroidery base cloth just cannot employ.For this reason, people have installed multiple camera on the accurate printer of cross embroidery base cloth, are gathered base cloth image by camera, and base cloth image input printer is controlled computer, control computer carry out accurate grid positioning printing by printer.But this mode utilizing camera collection base cloth image, still cannot stop the appearance of inclined lattice phenomenon.
No matter be cross embroidery inkjet color printing machine or normal inkjet color printer, all undertaken printing by the printhead on black car, printhead is connected with red, yellow, blue, black four look print cartridges respectively, during color printer work, under the control controlling computer, each point needs red, yellow, blue, black four chromatic inks spraying different amount, thus forming shades of colour and pattern, each point needs the threshold value of a coordinate parameters and four red, yellow, blue, black four chromatic ink consumptions (being collectively referred to as four chromatic threshold values) to define.
Summary of the invention
The technical problem to be solved in the present invention is the above-mentioned defect how overcoming prior art, provides a kind of accurate control method of cross embroidery printer and corresponding environmental protection clear water cross embroidery.
For solving the problems of the technologies described above, the accurate control method of cross embroidery printer of the present invention comprises the steps:

3.. gather base cloth image: base cloth image collecting device is set in spray car upstream, utilizes this base cloth image acquisition device base cloth image, and provide the coordinate of each pin hole on base cloth, be transferred to control computer;
4.. the former figure of amendment design: by controlling computer, design former figure in cross embroidery and find out the point corresponding with each pin hole coordinate, often adjacent four points are a print unit, find out the immediate embroidery line with each print unit color respectively, with four chromatic threshold values of this immediate embroidery line, as four chromatic threshold values of all ink dots of corresponding print unit, and immediate embroidery line is embroidered line as the adapted of this print unit;
5.. print: by controlling computer, by corrections afterwards cross embroidery design drawing print on corresponding base cloth layer, and to guarantee in the region between corresponding four pin holes that each print unit all prints to base cloth.
Design like this, use the technology of the present invention, any image can directly input cross embroidery printer as the former figure of cross embroidery, prints cross-stitch cloth, and printing precisely, makes utilization embroider line symbol and replaces embroidery line color lump to become possibility.
As optimization, described base cloth image collecting device is row's scan module, and this scan module is arranged on below base cloth.Design like this, on the one hand scan module is arranged under Ji Bu, and near stamp pad, capture is accurate, thus ensures precise Printing, has stopped because inclined lattice cause the generation of cross embroidery base cloth subscription rate phenomenon.The preferred precision of scan module is equal to or greater than the scan module of 7200dpi, the preferred high-precision printhead of printing head.
As optimization, 4. the when walking the former figure of amendment design, according to four chromatic threshold values of ink dot each in print unit---red, yellow, blue, blackly carry out statistic of classification, find out four chromatic threshold values of the maximum ink dot of quantity in same print unit, and respectively embroider four chromatic threshold values of line as comparison by this four chromatic thresholds value and embroidery line storehouse, find out four chromatic threshold values of immediate embroidery line, as four chromatic threshold values of all ink dots of this print unit, and immediate embroidery line is embroidered line as the adapted of this print unit.In same print unit, minority ink dot will obey most ink dot in embroidery line options.
Be all with artificial during Earlier designs cross embroidery, according to the color needs of each print unit, selection embroidery line, very complicated, wastes time and energy, and accuracy is not high.
Design like this, four chromatic threshold values are compared, select embroider line time, by control computer, to be compared selection by control computer according to red, yellow, blue, black, namely be first as the criterion with red threshold, select the immediate embroidery line of color, have the red threshold of multiple embroidery line and corresponding print unit red threshold closest to time, comparison yellow threshold value, is as the criterion with yellow threshold value again, selects the immediate embroidery line of color, next coming in order are analogized, comparison blue thresholds, black threshold respectively, until select closest to embroidering line, forms design sketch.And then by black, red, yellow, blue or other orders, comparison threshold value, selects to embroider line, finally forms multi-effect figure, select for operator.
As optimization, 4. the when walking the former figure of amendment design, to four chromatic threshold values of ink dot each in print unit---red, yellow, blue, blackly carry out statistic of classification, ask for four chromatic threshold values---red, yellow, blue, the black average of all ink dots, obtain average four chromatic threshold values, and respectively embroider four chromatic threshold values of line as comparison by these average four chromatic threshold values and embroidery line storehouse, find out four chromatic threshold values of immediate embroidery line, as four chromatic threshold values of all ink dots of this print unit, and immediate embroidery line is embroidered line as the adapted of this print unit.
Design like this, compares to four chromatic threshold values, when selecting to embroider line, also can select by controlling computer-aided according to aforementioned principle.
As optimization, the when 5. step prints, and the color lump first representative of all or part of print unit difference being embroidered line replaces with the symbol representing corresponding embroidery line, and then in region between corresponding four pin holes color lump or symbol being printed to base cloth.
Substitute mode one is as follows: first by four chromatic threshold value zeros of ink dots all in print unit, then on this print unit, finding out the coordinate of the ink dot that can form the symbol representing corresponding color lump by controlling computer, changing positive into by one or more for four chromatic threshold values of these ink dots.Design like this, equals first primary colors block delete, and then adds respective symbol, and the Color tunable of symbol.
Substitute mode two is as follows: the coordinate finding out the ink dot that can form the symbol representing corresponding color lump by controlling computer on this print unit, by four chromatic threshold value zeros of all the other all ink dots in print unit.Design like this, equals to wipe redundance in color lump on print unit, forms respective symbol.
As optimization, by substitute mode one, the color lump that the representative of print unit difference embroiders line is replaced with the symbol representing corresponding embroidery line, and carry out integration respectively by controlling the four chromatic threshold values of computer to the ink dot of all previous printing, obtain red, yellow, blue, the accumulative printing amount of black four chromatic inks, with red, yellow, blue, the expection printing amount of black four chromatic inks deducts red respectively, yellow, blue, the accumulative printing amount of black four chromatic inks, find out the ink that residue printing amount is maximum, as maximum surplus ink, then can form in four chromatic threshold values of the ink dot of the symbol representing corresponding embroidery line and change positive into the threshold value of maximum surplus ink same color.
Design like this, can balance with ink, play the potentiality of printhead to greatest extent, extends print head longevity.
