step 301, calculating the total number of the pixel points of the jet printing data and the pixel points of each row of data, and calculating the total number of the pixel points to be extracted according to the current required jet printing concentration and the total number of the pixel points of the jet printing data.
It should be noted that the total number of the pixel points to be extracted is calculated according to the following formula:
DelDot＝Dot*(100-N)/100，
and the Dot is the total number of the pixel points of the jet printing data, N is the current required jet printing concentration, and the Deldot is the total number of the pixel points required to be extracted.
As one example, the current desired jet density may be preset.
And step 302, calculating the pixel number required to be extracted in each row of data according to the pixel number of each row of data, the total pixel number of the jet printing data and the total pixel number required to be extracted.
It should be noted that the number of pixel points to be extracted for each row of data is calculated according to the following formula:
DelDoti＝TolDoti*DelDot/Dot-TolDelDoti-1，
wherein, TolDotiTolDeldot to accumulate the number of pixels from the first line to the ith linei-1For already extracted number of pixel points, DeldotiAnd the Dot number of the pixel to be extracted for each row of data is the total number of the pixel points of the jet printing data, and the Deldot is the total number of the pixel points to be extracted.
That is, the number of pixels to be extracted for the first row of data is:
DelDot1＝TolDot1*DelDot/Dot-TolDelDot0wherein TolDot1＝Dot1，TolDelDot0＝0；Dot1And the total number of the pixel points of the first line of jet printing data.
The number of pixel points to be extracted in the second row of data is:
DelDot2＝TolDot2*DelDot/Dot-TolDelDot1wherein TolDot2＝Dot1+Dot2
TolDelDot1＝DelDot1；Dot2And the total number of pixel points of the second line of jet printing data.
The number of pixel points to be extracted for the third row of data is:
DelDot3＝TolDot3*DelDot/Dot-TolDelDot2wherein TolDot3＝Dot1+Dot2+Dot3，
TolDelDot2＝DelDot1+DelDot2；Dot3And the total number of pixel points of the third row of jet printing data.
…………
And by analogy, the number of pixel points to be extracted in each row of data is calculated.
And step 303, calculating the number of the pixels to be extracted within the width of each continuous 1 of the data in each row according to the number of the pixels in each row of data, the number of the pixels to be extracted in each row of data and the width of each continuous 1 of the data in each row of data.
It should be noted that the number of pixel points to be extracted within the width of each continuous 1 segment of data in each row of data is calculated according to the following formula:
DelSecDotj＝TolWj*DelDoti/Doti-TolSecDelj-1，
wherein, DelSecDotjFor the number of pixel points to be extracted in the width of each continuous 1 of each section of data in each row of data, TolWjFor adding the sum of the width of the first segment data being 1 continuously to the width of the j segment data being 1 continuously, DeldotiThe number of pixel points, Dot, to be extracted for each line of dataiFor each row of pixel points, the number of corresponding pixel points in each row in the whole original spray printing data, TolSecDelj-1The number of pixel points that have been extracted in the line data.
That is, the number of the pixel points to be extracted within the width of the first segment data of the first row data being continuously 1 is:
DelSecDot1＝TolW1*DelDot1/Dot1-TolSecDel0wherein TolW1＝W1，TolSecDel0＝0；W1The width of the first segment data in the first row is continuously 1.
DelSecDot2＝TolW2*DelDot1/Dot1-TolSecDel1Wherein TolW2＝W1+W2，TolSecDel1＝DelSecDot1；W2The second segment of data in the first row is continuously 1 wide.
DelSecDot3＝TolW3*DelDot1/Dot1-TolSecDel2Wherein TolW3＝W1+W2+W3，TolSecDel2＝DelSecDot1+DelSecDot2；W3The third segment of data in the first row continues for a width of 1.
…………
And by analogy, the number of pixel points to be extracted in the width of each continuous 1 segment of data in the first row of data is calculated.
DelSecDot1＝TolW1*DelDot2/Dot2-TolSecDel0Wherein TolW1＝W1，TolSecDel0＝0；W1The width of the first segment data in the second row is continuously 1.
DelSecDot2＝TolW2*DelDot2/Dot2-TolSecDel1Wherein TolW2＝W1+W2，TolSecDel1＝DelSecDot1；W2The width of the second segment of data in the second row is continuously 1.
DelSecDot3＝TolW3*DelDot2/Dot2-TolSecDel2Wherein TolW3＝W1+W2+W3，TolSecDel2＝DelSecDot1+DelSecDot2；W3A width of 1 is continued for the third section data in the second row.
…………
And by analogy, the number of pixel points to be extracted in the width of each continuous 1 segment of data in the second row of data is calculated.
And finally, calculating the number of pixel points to be extracted within the width of continuously 1 per section of data in each row of data.
And 304, calculating the average width according to the number of the pixels needing to be extracted within the width of each continuous 1 of the data and the width of each continuous 1 of the data in each row of data, and extracting the pixels of each continuous 1 of the data according to the average width until the number of the extracted pixels reaches the number of the pixels needing to be extracted in each row of data.
It should be noted that the average width is obtained by rounding according to the following formula:
Stpj＝[Wj+(DelSecDotj-X)-1]/(DelSecDotj-X)，
wherein, StpjIs an average width, WjFor a width of 1 in succession for each piece of data, DelSecDotjThe number of pixel points to be extracted in the width of continuously 1 for each section of data in each row of data is X, and the number of pixel points extracted in the width of continuously 1 at present is X.
That is, pixel points are extracted according to the average width, starting from the position where the first data is 1 to the Stp-th data on the first data segment of the first linejRandomly extracting a pixel point, wherein the position of each pixel point behind is the position of the last extracted pixel point plus the StpjUntil at thatFinishing the extraction on the continuous width of 1, calculating the number X of the currently extracted pixel points after finishing the extraction, and obtaining the number of the pixel points which need to be extracted in the section as DelSecDotjX, so as to obtain a new average width, and so on until the number of points DelSecDot to be extracted for the segmentjAll the extraction is completed.
Step 305, setting the data corresponding to the extracted pixel points to 0.
That is, the extracted pixel point is set to 0, so that the data corresponding to the extracted pixel point is not subjected to jet printing.
As a specific example, it is assumed that the inkjet printing data is a black block picture with 100 × 100 pixels, and the current required inkjet printing density is 10%.
Then, the total number Dot of the pixels of the jet printing data is 100 × 100 ═ 10000;
total number Dot of pixel points of each line of jet printing datai＝100；
The total number of pixel points Deldot to be extracted is 10000 (100-10)/100 is 9000;
the number of the pixel points Deldot to be extracted in each row of datai＝90；
The number of pixel points DelSecDot to be extracted within the width of continuous 1 of the first segment of data in the first row of data1＝90；
For example as shown in table 1 below:
