As shown in Figure 1, agreement is from the fabric width direction earlier, form as the parts group by S, from the resolution direction, every composition has N image-forming block as the parts group, also arrange in the digital printing equipment, the numbering of image-forming block group from left to right is followed successively by 1 to S, and the numbering of image-forming block is followed successively by 1 to N from the resolution direction in each image-forming block group.

Data in the input data allocations unit are to import with the behavior unit in the dot array data, at first bitstream data enters into the fabric width distribution subelement of data allocations unit, group counting number module in this subelement can be set to a group counter in actual applications, this group counter can adopt and add counting, also can adopt to subtract counting.Add counting if the group counter adopts, the initial value of then organizing counter is made as 0, when the counting of group counter represents that data line disposes during for S, at this moment, to organize the counter initialization, and also be about to count status and be classified as 0, and continue to handle the next line data according to top method; Subtract counting if the group counter adopts, the initial value of then organizing counter is made as S, represents that data line disposes when the counting of group counter is 0, at this moment, to organize the counter initialization, and also be about to count status and be classified as S, and continue to handle the next line data according to top method; The wide counting module of group in this subelement can be set to a wide counter of group in actual applications, this processing procedure of organizing wide counter is consistent with the processing procedure of aforementioned group of counter, difference is that this counter is the actual use width according to the image-forming block group of correspondence, and the bitstream data that flows into is counted.

During explanation below carrying out, if the count value of group counter is that (the expression current data is the data of X image-forming block group to X, wherein, X is more than or equal to 1, smaller or equal to S), the actual width that uses of an X image-forming block group is U, the group counter adopts and adds counting, organizes wide counter employing subtracting counting.

When handling imaging data, according to the value after the count status decoding of group counter, the actual use width U of X image-forming block group in the call parameters storage unit, and the U value offered organize wide counter, organize wide counter its initial value is made as U.Because the value of the actual use width register storage of each image-forming block group is bitwise, so when organizing wide rolling counters forward also is bitwise, the data of a bit of every input, the count value of organizing wide counter subtracts 1, and this count value is offered comparison module; Comparison module is set to 0 according to the method for counting threshold value that the wide counter of group adopts, and count value and this threshold value that will organize wide counter and provide compare, when the count value of the wide counter of group is not equal to 0, the data that expression belongs to X image-forming block group also do not enter into the circuit of X image-forming block group fully, according to deciphering the decoding value that obtains to the counting of group counter, generate control signal A, this control signal A is used for controlling the circuit that the data that belong to X image-forming block group flow into X image-forming block group; When the count value of the wide counter of group equals 0, the data that expression belongs to X image-forming block group all enter into the circuit of X image-forming block group, the count value of triggering this moment group counter adds 1, be that saltus step is X+1, continue to handle the data of X+1 image-forming block group according to top method, all assign up to the data of S image-forming block group.

Fabric width distributes subelement that the data and the control signal A of X image-forming block group are offered invalid data distribution subelement, group counting number module in this subelement also can be set to a group counter when practical application, concrete processing procedure distributes the group counter description in the subelement consistent with above-mentioned fabric width, is not described in detail herein; The left side in this subelement is not used the width counting module can be set to the left side and is not used the width counter, the description of this counter is consistent with the front, difference be this counter be according to each image-forming block group left side do not use width and to the input the invalid data position count.

During explanation below carrying out, what establish input is the data of X image-forming block group, and the left side of X image-forming block group does not use width to be R, and the group counter adopts and adds counting, and the left side does not use the width counter to adopt to subtract counting.

According to the value after the count status decoding of group counter, select the left side of X image-forming block group in the parameter storage unit not use width R, and the R value is offered the left side do not use the width counter, the left side does not use the width counter that its initial value is made as R, because it is bitwise that the value of width register storage is not used on the left side of each image-forming block group, so also be bitwise when the width gauge rolling counters forward is not used on the left side, it is the invalid data of a bit of every input, the left side does not use the count value of width counter to subtract 1, and this count value is offered first comparison module; The method of counting threshold value that first comparison module does not use the width counter to adopt according to the left side is set to 0, the value and 0 of not using the width counter to provide on the left side compares, when the left side does not use the count value of width counter to be not equal to 0, represent that X the image-forming block group left side do not use the imaging point in the width also replenish to go up invalid data fully, according to the count value of group counter is deciphered the decoding value that obtains, generate control signal B, this control signal B is used for controlling invalid data and adds to the imaging point that width is not used on X the image-forming block group left side; When the left side does not use the count value of width counter to equal 0, represent that the imaging point that does not use width in X the image-forming block group left side has replenished fully and go up invalid data, the count value of triggering this moment group counter adds 1, be that saltus step is X+1, continue to utilize invalid data to replenish X+1 the untapped imaging point in the image-forming block group left side according to top method, all replenish up to the untapped imaging point in the left side of S image-forming block group and finish.

For dirigibility and the accuracy that increases system, after finishing above-mentioned steps, after also being about to belong in the circuit that the bitstream data of X image-forming block group and invalid data that width is not used on the left side be assigned to X image-forming block group, do not use width and the right not to use the count value addition of width counter on actual use width, the left side of X image-forming block group, with be Sum, wherein, not use the initial value of width counter be zero on the right.Then Sum is input to second comparison module, with the physical width P of X image-forming block group in the parameter storage unit relatively, if Sum is less than P, illustrate that so current image-forming block group the right also has the not additional imaging point that finishes, be used to control the control signal B that determined invalid data position is assigned to corresponding image-forming block group according to the count value of group counter being deciphered the decoding value that obtains, generating; Continuation is input to invalid data in the circuit of X image-forming block group, clear data position of every input, and the right does not use the count value of width counter to add 1.When Sum equals P, illustrate that all the untapped imaging points in X the image-forming block group have all been supplied, the count value of group counter adds 1, i.e. and saltus step is X+1, according to said process, continues to handle the data of next image-forming block group.

Do not use width threshold value to compare on the sampled value and the described left side of described invalid data position, when the sampled value of described invalid data position does not use width threshold value to equate with the described left side, control the image-forming block group of described bitstream data correspondence and count saltus step; When the sampled value of described invalid data position and the described left side do not use width threshold value unequal, according to the sampled value of described image-forming block group number is deciphered the decode results that obtains, generation is used to control the control signal that determined invalid data position is assigned to corresponding image-forming block group.

18. disposal route as claimed in claim 17, it is characterized in that, the physical width of described image-forming block group according to described bitstream data correspondence and the actual width that uses, determine the not use width of described image-forming block group, according to the described width that do not use, determine the invalid data position that will replenish, and be used to control the control signal that determined invalid data position is assigned to corresponding image-forming block group, also comprise according to definite result's generation:

Do not use width according to the physical width of the image-forming block group of described bitstream data correspondence, the actual width and the described left side of using, determine that the right of described image-forming block group do not use width, width is not used on the right according to described image-forming block group, determine the invalid data position that to replenish, and sampled in the invalid data position of input;

The actual use width of described image-forming block group, the described left side are not used the sampled value addition of width and described invalid data position;

The value that described addition is obtained and the physical width of described image-forming block group compare, and when the value that obtains when described addition and the physical width of described image-forming block group equate, control the image-forming block group of determined bitstream data correspondence and count saltus step; When the value that obtains when described addition is not equal to the physical width of described image-forming block group, according to the sampled value of described image-forming block group number is deciphered the decode results that obtains, generation is used to control the control signal that determined invalid data position is assigned to corresponding image-forming block group.

19. disposal route as claimed in claim 12 is characterized in that, described systematic parameter comprises:
