The specific embodiment
Below in conjunction with Figure of description the embodiment of the invention is elaborated.
As shown in Figure 2, in the embodiment of the invention, the flow process that image-forming block is handled synchronously in a kind of single PASS digital printing equipment is as follows:
Among the embodiment, step 201 is when implementing, can there be the several different methods body of determining to undertake the printing of arrive to set benchmark, be example now with the benchmark arriving signal, the body of undertaking the printing of produces corresponding benchmark arriving signal when arriving described setting benchmark, when detecting the benchmark arriving signal, the body of determining to undertake the printing of arrives described setting benchmark.
During enforcement, set benchmark multiple implementation can be arranged, for example, can select for use an object as object of reference, also virtual sign or line of demarcation can be set, can also utilize the characteristic of some equipment, be example with the sensor, have following characteristic: object is through sensor the time, and the induction side detects the signal less than the emitting side emission; Usually adopt photoelectric sensor or color mark sensor.In actual applications, it is normally changeless to set benchmark, hereinafter describes for convenient, can be called absolute standard with setting benchmark.
In one embodiment, step 202 by described setting benchmark, is handled first image-forming block of each image-forming block group when implementing synchronously.Illustrate, as shown in Figure 3, there be S image-forming block group in single PASS high speed digital printing equipment, each image-forming block group is respectively L1, L2......Ls with the spacing of setting benchmark, each image-forming block group and the spacing of setting benchmark and inequality, and between this S the image-forming block group is relatively independent, and this has just guaranteed the flexibility between the image-forming block group.
Among the embodiment, the body of undertaking the printing of is one page at least, and each body of undertaking the printing of all produces a benchmark arriving signal when arriving described setting benchmark; After detecting the benchmark arriving signal, store this benchmark arriving signal; The body of determining to undertake the printing of arrives before first image-forming block of each image-forming block group, also comprises: the benchmark arriving signal that reads storage; According to the spacing of the benchmark arriving signal that reads, each first image-forming block of image-forming block group and described setting benchmark, the body of determining to undertake the printing of is through setting first image-forming block required time that benchmark arrives each image-forming block group.
Detailed description below cites an actual example: for making things convenient for timing, during enforcement, a permanent timer is set, is used for synchronised clock; The body of undertaking the printing of arrives and produces a benchmark arriving signal and storage when setting benchmark, the value of record permanent timer this moment.After reading a benchmark arriving signal, detect the moment that produces the benchmark arriving signal and the moment that reads this benchmark arriving signal, obtain both differences; First image-forming block according to each image-forming block group obtains determining to undertake the printing of body through setting first image-forming block required time that benchmark arrives each image-forming block group with the spacing of setting benchmark; Above-mentioned difference and required time are made comparisons, and the body that obtains undertaking the printing of arrives the moment of first image-forming block of each image-forming block.
Among the embodiment, each image-forming block in each image-forming block group, after the processing synchronously when arriving, the body of undertaking the printing of is printed processing.During enforcement,, first image-forming block of each image-forming block group is handled synchronously by setting benchmark.After handling synchronously, through setting first image-forming block required time that benchmark arrives each image-forming block group, the body of determining to undertake the printing of arrives first image-forming block of each image-forming block group according to the body of undertaking the printing of; First image-forming block of each image-forming block group prints processing.
First image-forming block of each image-forming block group begins to print processing, and other image-forming blocks of each image-forming block group are handled synchronously.Among the embodiment, step 203 is when implementing, and for reaching the purpose that improves resolution ratio, each image-forming block group is spliced by a plurality of image-forming blocks.In each image-forming block group, except that first image-forming block, on the body direction of motion of undertaking the printing of, be benchmark with the previous image-forming block after the synchronous processing successively, a back image-forming block is handled synchronously.In actual applications, each image-forming block is a benchmark with last image-forming block all, and benchmark is in variable condition, hereinafter describes for convenient, also this benchmark can be called relative datum.
In sum, the image-forming block synchronization processing method can be thought the synchronization processing method that a kind of absolute standard combines with relative datum in single PASS digital printing equipment that the embodiment of the invention provides, by absolute standard first image-forming block of each image-forming block group is handled synchronously, other image-forming blocks in the image-forming block group are handled synchronously by relative datum.
When each image-forming block group adopts the mode of a plurality of image-forming block splicings to realize, in the image-forming block group, the spacing between last image-forming block and back one image-forming block can be set, as, can be set at fixed width, also can be set at both physical widths.Be that example describes now with the physical width that is set at both, can according to the physical width of image-forming block determine to undertake the printing of body through last image-forming block to after an image-forming block required time.In each image-forming block group, according to the body image-forming block required time after last image-forming block arrives of undertaking the printing of, the body of determining to undertake the printing of arrives back one image-forming block; Described back one image-forming block prints processing.
Lifting an example describes, suppose that each image-forming block group is made up of N image-forming block, the arrangement mode of each image-forming block as shown in Figure 4, so, from the body travel direction of undertaking the printing of, in an image-forming block group, for the data on the same straight line, when the body of undertaking the printing of arrived first image-forming block of this image-forming block group, first image-forming block began to print, and was that second image-forming block begins to print then ... be that N image-forming block begins to print at last.During enforcement, other image-forming blocks in the image-forming block group except that first image-forming block, on the body direction of motion of undertaking the printing of, with that image-forming block that comes own front is benchmark, promptly, second image-forming block is benchmark with first image-forming block, and the 3rd image-forming block is benchmark with second image-forming block ... N image-forming block is benchmark with N-1 image-forming block.Synchronization processing method in other image-forming block groups is similar.
Because inner the employing with last image-forming block of image-forming block group is the method for synchronous of benchmark, in fact, the benchmark of the just whole image-forming block group of first image-forming block of each image-forming block group, that is to say, want each image-forming block group synchronously, only need first image-forming block of each image-forming block group synchronously, simplified whole method for synchronous, be easy to realize, compare with the benchmark that available technology adopting is directly unified, reduced the timing duration of each image-forming block, can save system resource and take.
Among the embodiment, the imaging unit of each image-forming block can have multiple, for example is that unit prints processing with the page or leaf, or is that unit prints processing with a task, and existing is that unit describes with the page or leaf.During enforcement, when first image-forming block begins imaging Y (Y is a natural number) page data, second image-forming block imaging Y-1 page or leaf.For each image-forming block is provided with the page length counter, be used to count the page length that needs are printed, determine the concluding time that each image-forming block is printed.When the page length rolling counters forward of an image-forming block during to the page length that needs to print, this image-forming block stops to print.
In embodiments of the present invention, not only can handle the body of undertaking the printing of is the printing of one page, can also handle the situation of continuous printing multipage, has improved printing effect.Concrete processing procedure is as follows: in an image-forming block group, when first image-forming block begins to print, second image-forming block handled synchronously, and with first image-forming block just at the page length of the page or leaf of imaging as the page length of second image-forming block imaging page or leaf.When the page length rolling counters forward of first image-forming block during to the page length that needs to print, first image-forming block print state finishes, and the printing of proceeding down one page responds.When the body of undertaking the printing of arrived second image-forming block, second image-forming block began to print, the 3rd image-forming block handled synchronously, and with second image-forming block just at the page length of the page or leaf of imaging page length as the imaging page or leaf of the 3rd image-forming block.By that analogy, when N-1 image-forming assembly begins to print, N image-forming block handled synchronously, and with N-1 image-forming block just at the page length of the page or leaf of imaging as the page length of N image-forming block imaging page or leaf.When the page length rolling counters forward of N-1 image-forming block during to the page length that needs to print, N-1 image-forming block print state finishes, when the page length rolling counters forward of N image-forming block during to the page length that needs to print, N image-forming block print state finishes, and continues the response printing response of one page down.Arrive this, a page data just complete imaging finishes.Repeat said process, carry out the imaging of next page data.
Below the synchronous method of image-forming block in a kind of single PASS digital printing equipment is specifically described: to all image-forming blocks in the whole digital printing equipment divide into groups, the classification management by synchronization, synchronously after each image-forming block group, synchronous other image-forming block in each image-forming block group, with between first image-forming block that is reduced to each image-forming block group synchronously of all image-forming block groups synchronously.Lift an example, equipment as shown in Figure 3, Figure 4, from the body travel direction of undertaking the printing of, when the body of undertaking the printing of arrives benchmark, it is synchronous to carry out each image-forming block group, and when the body of undertaking the printing of arrived image-forming block group X of L value minimum, first image-forming block of X image-forming block group began to print, and, begin to carry out the synchronous processing of the image-forming block of this image-forming block group inside.When the body of undertaking the printing of moved to second image-forming block in this image-forming block group inside, second image-forming block began to print, and simultaneously, carried out the synchronous of the 3rd image-forming block, and the rest may be inferred, finished synchronous processing until the inner all image-forming blocks of this image-forming block group.The synchronous processing mode of the image-forming block of other image-forming block group inside is similar.
For improving the flexibility of the synchronization processing method of image-forming block in single PASS digital printing equipment that the embodiment of the invention provides, can also utilize register file that the spacing between each image-forming block in each image-forming block group is set in real time, promptly, in the image-forming block group, on the body direction of motion of undertaking the printing of, the spacing between back one image-forming block and the last image-forming block.Register file can also be used to storing the spacing of each image-forming block group and described setting benchmark, that is, and and the spacing between first image-forming block of each image-forming block group and the described setting benchmark.
