Fig. 9 A has shown according to the embodiment among Fig. 8 to 9C, and the process of the compressing method of front edge printing is provided.
With reference to Fig. 9 A, in the paper feeding side when the fore-end of mobile paper P is positioned on the first brace summer 53a and be positioned at nozzle unit 62 times, the 62a of the first ink-jet of nozzle unit 62 makes that the front edge at the paper P between the first brace summer 53a partly prints., pollute in order to prevent the first brace summer 53a, in the middle of the data that the front edge part of paper P will be printed, part is corresponding to the data crested of the first brace summer 53a position, thereby produces first data herein.Therefore, in first process of the compressing method that provides front edge to print, data are only partly printed at the paper P between the first brace summer 53a.Reference marks P-A represents print area, finishes after first process finishes in this zone and prints first data.
With reference to Fig. 9 B, being used for after first process that front edge prints finishes shown in Fig. 9 A, in second stage, a half width of paper pushing motor swivel nozzle unit 62 makes paper P move to below the second portion 62b of nozzle unit 62.When the front edge of paper P partly arrives the second brace summer 53b of paper delivery side, produce second data of replenishing first data and print at print area P-B.When the first brace summer 53a and the second brace summer 53b are staggered and when second data produce and print,, thereby do not print in the paper P part that is positioned at the second brace summer 53b corresponding to the data crested of the second brace summer 53b position.Herein, second data are applied to the second portion 62b of nozzle unit 62, and data are applied to the 62a of first of nozzle unit 62, make that the compressing method according to routine prints on paper P.When the end of second process, front edge is printed and is finished.
According to this embodiment of the present invention, first and second data are to replenish the compressing method that concerns and print according to front edge at supplementary view along the scanning direction to print.
The compressing method that provides front edge to print of this embodiment can be applied to any structure, wherein brace summer is made the form to 7B as Fig. 4 A, the brace summer of the brace summer of perhaps paper feeding side and paper delivery side exchanges mutually and makes and to support paper P more effectively, and black gatherer is made the form of collecting China ink by the space between the brace summer.
Fig. 9 C has shown the 3rd process, finishes and after paper moves subsequently at the compressing method that first and second processes provide front edge to print, and prints according to the compressing method of routine.The first and second part 62a and the 62b ink-jet of nozzle unit 62 in conventional compressing method, feasible mid portion to paper P prints.Reference marks P-(A+B) representative is printed by the first and second process front edges and is finished print area afterwards.Reference marks P-C representative in the 3rd process according to conventional compressing method in zone that the mid portion of paper P prints.
Figure 10 A shows another embodiment according to the present invention to 10C, and the process of the compressing method of terminal edge printing is provided.
Shown in Figure 10 A, in conventional compressing method, the first and second part 62a and 62b ink-jet by nozzle unit 62 print.Afterwards shown in Figure 10 B, when the terminal edge of paper P moves to below the nozzle unit 62, except that the paper P part that is positioned at the first brace summer 53a, printing of paper P.For this operation, will be in the middle of the data that the end portion of paper P is printed, first data that produce by the data of covering corresponding to the first brace summer 53a position be applied to the 62a of first of nozzle unit 62.Reference marks P-E representative has been carried out the zone of printing according to conventional compressing method.Reference marks P-F represents according to embodiment of the present invention, the print area after compressing method first process that terminal edge is printed is finished.
After finishing first process, a half-distance of paper P moving nozzle unit 62 width.Then, shown in Figure 10 C, second data of replenishing first data are applied to the second portion 62b of nozzle unit 62, thereby in second process, the terminal edge that is positioned at the paper P on the second brace summer 53b in the paper feeding side partly prints.Print area P-G in second process is positioned on second brace summer, it and the print area P-F relation of complementing one another in first process.
Figure 11 A shows according to the embodiment of the present invention to 11C, the frisket embodiment that uses in the compressing method of edge printing is provided.Each frisket embodiment illustrates by the hexadecimal digit system.
When execution does not have the edge printing of margin, the boundary line can occur between the print area P-A of Fig. 9 B and the P-B and between the print area P-F of Figure 10 C and the P-G, thereby make image quality decrease.In other words, when execution provides the compressing method of edge printing, do not print continuously at print area P-A and P-B or P-F and P-G, thereby the China ink that is sprayed onto on the paper P became dry in the different time.Therefore, between these print areas the boundary line appears.In order to address this problem, the invention provides frisket, it filters out the view data of edge printing.
Frisket is paired, and the paired frisket relation of complementing one another.Therefore, complete image only just can form after all handling at frisket.In the edge printing process, a frisket of frisket centering along the scanning direction repeatedly as a grating, and another of frisket centering along this scanning direction repeatedly as another grating, make to form complete image.In each frisket, along 100% print line 1 of nozzle unit scanning direction print image data and the not 0% print line 0 periodically repetition always of print image data.Data corresponding to the brace summer position filter out by continuing to repeat 0% print line 0, make to stop brace summer to pollute.
With reference to Figure 11 A, when the brace summer in the paper feeding side was positioned at the 0% print area 74a of the first frisket 91a, 0% row 0 of this frisket were to continue to repeat, and are positioned at the 0% print area 74b of the second frisket 91b at the brace summer of paper delivery side.In both sides from each 0 % print area 74a and 74b edge, quantity with 0% print line 0 of 100% print line, 1 alternatively distributed order, change gradually in mode, make to stop image quality decrease at 0 % print area 74a and 74b both sides with 100% print line inverse ratio.From each 100 % print area 76a and 76b edge, 0% print line 0 distributes according to above-mentioned identical mode with 100% print line 1, makes image quality decrease be stoped in both sides.
In Figure 11 B, the first frisket 81a and the second frisket 81b have data rows complementary in the hexadecimal digit system respectively.Respectively between 100 % print area 86a and 86b and 0 % print area 84a and 84b, quantity with 0% print line 0 of 100% print line, 1 alternatively distributed order, change gradually in mode, make image quality decrease be stoped with 100% print line inverse ratio.
