Ink 100 is told to form printing zone A1.Then, stagger to than printing zone A1 by conveying direction upstream side so as to form print
Brush region A2.Now, stagger printing zone A2 amount for printing zone A1 length L 1/4.That is, printing zone A1 and printing
The 3/4 of region A2 length L is overlapping, and the 1/4 of the length that staggers L.In printing equipment 1, be identically formed printing zone A3, A4, A5,
A6。
Hereinafter, carried out with the image that the dot density (density of drop) to image is the black (K) 12% of yellow (Y) 100%
Illustrated in case of printing.In addition, in this case, as one, the 100% of yellow and the 12% of black at four
Path is printed by impartial Ground Split, and the ratio of yellow (Y) and black (K) in each path is all 25: 3.Hereinafter, by the ratio
Ink be referred to as " ink 100C ".
Even if in addition, using identical ink, in the ink of situation about being printed on not printed processed goods W
Infiltration mode is different with the infiltration mode of situation about being printed on the processed goods W being printed.Therefore, it has been formed
The color of printing zone is made by being printed to the so far not printed part in the region, or is printed onto and is printed
The part of brush and be made, and color change.
Hereinafter, it is that 25: 3 ink 100C prints on also not printed processed goods W by the ratio of yellow and black
Formed by region color as color a, will the color in region formed by printing be made again after ink 100 has been printed
For color b.
In printing equipment 1, when the printing of first path finishes, in printing zone A1, whole region is color
a.When the printing in the second path finishes, the color in the region in printing zone A1 downstream 1/4 is also color a.In addition, print
The color for brushing the region A1 regions overlapping with printing zone A2 is color a+b.Also, the area of printing zone A2 upstream side 1/4
Domain is color a."+" shows that color is overlapped.
At the end of the printing in the 3rd path, in printing zone A1, the color in 1/4 region in downstream is color a,
The color in region overlapping with printing zone A2 printing zone A1 is color a+b.In addition, in printing zone A1, printing zone A2
It is color a+b+b (color a+2b) in the region overlapping with printing zone A3.In addition, in only printing zone A2 and Printing Zone
It is color a+b in region overlapping domain A3.Also, it is color a in the region that only printing zone A3 has been printed.
If similarly printed, when the printing in the 4th path finishes, color a, color a+b, color a+2b, face
Color a+3b, color a+2b, color a+b, color a region are arranged in order from downstream.When the printing in the 5th path finishes
When, color a, color a+b, color a+2b, color a+3b, color a+3b, color a+2b, color a+b, color a region under
Trip side is arranged in order.When the printing in the 6th path finishes, color a, color a+b, color a+2b, color a+3b, color a
+ 3b, color a+3b, color a+2b, color a+b, color a region are arranged in order from downstream.
In printing equipment 1, the color of ink 100 is that color a+3b region is the part as actual product, color
A, color a+b and color a+2b part go out of use.In this way, in printing equipment 1, being obtained by the printing in the 4th path and being used as product
Part, become big as the region of the part of product in the printing after the 5th path.
In addition, in general printing equipment, in the case where shooing out ink towards arbitrary position, in forward path and
Drop point site in return path in ink misplaces.Because acting on ink in forward path and return path
The direction of inertia force is different.Especially, once the size of the drop of ink is smaller or nozzle and the spacing distance of recording medium ratio
Larger, then the drop point site in ink in forward path and return path significantly easily misplaces.In such dislocation
In the case of generation, as in order to reduce the unit of the dislocation, it is considered to " path displacement " described below.
Hereinafter, one shifted to the path of printing equipment 1 illustrates.Hereinafter, on yellow (Y) and black (K)
The situation of 100 pairs of progress path displacements of the ink of black (K) is illustrated among ink 100.
, will be in first path, the 3rd path and the 4th path in the path of first path~the 4th in printing equipment 1
In black (K) the ink 100K that shoots out shootd out in the second path.That is, carry out change shoot out position shoot out position change correction
(path displacement).
By carrying out shooing out position change correction, before correction be 25: 3 each path in yellow (Y) and black (K)
Ratio is 25: 0 for the yellow (Y) and the ratio of black (K) in first path.Yellow (Y) and black in the second path

In the image for having carried out such path displacement, color a+2b+d and color 3b+c region are that actual turn into produces
The part of product, remainder goes out of use.In addition, by carrying out path displacement, three paths among four paths can be omitted in
Printing, therefore, it is possible to the dislocation for the drop point site for reducing the foregoing ink 100 in forward path and return path.
Also, the ink 100 that passage path displacement is eliminated is assigned to other paths, therefore when seeing that image is overall, ink 100
Total jetting amount is identical, and the image quality aggravation of image is difficult to occur.
Even if however, carried out path displacement, if color a+2b+d region and color 3b+c region hue difference
Than larger, then in the actually part as product, striped is uneven to be occurred, and image quality aggravation occurs.Exist in the presence of the image quality aggravation
The possibility significantly embodied when color a and color b difference and big color c and color d difference.
In printing equipment 1, it can prevent because the path shifts the image quality aggravation of the image produced.It is carried out below
Explanation.
As shown in figure 5, in printing equipment 1, when path is shifted, in printing zone A1, in whole region, yellow
And the ratio of black (K) is that 25: 0 ink 100A is shootd out (Y).
In addition, in printing zone A2, when along the conveying direction quartering, in the region A21 in downstream to 3/4,
Yellow (Y) and the ratio of black (K) are that 25: 12 ink 100B is shootd out.Also, the 1/4 of printing zone A2 upstream side
Region A22 in, ink 100A is shootd out.
In addition, in printing zone A3, when along the conveying direction quartering, in the region A31 in downstream to 1/2,
Ink 100A is shootd out.In addition, in the 1/4 of region A31 upstream side region A32, ink 100B is shootd out.In addition,
In the region A33 of the 1/4 of region A32 upstream side, ink 100A is shootd out.
In printing zone A4, in whole region, the ratio of yellow (Y) and black (K) is 25: 0 ink 100A quilts
Shoot out.
Shifted by such path, ink 100B can be omitted and fall directly on part on processed goods W, in printing zone
Ink 100B that A2 and printing zone A3 have been shootd out and ink 100A overlappingly land.That is, ink 100B is in printing zone A1
The overlapping portion that~A4 coincides with one another is shootd out.Therefore, as shown in fig. 6, when can prevent that ink 100B from falling directly on processed goods W
Color c occur.Thus, although having carried out path displacement, the color really as the part of product only turns into color a+2b+d.
Thus, it is possible to prevent what is caused by the color a+2b+d and the difference of color 3b+c color produced by the displacement of existing path
Image quality aggravation.As a result, in printing equipment 1, even if having carried out path displacement, can also form the high figure of printing precision
