Embodiment 1：
As shown in figure 1, the present embodiment provides a kind of method for improving digital inkjet printer printing quality, in numeral
Ink-jet printer gag somebody phenomenon when, improve its printing quality, methods described comprises the following steps：
S101. the gray level that can be showed according to the printing machine obtains the situation of gaging somebody being likely to occur, wherein, often
Plant gray value of the situation of gaging somebody including place site left side site of gaging somebody, the desired gray level value of place site of gaging somebody and gag somebody and locate the site right side
The gray value of side site.
For example, the printing machine can show 6 grades of gray levels, the then site that wherein each nozzle is formed in printing body
6 grades of gray values can be showed, if any one nozzle is gaged somebody phenomenon in the printing machine, place site left side site of gaging somebody
Gray value, gag somebody place site desired gray level value and gag somebody place site right side site gray value have 63 kinds of feelings in theory
Condition, respectively (1,1,1), (1,1,2), (1,1,3), (1, Isosorbide-5-Nitrae), (1,1,5), (1,1,6), (1,2,1), (1,2,2) ... (6
6,6), above-mentioned 63 kinds of situations are the printing machine and can show the situation of gaging somebody being likely to occur during 6 grades of gray levels.It is described
Desired gray level value refer to the gaging somebody nozzle of phenomenon of place site of gaging somebody wishes the gray scale of the site formed in printing body
Value, correspondingly, the actual grey value of place site of gaging somebody is zero.
S102. the desired gray level value of place site of gaging somebody in every kind of situation of gaging somebody is set to zero, and is increased step by step respectively described
Gag somebody and locate the gray value of site left side site, right side site and left and right sides site, until reach the printing machine can show
Gray level higher limit, to draw all Repair Parameters of every kind of situation of gaging somebody.
For example, the printing machine can show 6 grades of gray levels, then its gray level higher limit is 6；If place site of gaging somebody is left
The gray value of side site is 5, and the desired gray level value of place site of gaging somebody is 3, and the gray value of place site right side site of gaging somebody is 4, i.e.,
For (5,3,4), then when the Repair Parameters of the situation of gaging somebody are calculated, will first gag somebody the situation of gaging somebody place site in the situation of gaging somebody
Desired gray level value be set to 0, form the corresponding situation of gaging somebody (5,0,4) for actually occurring of the situation of gaging somebody, then be with (5,0,4)
The gray value for locating site left side site is gaged somebody up to reaching gray level higher limit 6 in basis described in increasing step by step, the repairing ginseng for drawing
Number is (6,0,4), then increasing the gray value of the place site right side site of gaging somebody based on (5,0,4) step by step up to reaching
Gray level higher limit 6, the Repair Parameters for drawing are (5,0,5) and (5,0,6), finally increasing institute step by step based on (5,0,4)
The gray value of place site left and right sides site of gaging somebody is stated until reaching gray level higher limit 6, the Repair Parameters for drawing are (6,0,5)
(6,0,6), namely situation of gaging somebody (5,3,4) all Repair Parameters be respectively (6,0,4), (5,0,5), (5,0,6), (6,
0,5) with (6,0,6).
S103. all Repair Parameters of every kind of gag somebody situation and every kind of situation of gaging somebody are filled empty to a width without overlapping
In white image, to generate several test charts to be printed corresponding with every kind of situation of gaging somebody respectively.
That is, filled with corresponding gag somebody situation and its all Repair Parameters in every kind of test chart to be printed.As for tool
Body filling mode, can be by those skilled in the art's sets itself.For example, can be by each of a kind of situation of gaging somebody, the situation of gaging somebody
Repair Parameters repeat any three row of filling to blank image respectively without overlapping（Or three rows）In neighbour node, with feelings of gaging somebody
Said as a example by condition (5,3,4) and its all Repair Parameters (6,0,4), (5,0,5), (5,0,6), (6,0,5) and (6,0,6)
Bright, three gray values 5,3 and 4 that can include the situation of gaging somebody (5,3,4) repeat filling to the 1st~3 row site of blank image
In, and every a line in the 1st~3 row is sequentially filled gray value 5,3 and 4, then three that Repair Parameters (6,0,4) are included
Gray value 6,0 and 4 repeat filling to blank image the 4th~6 row site in, and it is described 4th~6 row in every a line fill out successively
Gray value 6,0 and 4 is filled, the rest may be inferred, all Repair Parameters are filled into blank image.Certainly, can also be filled out using other
Fill mode and gag somebody situation and its all Repair Parameters fill into blank image to form corresponding test chart to be printed by every kind of.
Site in the blank image（Alternatively referred to as pixel）Gray level be site and plane in zero, and the blank image
Dot matrix image（The picture format that i.e. digital inkjet printer can print）In site shape, size all same.
Preferably, the blank image is shaped as rectangle；The width of the blank image is less than or equal to the printing
A quantity for the nozzle of ink gun in machine, the width of the length less than or equal to the printing machine printer page of the blank image
Face length.It is so designed that the selection for facilitating optimal Repair Parameters in test map generalization to be printed and subsequent step.
Wherein, the step s103 is specially：
S103-11. by the gray value of place site left side site of gaging somebody in every kind of situation of gaging somebody, the ideal ash of place site of gaging somebody
The gray value of angle value and place site right side site of gaging somebody is repeated in filling to each row/column of a width blank image, and each column/
The gray value all same of filling in row, it is to generate several pending test charts corresponding with every kind of situation of gaging somebody respectively, i.e., every kind of
Situation of gaging somebody corresponds to a pending test chart.
To be described as a example by the situation of gaging somebody (5,3,4), three gray values 5,3 that the situation of gaging somebody (5,3,4) can be included
With 4 be repeated in filling to the gray value in each row of a width blank image, namely after filling per a line with 5,3,4,5,3,
4th, 5 ... mode is arranged, and after filling each row gray value all same, be 5,3 or 4.
It should be noted that in this step, if each gray value is repeated in filling to each row of a width blank image,
The gray value all same of filling in each column；If each gray value is repeated in filling to each row of a width blank image, often go
The gray value all same of interior filling.
S103-12. the gray value in each Repair Parameters of every kind of situation of gaging somebody is repeated respectively to replace the situation of gaging somebody
The gray value of three different column/row neighbour nodes in corresponding pending test chart（I.e. each Repair Parameters corresponds to different
Three column/row neighbour nodes）, and make to be that zero gray value repeats to replace corresponding three column/rows neighbour node in each Repair Parameters
In gag somebody the desired gray level value of place site, to generate several test charts to be printed corresponding with every kind of situation of gaging somebody respectively, and often
It is separated by a number of site between adjacent three column/row sites being replaced in test chart to be printed.
To be described as a example by the Repair Parameters (6,0,5) of the situation of gaging somebody (5,3,4), by Repair Parameters (6,0,5)
Gray value 6,0 and 5 repeats to replace the gray value of three row neighbour nodes in pending test chart, and every in the three row neighbour node
The gray value of row site is respectively 5,3 and 4, that is, all gray values 5 in making gray value 6 replace the three row neighbour node,
All gray values 3 in making gray value 0 replace the three row neighbour node, in making gray value 5 replace the three row neighbour node
All gray values 4, then the gray value of every row site is respectively 6,0 and 5 in three row neighbour nodes after replacing.
Preferably, the site being separated by between three column/row sites being replaced adjacent in described every test chart to be printed
Number is identical, to reach the best visual effect, is easy to the selection of the optimal Repair Parameters of every kind of situation of gaging somebody in subsequent step.
If it should be noted that in step s103-11, site left side site is located by gaging somebody in every kind of situation of gaging somebody
It is empty to a width that the gray value of gray value, the desired gray level value of place site of gaging somebody and place site right side site of gaging somebody is repeated in filling
In each row of white image, then step weighs the gray value in each Repair Parameters of every kind of situation of gaging somebody in s103-12 respectively
The gray value of three row neighbour nodes in the corresponding pending test chart of the situation of gaging somebody is replaced again；If in step s103-11,
By the gray value of place site left side site of gaging somebody in every kind of situation of gaging somebody, the desired gray level value of place site of gaging somebody and place site of gaging somebody
The gray value of right side site is repeated in filling to each row of a width blank image, then in step s103-12, will be every kind of stifled
Gray value in each Repair Parameters of mouth situation repeats to replace three rows in the corresponding pending test chart of the situation of gaging somebody respectively
The gray value of neighbour node.
Or, the step s103 is specially：
S103-21. by the gray value of place site left side site of gaging somebody in every kind of situation of gaging somebody, the ideal ash of place site of gaging somebody
