The print control program of the present embodiment is based on thinking: in print procedure, if there is some color face image
When the nozzle right set of data is neat inaccurate, the left null value of corresponding color face image data is adjusted, by real-time online to reach each
The nozzle right of a color face image data covers neat purpose.
Spray head physical location due to printing not homochromy face image data discharges difference, after starting printing, chooses default
Printing one of color face image data spray head be with reference to i.e. using the color face image data of the nozzle printing as reference,
He is compared its allochromatic colour face image data of nozzle printing with the reference color face image data of the nozzle printing, if there is a left side
The right neat error of set monitors that not homochromy face image data print result left and right occurs and do not cover neat phenomenon, then triggering is to color face
Image data or so covers the adjustment process of neat error.
In particular it is necessary to determine its allochromatic colour face image data, that is, each color face to be adjusted image data relative to reference color face
The error transfer factor value of image data, that is, the left empty adjusted value relative to reference color face image data.
The determination process of the left empty adjusted value is as follows:
If certain the color face image printed compared with the evening printing of reference color face image, illustrates the color face in the lateral direction
The color face image data of image needs to adjust, at this time since its corresponding color face to be adjusted image data is relative to reference color face figure
As data occur deviating to the right in the lateral direction, it is determined that corresponding left empty adjusted value is negative value, is used to indicate corresponding
Spray head reduces the left null value of the i.e. initial setting up of left null value according to the left empty adjusted value, reduces corresponding spray head by left empty adjusted value left
Empty length is started to print the subsequent color face image data in advance by left empty adjusted value.
Opposite, if certain the color face image printed is said in the lateral direction compared with the morning printing of reference color face image
The color face image data of the bright color face image needs to adjust, at this time since its corresponding color face to be adjusted image data is relative to ginseng
It examines color face image data to occur deviating to the left in the lateral direction, it is determined that corresponding left empty adjusted value is positive value, for referring to
Show that corresponding spray head increases left null value according to the left empty adjusted value, increase corresponding spray head by the length of left sky by left empty adjusted value,
The subsequent color face image data is printed by left empty adjusted value delay.It can be covered together with reaching the image or so of each color face printing
Purpose, printing later all printed by left null value adjusted.
Wherein, the determination of above-mentioned left empty adjusted value can be measured by measuring instrument the color face image respectively printed relative to
The opposite offset distance of reference color face image, and then according to the corresponding relationship of the offset distance and the print range of each nozzle, really
Corresponding nozzle number is made, to determine that right and left adjusts upward how many a nozzles.
It is worth noting that discovery verso images and direct picture or so chromatography is uneven if it is front and back sides duplex printing
When, some positive color face image can be chosen as reference, each color face image data and the front for printing reverse side are beaten
The reference color face image data of print is compared, and carries out left null value adjustment to each color face image data of reverse side, method of adjustment with
It is above-mentioned identical.
It should be noted that in digital printing print procedure being printed as unit of a line, a line number is according to by a left side
Null value+valid data+right null value composition, it is uneven there are when error in the left and right printing set for finding each spray head, it does not need to shut down
Adjust spray head physical location, but change print image, made by changing left null value in real time online image integrally move to left or
Person moves to right to achieve the purpose that left and right set is neat.
In the present embodiment, when the left and right neat error of set occurs in the color face image for monitoring to print, according to preset
Reference color face image data determines i.e. each color face to be adjusted image data of its allochromatic colour face image data relative to reference color face image
The left empty adjusted value of data, to indicate each spray head according to corresponding to be adjusted when carrying out the left and right neat error transfer factor of set
Error transfer factor value corresponding to the image data of color face adjusts the left null value of color face to be adjusted image data, so that each spray head root
When being printed according to color face adjusted image data, left and right set is neat.By when monitoring to carry out the neat adjustment of left and right set,
Based on the left empty adjusted value of determination, the online subsequent printing color face image data of real-time perfoming relative to reference color face image data
The neat adjustment of left and right set, fast and easy improves the neat adjustment treatment effeciency of left and right set while guaranteeing print quality.
