In ink droplet image.
Wherein, using the camera system in ink droplet titrimetry system, since print head any spray head, according to any
Acquisition order acquires ink droplet image of the ink droplet of each spray head ejection on print head in dropping process, it should be noted that ink droplet
In image include ink droplet different location in dropping process ink droplet figure (i.e. the shape of ink droplet), shooting be ink droplet whereabouts
Process.
Preferably, camera system successively acquires the ink droplet that each spray head sprays one by one and is falling since one end of print head
Ink droplet image in the process.
Optionally, ink droplet is ejected along certain angle, and (figure is watched from print head front, camera as shown in Figure 2
One in front and one in back with light source, the two sides of print head are separately positioned on, for shooting the ink droplet image of ink droplet), a set of camera shooting can be used

It is rapid to obtain.
Poor is asked to maximum droplet volume and minimum droplet volume, obtains the droplet volume measures of dispersion of some ink droplet；
The droplet volume measures of dispersion of each ink droplet is verified whether in preset threshold (0.5pl), and it is poor to be recorded in droplet volume
Number of ink droplets of the different amount in preset threshold, and quantity reach preset condition (when spray head number be 128, preset condition 115
It is a) it is a when, confirmation ink droplet situation correction result meets the control condition that print head carries out inkjet printing, i.e. print head starts to carry out
Inkjet printing.
Print head ink droplet situation of the present invention corrects each embodiment of result detection method, is utilizing ink droplet titrimetry system pair
After the ink droplet that print head sprays completes the correction of ink droplet situation, since print head current location, successively acquire every on print head
A spray head sprays ink droplet image of the ink droplet in dropping process, obtains each spray head ejection ink droplet according to ink droplet image and was falling
The droplet volume of different location in journey, respectively obtains the maximum droplet volume and minimum droplet volume of each ink droplet, and asks maximum
The difference of droplet volume and minimum droplet volume, obtains the droplet volume measures of dispersion of ink droplet, judges the ink droplet within preset threshold
The number of ink droplets of volume difference amount, when number of ink droplets reaches preset condition, confirmation ink droplet situation correction result is good, and control is beaten
It prints head and carries out inkjet printing, detected so that the present invention can correct result to ink droplet situation, avoid titrating because of ink droplet
Analysis system influences print head spray in error unstable to ink droplet progress ink droplet situation timing and causing correction result to occur
The quality of ink printing.
In one embodiment, as shown in figure 4, the ink droplet sprayed using a set of camera system to each spray head on print head
