Apply.
Nozzle provided by the invention, can slow down each swath fringe region in more swath print procedures in use
Rate of drying, makes it consistent with the rate of drying of interior zone, to ensure the pixel thick of each printing swath fringe region
And profile is consistent with interior zone.
Nozzle sprayed while inkjet printing is carried out in the both sides in swath region to be formed liquid atmosphere the first liquid (by
Guide's inkjet channel of both sides sprays), to realize the liquid atmosphere in swath region and swath region two after the completion of inkjet printing
Other liquid atmosphere is consistent (i.e.：Empty regions coat the liquid atmosphere of the first liquid).
In one embodiment of the present of invention, guide's ink entrance includes first guide's ink entrance 11 and second guide
Ink entrance 12, the first guide ink entrance 11 and the second guide ink entrance 12 are located at the both sides of the main ink entrance 2, and
The first guide inkjet channel 31 is communicated with the first guide ink entrance 11, the second guide inkjet channel 32 with it is described
Second guide's ink entrance 12 communicates.
Specifically, the first guide ink entrance 11 and the second guide ink entrance 12 are separate；It is of course also possible to
That first guide's ink entrance 11 is connected with second guide's ink entrance 12, can be achieved the application purpose, its objective without departing from
The design philosophy of the present invention, details are not described herein, should all belong in the protection domain of the application.
Certainly, guide's ink entrance can also set one, first guide's inkjet channel 31 and second guide's inkjet channel 32
Communicated with guide's ink entrance, can also realize the purpose of the application, its objective without departing from the present invention design philosophy, herein not
Repeat, should all belong in the protection domain of the application again.
Further, the main jet ink passage 4 includes the multiple main jet Mo-tse passages being transversely sequentially arranged；Described first
Guide's inkjet channel 31 includes the multiple first guide ink-jet subchannels being transversely sequentially arranged, and multiple first guide sprays
The mouth of Mo-tse passage is gradually reduced radially adjacent to the side of the main jet ink passage 4 so that first away from main jet ink passage 4 is first
The droplet size for leading inkjet channel 31 (nozzle) ejection gradually increases, to ensure the rate of volatilization phase one of swath region each position
Cause；The second guide inkjet channel 32 includes the multiple second guide ink-jet subchannels being transversely sequentially arranged, and multiple institutes
The mouth for stating second guide's ink-jet subchannel is gradually reduced radially adjacent to the side of the main jet ink passage 4 so that away from main jet ink
The droplet size that second guide's inkjet channel 32 (nozzle) of passage 4 sprays gradually increases, to ensure swath region each position
Rate of volatilization it is consistent.
Preferably, the first guide inkjet channel 31, the main jet ink passage 4 and the second guide inkjet channel 32
For jet orifice and/or ink-jet groove.
Preferably, the first guide inkjet channel 31, the main jet ink passage 4 and the second guide inkjet channel 32
It is located along the same line.
Inkjet printing methods provided by the invention, in swath region while inkjet printing or before inkjet printing
(i.e.：One swath region) both sides spray the first liquid to form liquid atmosphere, with realize after the completion of inkjet printing swath
Region is (i.e.：Said one swath region) liquid atmosphere and swath region (i.e.：Said one swath region) both sides liquid
Atmosphere is consistent.
The rate of drying of printing swath fringe region can be slowed down in inkjet printing, make its rate of drying with interior zone
It is consistent, to ensure that the pixel thick of printing swath fringe region and profile are consistent with interior zone.
Wherein, first liquid is the volatile solvent of configuration ink.
The method of continuous inkjet provided by the invention printing, as shown in Fig. 2, print area include transversely being sequentially arranged and
Continuous N number of swath region, including：
Step 102, the main jet ink passage of nozzle is beaten in first swath region of print area along longitudinal direction progress ink-jet
Print, the first guide's inkjet channel and second guide's inkjet channel of nozzle carry out inkjet printing in the both sides in first swath region
Form the liquid atmosphere of the first liquid；
Step 104, inkjet printing is carried out successively to opposite side, and the main jet ink passage of nozzle is at n-th of print area
Inkjet printing is carried out along longitudinal direction in swath region, first guide's inkjet channel close to (n-1)th swath area side of nozzle is stopped
Only (it is of course also possible to continuing inkjet printing) carries out inkjet printing, the second guide away from (n-1)th swath area side of nozzle
Inkjet channel carries out the liquid atmosphere that inkjet printing forms the first liquid in the one side in n-th of swath region；
Wherein, N ＞ 1, n ＞ 1, numerical value is identical when N is maximized with n.
After so may insure each swath printing, the sub-pixel in edge is (i.e.：Swath fringe region) all formed with
The liquid atmosphere (periphery for being located at swath fringe region) of first liquid, slows down the solvent rate of volatilization of edge subpixel, and then
Ensure the drying pattern for the organic film that edge subpixel is formed.
In printing, first guide's inkjet channel, second guide's inkjet channel spray the first solvent, the spraying of main jet ink passage
Ink.In multiple printing technology, by controlling the break-make of guide's inkjet channel, make each swath fringe region (swath region
Periphery) all solution atmosphere formed with the first liquid, so as to make the rate of drying of swath fringe region during drying
Slow down and, the drying pattern and pixel thickness of improvement swath fringe region consistent with the rate of drying in other regions of swath, make
Swath fringe region and the pixel thick and profile in other regions of swath do not have notable difference.
Print area includes transversely being sequentially arranged and continuous N number of swath region, nozzle often print once, and main jet ink is logical
Road 4 inkjet printing, one swath region, N number of swath region of the nozzle in print area transversely print n times, that is, complete N successively
The inkjet printing in a swath region.
In conclusion nozzle provided by the invention, can slow down each swath in more swath print procedures in use
The rate of drying of fringe region, makes it consistent with the rate of drying of interior zone, to ensure each printing swath fringe region
Pixel thick and profile it is consistent with interior zone.
