Apply.
The shower nozzle that the present invention is provided, can slow down each swath fringe region in many 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.
Shower nozzle while inkjet printing is carried out the both sides in swath region spray to be formed liquid atmosphere 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 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 is communicated.
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, be capable of achieving the application purpose, its objective without departing from
Design philosophy of the invention, will not be repeated here, and all should 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 design philosophy of the invention, herein not
Repeat again, all should belong in the protection domain of the application.
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
It is 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.
The inkjet printing methods that the present invention is provided, 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, to realize the swath after the completion of inkjet printing
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, it is consistent with interior zone to ensure the pixel thick and profile that print swath fringe region.
Wherein, the first liquid is the volatile solvent for configuring ink.
The present invention provide continuous inkjet printing method, as shown in Fig. 2 print area include transversely be sequentially arranged and
Continuous N number of swath region, including：
Step 102, the main jet ink passage of shower nozzle carries out ink-jet and beats in first swath region of print area along longitudinal direction
Print, first guide's inkjet channel and second guide's inkjet channel of shower nozzle carry out inkjet printing first both sides in swath region
Form the liquid atmosphere of first liquid；
Step 104, inkjet printing is carried out to opposite side successively, and shower nozzle main jet ink passage at n-th of print area
Inkjet printing is carried out along longitudinal direction in swath region, first guide's inkjet channel near (n-1)th swath area side of shower nozzle is stopped
Only (it is of course also possible to continuing inkjet printing) carries out inkjet printing, shower nozzle away from (n-1)th the second guide of swath area side
Inkjet channel carries out the liquid atmosphere that inkjet printing forms first liquid n-th one side in swath region；
Wherein, N ＞ 1, numerical value is identical when n ＞ 1, N and n take maximum.
After so may insure each swath printing, the sub-pixel in edge is (i.e.：Swath fringe region) all it is formed with
The liquid atmosphere (being located at the periphery of swath fringe region) of first liquid, slows down the solvent rate of volatilization of edge subpixel, and then
Ensure the organic film that edge subpixel is formed dries pattern.
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) be all formed with the solution atmosphere of first liquid, so as to making the rate of drying of swath fringe region during dry
Slow down and consistent with the rate of drying in other regions of swath, improve swath fringe region dries pattern and pixel thickness, makes
Swath fringe region does not have notable difference with the pixel thick and profile in other regions of swath.
Print area includes transversely being sequentially arranged and continuous N number of swath region, and shower nozzle is often printed once, and main jet ink is logical
Road 4 inkjet printing, one swath region, N number of swath region of the shower nozzle in print area transversely prints n times successively, that is, complete N
The inkjet printing in individual swath region.
In sum, the shower nozzle that the present invention is provided, can slow down each swath in many 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.
