Step S4: according to print area actual grid information obtained in step S3 and corresponding theoretical grid information, weight
The new data for calculating real image；
Step S41: according to the printing obtained in the print area theoretical grid information and step S32 obtained in step S31
Region actual grid information calculates print area ink-jet information；There are two types of embodiments for the step:
Mode A: by the way of real-time rip, with print area theoretical grid information to print area actual grid information
Real-time rip is carried out, print area ink-jet information is obtained；
Mode B: using theoretical image is pre-processed, obtaining prn file, is beaten according to the calculating of print area theoretical grid information
Print the ink-jet information of region actual grid；
Preferably, the present invention uses B embodiment；
Step S42: 1pass print data is obtained.
S5: the data of the real image of acquisition are uploaded in the controller of ink-jet apparatus as print data；
Step S6: after the controller 11 of ink-jet apparatus reads in the data of real image, start to print；
Step S7: video camera 68 continues to shoot the image of subsequent region, is recycled with this.
Embodiment two
Referring to Fig.1 0, the difference with embodiment one is, the side of water tank 43 is provided with liquid level sensor 60, with tap
Connection is solenoid valve 66, and liquid level sensor 60 and solenoid valve 66 are electrically connected with the control panel 61 for being set to 43 outside of water tank
It connects.Referring to Fig.1 1, liquid level sensor 60 detects the water level height in water tank 43, one detection signal of output
When the amplitude that it detects signal is less than minimum threshold, enabling signal is exported；It include the first ratio on control panel 61
Compared with device 63, the first comparator 63 include minimum threshold generative circuit 62 and first comparator 63, and liquid level sensor 60 is defeated
Reverse input end of the liquid level signal to first comparator 63 out, the non-inverting input terminal of minimum threshold input first comparator 63, when
When detecting signal less than minimum threshold, the output end output enabling signal of first comparator 63 is to solenoid valve 66 to control solenoid valve
66 unlatching.In addition, exporting brake signal when the amplitude for detecting signal is greater than max-thresholds；Further include on control panel 61
Max-thresholds generative circuit 64 and the second comparator 65, detection signal input the noninverting input of the second comparator 65, maximum threshold
The inverting input terminal of value the second comparator 65 of input, when detecting signal greater than max-thresholds, the output end of the second comparator 65
Output stop signal controls the closing of solenoid valve 66 to solenoid valve 66, to control the water in water tank 43.
Embodiment three
Difference with embodiment one is that the first drying beam 6 is connected to the both ends of the second drying beam 17, and the first drying beam
