According to the present invention, described image processing module includes receiving module 010, hierarchical block 020, the and of computing module 030
Output module 040.
As shown in Figure 6, the receiving module 010 is used to receive image information to be printed, can pass through data wire, indigo plant
Image information to be printed is transferred to receiving module by the transmission modes such as tooth；
The hierarchical block 020 is used to divide the image into multilayer according to the shade degree of image, generally comprises at least
One layer of hypothallus and one layer of color layer, therefore at least need to be divided into two layers, more layers can also be divided the image on this basis,
That is one or more layers hypothallus and one or more layers color layer.The presence of hypothallus causes final image to have stereoeffect,
Hypothallus can select to print one or many, i.e., once print more matrix material and form thicker matrix, or repeatedly printing
Matrix material, ultimately form thicker matrix, color layer finally printed on hypothallus, can also hypothallus replace with color layer beat
Print.It can select to set any number of number of plies in principle, the specific number of plies is according to desired print image readability and printing
Image solid sensing strong or weak unrestricted choice.That is, the number of plies separated is more, 3D effect or third dimension are stronger, print quality
It is higher, accordingly also extend the time-write interval.
In the multiple picture layers separated by hierarchical block, include at least one picture layer with image to be printed
Color information, the information of the picture layer are needed to be passed to computing module, and the picture layer institute is printed to calculate by computing module
The color needed is with when corresponding shower nozzle working condition；In multiple picture layers, also include and recite dark colour region in image
The picture layer of information, the picture layer can have multiple, and the area size recorded on different picture layers can also be different；
Its page order is the picture layer that dark colour area information is recorded in printing first, and only can use white/Transparent color
Material printing, be all that the picture layer for recording dark colour area information then preferentially prints the larger picture layer in region of record, institute
State record dark colour area information picture layer all print after the completion of, already have certain thickness on the workpiece to be printed,
Carry the picture layer of the color information of image to be printed described in printing on this basis again.Above-mentioned print procedure is primarily adapted for use in point
Situation when layer is less, can be during the picture layer for recording dark colour area information be printed if layering is a lot
Appropriate insert band needs the picture layer of the color information of print image, to cause the product photo upper projecting portion point finally printed
Sidepiece color it is uniform, third dimension is enriched.

Lower step：
Step 1, image information is obtained, is handled by image processing module,
Step 2, thing to be printed or workpiece 6 are placed on workbench 4, adjust the distance of thing and shower nozzle to be printed,
Step 3, by the workbench 4 in performs device and the work compound of nozzle component 3, first in workpiece or thing to be printed
Upper printing matrix material, the optional step are carried out once or repeatedly,
Step 4, by the workbench 4 in performs device and the work compound of nozzle component 3, beaten on workpiece or thing to be printed
Printing colorful material, the optional step is carried out once or repeatedly,
Optionally repeat above step 3 and 4, until printing finishes.
In above step 1, image processing module processing mainly includes following step by step 1 ' -3 '：
Step 1 '：Receiving module into image processing module inputs image to be printed；
Step 2 '：The input layering number of plies into hierarchical block,
Step 3 '：After module to be calculated calculates completion and obtained data is transferred into performs device by output module
Start performs device.
In above step 2, thing to be printed or workpiece 6 are placed on workbench 4, on the distance principle of thing and shower nozzle to be printed
It is more near better, but on condition that shower nozzle can not be scraped, therefore, setting infrared ray to survey the height progress that high sensor treats printed matter
Measurement, the distance of general control thing to be printed and shower nozzle 0 between 20mm, preferably 1 to 15mm, more preferably 2 to 10mm, it is also excellent
3 are selected to 5mm.
Above step 3 is to print matrix material on workpiece or thing to be printed, can print it is one or many, depending on required base
Depending on the thickness of matter material；
Above step 4 is to print colorful material on workpiece or thing to be printed, can be that last time prints, that is, print
Colorful material terminates to print；But when needing that print pattern is three-dimensional or 3D effect is more apparent or the thickness of matrix material is thicker,
The colorful material can also be printed repeatedly, so as to avoid patterned side from showing out host material.
Above step 3 and 4 needs to complete by the workbench 4 in performs device and the work compound of nozzle component 3.
Need to check whether the material in performs device is sufficient, and whether equipment state is normal before performs device is started,
And workpiece to be printed is mounted and fixed on workbench before activation；
, it is necessary to nozzle component is moved to above liquid sucking device 5 before performs device performs print job, and to shower nozzle
Jet pipe on component does imbibition processing；
In print procedure, at predetermined time intervals or nozzle component back and forth needs to spray later several times along X-direction
Head assembly is moved to the top of waste collection groove 1, and performs and dissipate spray operation, and in the present invention preferably, nozzle component is past along X-direction
Move 3-15 times again, preferably 5-12 times, performed after more preferably 7-10 times and once dissipate spray operation.
Further, during performs device print image, white/Transparent color matrix material is loaded with first
Nozzles spray material on jet pipe, the jet pipe print the image of white or Transparent color, and the image by spraying material
There is a third dimension, the subregion on image is outwardly, finally has and is loaded with the jet pipe of red, yellow, blueness and black
Nozzles spray material, complete the print job to workpiece to be printed.
Preferably, the region to be printed of workpiece to be printed is white, to strengthen visual effect, if the region to be printed
For non-white, it may be considered that the region is sprayed into white first, in addition, heretofore described white/Transparent color material, excellent
Elect white mass as.
The product printed according to printing equipment provided by the invention and Method of printing is colored, imitated with stereoscopic vision
The image of fruit, the image and the image being delivered in image processing module are basically identical, and difference is that the image is not plane
Figure, it has certain height in the deeper region of color, i.e., the region is protruding upward, enhances the third dimension of image,
Seem more lively, image.
Embodiment 1
