Method for producing stereo image by using UV digital inkjet method

The invention relates to a method for producing a stereoscopic image, in particular to a method for producing a stereoscopic image by using a UV digital inkjet method.

The existing inkjet method for producing a stereoscopic image, which uses a UV-curable ink, can produce a three-dimensional effect by stacking the ink. Specifically, the prior art uses an inkjet machine, and the inkjet machine has a The white ink inkjet group and the one color inkjet painting group, the white ink inkjet group is located in front of the color inkjet printing group, each inkjet group includes a plurality of nozzles, and the inkjet printing area of the two inkjet printing groups has the same length of front and rear; the white inkjet printing group uses the aforementioned UV curing ink. .

The entire inkjet program is divided into two steps: white ink stacking and color ink coloring.

When the white ink is stacked, first, the inkjet device is laterally moved to the other side on the object, and the white inkjet group simultaneously ejects onto the target; then the inkjet device moves forward, and the moving distance and the inkjet group are printed. The front and rear lengths of the area are equal; then the ink jet machine moves laterally to the starting side and simultaneously ejects ink; then the ink jet machine moves forward again, and the moving distance is the same as last time; this cycle is repeated until the ink jet machine moves forward After the target; then, the inkjet machine returns to the starting position and realigns, and then repeats the above actions several times until only the last white ink is left to complete the undulation of the surface.

Then, the color ink is colored. At this time, the inkjet machine returns to the starting position and realigns, and then follows the same path to start moving; when the inkjet machine moves, the white inkjet group completes the last white inkjet printing and completes the drawing. The high and low undulations, while the inkjet printing group located behind the white inkjet group is simultaneously inkjet in the previous horizontal interval (the interval has been completed by the white inkjet group in the previous lateral movement), and the interval is completed. Coloring. The color inkjet printing group completes the coloring of the last horizontal section, that is, completes the inkjet printing process.

In the color ink coloring process, when the first horizontal movement is performed, the inkjet printing group does not overlap with the target because its inkjet area has not overlapped with the target object, and in the last lateral movement, the white inkjet printing group has a printing area because of its inkjet printing area. The target has been left, so the same is not inkjet.

However, this prior art has the following disadvantages:

First, since the prior art requires the inkjet machine to repeatedly travel through the same route several times to repeatedly stack the white ink and the inkjet ink, it takes time.

Second, when the inkjet machine returns to the starting position each time, it must be realigned, and the alignment is prone to errors, which leads to poor results.

Third, the height fluctuation of the target depends on the number of repeated ink ejections of the white inkjet group, and the number of repeated ink ejections of the white ink depends on the number of times the inkjet device moves back from the starting position, so the difference in the depth of the target is larger. Then, the more the inkjet machine returns to the starting position, the more times it is re-moved, resulting in longer working hours.

In view of the existing shortcomings and disadvantages of the inkjet stereoscopic image, the present invention provides a method for fabricating a stereo image by using a UV digital inkjet method, which is shorter in operation time than the prior art, and Must be realigned.

In order to achieve the above object, the technical means adopted by the present invention is to design a method for fabricating a stereo image by using a UV digital inkjet method, comprising: preparing a step of selecting an inkjet device and a target located under the inkjet device.

In the present embodiment, there are eight nozzles 11, wherein the two nozzles 11 on the rightmost side use white ink, and the other nozzles 11 use colored ink, and the right-to-left order is Lm (Light magenta, light Magenta), Lc (Light cyan), Y (Yellow, Yellow), M (Magenta, Magenta), C (Cyan, Cyan), K (Black, Black).

Referring to FIG. 2, the inkjet device 10 is located on the upper side of the target object 50, and the area to be printed on the target object 50 is divided into sections by computer program control, and each section is sequentially from front to back. The interval 51, the second section 52, ..., etc., the front and rear distances of each section are equal to the front and rear lengths of the inkjet areas of the respective inkjet groups 12, 13, and the white inkjet group 12 is aligned with the first section 51 of the object 50; In the present embodiment, the target 50 is divided into eight sections, which are sequentially the first section 51 to the eighth section 58.

Stereotactic step: Referring to FIG. 2 and FIG. 5, the inkjet device 10 is moved back and forth laterally between the two sides of the object 50, wherein it is recorded once from the side of the object 50 to the other side; During the process, the white inkjet group 12 simultaneously ejects ink into the first section 51 of the target 50 and completes the high and low fluctuations required for the section 51.

Step of shifting: Referring to FIG. 3 and FIG. 6, the inkjet device 10 advances by an interval, at which time the white inkjet group 12 is aligned with the second section 52 of the target 50, and the inkjet printing group 13 and the target 50 are The first section 51 is aligned back and forth.

At this time, since the inkjet printing area of the inkjet printing group 13 starts to overlap with the area to be printed on the object 50, it is then changed to:

Coloring and three-dimensional steps: the inkjet machine 10 is moved back and forth laterally between the two sides of the object 50, wherein it is recorded once from the side of the object 50 to the other side; during the movement, the white inkjet group 12 Inkjet ink is sprayed on the second section 52 of the target 50, and the inkjet printing group 13 is inkjetted in the first section 51 of the target 50; the white inkjet group 12 completes the high and low fluctuations required by the second section 52, and the inkjet printing group 13 then completes the coloring process of the first section 51, and the inkjet of the first section 51 is also completed here.

Step of shifting: Referring to FIG. 4 and FIG. 7, the inkjet machine 10 advances by an interval, at which time the white inkjet group 12 is aligned with the third section 53 of the target 50, and the inkjet printing group 13 and the target 50 are The second section 52 is aligned back and forth.

Coloring and three-dimensional steps: the inkjet machine 10 is moved back and forth laterally between the two sides of the object 50, wherein it is recorded once from the side of the object 50 to the other side; during the movement, the white inkjet group 12 In the third section 53 of the target object 50, the inkjet printing group 13 is inkjetted in the second section 52 of the target 50; the white inkjet group 12 forms the high and low fluctuations required for the third section 53, and the inkjet printing group 13 then completes the coloring process of the second section 52, and the inkjet of the second section 52 is also completed here.

Referring to FIG. 1 , the coloring and stereoscopic steps and the shifting step are repeated as described above until the inkjet printing area of the white inkjet printing group 12 does not overlap with the area to be printed on the target, that is, when the inkjet device 10 is oriented. Before moving, after the white inkjet printing group 12 moves to the eighth interval of the target object, and the color inkjet printing group 13 is aligned with the eighth interval of the target object, it is then changed to:

Coloring step: the inkjet device 10 is moved back and forth laterally between the two sides of the object, wherein the movement from the side of the object to the other side is recorded once; during the movement, the white inkjet group 12 stops moving, the color ink The inkjet group 13 is inkjet in the eighth section of the target, and completes the coloring process of the eighth section, and the inkjet of the eighth section is also completed here. The inkjet program for the target is also completed.

In the coloring and three-dimensional steps, and in the coloring step, each time the inkjet machine 10 moves laterally, the inkjet printing set 13 will eject ink, and the amount of ink discharged per time is evenly distributed by computer control. Further, after the inkjet printing group 13 is repeatedly inked back and forth in the same lateral section, the horizontal section can obtain the desired color without being excessively colored. However, in other embodiments, the inkjet printing group can also eject ink only when the last lateral movement, and the required color ink is sprayed at one time; that is, in the coloring step, the inkjet machine can also be in each The interval is only moved laterally once, and the movement causes the inkjet printing group to spray the desired color ink once.

While the nozzles 110 are ejecting ink, the ink jets are also irradiated with a machine such as a UV lamp to cure the inks. However, this is a familiar part of the art, and therefore will not be described here.

Further, in any step, when the inkjet device 10 is laterally moved between the both sides of the object, it is recorded once from the object side to the other side, so when the number of repeated movements is an even number of times, the ink is ejected. The implement 10 will perform the shifting step on the starting side, and if it is an odd number of times, the ink jetting implement 10 will perform the shifting step on the other side.

When the invention is used, the inkjet device 10 can be moved forward by continuously moving back and forth on the object, so that the inkjet printing group 12 can continuously eject ink in the same lateral interval to stack the required height. The undulations, in turn, allow the inkjet machine 10 to complete all the printing processes after completing one path, and thereby achieve the following effects: First, by performing all the printing processes at one time, the spray must be made compared to the prior art. The ink machine 10 repeatedly travels through the same route several times, which can save man-hours. Secondly, the problem of repeating the alignment is eliminated by eliminating the need to return the inkjet device 10 to the starting position and then moving again. Third, the present invention The inkjet device 10 can be continuously moved back and forth on the object so that the height fluctuations depend on the number of times the inkjet device 10 moves back and forth in the lateral region. The fluctuations of the prior art are dependent on the inkjet device 10 from The starting position re-starts the number of moves, which can further save time and increase efficiency.

The invention thus achieves a shorter working time than the prior art and does not require realignment.

The invention controls the number of ink ejections by continuously moving the inkjet machine 10 horizontally back and forth on the target object, so as to quickly inject the deep and shallow more obvious fluctuations, and the color ink without realignment can be used to make the target The object accurately displays the simulated texture of the wood chip or the oil-like three-dimensional embossing and the like.

In other embodiments, each of the nozzles may not be divided into front and rear ink blocks, but all the nozzles on each nozzle are ink-jetted, and only the white ink nozzles may be directly disposed before the color ink nozzles.

In other embodiments, the front and rear lengths of the inkjet printing area of the white inkjet printing group and the color inkjet printing group may not be equal. For example, the front and back lengths of the inkjet printing area of the white inkjet printing group and the color inkjet printing group may be three to one. At this time, it is assumed that in the shifting step, each time the inkjet machine advances by the same length as the front and back of the inkjet printing group, any lateral region on the target will experience three times of the white inkjet group thereon. The horizontal movement back and forth (three times are the front and rear three equal parts of the white inkjet printing group), and each white inkjet printing group can also move back and forth a plurality of times in the lateral direction when moving horizontally back and forth, thereby further strengthening the height fluctuation.

In other embodiments, in the shifting step, the distance traveled by the inkjet machine may be less than the length of the front and back of the inkjet printing area of the two inkjet groups, and any horizontal region on the target may undergo a plurality of white inkjet printing groups. And the color inkjet printing group moves back and forth in the horizontal direction (each time is a different part of the front and back of the white inkjet printing group and the color inkjet printing group), and each white inkjet printing group can also move back and forth laterally when moving horizontally back and forth Move multiple times, which can further enhance the height fluctuations; while the inkjet printing set can be set by the computer to average the amount of inkjet each time, or only when the last lateral movement is required Colorful ink.

In other embodiments, when the inkjet device advances through a section with respect to the target, it may not advance for the inkjet implement, but may retreat for the target.

The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the invention, and A person skilled in the art can make some modifications or modifications to equivalent embodiments by using the above-disclosed technical contents without departing from the technical scope of the present invention.
