Abstract

A method for improving the printing efficiency of a large-scale UV inkjet printer is characterized in that a color inkjet head and a white inkjet head are placed in a print head module, and a displacement controller is connected to at least one of the inkjet heads. The displacement controller is controlled to cause the inkjet head connected to the displacement controller to shift on the print head module. The two inkjet heads are displaced before printing output. In this way, the UV inkjet printer can achieve good output efficiency regardless of whether it prints color or white first.

Description

Method and device for improving printing efficiency of large-scale UV inkjet printer

technical field

The present invention relates to a method and device for improving printing efficiency of a large-scale UV inkjet printer, in particular to a method of controlling the displacement of a color or white inkjet head so that two inkjet heads form a misalignment and then start printing output. The printing efficiency can be greatly improved by the device and the device, and it is suitable for the application of large-scale UV inkjet printers.

Background technique

In the peripheral equipment of the computer or printing industry, the printer seems to have become one of the necessary basic equipment. In addition to printing documents, jobs and reports, with the advancement of color inkjet technology, inkjet printers can be used Different color ink cartridges spray different concentrations of colors at the same position to produce the desired color. Therefore, it is no longer a dream to use a printer to print out a photo-quality level.

For the printing industry, inkjet products are the trend of the world. For a small number of various products, inkjet printers can be used to print in a timely manner, which saves the time and work of making color separation screens. In this competitive era more advantages.

Please refer to Figure 1. The arrangement of the inkjet heads B in the printing module A of the current large-scale UV inkjet printers is to arrange the color inkjet head B1 and the white inkjet head B2 in parallel. For print C requirements, first print color and then print white background, or print white background first and then print color, it is necessary to control the order of output color or white before output. For example, if you want to output white, due to color printing Ink head B1 and white inkjet head B2 are designed to be arranged flush, so it is necessary to control the color part to not output first, and the white part to output first, and when the white output is completed, then control the white part to not output, and the color part to output , so that when the color inkjet head B1 and the white inkjet head B2 arranged in the same printing module B are working as a whole, the inkjet head B can only achieve half of the inkjet speed and half of the printing effect.

Detailed ways

Please refer to Fig. 2-Fig. 5, the illustrated content is an embodiment of the method for improving the printing efficiency of the large-scale UV inkjet printer of the present invention, which includes the following steps:

a. A displacement controller is connected to at least one of the color inkjet head or the white inkjet head;

b. Control the displacement controller so that the inkjet head connected with the displacement controller is displaced in the print head module, so that the two inkjet heads are dislocated before printing out;

Wherein, the displacement controller 1 is a mechanical or electronic controller, which is controlled by a computer and is mainly used to drive the inkjet head to move. Its structural design can use various existing mechanical or electronic controllers. After the electronic controller (such as driven by a motor, spring or electronic signal induction) is connected to the inkjet head, the purpose of control can be achieved, so the present invention does not describe the structure of the displacement controller 1 in detail.

During implementation, as shown in Figures 3 to 5, when the color inkjet head 2 and the white inkjet head 3 are installed in the print head module 4 of the large-scale UV inkjet printer, the user prints according to the Depending on the need or the print 5, determine whether to output color or white first, and then control the displacement controller 1 through a computer to make the color inkjet head 2 or white inkjet head 3 connected to the displacement controller 1 Displacement, as shown in Figure 4, taking the connection between the displacement controller 1 and the white inkjet head 3 as an example, when printing white first, the displacement controller 1 can control the white inkjet head 3 on the print head module 4 forward displacement, so that the white inkjet head 3 and the color inkjet head 2 form a dislocation, thereby, when printing starts, the white color can be printed first, and then the color can be printed.

Similarly, as shown in Figure 5, when the color is to be printed first, the displacement controller 1 can control the white inkjet head 3 to move backward in the print head module 4, so that the white inkjet head 3 and the color inkjet head The head 2 forms a dislocation, thereby, when printing starts, the color inkjet head 2 can print first, and then print white.

In addition, as shown in Figures 6 to 8, the present invention can also connect the color inkjet head 2 and the white inkjet head 3 to the above-mentioned displacement controller 1, so that when the displacement controller 1 is activated, the color inkjet head 2 and the white inkjet head 3 can be displaced separately, such as when printing white first, the white inkjet head 3 is displaced forward (as shown in Figure 7), and when printing color first, the color inkjet head 2 is displaced forward (as shown in Figure 7). 8), make the two inkjet heads form a dislocation and then print out, even the color inkjet head 2 and the white inkjet head 3 can be displaced at the same time by a distance in the opposite direction (not shown), so that the two inkjet heads Printing after the heads 2 and 3 are dislocated can also achieve the effect of increasing the printing speed and greatly increase the range of the printout.

Therefore, the present invention can be placed in the print head module 4 of a large-scale UV inkjet printer for the color inkjet head 2 and the white inkjet head 3, and the color inkjet head 2 and the white inkjet head 3 Can be displaced in the print head module 4, so that one of the inkjet heads 2 or 3 can be displaced in the print head module 4 under the control of the displacement controller 1, and form a misalignment with the other inkjet head 2 or 3 Then print out, so that the UV inkjet printer can achieve good output efficiency whether it prints color or white first.

The above description is only used to reveal the practicable forms of the present invention, and should not be used to limit the scope of the present invention. All changes and modifications that can be obviously made by those skilled in the art should be regarded as not departing from the essence of the present invention. .
