Embodiment Construction
[0017] The present invention will be further described below through embodiments in conjunction with the accompanying drawings.
[0018] like figure 1 As shown, the nozzle device on the UV large-format image printing equipment provided in this embodiment includes a working platform 1, on which a substrate 2 is laid flat, and a guide rail 3 is provided on the working platform 1, and the guide rail 3 There is a print head ink cart 4 that moves along the guide rail 3, and the moving direction of the substrate 2 is perpendicular to the moving direction of the print head ink cart 4. The input side of the substrate, another group of nozzles is located on the output side of the substrate, the two groups of nozzles are divided into different colors of ink, each group of nozzles is connected with a control system, the control system is used to control the speed, time, and time of the nozzles. Ink volume, location. Both ends of the substrate 2 are connected with rotating shafts, which...

The invention discloses a nozzle device on a UV large format image printing device and a printing method. A working platform is comprised. A substrate is tiled on the platform. A guide rail is arranged on the working platform. A nozzle ink vehicle which moves along the guide rail is arranged on the guide rail. The moving direction of the substrate is perpendicular to the moving direction of the nozzle ink vehicle. Two groups of nozzles are arranged in the nozzle ink vehicle. A group of nozzle is located on the input side of the substrate. The other group of nozzle is located on the output side of the substrate. Inks of different colors are respectively arranged in two groups of nozzles. Each group of nozzle is connected with a control system which controls the speed, the time, the ejection amount and the location of the nozzles. The nozzle device has the advantages that the printing manner of coherent white primer and color inkjet on the substrate is realized; the process of alignment is eliminated; the production efficiency is improved; and the yield is greatly improved.
Description
technical field [0001] The invention relates to the technical field of printing, in particular to a nozzle device and a printing method on a UV large-format image printing device. Background technique [0002] At present, the white and color nozzles of this type of printing equipment are all placed in the same horizontal ink cart, regardless of the front and rear, and there is no simultaneous color separation to control printing. In application, when printing a color pattern with white on a substrate that does not absorb ink, the pattern can be completed at one time; when printing a color pattern with white on a substrate that is easy to absorb ink, it is difficult to print the original pattern. The color effect can only be achieved by printing a white background first and then printing in color. That is to say, in order to complete the perfect performance of a pattern, at least two printings are required (sometimes the white background may be printed twice), and at the sam...
