Processing technology and device of surface ink jet printing

Abstract

The invention discloses a processing technology and a device of surface ink jet printing, used for realizing printing of complex curved surfaces. The technology comprises the following steps: controlling the motion track of the printing spray nozzle according to the curved surface characteristic information of the surface of the object to be processed; and in the motion process of the printing spray nozzle, spraying the printing ink on the surface of the object to be processed through the printing spray nozzle.

Description

technical field [0001] The invention relates to the field of printing technology, in particular to a surface inkjet printing process and device. Background technique [0002] At present, the printing process of applying the raw material pattern to the processed object usually adopts screen printing. The screen printing process includes: screen stretching, plate making, film making, plate printing, and printing. Specifically: according to the printed pattern , to make a printing stencil out of a mesh material, with selected areas of the stencil blocked by print medium absorbent material. Then, the printing medium is injected by applying the printing medium on the front side of the screen and forcing the medium into the mesh of the screen in the non-blocking area, so as to form a uniform thickness ink layer penetrating the screen, forming a non-blocking with the screen The pattern that matches the area. When the side of the screen with the pattern layer of the printing mediu...

Problems solved by technology

[0003] However, this kind of screen printing can generally only be printed on flat or simple curved surfaces, and it is necessary to prepare special equipment for each type or color of printing media, providing fixed-setting equipment, for example: three colors need to be printed When printing patterns, it is necessary to prepare a separate printing screen for each color

It can be seen that the current printing process is quite complicated, and it takes a lot of time, and its production cost is also relatively expensive.

At the same time, it is not possible to achieve good printing effects on complex curved surfaces, such as curved surfaces with structures such as protrusions and depressions.
