In the coding process, the inkjet printer generally uses a conveying device to make the object to be printed and the object to be printed have a relative displacement. The inkjet printer uses the ink dots of the inkjet printer to perform dot-like printing. These dot-like inks are composed of Our common alphanumerics and so on. When the inkjet printer is printing, the object to be printed passes through the lower end of the inkjet printer at a constant speed, and the inkjet printer evenly arranges dots on the inkjet object. Therefore, in this way, the marks produced by the inkjet printer are all linear, which is similar to the generation of line segments. Compared with some flat and flat objects, the traditional coding method is quite simple for small character inkjet printers, large character inkjet printers, and high resolution inkjet printers. You can also use conveyors, paging machines, etc. Products improve coding efficiency! Save labor costs. But for some irregular objects, concave and convex objects such as lamps, it is necessary to use the coding rotation supporting equipment to achieve fast and efficient coding! Example description Generally, building materials lamps and lanterns need to install rotating equipment when using inkjet printers to print. Only in this way can we achieve a perfect identification solution. Relatively in the same plane, in fact, requires a relatively flat surface of the object. Irregular objects, such as circles and pillars, need to use an external device to make the printing object rotate and print, and keep the distance between the object and the printer relatively consistent. Therefore, when printing circular pillars, a rotating device is indispensable. Only under such conditions can it be ensured that the logo printed on it will not be deformed or shifted.
