Analysis of the application of coding technology

The application of inkjet marking technology is gradually going deep into every corner, from heavy machinery to as small as a wire, all of which are inseparable from product marking. This technology is also widely used in plastic packaging containers, plastic films, plastic pipes, wires and cables, plastic parts and other products. At present, the types of inkjet printing technology mainly include inkjet printing technology and laser inkjet printing technology.

Inkjet printing technology is also called non-contact printing. Depending on the working principle of the inkjet printer, It can be divided into

continuous jet inkjet printer and on-demand ink jet printer. Continuous jet cij printer is called CIJ type for short, it is

The ink is continuously ejected from a single nozzle through pressure, and the crystal oscillates and breaks to form ink dots; ink

p>

The dots are charged and deflected by high voltage and scanned into characters on the surface of the moving object. Most industrial inkjet systems use CIJ technology, and its speed can reach 1,000 feet per minute, which is much faster than cij printers on demand.

But the image quality is also lower than that of the latter technique. Manufacturers such as cij printers are leaders in this field. The ink-on-demand cij printer is called DOD type for short. The nozzle of the ink supply system is composed of multiple high-precision valves. When printing, the corresponding valve of the font is fast

Open and close, the ink is ejected by the constant internal pressure, forming characters or graphics on the moving surface. A digital signal produces a drop of ink on paper, not a stream of ink

It can produce an effect close to photographic quality. The printing speed of DOD is between 100 feet to 300 feet per minute. Many companies are currently developing high-speed DOD printing equipment that can be used for packaging.

Compared with ink printing technology, laser printing technology is a more advanced

Technology. This technique mainly uses burning and etching to achieve coding. Burning, that is, the laser emits enough energy to remove the ink on the surface of the plastic material, such as the surface of the printed package. Etching, that is, use appropriate laser energy to partially melt the surface of the plastic material to form a groove. After focusing

The ultra-fine laser light speed is like a knife, which can remove the surface material of the object point by point without generating any damage.

Mechanical extrusion or mechanical stress, so the processed items will not be damaged. In addition to the general information marking function

, the anti-counterfeiting function of laser coding technology is more significant. The application of laser coding technology in the Chinese market has just begun, but because of its high reliability, low operating cost, safety

easy installation and operation and precise barcode printing characteristics , Will win a broader market in the future.

At present, the development of China's sign industry is in the ascendant, with a very high growth rate. At the same time, the market's requirements for sign technology are also changing. The reliability and stability of cij printer equipment will be an important trend in future technology development.
