As we know, whether daily necessities or industrial supplies all have their own logo, model, QR code, bar code anti-counterfeiting mark. So how are these marks printed? Some manufacturers say they are labeled with laser marking machines, and some manufacturers say they are printed with inkjet printers. So, what is the difference between a laser marking machine and an inkjet printer?

Laser marking machines use laser beams to permanently mark on a variety of different materials. The effect of the marking is to expose the deep material by evaporation of the surface material, thereby engraving beautiful patterns, trademarks and characters. Laser marking machines are mainly divided into ultraviolet laser marking machines, fiber laser marking machines and carbon dioxide laser marking machines. They are engraved with a variety of non-metallic materials, mainly used in clothing accessories, pharmaceutical packaging, alcohol packaging, architectural ceramics, beverage packaging, fabric cutting, rubber products, shell nameplates, craft gifts, electronic components, leather and other industries.

Inkjet printers use ink electrical deflection to deflect the ink dots from the normal flight path and to the surface of the work object. The position of each ink drop is controlled by the amount of charge loaded into the ink droplets. Usually, the ink drops are only in the vertical direction. Changes must be made relative to the prints and nozzles to form the information we want to print. Inkjet printers are mainly concentrated in the beverage, beer, mineral water and other industries.

Compared with inkjet printers, laser marking machines have the advantages of fast marking speed and wide application range. It permanently marks high quality on the surface of various materials and has no force on the surface of the workpiece. It does not cause deformation, the surface of the material will not corrode.

The laser marking machine developed by Perfect Laser uses a fiber laser to produce laser light, and the marking function is realized by a high-speed scanning galvanometer system. The laser is controlled by the industrial computer without contact, the beam quality is good, the laser marking is beautiful and permanent. The machine is small in size and long in service life. It is maintenance free. Therefore, the production cost is low.
