introduction:“Inkjet coding"It refers to many related technologies,We use these techniques to make very tiny drops of ink squirt out of the nozzle,Ink drips through the air,Finally, it falls on the surface of the printed object to form a print pattern. Valve printing This method is the easiest to implement,In the past20The middle of the year,It is mainly used for printing on external packing boxes. By and large,A valve printing device includes a low pressure ink system,One electronically controlled case and one with a flexible catheter
