Thermal foaming technology is one of the most successful inkjet technologies on the market. In addition to Canon being used by several major manufacturers, HP has also adopted this technology, but the thermal foaming methods of the two are still somewhat different.
Side-shooter
Roof-shooter
As we can see in the figure above, thermal foam inkjet technology can be divided into two types: roof-shooter and side-shooter according to their different forms. The heating element located above the nozzle emits, while the side-emission heating element is located next to the nozzle. Canon mainly uses side-shooter side-emission technology, while HP mainly uses roof-shooter top-emission thermal foam inkjet technology.
HP Top Launch Thermal Foam Technology
How HP top-launch thermal foaming technology works
Don't underestimate the simple changes in the position of the heating element. Compared with the side-emission technology, the heating element with the top-emission technology is closer to the nozzle position, so the ink droplets ejected by the steam bubble pressure have a shorter stroke, and the volume is smaller. It can be ejected onto the printing medium in a shorter time. In addition, more ink storage at the back end of the steam bubble also helps the steam bubble to condense faster. The deterioration of the simple position brings faster ejection speed and smaller ink droplet volume, which makes the HP printer greatly improve the printing precision and the printing speed.
Today, HP's patented Thermal InkJet technology has been widely used in many industrial printing fields, such as ticket printing, label printing, postal services, QR code postage printing, security printing and packaging inkjet printing, etc. , Its efficient printing speed and excellent print quality provide partners with more innovative value.
