Piezoelectric Print Heads Vs. Thermal Print Heads
For professionals and consumers alike, inkjet printing technologies have made producing full color high quality photographs, documents, and fine art reproductions easier, cleaner, and more affordable.
Today, there are two primary types of inkjet print head technologies in use: Piezo (Epson Printers) and Thermal (Canon and HP Printers). In this blog we will be exploring the main difference between the two, as well as some advantages and disadvantages of both.
How does Epson’s Micro Piezo print head work?
In the Epson Micro Piezo print head, microscopic piezoelectric elements (like crystals and ceramics) are built behind the print nozzles. When an electrical charge is applied to them, these elements bend backward, forcing precise amounts of ink onto the substrate (see Diagram 1). Because electrical charges can be turned on and off like a switch, there is a vast amount of control over the rate of ink being ejected through the nozzle while also creating perfectly spherical dots at different droplet sizes.
