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 Continue reading Piezoelectric Print Heads Vs.

Matte Black vs. Photo Black

Most modern pigment inkjet printers use both a photo black ink and a matte black ink (not simultaneously though). In trying to develop a darker black ink for uncoated papers (cotton fine art, watercolor papers and other matte uncoated papers) the manufacturers were unable to get the ink to dry on coated papers, so they had to resort to two inks. Standard black, usually referred to as photo black, for glossy, semigloss, satin, semimatte, and luster papers, and matte black, which prints darker on the uncoated fine art papers but doesn’t dry on the coated papers.

Customers often ask if they need to use Matte Black ink with a certain paper. There are several ways to find out.
