Digital Printing Options

HP's liquid electrophotographic printing ink ("HP ElectroInk") can be imaged to create something as small as a 1-micron spot, something that, in turn, gives HP Indigo the ability to print with a level of quality that many feel exceeds flexography.

Inkjet is a substantially different digital imaging method. It involves the ejection of extremely small ink droplets through a printhead directly onto a substrate. There are several different types of inks used in inkjet printing, including water-based inks, solvent-based inks, UV-curable inks and a latex/latex resin ink technology (used mostly in signage and graphics printing) that HP introduced in 2008.
