HP Electroink is a unique liquid ink (Liquid EP) that combines the advantages of electronic printing with the qualities of liquid ink. HP Electroink contains charged pigmented particles in a liquid carrier.
Like other digital printing technologies, i.e., Dry EP (or Xerography), HP Electroink enables digital printing by electrically controlling the location of the print particles. However, unlike Dry EP, HP ElectroInk enables very small particle size, down to 1-2 microns. HP ElectroInk is supplied as a concentrated paste that is loaded into the press in tubular cartridges in a ‘clean hands’ operation. Inside the press it is fed into ink supply tanks and diluted with oil, to form a fluid mixture of carrier liquid and colorant particles ready for printing.
