Ultra Hi-Definition Prints Technical Brief Page 7
The ABCDEF’s of Ultra Hi-Definition Prints—DX5 Technology
Epson Ultra Hi-Definition printers use Epson’s
patented MicroPiezo® print head with DX5
technology that delivers five sizes of ink
droplets as small as 1.5 picoliters.
Because printed “dots” are comprised of
a number of ink droplets, DX5 technology
allows Epson Ultra Hi-Definition printers to
produce a greater combination of ink droplets,
resulting in:
• Smoother gradations
• Grain-free prints
• More color combinations
• Sharper detail
Epson MicroPiezo print head technology also has these advantages over competitors who use thermal
technology:
Epson MicroPiezo Technology Competitors Thermal Technology
“Smart” nozzles
One nozzle can produce multiple ink droplet sizes
“Static” nozzles
One nozzle can only produce one size ink droplet
“Fast” nozzles
Higher firing frequencies
“Slow” nozzles
Lower firing rates
Bottom Line:
Only Epson offers state-of-the-art technology
(5 ink droplet sizes per nozzle)
Bottom Line:
Competitors have more nozzles because they need
more nozzles. They need multiple print heads or print
heads with different nozzle sizes to produce multiple
ink droplet sizes
With an intelligent nozzle design and ink color selection system, Epson Ultra Hi-Definition printers deliver an
unprecedented five sizes of ink droplets with fewer nozzles on the print head—and still produce blazing speed.
Competitive printers can’t come close to the ink droplet combinations available with DX5 technology.
DX5 technology allows Epson Ultra Hi-Definition printers to produce high print quality without sacrificing print
speed:
Did you know? It’s easy to remember what DX5 stands for: Droplets x 5.
Variable sizes and colors combine to
achieve more tone representations
for smoother gradations
Large droplets are used in
dense coverage areas allowing
faster print speeds
Smallest ink droplets produce smooth photos, especially
beneficial for highlights and detailed areas
