Vince Cahill, president of VCE
Solutions (Waynesboro, PA), a firm
that consults with Fortune 500 and
other companies, is a recognized ace
on digital print systems and, like me, he
believes readers should understand
the central systems and processes
before making print machine buying
decisions. For example, Cahill separates inkjet components as ink, fluids,
delivery systems, substrates, coatings,
driver boards and software, but emphasizes that printheads are the central
component. Printhead characteristics
and capabilities determine the machine
results - resolution, dot accuracy,
speed, ink chemistry and viscosity.
Regarding MEMS printheads, Cahill
notes that interrelated MEMS manufacturing measures have enabled
manufacturers to increase resolution,
print speed and dot-placement accuracy which brings inkjet printer performance level with analog printing.
Cahill says MEMS manufacturing
processes intimately fabricate different appliances (and tiers) that are
subsequently assembled into inkjet

printheads. The MEMS building
processes allow the production of
densely packed systems - transistors,
sensors and printheads - in submicron
sizes of less than 500 nanometers (nm).
Such packages are generally labeled
as Nano-electro-mechanical systems.
MEMS printheads, by the way, are
appraised in nozzles per inch (npi).
Cahill says MEMS processes produce
inkjet printheads with smaller features,
less weight, greater precision and
lower cost that other printhead manufacturing systems, which clearly
predicts that MEMS printheads, in
present or later amended forms,
stand in the future of every digital
imaging operation.
LARGE-FORMAT MEMS SYSTEMS
Several companies build single-pass
MEMS printheads for installation in
large-format digital print machines.
As noted above, "single-pass" suggests
that the media passes through the
print machine one time, regardless
of the number of inks applied. An
example is Fujifilm Dimatix's Samba
and StarFire silicone-based MEMS
printheads. The Samba features 2,048
individually addressable nozzles,
1,200-dpi native resolution and a
native ink drop size of 2.4 pL that,
the company said, can jet both UVcure and aqueous inks. The singlepass feature arrives via the Samba
scalability technology because its
1.7-in.-wide printheads are easily
gang-arrayed to make a wide-span
print bar. HP Scitex produces the

XL2200 X2, silicone-based MEMS
printhead designed for its HP Scitex
FB7500/FB7600 printers that use
UV-cure ink. HP said its X2 printhead
incorporates silicon-based MEMS
technology that features a combination of HP Scitex's semiconductor
manufacturing and piezoelectric
inkjet technology. These industrial
printheads operate in arrays up to
1,000 sets. HP said the FB7600, equipped with the X2 printheads, produces
images at speeds up to 5,380 sq. ft./hr.
The HP Scitex FB7500 UV-cure flatbed printer, equipped with the X2
printheads, produces high-quality
POP/POS applications, exhibition
graphics, signage, backlit displays and
posters at speeds up to 5,380 sq. ft./hr.
The Xaar 1201 thin film, piezo,
silicon MEMS printheads deliver
eight gray levels at 600 npi to give
an apparent resolution of 1,440 dpi,
and can be configured to print four
colors at 300 npi or one or two colors
at 600 dpi. The speed and color agility
depend on the price point and enduser profile that OEMs wish to target.
The Xaar 1201 can jet dye-sublimation,
eco-solvent, UV-cure or aqueous
inks. The Xaar 5601 thin film piezo
silicon MEMS technology features
5,600 nozzles and can jet up to 8L
of fluid per hour. As noted above,
modern MEMS printheads operate
at speeds of more than 5,000 sq. ft./
hr. - which, just for a comparative
assessment, equals more than 3,500
A4 sheets an hour. Impressed? Get
this; the research is ongoing.
