Speed and power are two important aspects of the vehicles we depend on. Every-
body loves the feeling of speeding around in a sports car, but it’s the efcient power
of trucks, trains and ships that move the world’s goods to market. Both the speedy
sports car and the high-capacity truck serve a purpose in the world; the choice de

PrecisionCore printhead technology serves as a platform that can deliver both the
speed and power that are the ultimate drivers of economic output in the world of
printing. The PrecisionCore printheads have two to three times the resolution of
Epson’s conventional piezo printheads. They can be fast and powerful at the same
time, with the ability both to re quickly and deliver multiple drop volumes on de

mand. For pure speed, consider Epson’s large-format printers whose moving Pre-
cisionCore piezo elements each re nearly 50,000 times per second. Pure power?
While PrecisionCore printhead nozzles can deliver drops as small as 1.5 picoliters (pl)
(1.5 trillionths of a liter), they can also deliver drops of up to 32.5 pl. The whole pack

Variable Drop Size for Precision and Coverage
It is important to note that in piezo inkjet systems, increasing printhead resolution
generally brings with it a corresponding decrease in the displacement of the piezo
actuator and thus the volume of ink you can jet in a single ring of the nozzle. In
some situations, this may actually be desirable, though for certain inks or printing
surfaces this may require more passes by the printhead or more nozzles to achieve
the required volume of ink. PrecisionCore’s strength is its powerful high displacement
piezo element that enables it to deliver both large and small drop volumes even at
high resolution, thereby overcoming this barrier.
Whether you need large areas of solid color covered quickly, details such as grada

sionCore can efciently and precisely deliver the most appropriate amount of ink to
achieve high-quality, high-speed printing. Inch for inch, the high-resolution Epson
print chips are one of the fastest inkjet printing technologies in the world. The table
