Variable Sized Droplet Technology
By controlling the electric pulse applied to the print
head's Piezo element, the Epson Stylus
print head is capable of
producing several different sizes of ink droplets,
depending on the image type and media used. This
new generation of MicroPiezo
the Variable Sized Droplet function to improve image
quality whilst optimising print speed.
2880 x 1440 dpi Resolution
The Epson Stylus
Pro 7890 and 9890 offers industry-leading
output quality, with print resolution of up to 2880 x 1440 dpi.
This is achieved as the result of technologies that include
Variable Sized Droplet Technology, which supports ink
droplets as small as 3.5pl, and Advanced Meniscus
Control, which enables the printer to deliver sharp,
accurately placed spherical ink droplets with high
levels of precision.
1440 x 1440 dpi Mode
With the addition of a new print resolution, 1440 x 1440 dpi,
which can be used in conjunction with a third-party RIP,
the Epson Stylus
Pro 7890 and 9890 deliver improved quality
and dot sharpness when generating 1 bit TIFF proofs.
• Smoother Gradation:
In combination with the 8-colour ink system, the new
LUT technology delivers prints with noticeably smoother
colour gradation and transition.

Print Speed Comparision
High Speed Throughput
In contrast to their predecessors, the Epson Stylus
and 9890 are able to achieve print throughput at rates of
up to more than twice the speed*.

Advanced LUT Technology
Utilising a new and sophisticated colour LUT (Look-Up Table)
technology, the Epson Stylus
achieve high levels of optimisation in the key image quality
LUT with poor grain
• Grain Reduction:
By improving the ink combination selection process, the new
LUT technology dramatically reduces instances of image
grain that tend to be prevalent in skin tones.
• Colour Constancy:
With a colour constancy level of less than DeltaE 1.0, print
colours remain visually consistent when viewed under
different lights and lighting conditions.
