Accurate Ink Placement
One of the key factors in achieving
absolute clarity in prints is precision
in the ink droplet formation process.
™
By utilising Micro Piezo
technology,
as opposed to a thermal or "bubble"
system, the Micro Piezo print head is
capable of controlling the curvature
(meniscus) of the upper surface of the ink
column at the print head nozzles. This
Advanced Meniscus Control (AMC)
technology enables the Epson STYLUS
PRO 800 Series printers to deliver sharp,
accurately placed spherical ink droplets
on the print media.
With accurate ink placement comes
the ability to create prints that exhibit
detail so fine that it exceeds the quality
delivered by more expensive
printing devices.

Superb Quality –
Excellence with Every Print
Epson's commitment to superb print quality is underpinned by
advanced technologies that have been a hallmark of Epson's
global leadership in professional colour and black-and-white
printing. These are technologies that ensure every print
benefits from:
>
Incredibly accurate ink droplet placement
>
Precise control over variable sizing of ink droplets
>
Accurate colour matching across multiple printers
of the same model
Precise Ink Droplet Sizing
For each of the resolution settings that can be made with the Epson STYLUS PRO 800
Series printers, the Micro Piezo print head utilises a specific set of three different size
droplets – any combination of which can be produced in one pass of the print head
and through each of the 180 x 8 print nozzles. At high resolutions, these ink droplets
can be as small as 3.5 picolitres – four times smaller than the diameter of a human hair.
This precision control over ink droplet size is achieved by means of Epson's Variable
Sized Droplet Technology (VSDT), which is instrumental in delivering true 2880dpi
resolution.
The advantages in professional printing of VSDT are increased print speed by using
larger droplet sizes for image areas of the same colour; and, in conjunction with the
™
Epson AMC technology, superb detail with accurately placed smaller droplets.
Accurate Colour Matching
In production environments where several printers of the same model are being used,
colour consistency between prints is essential. In a change to the production process,
Epson introduced colorimetric calibration of each printer, checking and correcting its
calibration using precision spectrophotometers. As a result, colour proofs, from
different printers of the same model remain consistent between one another.
