Variable Droplet Imaging Technology
The Océ Arizona 250 GT offers superior print quality and ink economy through the
use of Océ VariaDot imaging technology, the next evolution in piezoelectric inkjet
technology that enables a print head to produce droplets of varying volume. This
differs from the current piezoelectric print head technology that is restricted to the
use of fixed droplets. The use of variable sized droplets results in dots on the media
of varying size (area) and density which in turn allows the use of four-color (CMYK)
printing for all image features. Using Océ VariaDot imaging technology results in
excellent print quality and a superior ink economy over 6-color printing systems.
Océ VariaDot imaging technology allows piezoelectric print heads to produce
droplets of varying volume on demand. This allows the ONYX

software to specify the appropriate droplet size for each specific image feature.
When imaging fine detail such as small type or fine lines, very small droplets can be
used, when imaging areas of tonal transition or quarter-tone values such as skin tones
drops of medium volume can be used and when printing areas of high density such
as solid colors, large droplets can be used.

for Improved Image Quality
Océ VariaDot imaging technology can be compared to painting a room in your
house. You use a large brush size for quick coverage over large areas and a much
smaller, finer brush for detailed areas. Trying to paint a large wall with a tiny brush
would result in many artefacts and trying to paint a fine fresco trim with a large brush
would be very frustrating. In the same way, Océ VariaDot uses the appropriate size
droplet for each specific image feature resulting in the best possible image quality in
every part of the printed image.

for Reduced Ink Consumption
A significant benefit of Océ VariaDot imaging technology is that it allows the use of
only four inks (CMYK) for all areas of the printed image. This is very significant to
the user in terms of ink consumption per square meter because the current "de facto
standard" in the industry is six-color piezoelectric printing. This older technology
uses lighter versions of Cyan and Magenta inks, often referred to commercially as
"Light Cyan" and "Light Magenta" to overcome the image quality problem
previously associated with four-color (CMYK only) printing.
