Three-level Black Ink Technology
Over the years, the majority of silver halide photographs have
been in colour. Despite this, many professional photographers
choose black and white photography due to the simple and
direct expression of the medium, in addition to the power that
black and white photographs possess.
Until now, it has been technically very difficult for black and
white photographers to use digital photography because of
colour twists and short tonal gradation inherent in digital printers.
Epson's new UltraChrome
™
K3 ink substantially reduces these
problems, allowing black and white photographers to fully
express themselves using digital cameras and printers with
quality rivaling that of silver-halide processes.
Smooth Gradation in Highlights
and Shadows
Epson UltraChrome K3 ink produces smoother gradation in
highlights thanks to the addition of the new Light Light Black Ink.
Shadow areas also reveal more detail and produce denser blacks.

Colour Toning
The three black inks and low saturation
inks (such as light cyan and light
magenta) allow for subtle colour tonings.
Demanding professional photographers
will appreciate this feature for producing
various types of monochrome images.

Smooth Tonal Gradation
The three different density blacks found in Epson UltraChrome
K3 produce smooth gradation and substantially reduces colour
twist. The illustration below shows the smooth tonal scale that
is produced using Light Light Black Ink.

Higher D-max with Glossy Media
The Photo Black ink in the Epson UltraChrome K3 ink set has
been improved, resulting in a higher D-max. This is very useful
for reproducing jet black areas. The end result are prints
containing a depth and richness never before experienced
with a digital colour printer.
