The Epson UltraChrome
In building on the successes and advances of Epson UltraChrome Ink,
the Epson UltraChrome K3 Ink Set is without rival. Featuring a set of
three shades of black ink – hence the K3 denominator – UltraChrome K3
colour and black and white prints display a high level of quality not
previously seen from an inkjet printer.

Ink Overview
Epson UltraChrome Ink has established
itself as the standard among professionals
and high-end users who desire high
quality and durability. Epson UltraChrome
K3 is an improved version of this ink and
was developed based on feedback from
our customers.
Its new pigment and resin improves
glossiness and D-max readings on glossy
media and exhibit reduced metamerism
(i.e. colour inconsistency under different
light sources). Additionally, three levels
of black ink dramatically improve grey
balance, (which is the axis of colour
imaging), and produce superior black and
white and colour prints.
Accurate Colour Control
Epson UltraChrome K3 ink uses three
blacks to achieve a more stable and
accurate grey balance while also allowing
for more accurate colour control due to the
smaller quantity of colour ink used.
Professional users will appreciate this high
degree of colour accuracy when printing
proofs, photographs and limited edition
fine art prints.

Improved Grey Balance
Compared to Epson UltraChrome ink, new Epson UltraChrome
K3 ink dramatically reduces colour twists in grey areas thanks
to decreased colour ink consumption. This reduction greatly
improves colour accuracy for both colour and black and
white printing.
