Dramatically Reduced Metamerism
The characteristics of pigment ink and reduced colour ink consumption minimise the
effect created when objects having different spectral distributions look alike under one
light source, but appear different when viewed under another. This results in more
consistent looking prints, even when viewed under different light sources.

K3
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.
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.
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.

Wider Gamut
Thanks to Epson’s high density UltraChrome
™
K3 pigment ink, colour prints exhibit
a brilliance and depth superior to that of colour offset printing and silver halide
photography. The wide colour gamut produced by Epson UltraChrome K3 ink
surpasses that of the Euroscale gamut and the yellow, green and red areas of Epson
UltraChrome Ink.

Excellent Colour Stability
Making it Ideal for Contract Proofing
When Epson UltraChrome K3 Ink comes into contact with the
substrate, the ink quickly separates from the pigment particles
which are absorbed deep into the media. As a result, colours
become resistant to change and stabilise quickly. Superior
short-term colour stability allows for high-precision contract
proofing and speeding-up of operations.

Highly Improved Print Gloss Levels
New resin chemistry smoothes the surface of the paper
when ink is applied and thereby dramatically improves print
gloss levels.
