Excellence in colour printing
High ink density, greater colour stability and longer archivability are all attributes of
Epson UltraChrome
today. Epson UltraChrome K3 Ink is an eight colour ink set that achieves new
heights in colour reproduction applying advanced ink technology and utilising
the characteristics of pigment ink covered in clear resin coating.
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.
Excellent colour stability
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 gloss levels
New resin chemistry smoothes the surface of the paper when ink is applied
and thereby dramatically improves print gloss levels.
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.
