Redefining black-and-white printing for the 21st century
Epson UltraChrome
thought possible from a colour printer. Skin tones come alive as never before
and shadows reveal subtleties that were previously lost on other printers.
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 UltraChrome K3 Ink substantially reduces
these problems, allowing black-and-white photographers to fully express themselves using digital cameras and printers with
quality rivalling that of silver-halide processes.
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.
