Introduction

The objective in developing the UltraChrome pigment ink was to combine the long-term and short-term colour stability properties of pigment inks with the colour scale of dye inks. This new colour ink system includes light black as a seventh colour, which makes it possible to achieve softer gradations in the case of black&white printing, as well as two types of black ink, matt & photo, ensuring that optimal quality can be achieved on all media types.
