2-some, LFP, dyestuffs and fastnesses eng

The trend toward more colorants that just the standard KCMY one creates the opportunity to
enlarge the printer gamut and to produce more brilliant inkjet prints. With the introduction of
additional colorants it is furthermore possible to reduce the well-known pixeling.

We advice you on the correct colour combination to achieve an optimal and consistent result.

The end-product requirements determine the type of dyestuff (reactive, pigment, acid, disperse),
the dyestuff (fastness) and dyestuff combinations (metamerism).

The choice of application (combination of dyestuffs, substrate and process) in part determines
the fastness and print quality (brilliance, sharpness, smoothness, etc.) that one can obtain in
the end.

Stable dyestuff combinations are to be preferred, that are combinations that for different light
sources (daylight, evening and artificial) lead to small deviations in appearance only (metamerism).

An important criterion in the dyestuff selection is the fulfilment of eco standards, in particular
with regards to labelling requirements.
