Color Management
7 Color Management
The whole subject of "Color Management" is highly complex, occupies various
professions and fills countless specialist books. We try to give you a brief overview and
a basic understanding in this chapter, at least in case you have not dealt with this topic
in the past.
Basically, any inkjet printer is a device, firing ink drops onto surfaces. How these ink
droplets behave and which colors and intensities finally result is due to so many factors
that we as the manufacturer cannot foresee and cannot take many framework
conditions into account:
· Is the background white, colored, grey, yellowed or in any other color?
· How "white" (white is not white!!!) or how "colored" is the material?
· Is the substrate absorbent, smooth, glossy, matt, dull, rough or porous?
· How does the substrate absorb the ink?
· How does the ink behave on the substrate? How well is it cured?
· Do the drops constrict to form very small and isolated dots or do rather spread and
run into each other?
All these and many other factors will have a considerable influence on the
representation and effect of the colors their appearance on the substrate. In addition,
many print-specific challenges such as dot gain, ink thickness, area coverage, black
level, ink density and gray balance are to be taken into account.
All these factors are - of course - no insurmountable problems, but they demonstrate
the many demands and challenges that inkjet wall printing poses. You should not
underestimate and at least basically understand. So you will learn over time how to
draw the right conclusions in certain cases and then deliver perfect printing results on
as many different surfaces as possible.
