ich muss für einen Druck in einer Druckerei eingefügte Bilder (sRGB) in einem CMYK-Farbraum abliefern. Das benötigte Farbraumprofil "ISOcoated_v2_300_eci.icc" habe ich unter "/usr/share/color/icc/" abgelegt. Und ich erstelle meine SVG-Dateien primär mit Inkscape, weniger mit Scribus. Die Bilddateien bearbeite ich mit GIMP.
