It would be really cool to have joined you to talk about colour
management with KDE. However I am very likely to be swamped with work
during this time.
With the help of OpenICC some work has been done inside the Oyranos
project about printing. The Kolor Manager configuration panel shows
some of these. It would be cool for CPD to deploy Oyranos device ICC
profile configuration to create a good user experience. I am about
preparing some schematic diagrams, which can give some condensed input
from the latest OpenICC discussions around linux colour managed printing.
