H Ernst/John: Where do i set CM to OFF within Qimage. I have set it off in the printer properties dialog for IPF i.e. Color Mode = No Color Correction. Is that what you are referring to when you mention -
Flexible and transparent in the printing phase and OFF is OFF in the settings.
thx
Down left click on the Printer ICC profile entry and select OFF, a pop up menu explains that the setting is used for profile target printing. Keep your printer driver CM choice on "Let application manage color" or similar phrased setting. Qimage will not do that with CM OFF and the driver will not do it as it expects Qimage to do it. Windows as the OS will not interfere either. It can be different on OS-X, which doesn't run Qimage anyway.
There are more choices on color management in Qimage, from the Wide Inkjet Printers forum:
> 1/ CM-Off = Qimage doesn't convert the file, sends the plain RGB data to

End of quote.
And even that does not cover all Qimage color management choices. When more images are nested on the print page you can alter the profile or rendering choice per image in that page. The first is a nice way to check different profiles for the same paper but hardly used in practice, the last is one that allows you to give one image perceptual rendering while the other images stay on relative colormetric, as an example.
