Dear David

Thank you very much for your support and comments.

First of all, I shall change now my workflow towards Tiff's (as I 
would get an even worser result on the jpeg-route since I use Neat 
Image as well sometimes).

Second, I shall try to find the correct printer setting to print 
without driver color management. With this printer, it is - at least 
for me - not the easiest thing to do. I think now that there is the 
rub...

With kind regards
Rolf
