The calculations between RGB and CMYK is ok, it is the same as in CS.

But the ground-Color are really different. See example here:

Well, Inkscape is unfortunatly not a referenz-programm for printing
(real printing, not "Consumer printing" ;-) ) - so it may be not helpful
for color-adjustment.

You cannot check it on "consumer grade" printer ;-)  I didn´t made a
print jet, even I do not have a referenz.

No, I do not have a real calibrated display, it is "near" calibrated,
but what is the referenz?

There is still another problem. You desided to use a "Vegur"-font as a
standard font. Unfortunatly this font does not have all nessessary
characters (f.e. no "ä", "ü", "ö", "ß") - so it is not possible to use
this font for text.
This was not a very good idea ....

Yes. Or better no. I do have a EPS-Version, I believe it was send from
Bernhard to me some month ago, because I cannot open the svg-file. This
is a inkscape-spezific svg file, adobe is not able to open it....
But: Comparing the distance in relation to the png file it is the same.
Have you ever seen your work on a Windows PC? You know, that there is a
differnz between Linux and Windows Pixel-Width?

Best regards
Thomas
