[Scribus] color correction

[Christoph Rudorff]

Hello!

Question about color correction.

Got a lot of experience with CorelDraw. 
I got a color reference book of my printing company. If I want a special 
fancy color, I can look it up in the book, enter the CMYK receipt, and 
it will print out like this.

1. make new scribus document
2. doesn't matter, if cms is enabled or not
3. define 2 new colors: 
blackK = 0/0/0/100% CMYK
blackCMY = 100/100/100/0% CMYK
4. draw 2 rect. and fill with the two new colors
(note, the two blacks look equal on screen, but with enabled cms there 
should be a noteable difference between them! Try this with Corel or 
Photoshop!)
5. print/print color separations to file
6. view this file with gv

mh, the blackCMY was converted to 0/0/0/100 !

To my mind, this is not correct. The cms should only correct for the 
display, and correct RGB for printing.
CMYK Objects should not be touched, only if color coverage is more then 
280% because otherwise this will glue and stuck the paper in a offset 
printing machine :=)
In Corel this is an extra option which has to be enabled.

Now who is responsible for this? A printed color reference is the best 
preview u can get. But it does not help if something mixed it up again 
:-(

Any ideas how to handle this?

ps: can anyone verify this with placing CMYK bitmaps in scribus? I dont 
have some right now ...
