[Scribus] Print preview and its relation to exported PDFs
Fri Jan 19 01:07:19 CET 2007
I am helping someone test his printing equipment and prepress workflow. He
thought he could use this image:
It is a test RGB image featuring a couple of photos, test charts, and, most
importantly for this topic, a greyscale gradient along the right edge.
Now, the greyscale is supposed to be composed of colors where R=B=G. In Print
preview, when I turn off the Black channel the gradient disappears
completely. That is exactly as I like it (but not as I expected).
When I export to PDF, the situation is exactly as I expected, but not quite
how I would like it to be. The grey gradient is now composed of CMY colors,
and the ballance is somewhat towards yellow.
Although I understand that CMS is supposed to break down RGB greys into CMYK
(therefore grey being separated to all CMYK plates instead of only K)
wouldn't it be better if there was an option of forcing greys to use only K?
Am I missing something when exporting PDF or this is a whishlist item?
