Re: [libreoffice-marketing] branding colors - missmatch

Hi Thomas!

It seems you are one of the very first to start working on "real" press

issues.

Sorry, I think I don't get the idea of the file. Could you please
explain a bit?

True, but I had to rely on what's available :-\

True, I just wanted to know what kind of output you used / intended to
use.

Let's say, given the time and opportunity, it was okay to go with this
font (in my opinion). Thus, we knew that problems in advance, but since
it is rather "neutral", substitutes for remaining text should work well.

Okay, I'll send you (and Ivan, whom I CCed ... asking him to check the
files as well) updated files. It would be great if you could try the
SVGs, as well as the EPS files.

I've seen some of the "outcome" on Windows PCs, of course.
