I start out with Galaxy Gauge's Color map Pro to get close to what I want. This marvelous document is printed on heavy stock and coated, so that what you see is likely very close to what you get. Then with no document active I go to edit->preferences and set my cmyk palette to Scribus Open Office. I create a "new" color, give it a name, and use the values from the above referenced Color map Pro to describe the color. Galaxy Gauge has wonderful publishing products at very low prices: http://www.galaxygauge.com/ -- John Culleton "Create Book Covers with Scribus" Printable E-book 38 pages $5.95 http://www.booklocker.com/books/4055.html -------------- next part -------------- An HTML attachment was scrubbed...
