Hello, my name ist Thomas. I recently did some graphics for a math book using metapost and the context-macros. The context-macros turned out to be a great solution for all the cmyk-problems concerning professional printing. But now another problem occured. When I put some elements (for example fonts) on shaded areas, the color of the shaded areas should go on beneath the fonts to prevent artefacts in printing. But it doesn't, the editor told me. This is called "Ueberdruck" in German, which would be "overprint" literally translated but I don't know if this is the correct word. I hope you understand my problem. If so, it would be nice when you could tell me if there are any options in Context to achieve what I want, it's quite urgent. I'm naturally a mathematician and no specialist in computer graphics, so I know very little about pdf. Thanks Thomas Epp
