More Offset

Contacted offset printer last night and they are going to overnight me samples of their b&w (4-color offset) printing (cards, brochures, posters, calendars). I think that CMYK is calling me back. Oh God - CMYK. They told me what printer they use but I already forgot. Markus made a great point about getting a RIP / Profiles to emulate the end printer. All I know about CMYK is that to get good blacks you don't just set the K to 100% but need to mix other channels as well. Whatever - I'll figure it out. And what I liked about the site was that they gave good instructions about formatting files for CMYK with templates for photoshop.
