Title: grayscale settings for offset printing
Greetings: I'm seeking info on correctly converting to grayscale specifically for offset printing. I'm very comfortable doing the actual conversion utilizing Photoshop's Channel Mixer, but its the specific settings I'm hoping to understand. I've had great success with RGB-CMYK conversions, using the specific CMYK - ICC profile from the printer/separator, but am less clear about grayscale. Obviously I can setup my system to convert to grayscale with a 15% dot gain, or whatever the printer tells me, but is that it? If they'll give me their dot gain settings for the quarter tones, half tones and three quarter tones (for the paper/ink combo in question) is there a way to build a better conversion? I haven't seen much written on this, since everything seems aimed at inkjet. The two-dozen "originals" are arriving digitally from many different sources, some untagged, some in various flavors of grayscale already, and many in RGB. I'd like to set up a good workflow for these. Thanks for anyone's insights.
