Re: File Preparation for 4 color Grayscale offset printing



Kevin thanks very much for the advice.

Actually thank you all for the suggestions.
I guess I'm going to spend the next few days experimenting and tweaking.

Regards,
Vanita

Hi Vanita,

I see a lot of good suggestions here and I believe Rich Apollo's advice is spot on. A grayscale will do just fine for publication magazines. There is no real need to introduce the CMY inks if all you're printing is a B&W image unless you can't live without that extra boost in density. Sure, the proof has be SWOP standard, but the images can be a 20% or 22% grayscale and would be perfectly valid for SWOP specs.

However, if the images are mostly neutral but have some color elements in the pictures, you may want to take Terence Wyse's advice and experiment with extreme K separations.

We use an extreme K separation profile for publication printing of 4C neutral images and the idea is very similar to Terence Wyse. However, I set the black start point very early in the separation and then aggressively curve the black upwards in the midtones using a Heavy GCR setting. The result of the separation should be nearly identical to Richard Booth's method but far less labor intensive. We have had excellent results with this profile for two years running.

Email me if you'd like a copy of my profile but for best results I'd build a new Extreme K profile from GRaCOL. Cheers!
