Doing some CMYK School Booster Cards 4/1, and there are a couple Adverts that are required to be grayscale (Restaurant Logos) on the front. (the CMYK Side)

I’ve tried a bunch of thing to get the grayscale logos to Sep out on the K Plate
only, so the pressman doesn’t have to build the black on these logos.

I tried to put the logos into a separate file and make them a monotone C0, M0, Y0, K100. But then pulling them back into the CMYK job on a layer they revert to being seped to all plates again….

Any suggestions?

Try this:

Assuming the logos ore on their own layers, with each logo layer selected make them monotone with Channel Mixer. Then with nothing else visible, copy that layer and paste into the K channel. Then Select All and Delete (or fill with white)on the other channels. Do this for each logo individually.

Then turn on your other layers.

Yes.

Don’t use Photoshop for a page-layout program. Do not assemble your job in Photoshop; use a page layout tool like Adobe Indesign or Quark XPress. You are using the wrong tool for the job, and because of that, your work is more difficult, tedious, and frustrating than it needs to be.

If you really want to do it in Photoshop rather than Quark, open the grayscale ads, convert them to CMYK, and use Image->Adjust->Hue and Saturation. Turn on "colorize" and move the Hue slider to 0. That forces everything onto the black plate. Then move the entire image into the page with the Move tool.

You’re still better off using the right tool for the job, though. If you take existing ads and rasterize them in Photoshop, the text will turn to pixels, and will be inferior quality on press.

Thanks edjh!
Just monotoning them in the color mixer did it.
(after a little adjustment with bright/contrast to bring them back)

I hear what you are saying and preach this myself, but these cards were absolute PS projects with blending layers, photowork, etc. it was just the 3 small grayscales that had to be dropped on them..

And I could of let the pressman handle building the black on the logos, but owning a small print shop myself, I like to make it easiest on pressmen as I can. LOLOL
(they are being sublet out to a big commercial print shop that prints CMYK on mylar and then bonds the mylar to plastic "credit card type material" then die stamps them out.)
