Working on a B/W ad that will have a spot color. Can anyone tell me what the best way is to add a spot color to a B/W image.
Do I want to switch to grayscale first - or do I want to just desaturate the photo to ahieve the B/W and then add the spot?
Thanks in advance!

You'll need to put the spot color as it's own channel. So when you send to print you'll have a spot color channel and a black channel.

Do you have a decent tutorial to reference? I know this is silly, but I never had the chance until now to use a spot color.

The easist way is to not do it on photoshop. Is the art such that you can use Illustrator or InDesign or Quark for the Spot elements? That way you can just add the color to your palette and use as needed. Otherwise I'd do a google search. Don't have one off hand.
- Not quite understanding fully. I was shown once - in school hot to do this with photoshop. seems like an eternity ago.

Ok I am understanding how to do the spot color. Now to get the image to output as a b/w image w/ the spot, do I need to delete the Magenta, Cyan, and Yellow "plates" from the channels? This would leave me with black and my new spot color channel correct?
- Convert to Greyscale first. Don't just delete the CMY plates.lherb

in CS3 you can use a b/w adjustment layer, then put the spot color over top...if not cs3, you can convert to grayscale, then back to rgb (cmyk) and put the color back in.

Look up "Photoshop DCS" in your Photoshop help:
Prepare an image with spot channels for printing from another application
If the image is a duotone, convert it to Multichannel color mode.
Save the image in DCS 2.0 format.
In the DCS 2.0 Format dialog box, deselect the Include Halftone Screen and the Include Transfer Function options.
Open or import the image in Photoshop, and set your screen angles. Make sure that you’ve communicated to the printer the spot color you want for each of the color plates.
Note: You can place a PSD file containing spot colors directly in Illustrator or InDesign without special preparation.- The photo will be placed into illy so what woody has said above will work just fine correct?
rodzilla - Should. Soler is also correct. I would put that spot color in its own channel. I assume your using Pantone?marychain
- yeah using pantonerodzilla
- are you working on packaging, or an exhibit design comp? Can't think of any other reason why you'd do your layout in Illy vs. InDesign. Your file(s) will be way bigger than necessary.gramme

or you could make it a duotone - and specify the spot colour there.

I would make the image a greyscale TIF, and then drop it into Illustrator or Indesign to apply the color. You can just select the image and make it whatever spot you want at that point. Messing around with DSC 2.0 is about the most frustrating thing EVER, and definitely brings back BAD Quark memories...

I've got my spot color working in photoshop. However once I get the photo into illy, the spot (pms 021) in photoshop doesn't match any of the illy spots (pms 021).
I did save t he file as a psd. Anyone know how I can better match the two?
Can you still add color to a greyscale image, or does it have to be a bitmapped greyscale image?
