I have a CMYK colour image which I'm using for a Yellow Pages advert. However I'm only allowed to use one colour for the advert.

So I need to convert this image to tints of that one colour.
The colour available is CYAN and the tints are: 100%, 80%, 60%, 40% and 20%.

How do I do it.

Any suggestions much appreciated.

Cheers

Thankyou for that.

I had been experimenting with the Duotone, but should I enter the different % tints using the Duotone curve or simply add more tints in as seperate colours - turning it into a Quad tone say?

Your best bet there would be to contact the Yellow Page publisher and find out their printing constraints. They'll be able to give you specifications of what values will and won't show up. If you don't work with them, you'll probably be disappointed with the final result of all your efforts when it prints as some expensive semi-posterized image that muddies up the details.
