CMY over 2 SPOT colours

[Gui]

Sorry for bad english, I'm probably only boy on these forums from Serbia & Montenegro.
Anyway I'm trying to finish one cover in which I want to apply CMY picture over 2 SPOT colours(something like "Milka" chocolate). I manage that in AI10 (small vector CMY images with shadows and tranparencies over 1 SPOT colours, even perform mixture of all 4 colours) and it come out well. But, now in AP7 I'cant resolve similar thing.
Waht I have now is duoton image (PANTONE 215c and PANTONE 222c), and I want "somehow to move it" in CMYK-Doc, and replace "K" with PANTONE 222c. I tried almost everything. Is it possible anyhow?

I'm not sure I understand (and trust me it's me not your english) Do you wqant to convert a cmyk file into a duotone? You need to change it to grayscale then a duotone, then fool around with your histograms, make sure that 100% ink is Pantone 222

Thanks, but i've read all posts made by others members and in one of them (Hiya, The PS 7.0 manual is vague. I hava a two channel DCS. I need to go 4cp. But with no luck, my conversions go gray scale..... I am missing a step or two..... thx in advance*** posted by Davey ), I find solution.

Anyway, thanks.

What your saying is you want to take an image that is now a duo tone (2 inks) and convert it to CMY + Spot?

Lammy, Duoton to CMY + 2spot(duoton), it is very easy, I menage to resolve the problem I had, just by reading the past "posts" on forum.

If you need to transfer a duotone as spot color channels into a cmyk document, turn it into a multichannel file and the duotone ink colors will become spot color channels. Then you can copy them into new channels in the CMYK file.
