Thanks
The spot colours I am using are solid Pantone inks, not produced from CMYK.
No CMYK colours appear in the document, as far as I can see.
I need to check this, previously the spot colours would be listed in the Document information but cannot see that in CS2. It only allows two colour modes CMYK or RGB.
In the swatches palette only the registration mark and the two spot colours appear (the spot colour is indicated by the grey circle in the box) but beside this appears the CMYK "Trivial Pursuit" coloured slices. I have used pictures which are monotone files using one of the single Pantone inks.
They Pantone colours show as separate colours in the output separations but this also shows plates for C - Cyan, M - Magenta, Y - Yellow and K- Black. That I don't want and should have nothing on them.
Seem to remember you could get a preview of the image that would appear on each plate - just can't remember where to see it now.
thanks again.
