Duotones - issues?

[jo achin]

I know I've seen this topic on the forum before, but I can't locate the question.

I'm creating tradeshow graphics, and I would like to convert the photographs into duotones. Is there anything I need to watch out for RE: print production?

(Duotones will be PS EPS files w/ transparent background placed/linked into Illustrator EPS file)

Thanks

Jo,

>>w/ transparent background <<

You will need to create a clipping path for the transparent area as that's
the only way EPS can carry transparency.

If creating monotone 'duotones', a better way might be to convert to
greyscale, save a tiff and use an opacity mask in Illustrator to create the
colour

The photos were converted to grayscale, and then I changed the mode to duotone (black & red). Then I exported w/ clipping path, and linked file into Illustrator.

Why do you suggest the opacity mask in Illustrator? Will the color produce better?

Thanks for your reply.

Jo,

No, but duotones placed in Illustrator can be a little hit and miss <g>
