grainy skies in CMYK PDF

[edaviswalker]

Hi there. I have created a publisher layout and am trying to convert
it to PDF for printing. I originally printed the doc using the RGB
color space, but the resulting PDF contained "stripes" in each of the
images - it was like each image was composed of multiple horizontal
bands that all together made up the image. These bands were visible
when printed.

So I switched to CMYK output. This has worked, except that the images
containing deep blue skies have become extremely grainy. I have played
around with resolution with no success.

Are either of these problems that anyone has seen before? I am not a
Publisher pro by any means, but I've tried all the combinations I can
think of. I've tried multiple PDF printers as well, so my initial
inclination is that the solution - if any - is to be found in
Publisher.

Thanks very much.

Dave

Are you using transparency in any of your objects? Try using a tint or
copy/paste the object as a .png.

Thanks, Mary. No transparency. These are JPG pictures cut and pasted
in directly after having been copied off of my camera. I didn't make
any changes besides resizing and cropping. As a result I'm not sure
what you mean by adding tint. But I will try to copy them in as PNGs
and see how that goes.

Thanks.

An update - saving my pictures as EMF files worked. It increases the
size of my layout, but that's a small price to pay.
