is there a way to export a page as JPG in CMYK?

for what reason?
jpgs are not a good format for prepress. not good at all. and web work isn't
going to want cmyk.
if a printshop asks for one, they are displaying (unfortunately, for you) a
lack of understanding of the universe of file formats and proper use
thereof.
Herein are some of the problems presented by using jpgs in a prepress
workplace.
1. they are bitmaps. all text wil be rendered in the resolution chosen for
that bitmap. that means it will look chunky and unsharp unless you get up
over 1000-1200 pixels/inch which in a color file presents big (can you say
"farking huge," boys and girls?) files...on the order of over 150 MB per
letter page. The large filesize means the natural tendincy would be to
increase jpg compression
2. jpg compression works like this. suppose you had 4 kids and you decided
to use jpg compression to fit them into two bedrooms each with a private
room. jpg compression means you delete two of the kids. they are gone. jpg
compression is "lossy," that is it throws away data. And it does it every
single stinking time you open it and save it. Ever notice what looked like a
halo around someone's head in a photo? That's usually the result of jpg
compression. And it gets worse each time you save the file.
The alternatives to providing a crappy file like this of a newbie printer
are:
a) provide them with film, made from the publisher file by a service bureau
that is happy to accept your Publisher file and make film from it. Yes,
there are many. I, myself, am one.
b) find a different pritner, one who is happy to accept your Publisher file
and work with it directly. Yes, the are many.
c) learn to create and use PDF files. This will require your obtaining a
copy of Acrobat which will cost a couple hundred bucks or one of the (IMHO
less capable but) less expensive alternatives, such as Jaws (about $120),
etc.
You can find more PDF options at http://www.mvps.org/publisher
hopes this helps. if not, post back at us<G>

Thank you all for the quick replies.
The reason for the JPG file is that we are making a newspaper with publisher, some pages need to be printed in grayscale and some in color, but that is beside the point. The point is that when I send it to PDF (we have acrobat 6) in CMYK it takes forever to create one page, not to mention that we have to repeat that action for each of my color page (B/C publisher does not give the option to select with a comma the pages that are sent to print.)
Is that normal for one page to take like 20 minutes be a PDF file??

Isaac,
Hard to say? That seems to be a bit long, but then I don't know how many
graphics you have in the page, their size, etc.
However, your excuse that you are making a newspaper is lame. (Forgive
me!) I publish a newspaper and have to supply CMYK files. I would never,
ever, even consider sending the file as a jpeg.
Maybe you need to change your workflow. Do each page as a separate file,
or the two middle pages and front/back pages as two files.
Also, look at your settings in Acro. Newspapers are going to print at
85-100 lpi, that means the highest resolution you will need for graphic
images is 200 dpi, if placed at 1:1 ratio. If you are scanning images at
1200 dpi, you are creating unusable pixels that will slow down pdf creation.

20 minutes does sound way excessive.
How are you making your PDF files?
Why not make 2 x PDF files and delete the colour pages in one file and the
B&W pages in the other file.

20 minutes sound quite excessive. here are several possible reasons why this
may be happening (there may be more):
1) image resolution. For halftone/photo images you should need no more than
200 pixles per inch UNLESS you are enlarging the images in Publisher. The
images should be prepared in something like Photoshop BEFORE you bring them
into Publisher. Don't have Photoshop? Look on ebay for an older
version...I've seen PShop 4 go for $35 or so.
2) The inclusion of "paste special" stuff which can sometimes cause the
originating application to be started so data can pass back and forth
beteween the apps. all overhead.
3) The inclusion of complex vector clipart. Sometimes clipart has thusands
of nodes and it can take some time to render these items. Solution here is
to use Photoshop to rasterize it (to 200-300 dpi). Important point
here--vector items ought normally not be rasterized because it converts them
to pixels and looses their resizabilty. In the case of process color builds,
however, the dang things are going to become screened anyway so it makes no
functional difference.
4) related to #3 would be the use of eps from Illustrator, CorelDraw, etc
where there are significant blends and lots of objects. Theser can take
forever to render some times. The solution is to convert them to bitmap--I
particularly like Corel Draw for such putposes because it can do it
internally.
5) you have lots of other things running on the machine at the same time.
stop as many of them as you can. Distiller likes to have cpu cycles.
There are many procedures for making a PDF , even with Distiller.
The only one I use (and I've been using PDF in prepress since Acrobat
version 1) is to first print a postscript file then distill it.
I do not like the "automatic" pdf creation things, whether from Adobe or
not, because they--to me-seem to involve to many extraneous processes.
if you don't want to sit and watch, set up hot folders. And print your
postscript files to them. Make certain your distiller job options are set
BEFORE you turn it loose.

What other options do we have to export in CMYK other than pdf?
M
Mike Koewler
There are lots of other options than pdf but, IMHO, none of them is
viable. That doesn't mean it needs to take 1/3 of an hour to send a
page. You need to go back to the basics, insert images at 100 percent
size (if they are too large, then resize in an image editing program),
for instance.
I don't have Acro 6, 5 tends to do all I need, but there are probably
settings you can change. Ask your printer to e-mail his job options file.

you are right about the images, when I insert them as a lower dpi the pdf is created faster.
I did ask for the job options, and configured my pdf accordingly, though they insist on images in 300 dpi...
if I lower the dpi and send it to them would they know? or would the print be worst?

Isaac,
If they are printing at 150 line screen, you will need 300 dpi images,
if you are placing them at 100 percent size. But if you are placing a
thumbnail picture of an original 8x10" photo, you should resize it in
PhotoShop.

We tried everything… we are desperate
Just making sure that we are doing things right
To make the pdf I have to select the PDF printer, and select print to file, Right
I think our problem is that it creates the PS file before and that what takes it so long
When we select no to print to file, the PDF fails to create
