Those 5 books, several broshures and leaflets that I have published
myself, were matching different demands in the printing shop
(printworks) than mentioned in the cited message below.
One of the books was totally 1-colour print (i.e. BW) while others
had large chunks of 4-colour and large chunks of 1-colour print
alternating - just to minimize colour separation costs.
Nothing was allowed to be in RGB. Colour sectors had to be CMYKked,
while BW sectors had to be in grayscale mode (otherwise the system
would have treated them as partially 4-colour job (with some empty
layers) and would have made colour separations anyway.
I had to be extra careful with all tiny elements (illustration frames
or figure captions or page numbers) to keep or to change them in(to)
Grayscale mode instead of colour modes.
But it depends on the particular workflow, I guess.
To know in advance how the thing is going to look like is based on
careful and calibrated workflow. If you are able to convert your
calibrated vision into a printfile (ps or pdf), then it must come out
OK. If you deliver the printshop an "open" file (Illustrator or
InDesign or PageMaker or similar), you also have to deliver a
printout maquette on paper in real colours and with printmarks . . .
or be pleased with what they produce for you.
Perhaps it is out of context, I didn't follow the beginning of this tread.

RGB I think is what is requested by the "printer". I suspect sRGB
would be OK too. But not CMYK.
Searched the lulu.com site a bit and here what i got...

please read
========================
Should I use CMYK, RGB or Grayscale images?
Use RGB for both color and black & white books. We've had people
report that when you save your image files for printing in a black &
white book, saving in Grayscale causes them to pixellate upon
printing. We therefore recommend setting the color mode of all graphics to RGB.
Why do I have to use RGB images?
In short, it's because our printer uses a CMYK printing process.
Sound contradictory? Well, no... read on.
When you upload an image that has an RGB palette, the printer
converts it to the appropriate CMYK color. If you upload an CMYK
image however, it may use your CMYK palette map. The palette mapping
of your monitor, however, does not match that of the digital
production press that our printer uses. This causes the colors to be
off, sometimes very wildly. To keep your colors as true as possible,
always upload RGB images.
How can I make sure my images will print exactly as I want them to?
When you include illustrations, photographs and other images in your
book, most times they will print correctly. There are a few things
you can do to ensure the picture quality is what you expect.
Before uploading, print your source document and review how the images print.
If you are uploading a PDF, print the PDF and review how the images
translated into the PDF.
After Lulu converts your file, you must view and approve the
conversion. Click View, then use your browser's print function to
print a review copy.
========================
take note on the last paragraph,
and the fact that they print in CMYK...that means blacks ashing out (for me)

huh? :)
forget iut..it would be a question on how we would get a solid copy
of the book but i have found out
===============================================
so... no matter what, CHEER UP MY FRIENDS! Life is too precious to
jump the other side of the fence...
