I've used Blurb, Apple and SharedInk. I found Blurb to have the worst quality for monochrome
I have printed my book on Blurb and while
I've read of others' disappointment with the
print quality, I've been very pleased with
the way Blurb has printed and bound mine.
So far, I've sold over 100 copies, and not
one person has written to complain about
print or production quality. My book is 160
pages, with 120 or so B+W photographs,
and it would have been impossible to print
affordably through services like SharedInk.
I was not keen on the Blurb page templates
so I got around them by setting my own pages
and producing each as a JPG file that I then
fed into Blurb's software as a full-bleed image.
For text, I would set each page as a Word file,
so I could control leading and page breaks and
typefaces through Word. Then I would print
each page as a PDF; import the PDF into PS
(well, into Elements, I don't have PS); set the
PDF on a canvas the same size as the book
page; and then save the file as a JPG, which
I then imported as a full-bleed image into
BookSmart. Photographs were simpler: I
would resize each for the book; increase the
image's canvas size to the size of the book page;
type in a caption underneath the image on the
canvas, using Elements' Type Tool; and then
save it as a JPG and import it into BookSmart.
So, each page in my book, including the title
page, is a full-bleed JPG I created in Word and
Elements. The resulting pages look exactly the
way I envisioned them, for better or worse.
