Samantha and I have used Blurb in the past to make on-demand printed eBooks. Once you figure out the colour management (they have a great resource on that topic), you can make a book filled with images that look just like the images on your calibrated monitor. Very cool! All of our Blurb printed books showed faithful colour reproduction and good printed quality.
When Blurb announced a service where you could turn your existing books into eBooks formatted for the iPad and iPhone, we thought that was pretty slick. You can also use their drag-n-drop templates to create a new eBook from scratch. So I took one of my existing books on Blurb, Winter in the Canadian Rockies, and converted it to an iPad eBook. I don’t have an iPad so I can’t vouch for the quality of Blurb’s conversion software, but you can be the judge! Download it for free and tell us your thoughts. All we know is that, because the eBook is formatted for the iPad, it does not play nicely with any other devices.
