Back when I first tried the service, I was very disappointed. Books made from Aperture were fine for passing around to family, but they simply weren’t good enough quality to even consider selling to clients.
That all changed a few weeks ago. The 2.1.2 update specifically improved Apple’s printing service. I only tried the book printing service, but assume that similar quality would be available for all items such as cards and calendars.
Color reproduction exceeded my expectations and images held up, even when enlarged to full size in the 8 1/2 x 11 book. Images were sharp and crisply reproduced. I believe that the higher quality your original images, the higher the book quality will be. As it is with all such printing services.
The dust jacket was beautiful and really set off the hard cover book. I can easily see professional photographers using this service to put books together quickly for sale to clients.
The book cost $54.05 including $7.99 shipping by FedEx ground to Seattle. I placed the book order on November 4 and received the finished, printed book on November 12. Eight-day turnaround, including shipping is very good for something of this caliber.
You can save money by printing fewer pages, selecting a smaller book size or by printing soft-cover rather than hard-cover books.
If this single experience is any indication of the quality of the new service in general, then I can highly recommend it.
UPDATE: Amazon has Aperture 2.1 on sale for $156.99.
