Mark and Eric,
The books probably cost about twice as much as Blurb's would have. For that money I got excellent paper (Mohawk Superfine Ultrawhite Smooth 100lb.), tritone inks, laminated covers, hardcover binding w/cloth spine. There were 36 pages of tritone images and 28 in 1 color (text). Also 4 sets of proofs. The book is approx. 12"w x 11"h. Images on front and back covers.
Puritan uses an HP Indigo printer and I can't remember, or find, the model number, but it was the ability to print in tritones that sold me. I made one trip to meet with the VP, Operations Manager and had excellent communications with him and the production manager. Hollis, NH is about 3 hours from my home and I incorporated a visit there with one to a book designer in Newburyport, MA. I think I would always want to have at least one personal visit with the people doing the separations and such.
The book was the result of a project I had worked on for about 3 years and was strictly done for personal reasons. I printed 30, gifted approx. 20 and sold the balance below cost.
If I ever print an "important" book again I would seriously consider Puritan, but if I do a more informal project would reconsider Blurb, especially for color and with fingers crossed for b&w. My Publisher totally botched the job when I tried them after the first attempt with Blurb.
Happy to try to answer any other questions.
David
