Paper thickness changed?
I have two paperback books for sale on Lulu. Both are US Letter size with Full-color on White interior. I have ordered five books since October 3. All have been printed on thinner, semi-gloss paper similar to what CreateSpace uses, instead of the 80# Gloss paper listed in the Lulu specs. This makes the spine width narrower, which affects the lettering on the spine. Is this a permanent change? If so, why haven’t the book specs and the spine width calculator been changed to reflect the new dimensions? These books were printed at the Agawam MA facility. I actually like the thinner paper better. The books are lighter to hold, the pages turn more easily, and the mailing weight is reduced.
