So you've proofed the book and you're ready to tell us to print the remaining copies. Once you give us the nod, we will make the changes you've indicated on your proof or signoff sheet and then continue printing the book.
Protecting the quality of the binding
After you spend so much time and money producing a book, it should last as long as possible. Although some binding methods are more durable than others, there are additional factors to take into consideration that will prolong the life of a book. Many of these factors only affect Perfect-bound, which require textiles and chemicals to work together in just the right way. You can protect other types of binding by choosing durable paper for the cover and the inside pages. You should store books correctly in a dry location out of the direct sunlight.
