Joel Friedlander has posted an article at www.thebookdesigner.com about making good PDF books. As he points out, the PDF version of a book is important at every stage of the production workflow. It can be used for proofing, printing, eBook conversion, archiving and retailing. Friedlander's article gives readers a few tips about how to produce PDF books that look like their paper equivalents.
As he puts it:
It's good to know how to make a PDF book. There's a market for books in PDF format, especially for heavily illustrated books, art books and photography books. Whether you decide to offer your book for sale directly from your website in PDF or not, you are going to use the PDF of your book for lots of marketing and publicity tasks.
For instance, on a review campaign you might offer reviewers the book in ePub, Kindle, print or PDF versions. I've found lots of reviewers like the PDFs. You can deliver the book as quick as sending an email, and it's an exact replica of the printed book.
OK, so you want to stamp your document. Maybe you need to give reviewers some advice about the document's status or sensitivity. This tip from author Ted Padova demonstrates how to add stamps with the Stamp Tool along with related comments.
