Book Printing: Choose Your Paper Stock Wisely

By Joshua Prizer


Which paper stock you choose when printing your book can have a huge impact on your print pricing. Coated or uncoated? Glossy finish, matte finish, or standard offset? What's the opacity? What's the weight? The answer to these questions will determine your paper pricing.

Book paper weights are different than the paper weight measurements you will see in an office supply store. A 20# bond that you would find at Staples is similar to a 50# offset at a book printer. A 24# bond is similar to 60# offset, 28# is similar to 70# offset, etc.

Typically, I would recommend that for a standard book with just black text (no color) and not a lot of images, 50# offset is just fine. If there are a lot of graphics in the book, you might want to bump up to 60# offset to eliminate some see-through from one side of the page to the other.

No matter what, be sure to ask your printer to send you paper samples. There is no substitute for feeling the paper in your hand to make sure your book has the feel you want it to have.

Children's books or coffee table books that are printed in full color need a different paper stock than black & white books. You'll want to think about whether to bump up to a glossy stock to make your pictures really shine on the paper. If you don't like the glare of a glossy sheet, ask your printer if they have any matte coated stocks that would bring out the color of your images without the extra sheen.

Most full color books are printed overseas, where a different standard of paper measurement is used - grams per square meter (gsm). To calculate gsm, multiply the offset weight by approximately 1.5. So an 80# gloss sheet in the U.S. would be the same as a 120 gsm sheet overseas. You'll definitely want a thicker paper stock for your color book versus a black & white book.

Again -- always get samples before making your decision!

Paperback covers overseas are usually printed using 250 gsm or 300 gsm cover stock. In the U.S. that translates to a 10 pt. C1S or 12 pt. C1S sheet. Also be sure to add gloss lamination to give your cover that extra pop!
