Jim Kelly gives a thorough introduction to professional perfect binding using the Fastback® Model 20 tape binding machine by Powis Parker. Perfect bound books have full bleed wraparound covers that adhere directly to the inner pages of your book, making a paperback document in any size up to 12 inches in length. The heat of the Fastback® bind cycle previously made perfect binding toner-based covers very difficult, as the toner would melt off the sheet. With our innovative spine protector sleeve, however, we've figured out a method to create a very strong perfect bind without compromising the way the cover looks.
