Using Fastback PerfectBack LF Strips With the Powis Parker Scoring Machine

After binding your documentpages in a Fastback binder, with our Perfectback LF strip, you need toscore your book cover so it fits nicely around your bound book block.Our Centering Guide enables you to easily and accurately locate scoresfor books up to 1-1/2 inches thick. This is especially helpful as yourbook thickness may be a bit different from what you expected due to thebuildup of ink or paper thickness variations. The Centering Guide maybe used with either the Single Die Holder or the Double Die Holder.

Operation with the Double Die Holder is the suggested mode and will beexplained first. It makes your spine edge scores based on yourdocument's thickness - it also simultaneously makes secondaryappearance scores 3/16" from the spine edge on your front and rearcovers.

A Demonstration Cover in your Accessory Pack summarizes how to prepare and assemble a book.
