Abstract
Systems and methods of binding sheets by activating a microencapsulated binding agent are described. Each sheet to be bound has an exposed binding surface region near a spine edge. A frontside adhesive system is disposed over the frontside binding surface region and comprises a binding agent that is encapsulated in a plurality of microcapsules. The adhesive system is non-tacky to enable the sheets to be stacked and individually processed until the binding agent is released from the microcapsules.
