A process is provided for producing booklets, such as bank check booklets, having variable printed information. A paper stock for the booklets, perforated for separation into panels, is coated with a catalyst along certain surfaces. After passage through a non-impact printer, such as a laser printer, the panels are separated and stacked in such a way that the surfaces coated with a catalyst extend along an edge of each panel, with these edges being aligned in a common direction. When the coated edges of each stack of panels are subsequently pressed against an adhesive layer coated on a binding cover, the catalyst begins the process of hardening the adhesive in the layer.
