On display at the Henkel stand is a camera monitoring system, Smart Control, that can be retrofitted to perfect binding machines. It consists of a thermal camera that transmits images of the gluing process to a computer. The function includes computer analysis of each single copy to check the quality of the glue layer.

According to the company, customer feedback on Smart Control, which is already installed on six bookbinders, has been very positive. Henkel said early feedback indicates reduced reject rates, improved binding quality and cut adhesive usage.

Purmelt MicroEmission Cool 3400 is the latest development from the Henkel stable of hotmelt adhesives with an application temperature "much lower" than that of standard products.

Henkel claims its latest development contains 0.1% monomeric isocynates compared to up to 5% in conventional hotmelts. As a result it is exempt from hazard labelling and negates the need for expensive extraction systems.
