The Root of the Problem

If the coating is not the problem, Lapin said, "The next thing to check is the drying or curing process. Of course, the faster the line speed, the more drying or curing capacity is needed."

Newell suggests that the press or web operator work with the coating or adhesive supplier to establish the proper drying parameters for the product and substrate before a specific job is run. "The run must then be practiced through a period of trial and error until the optimum conditions are established," he said. "Then production can move forward."
