Doctors Do Lots

Johnny Stamey, technical product manager for Max Daetwyler, says there are four basic doctor blade style/tip configurations to choose from for all printing applications. These include a straight steel blade with a square edge or no tip, a radius tip blade or round edge, a bevel blade, and a MDC lamella tip or stepped-edge blade. "These four types of blades range in thickness from .004˝-.012˝," says Stamey. "Nonmetallic or plastic blades have all the same tip configurations, but the blade thickness ranges from .007˝ up to 1/8˝, depending on the type of plastic."
