In the past, high-volume manufacturing could mean wide variations in output. Not any more, thanks to advancements in coating, drying, curing, web handling and other technologies. 3M engineers are designing production equipment that combines finely controlled processes with the economic efficiency of roll-to-roll manufacturing. The result: 3M’s environmental performance continues to improve, and product tolerances become more and more minute - as small as half a wavelength of light for some surface patterns.
