Every minute counts with today's high-speed container coating lines.  When a spray machine is coating improperly, 300 or more reject cans many be produced per minute. These improperly coated cans will need to be scrapped and production stopped to identify the spray machine. Early identification of improperly coated cans is critical in saving time, money and materials. 

The Nordson Ink-Dot Identification System identifies which machine coats each can on the line by applying a small dot on the bottom of the can as it enters the spray machine.  A different ink color is used for each line so the source of unacceptable coating can be identified and repaired as quickly as possible.
