Product Showcase: Inspection Rewind - April 2014
Inspection Rewind
Quality control is one of the most critical functions to be performed on offline finishing equipment because it is the last time the product is seen before shipment to the customer.
Quality control steps can include visual inspection and/or electronic detection. In a visual inspection system, either a stroboscope or a web video system is used to freeze the printed image so that an operator can assess print quality of the labels and remove any bad product before it reaches the customer. Operators can also be assisted by electronic detection systems that will automatically detect faults such as missing labels, improperly stripped waste matrix, flags introduced by the press operator, millsplices, and even incorrectly printed bar codes to make the quality control operation easier to perform. After detection, defective material is easily removed at a splicing table.
Thanks to Mark Andy for this concise description.
