Packaging artwork often contains multiple instances of the same information. For example, the product name and strength will often appear on multiple faces of a carton, or will be stated many times within a leaflet.

Many recalls have occurred because one or more instances of this information were correct, but others were not. For example, it is easy to imagine how this sort of mistake can be made by an individual who verifies one instance of the information is correct and then assumes the other instances are the same.

Therefore, we would recommend that proofreading methods explicitly require all instances of the same information to verify as correct whilst proofreading activity is being performed.

Furthermore, we would also recommend that critical information such as product name and strength are checked across all artworks of the same finished product to ensure that these are also the same.
