The Defect Void Grade cards are offered in Grades A,B,C,D,F (4,3,2,1,0) of void defects for use in testing bar code verifiers. To achieve a void defect, one bar has been altered to include a precisely thin white line in the center of the bar (the whole symbol height, from top to bottom). The precision of this line causes the defect grade to be the same no matter which scan path is used to scan the symbol. Each card is individually serialized, major values are marked on the card, and all values are included in a written report.
