The unit is capable of examining an envelope and determining key features of the envelope, such as the amount of front seal adhesive present, the tear strength of the side seams and the presence of properly printed graphics. The unit comprises a) a housing having either a touch screen video display unit or another source of data entry; b) a front seal control portion that contains linear encoders to determine the amount of adhesive on the seal; c) a side strength control portion that contains blades used to measure the force needed to burst the sides of the envelope: and d) a print design quality feature that is utilized to confirm the quality and location of any printing on the envelope.
