NOTE: To derive the skew specification for a particular media size, measure the width of the
leading edge in millimeters. Next, divide the measured length by 1000, then multiply by the
appropriate Image Area Tolerance specification in milli-radians. For example, A 5 in. by 7 in.
custom page would have a leading edge width, in millimeters, of 127 mm (5 in.). Dividing the
127 by 1000 (127/1000), then multiplying the result by the 11 milli-radians specification results
in a maximum skew of 1.4 mm (127/1000) x 11 = 1.4 mm.
