Print alignment
Skew:The amount by which a supposedly horizontal printed line may vary from being parallel with the
edge of the paper. This assumes that vertical printed lines are also at an angle, so that the entire image is
printed correctly but slightly rotated on the page. Measured with a 190 mm (7.48 inch) line.
Within 1.2 mm (0.047 inch) either up or down
Registration:The amount by which images appearing to left or right, or above or below previously printed
images. Images appear on the paper correctly printed and aligned, but not in the same place. Measured
at the mid-point of the side or top of the paper.
Within 2.0 mm (0.079 inch) lead edge
Within 2.5 mm (0.099 inch) side edge
Magnification:The amount by which a line can be greater or smaller than its nominal length. Measured
with a 240 mm (9.45 inch) vertical line and a 190 mm (7.48 inch) horizontal line. These lines are
centered on the page to avoid measuring parallelism errors.
Within 0.8 percent longer or shorter than its nominal length
Horizontal Accuracy (Parallelism):The amount by which the ends of two vertical and two horizontal lines
can be greater or farther apart than the other ends. Measured with vertical lines of 234 mm (9.21 inch)
and horizontal lines 190 mm (7.48 inch). These lines are arranged to form a rectangle on the page.
Within 1.2 mm (0.047 inch) horizontal or vertical either way
Linearity:The amount that three straight lines (horizontal, vertical, and diagonal) can vary from being truly
straight. One end of each of the horizontal and vertical lines meet at a corner; the diagonal line is at 45
degrees to the other two lines and passes close to the center of the paper. The horizontal line is 190
mm (7.48 inch), the vertical line is 234 mm (9.21 inch), and the diagonal line is 269 mm (10.6 inch). The
amount is measured by the distance a line can vary from the position of a true straight line.
Within 0.5 mm (0.02 inch) either side, horizontal and vertical lines
Within 1.2 mm (0.05 inch) either side, diagonal line
Vertical Accuracy (Verticality):The amount one end of a 114.5 mm (4.51 inch) vertical line can vary from
true perpendicular.
Within 0.8 mm (0.03 inch) either side of true vertical
