Example: nonlinear web growth profile
In cases where it is not practical to assume that the web growth is
linear across the paper, a nonlinear web growth profile can be created
to capture the actual displacements from the base separation.
This topic provides nonlinear web growth profile examples for
distortions occurring either across the web or across and around the
drum.
Example 1: Nonlinear web growth profile-across the web
This web growth profile example uses the same displacement
measurements as in Table 1: Displacements from the yellow separation
across a grid. It uses plate tower 1 for the black separation, plate tower
2 for the cyan separation, and plate tower 3 for the magenta
separation.
