0 % is the best achievable factor, meaning the dot transfer is perfect, the horizontal
and vertical lines of the measurement patches have the same thickness and that nei-
ther slur nor doubling eects are present. Values up around 5 % still are acceptable.
%-values higher than 10 % indicate signicant geometrical errors in print due to slur or
doubling eects. There are no standard values for the maximum allowable %-factor.
3. The third measurement on a vertical lined
patch. After the measurement of the vertical
lines again the dot area of the patch is calcu-
lated and stored (see the following gure).
As a result the so-called slur/doubling factor
in % is displayed.
