There are other things to consider, in some cases. If the print is both off-color, and it
has lines in it, then you will need to run both types of analysis. Following are a few
rules that will guide you through this process:
> The color balance of the Test Print is very wrong: The grey looks entirely like some
other color.
-- Even if the Test Print has lines in it, run only the Densitometer Analysis this time, then
make your next Test Print.
> The Test Print's color is moderately or slightly wrong: The grey scale has a tint of
another color, or some of the patches look a little off-color AND the Test Print has
lines in it.
-- Run both the Scanner Analysis and the Densitometer Analysis. Run the Scanner
Analysis first, then read it on the Densitometer. After both analyses are complete,
make your next Test Print.
> The Test Print has lines in it, but the color looks correct
-- Run only a Scanner Analysis. Then make your next test image.
> The Test Print's color is wrong, but it has no lines in it.
-- Run only the Densitometer Analysis, then make your next test print. If the color
correction was large (the color was very wrong), the Densitometer Balance
effects may cause lines in the next test image, so another Balance cycle will
probably be needed.
In summary, Densitometer balance changes (made by running the Densitometer
Analysis) can introduce lines into the next print. The Scanner Analysis will not
affect the color of the print, unless the lines in the print are very severe.
