2. Make sure that if you are calibrating for plate, the Manual Feed Tray option is

4. Change the Linearization window LPI setting in the Print box (fig. 3.168) to
achieve 256 levels of gray for the resolution at which you are printing.
For 600 dpi, select 85 lpi; for 1200 dpi, select 106 lpi. Any lpi may be used; measure the
lpi that is to be used for the final output.
5. Print a Calibration Page to measure the printer's current performance as a basis
for the calibration. To do this, use the following procedure:
Always print the calibration page using the same media and toner or press ink as used
for the final copy. Also, when possible, calibrate from the final output. For example
when calibrating for plates, take the plate to press and print. Then, measure the
output from the press.
a. Select Emulsion side down if you want to print a mirror image. The
printed calibration page will still look like a positive, but the patch (box)
values will be reversed.
b. Select the custom Gamma Curve you want to update from the Update
Transfer Curve list. This curve selection automatically updates the LPI
option to match the lpi listed for the selected curve. To select a different
lpi setting, use the LPI option and scroll to the desired setting.
If you select a custom lpi for a listed curve, the lpi listed in front of the curve's name
in the Update Transfer Curve box does not change to match the new lpi. In this case,
you need to keep a record of the new lpi setting for that gamma curve.
