Property
Setup before Use
To use Auto Color Diagnosis Unit functions, it is necessary to execute calibration, print color charts for
each paper type, and generate Auto Color Diagnosis properties in advance. If the paper to use is not in
the paper catalog, register the paper and link it with the calibration set (target gradation characteristics)
for the paper.
Execute calibration with the specified calibration set to achieve the optimal gradation characteristics,
and then generate the Auto Color Diagnosis properties to use for Auto Color Diagnosis.

Finish
Registering the Paper
For Auto Color Diagnosis Unit functions, it is necessary to specify settings for each paper type. Auto
Color Diagnosis Unit functions cannot be used for manually configured paper. Be sure to register
the paper in the paper catalog.
When using paper already registered to the paper catalog, it is not necessary to register it.
7
Performing Calibration
By executing calibration, the difference between the printed color and standard color is corrected
to achieve the optimal gradation characteristics.
If not using an existing calibration set (target gradation characteristics), create a new one.
Be sure to execute calibration before you generate Auto Color Diagnosis properties.
Linking a Calibration Set to Paper
For Auto Color Diagnosis Unit functions, it is necessary to link the correction curve by calibration for
each paper type.
On Fiery, color profile names in "Media Catalog" are used for identifying calibration sets.
Generating Auto Color Diagnosis Properties
Generate Auto Color Diagnosis properties in order to register the optimal gradation characteristics
for the paper as the parameters for Auto Color Diagnosis Unit functions.
If you print on paper for which the Auto Color Diagnosis properties have been generated, Auto
Color Diagnosis Unit functions automatically.
Managing Profiles on Fiery
On Fiery, it is recommended to use "Media Catalog" to specify the profile for each paper.
If using the server's default profile, be careful when switching paper. For details, see page 9 "When
Changing Paper".
You can also operate the machine while changing the server's default profile without specifying a profile
for each paper. For details, see page 20 "Changing the Server's Default Output Profile (Reference)".

Recommended Procedure
When Using a Type of Paper Not Used Before
When using a type of paper not used before, Image Position (to align the print position) and calibration,
link the calibration set for the paper, and generate Auto Color Diagnosis properties in advance.
For details, see page 14 "Creating a New Auto Color Diagnosis Property".
Also, to ensure uniformity in in-plane density, we recommend you perform the Density Difference in
Operator Adjustment Settings before calibration.

If the Auto Color Diagnosis Properties Have Been Generated
If the Auto Color Diagnosis properties have been generated, Auto Color Diagnosis Unit functions for the
paper.
To keep the gradation characteristics optimal, execute calibration when starting the machine each day.
(As required, execute Image Position before calibration.) Calibration before printing is recommended,
especially for reproducing colors.
M0EDIM2804
PrintingCalibration
When Changing Paper
When changing paper, it is recommended to execute Image Position and calibration in advance. It is
especially recommended to execute calibration each time you change paper when you use the same
color profile for multiple paper via Fiery.
This is because colors are prone to change substantially because of the influence of other papers when
sharing the color profile between multiple papers.
