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.

M0EDIM2802

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.

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)".

2. Creating the Auto Color Diagnosis Property

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.

If Changing the Color Profile for the Same Paper

When you change the color profile, it is recommended to change the profile in the paper catalog, and

then newly generate Auto Color Diagnosis properties. For details, see page 16 "Generating Auto

Color Diagnosis Properties Again".

For better correction, execute calibration before generating Auto Color Diagnosis properties.

Printing

• On Fiery, it is recommended to change the color profile in "Media Catalog". If you change it in the

print job setting, Auto Color Diagnosis might fail to function.

If you change the color profile on Fiery ([Job Properties] [COLOR] [Output Profiles]), if it differs

from the calibration set linked to the color profile used for generating Auto Color Diagnosis properties,

the properties fail to match, causing Auto Color Diagnosis to be disabled.

2. Creating the Auto Color Diagnosis Property

Creating the Auto Color Diagnosis Property

To use the Auto Color Diagnosis Unit function, print the color chart and generate Auto Color Diagnosis

properties for each paper type. When generated, this information is stored in the machine's data storage

and used for adjusting colors when printing is performed.

To generate and display Auto Color Diagnosis properties, use the "ACD Property" screen.

Using the "ACD Property" Screen

The "ACD Property" screen displays a list of paper types that can be used on the machine. In the screen,

you can generate Auto Color Diagnosis properties, check the generation status, and specify the

accuracy setting of the information.
