CMS Option Tool Setup

This section describes the setup of the CMS Option Tool. The CMS Option Tool should be installed on a remote PC where the GUI is also present.

Prerequisites to setting up CMS Option Tool

The following are required before setting up the CMS Option Tool:

• You must be logged in as an Administrator or a user with Administrator privileges.

• Ensure the remote PC being used is connected to the network.

• Resolution of the screen must be set to 1280 x 1024 or greater.

• The remote PC must have at least 300 MB or more of free disk space.

• The GUI software must be able to connect to the Controller.

Color Options

Color options can be selected for an individual job. To view color options for a job, perform the following:

1.

Open Job Management.

2.

Select the desired job.

3.

Select [Properties].

4.

Select the [Color] tab.

Any selections made on this color tab are characteristics of the printed output for the desired job. If an option is greyed out, it is not selectable.

Color Resource Set

A color resource set is created at the PC-GUI and is used to transmit color characteristics to the printer for the given job. Options are available in the pull-down menu. Select the System Default if there is no desired set.

Convert CMYK/RGB Black to K

This option is available for PS/PDF. You can choose whether or not to map the black in an input color space directly to the black in an output color space.To convert CMYK/RGB Black to K, select the Color tab of the Properties window. Select the pull-down menu on the Convert CMYK/RGB

Black to K option. The black of the input color space is mapped directly to the black of the output color space. It is only effective for K 100% or RGB data.

Black Overprint

This option is available for PS/PDF. You can choose whether or not to overprint on the black portion of an input color space, without printing the under-color. The Black Overprint option is available on the Color tab of the Properties window. When this option is selected, the black of the input color space is overprinted.

This is only effective for PS/PDF data and applies only to characters and graphics, not images.

Color Characteristics

Color characteristics are displayed on the Color tab of the Job Properties window. The window is divided for Upstream and Downstream printers. The Upstream refers to the first printer,

Downstream is the second printer. If you are using a simplex printer, you will make selections for only the Upstream printer. If selections are made for a duplex configuration printer, selections will need to be made for both the Upstream and the Downstream printer. The following information is pertinent for both Upstream and Downstream printers.

Black & White printing is available in the Color Mode option.

In a Duplex printing mode, both printers must be in the “Not Ready” status before changing to the Color Mode.

Printer Name

Select the desired printer from the Printer Name pull-down menu.

Print Data

Select the output screen characteristics of the print data. Select the [Setting] button to open the Color Characteristics Upstream Print Data dialog box.

Print Mode

Select Color or B/W. (Color is the Default.)

Resource Group Name

The file name of the color resource group can be specified (None is Default.)

User TRC

Setting of the User Toner Reduction Curve (TRC). This is only effective in the Color mode. Select

[Browse] to adjust the TRC.

Simulation

Specify RGB/CMYK color simulation to be performed on the input data. The following options are available:

• Device

• Ink Simulation

Intent

In the Intent option, specify the way to map the ink simulation from the pull-down menu and select one of the following:

• Perceptual

• Relative

• Saturation

• Absolute

Color Space

In the Color Space option, specify the color space for ink simulation.

Image Quality

In the Image Quality option, specify the image quality to be used for ink simulation from the pull-down menu. The following options are available.

• Business Document

• Photo

You cannot specify this for RGB data in PS/PDF.

Perceptual (Default of RGB)

The rendering technique is specified so that compression or expansion will be performed according to color spaces of the device. This will reproduce all color spaces of the images.

In general, the saturation and lightness will be lowered.

Color Management Guide 1-5

Color Management Overview Xerox 490/980 Color Continuous Feed Printing System

Relative (Default of CMYK)

After dynamic range compression is done, colors that can not be reproduced will be converted, lightness will be sustained as much as possible, and saturation will be decreased. This is not intended for conversion of wide dynamic-ranged images, or high key and low key images.

Saturation

The saturation option is specific for pixels in images. When saturation is changed, it changes the hue and lightness of an image.

It is not recommended to change this option for photos, but is useful for conversion of graphics and charts for presentations.

Absolute

The Absolute option allows colors of reproducible areas to be converted correctly. When colors are converted, lightness is similar to original and saturation will be decreased. For colors in areas that are not reproduced, halftones will decrease significantly. It is not recommended to choose this option for conversion of wide dynamic-ranged images, or high key and low key images.

Output Screen Characteristics

The following options can be selected on the Output screen:

• Screen Job: Selects Halftone Dot [Not Selectable]

• Halftone Dot Shape: Circle [Not Selectable]

• Select Frequency: Choose from 80/100/120/150/200/300

Note

PS/PDF must be the same setting in upstream/downstream. It is only selectable on the upstream system.

Screen Angle: Select C:15

o

M:75 o

Y:0 o

K:45 o

[Not Selectable]

User TRC

When the Browse button of User TRC is selected, the Edit TRC window is displayed. Make any desired changes on the Edit TRC window.

Pre-Printed Paper

Select the output screen characteristics of the pre-printed paper. Select the [Setting] button to open the [Color Characteristics [Upstream] (Print Data)] dialog box.

Custom ink settings

If an ink is to be used that is different than either of the two standard types, it must be registered as a custom ink.

Calibration data

Calibration data is used to adjust the colors of the printer. After extended use, colors may shift from desired calibration. When this happens, use calibration data to make adjustments.
