Color Management

Overview

The CMS (Color Management System) Option Tool is an add-on software for the Xerox 490/980

Color Continuous Feed Printing System, and it can be installed on a remote PC. The CMS Option

Tool is the primary tool used when adjusting color on the Xerox 490/980 Color Continuous Feed

Printing System. Color selections and calibrations are performed using the CMS Tool. This section explains what the CMS Option tool is and how to make color selections for a specified job on the PC-GUI.

The Xerox 490/980 Color Continuous Feed Printing System produces what is commonly known in the industry as "Business" or "Transactional Color". This is one way to describe this caliber of color and where it fits in the market; between that of ink jet products and offset quality. The machine is also the fastest toner-based production color system available today. Utilizing four color housings, the machine outputs CMYK at 600dpi, and line screens from 85 to 300 lpi. Color output of this machine is richer in tone and hue than comparable ink jet systems. The color gamut is targeted at newsprint-type image quality.

Because the machine uses dry toner, it can print on a wide variety of substrates ranging from 64 gsm to 160 gsm. Paper weights lighter than 64 gsm may also be used subject to satisfactory testing for suitability. Light weight stocks are typically a problem for ink jet printers because the ink often causes water saturation, curling, and other issues. Through the use of dry toner and flash fusing technology, the machine provides a competitive advantage to the customer.

Because of its unique use of strobing xenon lamps, only the toner is heated and no pressure, heat or contact is made with the substrate itself. Therefore, the customer gains the ability to use light weight stocks and other special media, such as cards and adhesive labels, without any of the problems associated with the use of ink jet systems.

CMS Option Tool Overview

The CMS (Color Management System) optional tool is installed using GUI software added to the remote PC.

The CMS Option tool has the following features:

• Creating a color conversion table

• Creating a calibration table

You can use the CMS Option Tool to add paper color characteristics and CMYK ink characteristics. When adding characteristics, the printer will generate a color conversion table.

This table will be used and allow you to specify paper color characteristics or CMYK ink characteristics. You can add these selections when making job queue settings.

Over the course of time, the printer’s color characteristics are often altered during printing. The process to correct those color inconsistencies is called calibration. You can create a color correction table using the CMS Option Tool for calibration. If you have a duplex configuration, you can perform calibration on both printers.

Major Functions of the CMS Option Tool

The two major functions of the CMS Option tool is to generate calibration and color conversion tables.

Generating the calibration adjustment tables

• Printing Colorimetry patterns

• Creating calibration data

Generating the color conversion table

• Creating user definition paper data

• Creating user-specified ink characteristics data

• Viewing paper information

• 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

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.



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.

Using the CMS Option Tool

The CMS tool can be used for a variety of tasks. The most common task is printing a colorimetric pattern to be used for calibration. The following sections explain how to use the options on the CMS Option tool. Detailed instructions on how to perform calibration can be found in the later chapters of this guide.

Print Colorimetric Pattern

Use the Print Colorimetric Pattern tab to print a desired colorimetric pattern for use when performing calibration. Before you print a colorimetric pattern, you may have to login. Doubleclick the [Xerox 980 Color Continuous] and enter your username and password.

The colorimetric pattern print is used to calibrate the printing system. If you have a simplex configuration, a total of six copies will print of the colorimetric pattern will be printed. Three copies each of the Error Diffusion and three copies of the Halftone Dot will be printed. The name of each print will be printed along with the pattern print. If it is a simplex machine, the word “Upstream” will also be printed.

If you have a duplex configuration, a total of 12 prints will be printed. There will be three prints for each of the Error Diffusion and the Halftone dot for the Upstream printer and three each of the downstream printer. The name of the print (Error Diffusion or Halftone Dot) will be printed at the bottom of each pattern along with the words “Upstream” or “Downstream” to identify the printer.

Once the patterns are printed, select the best copy of each of the prints. You will need to cut out one print of each to be used for calibration. It is important when you cut the print that the lead edge is neatly and evenly trimmed.

8.

Place a piece of white paper on a table, then place the test pattern on top of the white piece of paper.

9.

Place the SIR on top of the test pattern. Ensure that the square cut outs are in line with the

100% color squares of the test pattern.

10. Using the provided Xerox 490/980 Color Continuous Feed Printing System SIR, evaluate by eye if the 100% square of colors on the test pattern are lighter or darker in density than the

Light shade or the Dark shade of the SIR. Repeat this procedure for each of the four colors

(Y/M/C/K). Write down the results of each observation for recording purposes.

100% SIR

11. Repeat steps 9 and 10 for each of the three test pattern print-outs.

12. Average the results from step 10 together.



Note

In order to change color density values, the system must be paused (in NOT READY mode) and the user must be logged in as a System Administrator. Once both of these requirements have been met, the color density values can be changed from the PC-UI by selecting [Printer Management] on the left-side navigation pane.

13. If the 100% color square on the test pattern (on average) is darker in density than the Dark color square on the SIR, lighten (decrease) the print density of that color by 1 using the PC-

UI.

14. If the 100% color square on the test pattern (on average) is lighter in density than the

Light color square on the SIR, darken (increase) the print density of that color by 1 using the PC-UI.

15. Select [Setting] after making the appropriate color density changes.

16. If another print-out of the test pattern is required, it may be released from the hold queue of the IOT-UI without resubmitting the job from the client station.

Note

In the following step, if any color density settings are at their maximum or minimum values, and the color settings are still not within the specified parameters of the SIR, notify your local Xerox service representive.

17. Repeat steps 8-16 as many times as is required until all four colors are within the specified parameters of the SIR.

18. When you are finished with this procedure, delete the job from the hold queue of the IOT-

UI.

Color Calibration

Using ColorPort

Utility Software

This chapter discusses how to perform Calibration. All processes that need to be performed before calibration are discussed in earlier chapters.

Calibration is when you check and adjust (by comparison with a standard print) the accuracy of the printed output. The Xerox 490/980 Color Continuous Feed Printing System uses the calibration process to ensure the best possible printed output.

To perform calibrations, you must have the CMS Option Tool loaded. Information on how to install the CMS Option tool is located in Chapter 2.

For calibration on the Xerox 490/980 Color Continuous Feed Printing System, it is recommended that you use the X-Rite Eye-One iSis spectrophotometer measuring device and the ColorPort

Utility Software. See Chapter 3

Download ColorPort Utility Software

for information on how to obtain the latest version of the ColorPort Utility Software.

Appendix

A

Logical Page Setting

The purpose of this appendix is to help you create imposition files in the pre-calibration and color calibration chapters of the Color Management Guide. The Logical Page Setting is one of the necessary properties that needs to be configured when creating an imposition file.

Note

This section is referenced as appropriate throughout the pre-calibration and color calibration chapters of this manual.

The Logical Page Setting is comprised of two sets of numerical values:

Offset Specification

The Offset Specification determines the positioning of the printed page on the paper.

Accordingly, the PC-UI requires the following two numerical values:

1.

X-direction, which determines how far away the printed page is from the outboard paper edge (on the imposition preview screen).

2.

Y-direction.

Logical Page Size

The Logical Page Size (or image area) tells the software what the printable area of the paper is.

Accordingly, the PC-UI requires the following two numerical values:

1.

Width.

2.

Height.

Printer Operator Guide A-1

Appendix Xerox 490/980 Color Continuous Feed Printing System

Offset Specification and Logical Page Size Explained

The two sets of numerical values that make up the Offset Specification and the Logical Page

Size are dependent on two variables:

1.

The DPI (dots per inch) selected in the imposition file, which can be either:

• 300x300 DPI or;

• 600x600 DPI

2.

The width of the logical page (image area) being printed.

Note

In the following paragraph, it mentions that a logical page size of 5.6 in (142 mm) by 12 in

(305 mm) is used. This is because 5.6 in (142 mm) by 12 in (305 mm) is the size of the test pattern printed to perform color calibration using the Xerox 490/980 Color Continuous Feed

Printing System SIR.

Later in this chapter, there is a

Table of Offset Specification and Logical Page Size Values . This table

shows the numerical values for the Offset Specification and Logical Page Size for widths of paper stock from 8.3 (211 mm) in to 19.5 in (495 mm) and a logical page size of 5.6 in (142 mm) by 12 in (305 mm).

If the width of the paper stock you are using is not covered in the Table of Offset Specification and

Logical Page Size Values

, use the sample procedure in the section Calculate Offset Specification and

Logical Page Size Values to determine the appropriate numerical values.

A-2 Printer Operator Guide

Xerox 490/980 Color Continuous Feed Printing System Appendix

Calculate Offset Specification and Logical Page Size Values

The following sample procedure uses the following hypothetical paper stock width, logical page size (image area) and DPI settings:

• Paper Stock Width: 8.3 in (457 mm)

• Logical Page Size (image area): 5.6 in (142 mm) x 12 in (305 mm)

• DPI: 300x300

To Calculate Logical Page Size Width

Multiply the width of the logical page size in inches by the DPI:

5.6 x 300 + 500 = 1680 = Logical Page Size Width

To Calculate Logical Page Size Height

Multiply the height of the logical page size in inches by the DPI:

12 x 300 = 3600 = Logical Page Size Height

To Calculate Offset Specification X-direction

1.

Multiply the width of the paper stock in inches by the DPI:

8.3 x 300 = 2490

2.

Divide the number calculated in the previous step by 2:

2490 / 2 = 1245

3.

Divide the Logical Page Size Width already calculated by 2:

1680 / 2 = 840

4.

Subtract the number calculated in step 2 by the number calculated in step 3:

1245 - 840 = 405 = Offset Specification X-direction

To Calculate Offset Specification Y-direction

This value is always equal to 0.

When finished with all calculations...

Add 500 dpi to the Logical Page Width:

1680 + 500 = 2180 = New Logical Page Width

Subtract 200 dpi from the Offset Specification X-direction:

405 - 200 = New Offset Specification X - direction

The Logical Page Settings should match the graphic below:
