The first part of this chapter describes the options available from the ColorWise color 
management system and explains how you can customize the color settings for your 
particular needs. It provides descriptions of the preset default settings of ColorWise 
and covers additional options for users who need to customize ColorWise.

Beginning on page 1-13 is a detailed explanation of what a PostScript Level 2 or 
PostScript 3 printer driver does, as well as information on the capabilities of various 
printer drivers and instructions for setting color options with the PostScript drivers for 
Windows NT 4.0, Windows 95/98, and Mac OS.

 

There are three ways to modify the Fiery X4’s printing behavior:

• You can select ColorWise options for an individual print job using menus that 

appear from the printer driver.

• You can select most ColorWise options as server defaults from Fiery X4 Setup or 

from the Control Panel, as described in the 

 

. These defaults will 

apply to all subsequent print jobs unless you override them.

• You can select some ColorWise options, particularly default 

 

 settings 

and calibration options, from ColorWise Pro Tools. These options include default 
Simulation Profile (see page 1-8), Simulation Method (see page 1-9), Appear in 
Driver as (see page 4-8), default Source Profile (see page 1-6), RGB Separation (see 
page 1-7), and associated calibration set (see page 3-3).

Applications can generate color data for the Fiery X4 in many different 

 

. 

The most common type of color data produced from office applications is RGB, while 
prepress applications generally produce CMYK data. Desktop applications can also 
generate spot colors such as PANTONE colors. To complicate matters, a single page 
may contain a mix of RGB, CMYK, and spot colors. The Fiery X4 lets users control 
the printing of these mixed-color documents with features that apply specifically to 
RGB, CMYK, or spot color data.

Fiery X4 color management generates CMYK data to be sent to the copier; additional 
processing may then be performed before printing begins. 

 

The diagram below illustrates the print options in the Fiery X4 color management 
process that affect color data conversions. You access these print options when you 
send a print job to the Fiery X4. Most of these options and settings are described in 
subsequent sections of this chapter.

RGB Source Profile is the only color option that applies strictly to RGB color data. 
The other options that affect RGB color also affect the more rarely used Lab, XYZ, and 
other calibrated color spaces.

 

For users who are familiar with PostScript 3.0 color, RGB Source Profile affects 

all CIEBasedABC color spaces (if the source space is RGB). Also, if you send CMYK 
data to the Fiery X4 in CIEBasedDEFG format, for example, by choosing PostScript 
Color Management in Adobe Photoshop, the Fiery X4’s Rendering Style selection—
which normally affects only RGB data—will also affect this CMYK data. 

 

Settings for the following options can be specified via print options when you send a 
job to the Fiery X4. Some can also be set as defaults by the administrator during 
Fiery X4 Setup. Settings specified via print options override the defaults.

 

85% Lightest to 115% Darkest

Performs a color adjustment on all 

 

 to make the printed output 

lighter or darker.

 

 

Photographic/Presentation/Relative 
Colorimetric/Absolute Colorimetric
(Default set at Setup)

Applies a Fiery X4 color rendering style (CRD) to RGB data (see page 1-5), or 
to any incoming data with a PostScript 

 

 definition, 

including CMYK.

 

EFIRGB/sRGB (PC)/Apple Standard/Other/
Source 1–10/None 
(Default set at Setup or with 
ColorWise Pro Tools) 

Applies an RGB source space definition to RGB data (see page 1-6). If you 
choose the Other setting, you can specify particular settings for gamma, 
phosphors, and white point. See the corresponding options in this table. This 
option, along with Gamma, Phosphors, and White Point, are the only 
ColorWise options that affect 

 

 DeviceRGB or calibrated RGB color spaces. 

 

1.0/1.2/1.4/1.6/1.8/2.0/2.2/2.4/2.6/2.8/3.0

Applies the specified 

 

 value to the RGB source space definition (see 

page 1-6). To use this print option, you must choose Other as the RGB Source 
setting.

 

Hitachi EBU/Hitachi-Ikegami/NTSC/
Radius Pivot/SMPTE/Trinitron

Applies the specified phosphor (monitor type) information to the RGB source 
space definition (see page 1-6). To use this print option, you must choose 
Other as the RGB Source setting.

5000 K (D50)/5500 K/6500 K (D65)/
7500 K/9300 K

Applies the specified white point value to the RGB source color space 
definition (see page 1-6). To use this print option, you must choose Other as 
the RGB Source setting.

Output/Simulation

Determines which CMYK color space your original RGB data will be 
separated into—CMYK for the copier (Output) or CMYK for a specified 
simulation (Simulation) (see page 1-7). It is important to note that when RGB 
Separation is set to Simulation, RGB colors are affected by CMYK Simulation 
Profile and CMYK Simulation Method.

SWOP-Coated/DIC/Euroscale/Simulation 
1–10/Match Copy/None 
(Default set at Setup or in 
ColorWise Pro Tools)

Adjusts CMYK color data to simulate an offset press standard or a custom 
color gamut defined at your site. Choosing None bypasses simulation (see 
page 1-8). 
N

: Some of the Simulation settings have slightly different names depending 

on the model of copier.

Detailed explanations of how these and other settings affect your print jobs are 
provided in subsequent sections of this chapter.

Quick/Full 
(Default set at Setup or in 
ColorWise Pro Tools)

Quick simulation applies one-dimensional transfer curves that adjust output 
density only. Full simulation applies colorimetric transformations that adjust 
hue as well as output density (see page 1-9).

default output profile/Output 1–10 
(Default set at Setup or in 
ColorWise Pro Tools)

The Output Profile is applied to all data in the print job (see page 1-9). User-
defined output profiles can be downloaded to the Fiery X4 with 
ColorWise Pro Tools (see Chapter 4).

On/Off 
(Default set at Setup)

The On setting optimizes the quality of black text and line art output (see 
page 1-10).

On/Off (Default set at Setup)

The On setting overprints black text placed on colored backgrounds; it 
automatically activates the Pure Black Text/Graphics option (see page 1-11).

On/Off 
(Default set at Setup or with 
ColorWise Pro Tools)

The On setting enables Fiery X4 matching of PANTONE colors; Off instructs 
the Fiery X4 to match color output to a Pantone-specified CMYK 
combination (see page 1-12).
