Graphic Pro Workflow – overview
There are three steps to using the Graphic Pro color 
matching system:  
1. Gather or create ICC profiles (see below)
2. Download ICC profiles to the printer hard disk 
(page 222 )
3. Select the ICC profiles in the  printer driver when printing 
( page 223 )
Step 1 - Gather or create the ICC profiles
Where can I get the profiles I need?  
     
Profile typeWhere to get profiles
RGB Source
(RGB Input) Obtain your RGB source profiles from your scanner, 
camera or monitor manufacturer.
CMYK 
Simulation
(CMYK input) Obtain the simulation profile from the manufacturer of the 
printer you wish to simulate.
Printer
(CMYK Output) The factory default profiles for your printer are built-in. If 
you need greater accuracy, you should create your own 
printer profile using third-party ICC profile creation 
software.
Link Profile You can create Link profiles using third-party ICC profile  creation software.
Note that not all ICC profile creation software can create 
Link profiles.

Step 2 - Downloading ICC pr ofiles to the printer hard 
disk
You can download profiles to th e printer hard disk using the 
Profile Assistant utility.  
Using Profile Assistant
1. Launch Profile Assistant  
2. Select a printer
If this is the first time you have used Profile Assistant, you 
should allow the utility to search for compatible printers. 
Select the connection types that you wish to search – 
Parallel, USB or Network (TCP/IP), and click [Start].
If you know the Printer’s IP address, you can enter it 
manually.
3. The main screen of Profile A ssistant displays the profiles 
resident on the selected printer’s hard disk. To download 
a new profile to the printer:
a. Click [Add].
b. Select an ICC profile from your computers hard disk. c. Once you have selected a profile, you can add it to  the printer as one of the 4 profile types - RGB Source, 
CMYK Simulation, Printer or Linked.
The options available will depend on which ICC profile you 
have selected. For example, if you have selected a CMYK 
profile, you may only be able to  add this to the printer as 
a CMYK Simulation or Pr inter output profile.
d. Select a number from 1 to 12. This number is used to  identify the profile in the printer driver.  
e. Click [OK] to download the ICC profile to the printer.

Step 3 - Select ICC prof iles in the printer driver
What you select in the printe r driver depends on the color 
matching task that you wish to perform.
Examples of selecting ICC profile s for different color matching 
tasks are shown in the next sections of this guide.
Matching the color of a monitor, scanner or camera
The Graphic Pro color matching system can be used to match 
the printer color to an RGB input device such as a monitor, 
scanner or digital camera.
      graphicpro-RGBmatch.jpg    
1.RGB data
2. Printed document
3. RGB source profile
4. Scanner, monitor, camera, etc.
5. Printer output profile
6. Leave on Auto or select your custom profile.
To match an RGB input device, first download the RGB source 
profile and printer profile (optional) to the printer hard disk 
using Profile Assistant.  See “Using Profile Assistant” on 
page 222.   
Once the profile(s) have been downloaded, make the 
appropriate selections in the printer driver. These are 
described in the next section (Windows  page 224, Mac OS 9 
page 225 . Mac OS X  page 226).

Windows
This information applies to th e Windows PCL and PostScript 
drivers.  
1. To match the color of an input RGB device such as a 
monitor, scanner or digital camera, make the following 
selections in the printer driver:
2. On the printer driver [Color]  tab, select [Graphic Pro]  
and click [Options].    
3. Select [ICC Profile color Matching].
4. Select the ICC profile that corresponds to the device you 
are trying to match such as your monitor, scanner or 
digital camera.
Remember that the names “RGB Source 1”, “RGB 
Source  2” and so on relate to the number assigned to the 
profile using Profile Assistant.  See “Using Profile 
Assistant” on page 222.
5. Select a Printer Output Profile.
If [Auto] is selected, the factory default profiles that are 
embedded in the printer will be  used. If you have created 
a printer profile yourself using profile creation software, 
select it here.
Tip—If you have selected your  own printer output profile, 
you will also be able to adjust the rendering intent.

Simulating another printer – RGB source data
The Graphic Pro color matching system can be used to 
simulate the color output of another printer.
    graphicpro-RGBmatch.    
1.RGB data
2. Printed document
3. RGB source profile
4. Scanner, monitor, camera, etc.
5. Printer output profile
6. Leave on Auto or select your custom profile.
    
Important!   Be aware that if the device you are trying to 
simulate has different color capabi lities from your own printer, 
exact color simulation will not be possible. For example, it may 
be difficult to reproduce the exact  colors of an inkjet printer on 
a toner-based printer.
Additionally, differences in the range of printable colors 
between different devices can make simulation using RGB 
source data inaccurate. To achieve best results when simulating 
the color output of ot her printers, you are strongly advised to 
use CMYK data as a source. See “CMYK ink simulations – CMYK 
source data” on page 231.  
To simulate the output of another printer, you need to 
download at least 2 profiles to your printer using Profile 
Assistant:
•RGB Source Profile
• Simulation Target Profile
• Printer Output Profile (optional)
Once the profile(s) have been downloaded, make the 
appropriate selections in the printer driver. These are 
described in the next section (Windows  page 228, Mac OS 9 
page 229 , Mac OS X  page 230).

Windows
This information applies to the Windows PCL 5c, PCL 6 and 
PostScript drivers.  
If you are using a source RGB document, simulate the output 
of another printer by making th e following selections in the 
printer driver:
1. On the printer driver [Color]  tab, select [Graphic Pro] 
and click [Options].    
2. Select [Printer Simulation].
3. Select the ICC profile that  corresponds to the device 
used to capture or display your source document - this 
could be a monitor, scanner or digital camera.
Remember that the names “RGB Source 1”, “RGB 
Source  2” and so on relate to the number assigned to the 
profile using Profile Assistant.  See “Using Profile

4. Select a Simulation Target Profile.
This profile corresponds to the printer you want to 
simulate.
If you wish to produce black and gray colors that are 
printed using only black to ner, enable the [Preserve 
Black] option. Although this produces a better quality 
print, the black and gray colors will not be simulated 
accurately.
5. Select your printe r output profile.
If [Auto] is selected, the factory default profiles that are 
embedded in the printer will be  used. If you have created 
a printer profile yourself using profile creation software,
