OFFICE COLOUR
This section describes the features in the printer driver for “Office 
Colour” printer colour management.
There are two different sets of options in Office Colour: 
Although the Office Colour options contain controls for CMYK 
data, it is strongly recommended that you use the Graphic Pro 
options instead. If you are printing CMYK data, the Graphic Pro 
options provide more power and flexibility.
RGB OPTIONSCMYK OPTIONS

NOTE:
The options for CMYK data are not present in the Windows

support RGB colour data.

OFFICE COLOUR - RGB OPTIONS
Office Colour provides a collection of several different colour 
matching presets for RGB data.
These presets each change the colour of your print in a slightly 
different way.
These RGB colour matching options are available in all printer 
drivers.
PRESETEXPLANATION
Monitor (6500K) – 
AutoThe best colour match preset will be selected based on 
the type of document.
6500K - Perceptual will be selected if printing 
photographs. 6500K - Vivid will 
be selected if printing 
graphics and text.
Monitor (6500K) – 
PerceptualOptimized for printing photographs. Colours are 
printed with emphasis on saturation.
Monitor (6500K) – 
Vivid Optimized for printing photographs and for office 
graphics. The printer uses even more saturation than 
the Monitor (6500k) Perceptual setting.
Monitor (9300K)Colours are printed with emphasis on Lightness.
Use this setting if you are having problems achieving 
the correct colour when printing from Microsoft Office 
applications.
Digital Camera Optimized for printing photos taken with a digital  camera. Your results will  vary depending on the 
subject and the conditions under which the 
photograph was taken.
sRGBThe printer will try to reproduce the sRGB colour 
space. This may be useful if colour matching from an 
sRGB input device such as a scanner or digital camera.

CUSTOMISING RGB OFFICE COLOUR
WITH
 THE COLOUR CORRECT UTILITY (WINDOWS)
If the Office Colour presets are not sufficient for your needs, the 
Colour Correct utility provides a means of further adjustment. 
The Colour Correct utility provides two methods for adjusting the 
Office Colour settings:
1. You can adjust the overall appearance of the print by 
modifying Hue, Saturation and Gamma.
2. You can adjust the specific palette colours used in 
Microsoft Office applications. These adjustments only 
affect one specific palette colour at a time.
GRAPHIC PRO
This section describes the colour matching options available for 
Graphic Pro. 
The Graphic Pro colour matching system is based around ICC 
profiles. These profiles are down  loaded to the printer using the 
Profile Assistant utility and then  selected in the printer driver.

When a job is sent to the printer, the ICC profiles are applied to 
the print job on the printer.
WHAT CAN YOU DO WITH GRAPHIC PRO COLOUR MATCHING?
The Graphic Pro colour matching system is both powerful and 
flexible. Here are some examples of how the Graphic Pro colour 
matching system can be used:
MATCHING PRINTER COLOUR TO AN RGB INPUT DEVICE
By using the ICC profiles of a scanner, digital camera or monitor, 
the printers colour can be  matched to the input device.
PRINTER SIMULATION
Your printer can be used to simulate the colour output of another 
printer, even when printing RGB  documents. For best results, use 
CMYK documents when simulating  the colour output of other 
printers.
CMYK INK SIMULATION
Your printer can be used to simulate the colour output of a 
commercial printing press (SWOP, Euroscale or Japan Color 
inks).
MORE ACCURATE PRINTER COLOUR
If you have created your own prof iles with third-party ICC profile 
creation software, these can be download to the printer and used 
when printing.
NOTE:
Some features of Graphic Pro  colour matching can only be 
used if your printer is fitted wi th a hard disk. The printer hard 
disk is required if you wish to download and use your own ICC 
profiles to the printer.
The printer’s internal hard disk  is an optional accessory for 
some models.
If your printer does not have a  hard disk fitted, you will only 
be able to select th e factory default profiles that are built-in 
to the printer.

TYPES OF ICC PROFILE SUPPORTED
There are four classes of ICC profile supported by the Graphic Pro 
colour matching system:  
PROFILE TYPEDESCRIPTION
RGB Source
(RGB Input) These profiles describe the device that was used to capture 
RGB data (e.g. scanner or digital camera).
The RGB Input Profile may also be your monitor profile if 
you are trying to match to your screen.
CMYK 
Simulation
(CMYK input)These profiles describe the CMYK device whose colours you 
are trying to simulate. Typically this would be another 
manufacturers printer or an offset printing press.
Profiles are already built-in to
 the printer for commercial 
printing press inks such as SWOP or Euroscale.
Printer
(CMYK Output) This profile describes the colour characteristics of your own 
printer.
The printer already has factory default profiles built-in, but 
you can replace these profiles with your own if required.
Link ProfileThis is a special type of ICC profile that converts directly 
from CMYK to CMYK.
For example, a link profile could convert directly from the 
CMYK space of another printer to the CMYK space of your 
printer.

GRAPHIC PRO WORKFLOW – OVERVIEW
There are three steps to using the Graphic Pro colour matching 
system:
1.Gather or create ICC profiles (see below)
2. Download ICC profiles to the printer hard disk (page 59)
3. Select the ICC profiles in the  printer driver when printing 
(page 61)
STEP 1 - GATHER OR CREATE THE ICC PROFILES
Where can I get the profiles I need? 
STEP 2 - DOWN LOADING ICC PROFILES TO THE PRINTER HARD DISK
You can download profiles to the 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 – USB 
or Network (TCP/IP), and click [Start].
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 ProfileYou can create Link profiles using third-party ICC profile 
creation software.
Note that not all ICC profile creation software can create 
Link profiles.

If you know the Printer’s IP address, you can enter it 
manually.
3. The main screen of Profile Assistant 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.
(d) 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 Printer 
output profile.
(e) Select a number from 1 to 12. This number is used 
to identify the profile in the printer driver.
(f) Click [OK] to download the ICC profile to the printer.
