INTRODUCTION
This User Guide will assist you in using OptiCAL as
effectively as possible to achieve the goal of precise color
management and color matching.
Applications like Photoshop allow an image’s color
values to be adjusted. Your computer can recognize these
adjustments as profiles, and carry these instructions on to
the next device.
What you see on the monitor is most important, and is
determined by the monitor’s profile, which is referred to
by many applications, scanner software drivers, as well as
printer drivers.
The precision with which your monitor is calibrated and
its stored profile will determine the effectiveness of color
matching from input to application through output.
OptiCAL provides the user with a comprehensive selection
of software capabilities to perform the most precise calibration
of your monitor and create a system profile that will be the
cornerstone of your system's color management.
Before You Start ...
MINIMUM REQUIREMENTS
1. The recommended minimum setting
that the display resolution can be set to is
640 x 480.
2. The recommended minimum number
of colors that the display can be set to is 16
million colors (24-bit Color).
3. Video Card Support: Most video
cards that were made within the last two
years should be compatible with OptiCAL
software. To be absolutely sure, we have a
test program called OptiCheck that you can
download and run to test the video card on
your system. OptiCheck can be downloaded
from the software download pages of either
the ColorVision (www.colorvision.com) or
Pantone (www.pantone.com) Web sites.
Many manufacturers video cards support
OptiCAL for Windows 98, 98SE, ME, 2000
and XP. These include ATI, Matrox, GeForce,
Nvidia, plus many others that are not listed
here.
On an Apple Macintosh system, multiple
monitors are supported, and may be calibrated
and profiled. On a Windows system, multiple
monitors are not supported for calibration
and profiling. Therefore, if you have multiple
monitors on a Windows system, either by
using a dual head video card or by using
multiple video cards, only the primary
monitor will be calibrated and profiled.
In Windows, verify that you have set
your Hardware Acceleration to Full. This
can be found in the Setting->Advanced>Performance tab.
THINGS YOU SHOULD KNOW
BEFORE RUNNING OPTICAL
1. You should know how to change the
color settings using your monitors on-screen
controls. You need to know how to adjust the
color temperature, contrast and brightness
settings, and how to reset the monitor to its
factory defaults. If you are not familiar with
how your monitor works, please read the
manual for the monitor before you start to
calibrate with the OptiCAL software.
2. To accurately calibrate your monitor
there should be no light source shining
directly on the screen. Turn off all desk lamps
and close blinds to minimize ambient light.
If there is overhead lighting, try to shield
the screen using a hood. Some illumination
may of course be needed to see what you
are doing, so limit it to a small lamp behind
your monitor.
3. The Spyder should be plugged into
the USB port located at the back of the
computer, not into a USB hub or keyboard.
It is preferred with Windows PC's that the
Spyder be plugged into a separate PCI USB
card rather than into USB ports built into the
motherboard. Some combination USB/Fire
Wire cards have been known not work with
the ColorVision Spyder and OptiCAL.
4. If you have a graphics tablet or any
other non-essential USB device, web cam,
digital camera, external drives, they should
be unplugged during calibrations with the
Spyder.
2
5. Adaptec and Roxio CD Burning
software should NOT be running when
calibrating. Check if CD burning software is
on your list of StartUp Items to be sure
it is not running in the background. To
do this, press crtl-alt-delete to open Task
Manager and check if any of the following
programs/processes are listed as running:
easycd, directcd, createcd, adaptec, or roxio.
If one or more is listed, highlight the program
and click on the End Task button.
6.
When running the OptiCAL
calibration process, do not move the position
of the OptiCAL window on screen. When
you are changing the settings of your monitor,
wait until after the monitors on-screen control
window closes before taking readings with
the Spyder.
7. Once the calibration process is begun
and the Spyder is placed where indicated on
the monitor screen to begin taking readings,
do not remove the Spyder from the screen
until prompted to do so.
9. There are versions of OptiCAL for
Silicon Graphics (SGI) IRIX and Linux. See
Appendix 3.

4. In the Target box there are two pulldown selection dialogues, one titled Curves
and the second Whitepoint.
If you use Photoshop and your RGB
Working Space is set to Adobe RGB (1998)
recommended by Adobe for photographic
image work, or sRGB that is recommended
for work intended for the web, then selecting
Gamma 2.2 for the Target Curve and
6500K/D65 for the Target Whitepoint is the
appropriate setting because these working
spaces are based on those same settings.
On the other hand, if you use Photoshop
and your RGB Working Space is set to
ColorMatch RGB then select Gamma 1.8 and
5000K/D50 since this will set your monitor
to be most similar to that Working Space. If
you work in a pre-press environment, prepare
CMYK files for press output or view your
prints in a 5000K lightbooth then you should
also use Gamma 1.8 and 5000K/D50 for
your Calibration Target Settings.

Revised 12/13/02
USING PreCAL
PreCAL is not supported on LCD monitors, and should only be used with CRT monitors that support individual RGB
gain gun control.
BEFORE USING PreCAL
1. Once OptiCal is running you may
launch PreCAL from the OptiCAL window
File menu by clicking on PreCAL menu
option.
2. If your monitor has color temperature
presets, choose the setting that is closest to
the Target Whitepoint you have selected in
OptiCAL. In the PreCAL window, set the
Target Color Temperature menu to the same
value that you have selected in the Target
Whitepoint menu in OptiCAL.
What color temperature to choose:
also use Gamma 1.8 and 5000K/D50 for your
Calibration Target Settings.
When done click Continue.
3. Set the Contrast control on your
monitor to its maximum highest setting. After
you have done this, click Continue.
11
Revised 12/13/02
4. Adjust the brightness so that the logo
image is barely visible. After you have done
this, click Continue.
5. Attach the Spyder onto the screen
so that it covers the picture of the Spyder
in the window. After you have done this,
6. Adjust the monitor’s RGB gain
controls. If your monitor has Bias controls be
careful not to change them from the Factory
Default settings.
12
Revised 12/13/02
The objective is to get the three color
bars in PreCAL to be level, and obtain a
Difference value of less than 0.5 and a
Luminance value between 85 and 95.
If, for example, the Red bar is too
high then open the monitor's color controls
and reduce the Red Gain slightly. Close
the monitor's controls and then click the
Continue button to update the reading.
Continue this process until the Red, Green
and Blue bars are level. The small rectangular
target area will turn bold when you are close
enough.
When the three bars are level then the
Whitepoint is set correctly. If you reach
that point and then find that the Luminance
value is outside the 85-95 range you will
need to raise or lower all three Gain controls
simultaneously to adjust the luminance.
For example, if the Luminance is 80
then open the monitor's color controls and
increase the Red, Green and Blue Gain
controls slightly. Close the monitor's controls
and then click the Continue button to update
the reading. Continue this process until the
Luminance value is in the 85-95 range.
After adjusting the Luminance you may
find that you need to tweak the RGB Gain
controls individually to get them back to
being level and having a Difference of less
than 0.5 - it is a bit of a balancing act that
gets easier with practice. If you reach a
point where one of the RGB Gain controls
is set to maximum and you are still not able
to achieve a Luminance of at least 85 that
means that you have reached the maximum
Luminance that your monitor can produce,
assuming you have also set the Contrast
control to maximum.

Revised 12/13/02
USING TOOLS
1. OptiCAL Tools are accessed after
launching OptiCAL and its window is on
screen. From the Menu Bar click on Tools
and then select either Curves, Information
or Colorimeter.
CURVES WINDOW
2. The Curves window shows the output
brightness of the Input RGB. If you mark
the Target checkbox, it will show you the
target curve, that is, the desired response
curve. Marking the Uncalibrated checkbox
will show you the monitors RGB output
before calibration. Marking the Calibrated
checkbox will show you the values of your
latest calibration. The Calibrated curves will
closely match the Target curves. Calibrated
will only be available if you have used the
Profile or Validate commands from the File
menu. Marking the Correction checkbox
will show you the curves being downloaded
to the lookup table in the video card. Graph
Mode controls which RGB gun is shown.
Global displays all three guns. The red,
green and blue settings display the colors
separately. The Control Points allow you to
alter the tone response curves. To have the
Control Points available, you must check the
Control Points in the Curves Window in the
Preferences. You can change the number of
points depending on how specific you want
to make your adjustments.
INFORMATION WINDOW
3. The Information window shows information relating to the current
status of OptiCAL. The Display Luminance fields show the Black and
White Luminance Levels, in candelas per meter squared (cd/m 2 ), of the
monitor in its Uncalibrated and Calibrated states. The White Point (CIE x,
y) fields show the CIE x, y chromaticity coordinates for the Uncalibrated,
Target and Calibrated white point values. The
Uncalibrated chromaticity coordinates are taken from the last
calibration process. The Target chromaticity coordinates are the CIE x,
y coordinates of the currently selected Target Color Temperature. The
Calibrated chromaticity coordinates indicate the accuracy of the calibration,
relative to the Target White Point. The Phosphors (CIE x, y) fields show
the x, y chromaticity coordinates of the displays Red, Green and Blue
phosphors. The Delta E Color Temperature (Luv) fields show the measured
difference between the Target Color Temperature and the Calibrated Color
Temperature for the White and 50% Gray points of the monitor.

Revised 12/13/02
COLORIMETER WINDOW
4. The Colorimeter window allows you
to take individual measurements using the
Spyder. To select a color to measure double
click inside the square white window to open
the Windows Color dialogue.
5. Any RGB value, such as a color read
from a photographic image as RGB values
can be input to the Colorimeter by first
transferring the values into the Color dialogue
and then click OK. That color will be rendered
in the Colorimeter window.
6. Now place the Spyder within the
square of the Colorimeter window. The Take
Reading button initiates the use of the Spyder
or to perform a measurement or reading, and
updates the Color Space fields with the new
values. If the Take Reading button is disabled
(gray), then you need to click Calibrate
Sensor first. If Calibrate Sensor is disabled,
then you need to choose a sensor in the
Preferences dialogue. The RGB fields enable
the user to specify Red, Green and Blue
values to display a predetermined color in the
window. The Calibrate Sensor button resets
the calibration of the sensor, enabling the user
to manually initiate the sensor calibration
routine. The CIE XYZ, CIE xyY and CIE
Luv fields show the readings taken with the
sensor, translated into each of their respective
color spaces. The Kelvin field shows the
Color Temperature reading taken by the
sensor. The Luv value indicates how far
the measurement is from the Blackbody
Locus. The fL field indicates the luminance
reading taken with the sensor, measured in
footLamberts.

Revised 12/13/02
Appendix I: Calibrating Across Monitors
On a Windows system, multiple
monitors are not supported for calibration
and profiling. Therefore, if you have multiple
monitors on a Windows system, either by
using a dual head video card or by using
multiple video cards, only the primary
monitor will be calibrated and profiled.
Verify that you have set your Hardware
Acceleration to Full. This can be found in the
Setting->Advanced->Performance tab. The
goal is to get all monitors to be accurate, and
to choose a reasonable standard for them.
If you calibrate two different monitors
using the same white point and gamma
setting, then even though one may be a bit
sharper or clearer, both should display a file
with similar color.
For monitors that might be in very
different locations, such as a color correction
monitor in a low light, color corrected studio,
and the monitor upstairs in the editors bright
corner office, where those images are going
to be reviewed and selected, then using the
same standard might not even be best.
The color corrector may insist on having
their system calibrated to 5000k, while in
order to see colors on the editor's system;
they may need to be calibrated to 6500k. So
even though the settings are not identical,
for the situations in which they will be used,
they will give the most visually similar
results. In OptiCAL, you have the capability
to calibrate across monitors, but they have to
be the same type of screen either all LCDs
or CRTs.
5) Click "Yes" when you prompted
about saving luminance values. The Define
Luminance Dialog will open. Click "OK".
To calibrate across monitors, please
follow these steps:
6) Name and Save the Target file to a
floppy disk or a shared volume so that the
file can be accessed from other computers
that are to be calibrated.
1) Determine which monitor is the
weakest. Check each monitor by turning
the contrast control to maximum and then
measuring the uncorrected white luminance.
Calibrate this monitor first as described in
the following step. All other monitors will be
calibrated to match this one.
2) Set OptiCAL to Standard Mode in
the Preferences and then run the calibration
process. Once the measurement process is
complete, the correction will be applied to
the display and the application will return
to the main window. The "Target Display"
is now calibrated.
3) Save a Target File that describes
the calibration parameters of this "Target
Display" as described in the following steps.
This Target File will be used on all other
computers to calibrate their monitors.
4) Choose "Save Target As..." from the
File menu.
7) Go to the next computer to be
calibrated. Copy the Target File that you just
created into the "OptiCAL Targets" folder
on this computer.
8) Launch OptiCAL and set Precision
Mode in the Preferences. In the Target>Curve popup menu in the main OptiCAL
window select the Target File that you copied
into the "OptiCAL Targets" folder.
9) Optionally you can choose "Open
Target..." from the File menu and select
the Target File from some other location
(if you did not copy it into the "OptiCAL
Targets" folder.)
10) Initiate the Calibration process. Click
the Calibrate button in the main window.
11) Adjust the Brightness and Contrast
controls to match the Black and White Target
values from the Target file.
