Matrix profiles are created using algorithms based on ma-
trices and linearization curves.
✦
LUT-Profiles (or Table Profiles) are created using lookup
tables.
LUT-Profiles are a perfect match for devices that don’t respond
in a linear way such as printers or some older monitors. Though
LUT-Profiles are more precise and may give better results, es-
pecially for nonlinear displays, they are not recommended in
workflows using Adobe Software (especially Photoshop) as they
are not fully compatible with it. Matrix profiles on the other hand
are the best choice for high quality monitors such as Series
300/500/700 due to their linear response even if they may not
be as accurate as LUT profiles. Matrix profiles give smoother
results with Adobe Photoshop.
Though both profiles types rely on different calculation tech-
niques, they generally don’t provide significantly different results
on Series 300/500/700 monitors. We therefore recommend the
use of LUT or Matrix depending on your workflow and the soft-
ware used.
5.4.5. Profile Version
By default, profiles created with Blue eye pro are ICC 2 pro-
files. If required you can choose version 4 profiles by marking
the
ICC 4
button. Though ICC2 profiles have been widely used
and proved their reliability, improvements needed to be added
in ICC4 profiles to increase predictability and performance and
to reduce eventual differences of interpretation. ICC4 profiles
provide:
✦
A more precise definition of rendering intents to reduce am-
biguities.
✦
Embedded chromatic adaptation information.
✦
Improved look up table (LUT) specifications.
✦
Improved translation from PCS XYZ to PCS L*a*b*.
Both profiles versions will provide excellent results in your work-
flow. Though ICC4 profiles are newer and integrate several im-
provements, they might not be supported by every CMM.. We
therefore recommend the use of ICC4 or ICC2 profiles depend-
ing on your workflow and the software used.
5.4.6. OSD lock
Use this option to prevent accidental changes to your monitor’s
settings that may invalidate your calibration. Mark the
Locked
button to lock the on-screen display (OSD), Mark the
Unlocked
button to allow changes. Once your advanced options are mod-
ified, you can:
✦
Go back to the main menu by clicking on the
Main menu
button
✦
Go to the Settings window by clicking on
Settings
✦
Click the
Calibration
button in order to calibrate your
monitor.
5.4.7. ColorKeeper
ColorKeeper is LaCie’s hardware backlight stabilizer technology,
present in some (but not all) LaCie displays. Selecting or de-
selecting the checkbox respectively activates or deactivates the
backlight stabilizer. When used on a display that doesn’t embed
ColorKeeper, this option is grayed. On the LaCie 700 Series, to
ensure maximum color precision and stability, ColorKeeper is on
by default and cannot be turned off.
