Precise, consistent colormanagement requires accurate ICC-compliant profiles of all of yourcolor devices. For example, without an accurate scanner profile,a perfectly scanned image may appear incorrect in another program,simply due to any difference between the scanner and the programdisplaying the image. This misleading representation may cause youto make unnecessary, time-wasting, and potentially damaging “corrections”to an already satisfactory image. With an accurate profile, a programimporting the image can correct for any device differences and displaya scan’s actual colors.
A color management system uses the following kinds of profiles:
Describehow the monitor is currently reproducing color. This is the firstprofile you should create because viewing color accurately on your monitorallows for critical color decisions in the design process. If whatyou see on your monitor is not representative of the actual colorsin your document, you will not be able to maintain color consistency.
On your Mac, choose Apple menu System Preferences, click Displays, then click Color. Open the Color pane for me. Select a profile in the list on the left. If you have more than one display, assign a color profile using the Color pane that appears on each display. The color profiles can be easily activated by using the hotkey on the monitor next time without a PC or calibrators. Compatible with most calibrators The ASUS ProArt Calibration Technology is also compatible with the top major hardware calibrators such as X-rite i1 Display Pro and Datacolor Spyder 5 series.
Describewhat colors an input device is capable of capturing or scanning.If your digital camera offers a choice of profiles, Adobe recommendsthat you select Adobe RGB. Otherwise, usesRGB (which is the default for most cameras). Advanced users mayalso consider using different profiles for different light sources.For scanner profiles, some photographers create separate profilesfor each type or brand of film scanned on a scanner.
Describethe color space of output devices like desktop printers or a printingpress. The color management system uses output device profiles toproperly map the colors in a document to the colors within the gamut ofan output device’s color space. The output profile should also takeinto consideration specific printing conditions, such as the typeof paper and ink. For example, glossy paper is capable of displayinga different range of colors than matte paper.
Most printerdrivers come with built‑in color profiles. It’s a good idea to trythese profiles before you invest in custom profiles.
(Not applicable toPDFs) Define the specific RGB or CMYK color space of a document.By assigning, or tagging, a document with a profile, theapplication provides a definition of actual color appearances inthe document. For example, R=127, G=12, B=107 is just a set of numbersthat different devices will display differently. But when taggedwith the Adobe RGB color space, these numbersspecify an actual color or wavelength of light—in this case, a specificcolor of purple.
When color management is on, Adobe applicationsautomatically assign new documents a profile based on WorkingSpace options in the Color Settings dialog box.Documents without assigned profiles are known as untagged andcontain only raw color numbers. When working with untagged documents,Adobe applications use the current working space profile to displayand edit colors.
A. Profiles describe the color spaces of the input deviceand the document. B. Using the profiles’ descriptions,the color management system identifies the document’s actual colors. C. The monitor’sprofile tells the color management system how to translate the document’snumeric values to the monitor’s color space. D. Usingthe output device’s profile, the color management system translatesthe document’s numeric values to the color values of the outputdevice so the correct appearance of colors is printed.
Profiling software can bothcalibrate and characterize your monitor. Calibrating yourmonitor brings it into compliance with a predefined standard—forexample, adjusting your monitor so that it displays color usingthe graphics arts standard white point color temperature of 5000° K(Kelvin). Characterizing your monitor simply createsa profile that describes how the monitor is currently reproducing color.
Monitor calibration involves adjusting the following video settings:
The overall level and range, respectively, of display intensity.These parameters work just as they do on a television. A monitor calibrationutility helps you set an optimum brightness and contrast range for calibration.
The brightness of the midtone values. The values producedby a monitor from black to white are nonlinear—if you graph thevalues, they form a curve, not a straight line. Gamma defines thevalue of that curve halfway between black and white.

The substances that CRT monitors use to emit light. Different phosphorshave different color characteristics.
The color and intensity of the brightest white the monitorcan reproduce.
When you calibrate your monitor,you are adjusting it so it conforms to a known specification. Onceyour monitor is calibrated, the profiling utility lets you savea color profile. The profile describes the color behavior of themonitor—what colors can or cannot be displayed on the monitor andhow the numeric color values in an image must be converted so thatcolors are displayed accurately.

Make sure your monitor has been turned on for at least half an hour. This gives it sufficient time to warm up and produce more consistent output.
- Make sure your monitor is displaying thousands of colorsor more. Ideally, make sure it is displaying millions of colorsor 24‑bit or higher.
Remove colorful background patterns on your monitor desktop and set your desktop to display neutral grays. Busy patterns or bright colors surrounding a document interfere with accurate color perception.
- Do one of the following to calibrate and profile yourmonitor:
In Windows, installand use a monitor calibration utility.
In Mac OS, use the Calibrate utility, locatedon the System Preferences/Displays/Color tab.
For the best results, use third-party software andmeasuring devices. In general, using a measuring device such asa colorimeter along with software can create more accurate profilesbecause an instrument can measure the colors displayed on a monitorfar more accurately than the human eye.
Note:
Monitor performance changes and declines over time;recalibrate and profile your monitor every month or so. If you findit difficult or impossible to calibrate your monitor to a standard,it may be too old and faded.
Most profiling software automatically assigns the newprofile as the default monitor profile. For instructions on howto manually assign the monitor profile, refer to the Help systemfor your operating system.
Colorprofiles are often installed when a device is added to your system.The accuracy of these profiles (often called generic profiles or cannedprofiles) varies from manufacturer to manufacturer. You canalso obtain device profiles from your service provider, downloadprofiles from the web, or create custom profiles usingprofessional profiling equipment.
- In Windows, right-clicka profile and select Install Profile. Alternatively, copy the profilesinto the WINDOWSsystem32spooldriverscolor folder.
- In Mac OS, copy profiles into the /Library/ColorSync/Profilesfolder or the /Users/[username]/Library/ColorSync/Profilesfolder.
After installing color profiles, be sure to restart Adobeapplications.
You can embed a color profile in an object. Acrobat attaches the appropriate profile, as specified in the Convert Colors dialog box, to the selected objects in the PDF. For more information, see Color conversion and ink management (Acrobat Pro).

Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library. Then go to Preferences/com.apple.systempreferences.plist. Move the .plist to your desktop.

As a general rule of thumb, if Symantec Endpoint Encryption 11.1.2 has been certified for Mac OS X 10.12, it is also certified for 10.12 subsequent releases. It is not necessary to wait for a newer version of SEE 11.1.2 to use on a newer version of Mac OS X 10.12 as long as the version supports the base release of Mac OS X. For more information, see article.TIP For SEE 11: For Mac OS X System Requirements for Symantec Endpoint Encryption 11, see article. Mac systems which have 4K Native drives.

If the application is the same, return the .plist to where you got it from, overwriting the newer one.
