The "i1Profiler 311" likely refers to a specific model or version of a color calibration device or software tool used in the field of color management for displays, printers, and other devices. i1Profiler is a software tool provided by X-Rite, a company known for its color management solutions. The "i1" prefix often relates to their i1 series of products, which include colorimeters and spectrophotometers used for calibrating and profiling displays, printers, and other color output devices.
Here's a general guide on using and understanding the i1Profiler software, particularly with a device like the i1iO (a colorimeter and display calibration device), assuming the "311" might refer to a specific device model or software version:
There is a growing concern about software phoning home. i1Profiler 311 is relatively safe.

i1Profiler 3.1.1 is a stable, feature-complete color management tool for legacy systems (Windows 10 / macOS Catalina) and older X‑Rite hardware. It lacks modern OS support and Apple Silicon optimization, making it unsuitable for current production environments. For new installations, Calibrite’s current software (version 4.x or later) is strongly advised. However, for users with a frozen hardware/OS setup, v3.1.1 remains a reliable choice.

Headline: X-Rite i1Profiler 3.1.1: A Critical Update for Stability and Compliance
X-Rite has rolled out i1Profiler v3.1.1, and while version number increments often suggest minor tweaks, this release addresses a crucial behind-the-scenes change that professional users need to be aware of.
The Headline Feature: macOS Notarization For users on macOS, this is the big one. With Apple tightening security protocols, the previous lack of full notarization was becoming a friction point for many workflows. i1Profiler 3.1.1 is now fully notarized with Apple. This means:
Key Improvements: Beyond the macOS security compliance, the update brings vital maintenance to the suite:
Why Update? If you are running an older version (especially v3.0 or earlier) on a modern Mac, this update is mandatory for stability. For Windows users, while not as critical regarding security pop-ups, the bug fixes regarding profile management make it a recommended upgrade to maintain a clean color management pipeline.
Recommendation: As always with color management software, ensure your existing license is current. The update is available directly through the X-Rite download portal or via the application's update checker.
Keep your ICC profiles clean and your displays accurate.

Version 3.1.1 introduced a refined uniformity correction routine. For video editors using dual or triple monitors, it automatically adjusts each display’s brightness and color temperature across 5x5 or 3x3 grid zones. This eliminates “hot spots” and color casting, ensuring that a pixel at the left edge of Monitor A matches the right edge of Monitor B.
If you shoot tethered (Capture One or Lightroom), you need your monitor to match your print lab. i1Profiler 311 allows you to create multiple monitor profiles for different lighting conditions (daylight studio vs. tungsten home office).
