For the uninitiated, i1Profiler is the professional-grade software engine that drives X-Rite’s i1 series of hardware colorimeters and spectrophotometers (such as the i1Basic Pro 3, i1Display Pro, and i1Studio). While operating system level adjustments exist, they lack the nuance of a dedicated hardware/software solution. i1Profiler allows users to create custom ICC profiles for monitors, projectors, scanners, and RGB/CMYK printers.
Version 3.1.1, specifically, sits in a sweet spot of the software’s evolution. It bridges the gap between legacy hardware support and modern display technologies like HDR and wide-gamut monitors (AdobeRGB, DCI-P3, Rec.2020).
One of the most valuable additions in this build was the Quality Assurance module. Instead of just creating a profile, i1Profiler 3.1.1 allows you to run a diagnostic check on your monitor’s hardware. It measures uniformity, luminance decay, and color gamut coverage (sRGB, AdobeRGB, DCI-P3). This is crucial for video editors who need to ensure their display hasn’t drifted mid-project.
| Aspect | Rating (1–5) | |--------|---------------| | Accuracy | ⭐⭐⭐⭐⭐ | | Stability | ⭐⭐⭐⭐ (fewer crashes than 3.0) | | UI/UX | ⭐⭐⭐ (dated but usable) | | Speed | ⭐⭐⭐ (slow printer chart reading) | | Documentation | ⭐⭐⭐ (technical, not friendly) | | Value | ⭐⭐⭐⭐ (free with hardware) |
Overall: 4/5 — Still the professional standard for i1 hardware. If you already own an i1 device, there’s no reason not to use 3.1.1. If you’re on newer macOS (Ventura/Sonoma) or Windows 11, it works fine. For an overhaul in UI/speed, you’d need i1Profiler 4.x (released later).

, X-Rite (and the Calibrite ecosystem) has introduced a vital maintenance update designed to streamline your color management workflow and ensure your hardware communicates flawlessly with the latest operating systems.
If you are using an i1Display Pro, i1Pro 2, or the newer i1Pro 3 family, this update is a must-install. Seamless Hardware Support
The standout feature of version 3.1.1 is the refined support for the i1Pro 3 Plus
spectrophotometers. These devices are the industry standard for high-brightness displays and large-format printing. This update ensures that the automated scanning functions are smoother and that the inter-instrument agreement—the "closeness" of readings between two different devices—remains tighter than ever. Key Enhancements and Fixes
While version 3.1.1 focuses heavily on stability, several "under the hood" improvements make a noticeable difference in daily use: OS Compatibility:
Improved stability for the latest builds of Windows 10/11 and macOS. This addresses common "device not found" errors that occasionally plagued older versions during system sleep cycles. Monitor Optimization:
Enhanced handling of high-bit depth panels and HDR-capable displays, ensuring that the profiling process accounts for the wider gamuts found in modern creative monitors. Workflow UI:
Minor tweaks to the user interface to make the transition between "Basic" and "Advanced" modes more intuitive, particularly when generating printer profiles. Bug Squashing:
Critical fixes for data export, ensuring your ICC profiles are saved with correct metadata for use in Adobe Creative Cloud and other professional suites. Why You Should Update Now
In the world of color management, software is the bridge between your hardware’s "eyes" and your computer’s "brain." Using outdated software like 3.0.x can lead to slight color shifts or software crashes during long printer-patch scanning sessions.
Updating to 3.1.1 ensures that when you print that portfolio or deliver a digital campaign, the colors you see on your screen are exactly what the client receives. How to Get Started Always save your current custom profiles before updating.
Visit the official Calibrite or X-Rite support page to grab the 3.1.1 installer. Calibrate:
Once installed, perform a fresh calibration of your primary display to take advantage of the updated algorithms. Stay calibrated, stay accurate. or how to set up an Advanced printer profile using this version?
Print profiling is notoriously time-consuming. Version 3.1.1 refined the patch algorithm, reducing the number of color patches required for a high-quality printer profile by up to 30% without sacrificing accuracy. This uses a "Dynamic Patch Generation" system that analyzes the printer’s initial response and skips redundant color measurements.
