For large studios and prepress houses, i1Profiler 3.1.1 introduced more robust floating license management. This allows a network of computers to share a single i1 hardware device via the software, streamlining costs for multi-workstation environments.
Is it worth sticking with 3.1.1? Let’s compare.
| Feature | i1Profiler 3.1.1 | i1Profiler 4.0+ | | :--- | :--- | :--- | | Legacy Hardware Support | Full (i1Pro, i1Display 1 & 2) | Dropped support for pre-2015 devices | | UI Complexity | Simple, functional | Cluttered with cloud features | | HDR Monitoring | No | Yes (PQ and HLG curves) | | Video Card LUT loading | Manual | Automatic background loading | | Price | Free (if you have a license key) | Free upgrade, but forces hardware upgrade |
The Verdict: If you are using a modern i1Pro 3 or i1Display Studio, upgrade to version 4. However, if you own a legacy i1Pro or i1Display 2, i1Profiler 3.1.1 is the last viable version that will work reliably. I1profiler 3.1.1
Monitor profiling is simple; printer profiling is an art. Here is how version 3.1.1 excels at CMYK profiling.
Pro Tip for 3.1.1 users: Enable the "Profile Editing" module. If a specific gray balance is off, you can manually drag the Neutral Balance curve post-creation—a feature hidden in the "Expert Mode" toggle.
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). Cause: Windows Update overwrote the X-Rite USB driver
Why would a professional seek out this specific iteration? Here are the standout features that made the i1Profiler 3.1.1 release noteworthy.
Even a stable build has quirks. Here is how to solve the most frequent user complaints regarding i1Profiler 3.1.1.
Once installed, how do you actually use i1Profiler 3.1.1? Here is a basic monitor calibration workflow.
Step 1: Launch the Software Connect your i1Display Pro or i1Pro spectrophotometer. The software will auto-detect the serial number. Pro Tip for 3
Step 2: Select Your Workflow Click on the "Display" icon. You will see two options: Calibration (creates a LUT) and Profile (creates an ICC). Use the "Easy" wizard if you are new, or "Advanced" for version 3.1.1's custom grey balance controls.
Step 3: Configure Display Settings
Step 4: The Measurement Process Place the i1 device on your screen (use the counterweight if you have a laptop). Click "Start." Version 3.1.1 is notably faster than v2.x, usually finishing 100 patches in under 5 minutes.
Step 5: Save and Verify
Save the profile as a unique name (e.g., Dell_U2723QE_Jan2024). Use the "Verify" tool in i1Profiler 3.1.1 to generate a deltaE report. You want average dE < 1.0.
