Addressed various bugs from earlier 3.x versions, resulting in a more reliable profiling experience. Why 3.1.1 Was Significant
A wizard-driven interface for rapid monitor and projector calibration, ideal for standard office or studio setups. : Uses the i1Prism engine to optimize printer
While later versions (such as v3.7 or v3.8) exist, 3.1.1 is often sought after due to its stability in specific legacy environments or as part of the initial support phase for the i1Pro 3 Spectrophotometer .
| Area | Improvement | |-------|--------------| | | Faster chart measurement (up to 20% quicker with i1iO) | | Accuracy | Improved i1Pro 3 Plus spectral averaging for fluorescent papers | | UI | Fixed scaling issues on high-DPI Windows displays | | Stability | Resolved crashes when switching between display and printer modules | | Network | Better i1Share cloud profile upload reliability | Addressed various bugs from earlier 3
For those working with backlits or films, this version significantly improved scanning quality and reliability when using the i1Pro 3 PLUS Stability for CMYK+N Workflows: It addressed critical bugs where measurement reference workflows for multichannel data could not be saved. Why Calibrate at All?
It is important to note that color management software evolves rapidly to support new operating systems (like macOS Sonoma) and hardware. As of 2026, X-Rite has transitioned its color management solutions to . If you are looking for 3.1.1: It is considered legacy.
This typically means your macOS is too new for version 3.1.1. If you are on macOS Big Sur or higher, you must upgrade the software to a later version of i1Profiler (such as v3.5+) or switch to the Calibrite software ecosystem. The Transition: i1Profiler vs. Calibrite PRO Profiler
