X-Rite have launched a new version of the i1Pro spectrophotometer, the i1Pro 3.
The device is included in the i1Photo Pro 3 package for creating custom camera, monitor, projector, scanner and RGB printer profiles.
Keith Cooper has been testing the new spectrophotometer for a while, and we’ll have a full review in due course.
Product information at X-Rite
The device and software is very similar to the i1Pro 3+ that Keith reviewed in detail a few months ago.

Three generations of i1Pro spectrophotometer.
The i1Pro 3 spectrophotometer has been launched by X-Rite. it features a number of hardware improvements over the old i1Pro2. Keith has been testing one for a while and whilst we’ll have a full review, it’s worth noting that the i1Profiler has been updated to support the new measurement device.
The software is very similar to that covered in detail in the following reviews/articles (newest first)

Ultimate colour accuracy for print perfectionists
NEW i1Photo Pro 3
i1Photo Pro 3 is the new standard of precision for “Colour Perfectionist” photographers looking for complete colour consistency throughout their workflow.
Quickly and easily create custom camera, monitor, projector, scanner and RGB printer profiles, ensuring the colours you capture, view and print are true.
i1Photo Pro 3 combines world-class hardware and software to deliver the ultimate professional-level colour management for photo pros who print, offering the most accurate and consistent colour calibration and profiling from capture to view to print.
Key Features
- New illuminant design offers full-spectrum LED light source, allowing for single-pass scanning and improves device reliability and accuracy
- Measure up to 5000 nits for correct calibration on high brightness displays
- Measures M0, M1, and M2 simultaneously in a single pass, cutting scanning time in half and reads smaller patches than the i1Pro 2
- Optical Brightener Compensation predicts what colours printed on optically brightened paper will look like under both standard and specific light conditions
- Real-time user feedback ensures accurate measurement position and a self-check tool to adjust and correct minor shifts
- XRGA (X-Rite Graphic Arts Standard) equipped to make it quicker and easier to adhere to ISO standards and have confidence that data sent or received is reliable and repeatable, reducing waste and rework
- Other new products in the i1Pro 3 range include the i1Basic Pro 3 and i1Publish Pro 3
