monitor calibration and profilingi1 Profiler
Monitor Calibration/Profiling

Part of X-Rite's new colour management software

X-Rite has recently released version 1.0 of their new application i1 Profiler.

It's been widely trailed since last year, and has appeared at several trade shows.

Keith has been testing it for a while, and in due course will have more detailed looks at different aspects of its use.

This article looks at its monitor calibration/profiling capabilities, using the i1 Pro spectrophotometer.

Other functionality is listed at our i1 Profiler main page, where we'll include links to other reviews and any useful resources we come across.

June 2011 - this software now supports the new i1 Display Pro hardware and has been updated to Version 1.1.1
December 2011 - V1.2 Additional ADC and profiling support - Full list of updates

... or try at Adorama

The examples that will be shown are using Apple Macs, but the software generally works in the same way on Windows machines (Win7 is supported).

i1 profiler for monitor profiling

I'm going to assume that if you've got this software, you're pretty serious about colour management.

If you're new to it all, I've written quite a few more introductory articles and reviews that explain -why- you might choose different options, as opposed to pointing out details of functionality

See our Monitor setup page for links to more general information.

The software supports multiple monitor systems and measurement with the i1 Pro spectrophotometer or i1Display Pro (right)

Note that it does not support the i1Display 2 colorimeter or the ColorMunki.

Features (from X-Rite)

Projector profiling is not supported in the basic version of the i1 Profiler package. I'll look at this aspect of the software in a future article.

If you plug in your i1 spectro, it can act as an activation 'dongle' for the software.

The green ticks show the activated modules.

Printer and projector profiling are not enabled. The ColorChecker Proof option is enabled (see the RGB Print profiling page for more on this)

The basic mode of operation of the software, offers simplified interfaces and options.

This is also where you can update your license and register the product.

Given that I originally did this with a Beta version of the software, I can't comment on how easy the process will be, but you do have the option of both on and off-line registration and upgrades.

basic monitor workflow

There are 'help notes' in the left side panel, or you can access more detailed help (and videos) from the home page.

Note the little icons, in the left bottom corner. One expands the screen to full size, whilst the other takes you back to the startup or Home screen.

In the main screen area you can see that I've two monitors attached, and a brightness of 120cd/m2 is selected with a D65 whitepoint.

The screen also shows another important aspect of the design of i1 Profiler - Workflows.

Almost anything you do has a sequence of large icons in the workflow panel - these show where you are in a sequence of steps. Workflows can be saved, and you can jump into them at any point, if the appropriate data is available (a set of measurements for example)

For monitor calibration/profiling, I'm using the i1 Pro, which needs calibrating.

A set of coloured patches will fill the screen, whilst the device measures what light is actually coming from your screen.

Note that V1.1.1 of the software adds the following features

A full screen view appears before the first stages of calibration - the graphic shows how to place your particular measuring device.

screen calibration - i1Display pro and macbook pro

luminance checkDuring the first stage of the measurement process, the brightness of your screen is measured and compared to what is desired.

With the screen I was using, you have to adjust this manually, but the software will set the brightness level itself, if the display supports it.

It takes a few minutes for the measuring process to run.

After the measurements are completed, the measured values of the target are shown alongside what they should be.

You can save these measurements if wanted.

Note the left/right arrows under the display - this moves you in to the next stage where the profile is built.

measured screen values

I'll give the profile a name at this point.

I'm testing on a Mac, so I get the choice of whether to put the profile into my user settings, or system settings - since I'm the only person using the computer, I use system-wide settings for all my profiles.

Normally the default profile name is just fine, but with various testing work that I do, I want to know what profile is from what software.

There are a whole load of test images available to look at in before/after fashion.

All the screen shots above were in the 'Basic' mode.

Switching to 'Advanced' gives many more options, and also shows the Assets panel.

Assets are the name given to any set of data that you might use or create in the process of using the software.

On slight thing to note - this software has a distinct 'Not Invented Here' attitude to profiles not created by it, so those four profiles you see listed are four amongst the 20 or so that currently clutter up my monitor profiles directory (I've some related reviews I'm finishing off in this respect)

monitor profiling - advanced mode

As you can see, there are more detailed options for many calibration/profiling settings.

You can save your chosen settings as an 'Asset' too.

Move your mouse over the image below to see more options.

There are a number of ways of looking at the resulting profile, as well as the before/after photos shown above.

Move your mouse over the image to see a graph...

The real world utility of these graphs and displays is perhaps debateable - the OSX ColorSync Utility shows a lot more details for example.

Of more use are the results of profile evaluation, where the profile results are compared to a target set, providing numerical data on the quality of the profile, although perhaps of more use over time for showing if you monitor is starting to fail.

Purchase From B&H (also helps us)

I'll have to admit that although I've used ProfileMaker Pro for several years, I've never used its monitor profiling capabilities.

The lack of support for the i1 Display 2 colorimeter strikes me as odd, since there is a school of thought that favours colorimeters over spectrophotometers at low screen brightnesses.

(Explained when the i1 Display Pro appeared in June 2011)

If you've an unusual set of profiling requirements then it's useful to be able to save preset values as an 'Asset'

The profiles and calibration produced on screens here were just fine for our Apple CinemaHD display and a second monitor I use for palettes and the like.

I also tested the profiling on an NEC SVR271 display - a very high spec 27" display.

Here, the profiling was fine, but didn't make any use of the monitor's hardware LUT adjustment.

Then again, if you're spending £1500 on a monitor like that, you'll be using more specialist software to set it up, and probably not an i1 Pro to calibrate/profile it.

I find some aspects of the profiler user interface a little quirky (on a Mac), but that's more of an issue when it comes to printer profiling and I'll leave a discussion until then.

So, overall it works quickly and simply and calibrates/profiles your monitor.

Projector profiling is an additional feature that you don't get in the 'Basic' package, so I'll also address that elsewhere.
