Re: Measuring color casts in black and white prints

Lots of patience, less so of time.

The QTR-Create-ICC is a script that needs to have a valid measurement file with L*ab values from a 21 or 51 step target. Take a look at my post about how to use i1 profiler to create the measurment file and use the 51-step reference file included at the link at the end of the post, along with the 51 step target (just make sure you save the measurement file with an appropriate name to a relevant and easy to remember place on your computer). The instructions are captions on the images. I show running the linearize script, but it is the same for the create icc scripts.

Once the .txt measurement file is saved, just drag the "your_measurement_file-out.txt" onto the QTR-Create-ICC icon in the dock to run the script. That will graph the L*ab measurements and then spit out the ICC profile for you to drag to your colorsync profiles folder.

Hope that helps,
Richard Boutwell
