Script for Printer Calibration on MacOS (free to use and modify)

[knowing]

Thank you for creating this script. I had an X-Rite i1 Studio (same device as the Colormunki) for a few years now and only ever used it for display calibration and profiling with DisplayCal as a GUI for Argyll.
I never got the printer calibration to work because the terminal commands for Argyll were a little bit too much for me to handle. But with your script I managed to create my first selfmade printer profile today.

For my first attempt I used menu option 1 and created a target from scratch. This worked perfectly fine.
My first issue was a bug in the ColorSync Utility. The option to print the image as a target is greyed out by default. A google search helped me to work around it. I had to go to the printers color settings and assign any color profile to the image. Then the ColorSync Utility allowed me to select the option to print it as a target. I printed the targets and let them dry. Then I tried to read the patches without any tool as a guide. This did not work very well. I got a lot of errors like "you probably read line AZ instead of A" or "too many patches recognized" or "not enough patches recognized" or "unexpectedly high deviation" (those weren't the exact words but it was somewhat similar). So this first attempt with 4 A4 sheets took me quite a long time and the result was not great.
But this was completely my fault because I wasn't used to handle the device properly.

For my second attempt I used the target you added in v 1.2.0 because you mentioned it in your release notes. I also remembered that a friend of mine 3D printed a guide for the i1 Studio for me. It is not the best quality but it made the reading process so much easier and faster and I got only a few error messages. The profile turned out pretty good.

The image on the top is printed with the default settings of my Epson ET8550, the middle one with the profile I got on my first try (better colors but posterization in the faces) and the one on the bottom is the final result. I am very happy with it. So thanks again!

Best regards

Awesome!

Thank you, itsab1989, for your feedback! You are the first to give some word about using the script. I really appreciate it!

Cheers,

Hi All,
I have again made major efforts to streamline the code and optimise usability in a new release of the Argyll_Printer_Profiler script (again, only Mac and Linux):

Overall: These changes significantly improve script reliability, user experience and maintainability.

1. Improved User Experience: Better menus and clearer feedback
2. Better Debugging: Daily logs with clear session separation
3. Cleaner Operation: Proper process cleanup and exit
4. Enhanced Reliability: Robust error handling and validation
5. Quality: More polished and maintainable codebase
6. Delta E Analysis Enhancement
   • Percentile Calculations: 99th, 98th, 95th, 90th percentile statistics
   • Patch Analysis: Count of patches below DE thresholds (1.0, 2.0, 3.0)
   • Range Statistics: Min/max values and range calculations
   • Outlier Identification: Enhanced delta E value processing
7. Tips on how to increase accuracy of a profile
8. ++

Hope there is less changes from now on, but feedback from one kind user (@itsab1989) gave some input to changes. Maybe someone could test on Linux? I do not have linux, so I "hope" everything works.

If anyone else would like to test, I would appreciate it. I have not found any comparable scripts for using ArgyllCMS like this one, so my hope is that many might appreciate it.

Cheers,
K
