What is this image and how does it perform such a calibration test?
It's an image I found on a site by a guy named Timo Autiokari. He has, unfortunately, shut his site down. What it does in layman's terms is mix dark and light colors in alternating bars that are very close together, so that the result should be the same as the actual color between them when mixed digitally. When the monitor is rendering the proper gamma (2.2 in the case of this chart) then the bars will appear substantially gray. Zoom in closely on it and you'll see the magic.
JPEG compression is a lossy process, with precisely the kind of information (high frequency, high contrast detail) this chart contains being mangled the worst, so it's no surprise it's showing up all colorful. You can also right click on the image above and save the original image (.png file).
Re: Astisan is working, but who know what is right?
Andrew, thanks. Like I said I was noticing peoples faces were a bit magenta compared to the cheap monitor (which looked ok -- though a different interpretation) -- so i'ts good to know the Artisan is still dead on. It's about five years with it, but I'm going to squeeze every last minute out of it! Every six months for last year I get all this popping and cracking which worries me, and then it goes away. Also, the patch, which worked great, seemed not to be working anymore, so I unistalled the full software/reinstalled, and finally got a calibration. So for now I'm still in business. I'm still using a custom profile that I think you helped with: (I think it was created to add a bit on contrast)
Final question:
I think my profile is 1.8, does this test which says 2.2 -- it that a big deal Noel/Andrew?.
Also, I do a right click save as on the test and I only get a png and it looks terrible.
Noel, what format do you have it in and maybe you can private mail it to me or I can give an e mail address here?
Ross, how did you even save it as a Tiff? I'm on a Mac and when I right click to save I don't seem to have any options other than the PNG that pops up.

Re: Astisan is working, but who know what is right?
Sounds like the difference between Apple and PC gamma (1.8 / 2.2).
My .png file is exactly what I uploaded for display above.
Are you viewing this forum via Safari? If so, all the color management is working and Safari is interpreting it properly for your system. By contrast, how are you displaying the .PNG file once you have saved it?
Re: Astisan is working, but who know what is right?
Noel, thanks, after I save it, I open it in Photoshop. I've saved it in various working spaced included adobe 1998, and it always looks horrid-- don't color manage, save to working space etc.
Interesting, I would never have thought of opening any image file in Safari, so I tried that, and it look, I think, about 95+ the same as your image looks in this forum. So that's the trick, save it open to Safari. But why am I having to open it in Safari? bit strange no?
BTW, so even if I'm in 1.8, the test bar, which says 2.2 below it, that's not a big deal or issue? the test should still work fine?
