[Tool] ChromIQ – a macOS and Windows GUI for ArgyllCMS printer profiling (v4.0.0)

This is a little emarrasing now but yesterday I discovered this repo on Github by accident:

https://github.com/QiuJueqin/Yet-Another-Color-Gamut-Visualizer

And since I liked the animated gifs and it was somewhat related to to ChromIQ I challenged Claude to create a nice GUI around it in the ChromIQ style and think of options that might be useful for such a gamut viewer. Some hings I requested on my own. I don’t know if this makes sense at all and have not even tried it once myself. But on the plus side it looks nice I think :D

Here is Claudes take on this:

Is Claude also taking into account to read version 4 ICC profiles ? I am not sure if ChromIQ can write version 4 profiles (I did not check this), but maybe this would be nice.
 
For ChromIQ in the beta settings there is a profile building engine. That should be able to write ICC v4 but I have not tested this at all and left it disabled because of this. Might be completely bad.

The gamut viewer did not support v4 yet but since you asked I am adding it now

@itsab1989 : Delayed happy birthday Sebastian!

I've been following this thread with huge interest since Epson stopped producing cartridges for my old but beloved Epson R1900 and I switched to Marrutt refillable cartridges. Hence, the Epson profiles no longer work accurately enough and I need to profile my printer. After some dabbling around with Vuescan (which claims to be able to profile a printer with my scanner but I can't get that to work) and cProfiler (Argyll-based), which seems to correct the wrong way since its for input devices, I decided to go Argyll, but was reluctant because of the lack of GUI. Then I discovered this thread and your (fantastic!) efforts on ChromIQ, so I want to try it, but have the following questions:

1. I do not have much cash so am reluctant to shell out for a proper spectrophotometer (Xrite and the like) since they are very expensive. My flatbed scanner (Epson V30 Photo, not (yet) calibrated) seems to rather accurately scan my ColorChecker passport, at least visually on my calibrated monitors, which is sufficient for my purposes. Is it possible to, for now at least, print a target, scan it with my scanner, and use that (TIFF) file to generate a profile with ChromIQ? I realize that it is not ideal, and that a dedicated spectrophotometer is a (much) better solution, but it should at least get me in the ballpark, and could perhaps be sufficient for my purposes. I also think that for many (less professional/picky) users, this could be a sufficiently good solution that is convenient and fast. If it does not seem accurate enough, the next step would be to purchase a dedicated spectrometer of course, but I have the feeling that using my scanner for now might suffice for my requirements.

2. I read about a cheap Chinese spectrophotometer (CR30) which is a fraction of the cost of an Xrite version, and folks seem to like it. Would this be an alternative route and would it work with ChromIQ?

Yes, I realize that these are simple questions and perhaps can be considered cheap skating, but alas, not all of us have the stringent requirements of a perfect profile, nor perhaps have the cash to purchase a dedicated Xrite device for what for many is a hobby, while a much larger user-base could be reached if more cost-efficient solutions would be available and/or at least enabled by ChromIQ, which in itself seems an ideal approach.

Thanks very much in advance for your thoughts and for taking the initiative to create a UI for ArgyllCMS!
