[Tool] ChromIQ – a macOS and Windows GUI for ArgyllCMS printer profiling (v3.0.0 beta 10)

Finger crossed: succesfully read the optimized target (with the previous profiles as preconditioning):

I really hope it is working. You have a really good hand for finding bugs by the way
It stresses me out everytime but I think we have fixed a good number already

But if you want to do pre-conditioning please update the app first. I see you are at 3.7.27 and the fixes were implemented later. Sorry for pushing so many updates btw.

Yes it works:

Now I have to see softproofing in PS using the initial profile (upper print) and the optimized profile (lower print):

Maybe a bit distorted, because the real world result here is way more neutral in the greys for the optimized profile (using the preconditioning method). The standard profile has a greenish glow (Epson ET-18100 NO grey ink only CcMmYK inks).

I am impressed. What I am actually doing now is a deluxe version of the Colormunki/i1Studio 50 + 50 patch method, but now I am using 336 patches for the initial profile/target and from the first reading it generates and estimates the neutral axis for which it generates new measure points to extrapolate and determine the final true neutral axis and corrects for the greys to be printed finally as good as possible to be truely neutral.

What do you use for the final targen command? I just printed a 506 patch set for my i1 Pro and will measure it tomorrow. I plan to do a three page patc set for the final profile (1518 patches) assuming I have no problems reading the one page at the 0.95 scale.

The preconditioning function in the manual option does not work. I tried 64 neutral steps in manual, but it does not appear in the targen window:

In the guided mode:

There is -n33 (neutral steps, I believe Sebastian uses this amount as standard). Unfortunately it not available in the manual mode, despite it I choosed -n64:

@itsab1989 :

I have discovered that the scanning of rows it does give an error when I reread the same row again: it presumes it is the next row, despite it has totally different patch layout. In command mode I often get the image: you have probably read row Y rather than X, do you want to proceed ? Is this known to you ? Not in the case with ChromeIQ: it just proceed when the right amount of patches is read, even if the row patch layout is totally different from the expected color values.
