[Tool] ChromIQ – a macOS and Windows GUI for ArgyllCMS printer profiling (v3.13.0-beta)

[itsab1989]

Ok i finally found the bug (unless your intent @itsab1989 was that)

all the settings in Chromiq Preferences panel that i change (for example in Chart Layout, font, size, offset and all the rest) are not applied at the chart i'm creating, i need to change the values, exit from Chromiq, relaunch it and now all the settings will be active, but if i need to change a value, i need to change it, exit Chromiq, start it again and now it works.

Hope it can help you to debug

Thanks for your detailed report. And sorry that I did not pay more attention to this before. At this very moment an update should be on GitHub that improves on this and now you should be able to apply changes to those settings without closing and restarting the app - clicking OK in the settings should be enough.

Edit: well give it 5 minutes to finish maybe

no worry @itsab1989 i suspect you have also a life over Chromiq

anyway thanks for your speed i will download as soon as i will be able to do

now it works perfectly, thanks again

i have another question what means this

We found that non-randomized charts can sometimes cause issues when measuring them and chartread might then not be able to reliably figure out in which direction a strip has been read or where one patch ends and the next one starts.
Randomization improves this quite a lot and should eliminate this error. However since it randomization is - well - random there is still a chance that you run into a combination where things might be a little difficult.
We try to take care of this so when you randomize it tries to figure out a good seed where it minimalises this risk but from a certain of patches you can‘t avoid a certain similarity anymore. However the most important thing is that two patches next to each other are not too similar and that each strip looks different from both directions. The warning it gives you also takes into account that for example strip B and AF have some similarity but in reality they should never mismatch because you have to read them in a strict order anyway.

Ok now i understood that, i would like to use always the same seed to create the profiles so i can then in case i need know from what chart i started

i have a lot of paper to profile (i bought a stock of several, about 50, different papers and about 12 rolls of paper that i need to profile) so using the same chart i can easily also figure how a paper will render some colors (or i hope to figure)

 

[itsab1989]

50? Really?

The funny thing is that Knut and I spent so much time developing this GUI, yet we don‘t really do much profiling ourselves. For my personal needs I have created 2 paper profiles - one for plain paper to try our the process and one for the photo paper that I like to use. And those were not even created with ChromIQ

But I hope that ChromIQ will make the process easier for. Then I would call it a success!

I've been a beta tester on this project from almost the beginning I have used Argyll to profile papers since 2008 and probably have profiled 30 different papers during this time. I don't do much profiling these days as I have settled on five papers that I really like and that are good for the type of prints I like to make. My suggestion is that you use the 1944 extended patch set that The Pharmacist developed. I compared profiles from that with the one I have been using since 2019 for Moab Entrada Natural. That profile was created using a preconditioning profile followed by a larger patch set generated from that. The Pharmacist patch set was in every way equial to the earlier one when I compared prints made using the two. I don't rely on soft proofing images to judge the profile as they are just too crude. The nice thing about the extended patch set is you don't have to print patches twice.

All my measurements were with an i1 Pro Rev D.
