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

[mavtop]

Using the ChromIQ patch generator I suggest 8 mm minimum for the i1Pro1. The i1Pro2 can deal with 7.5 mm or even smaller, but 8 mm should be ok for the older i1Pro1

now i moved the top margin to 20 and changed character, is there a way to reduce the Font dimension, i didn't catch

OK thanks for the update, I will start from scratch using a totally different target. I think all the testing have messed up the files here

You mean the size of the strip label text? This can be adjusted in the settings - 3rd tab.
And I don’t understand what you mean with „changed character“. Do you maybe have a screenshot?

OK, with a totally new workflow and new target:

finally success according to this:

But where is the target ??? I cannot find it in the workflow directory.

@pharmacist
It says it should be at: DDownloads\ChromIQ_scanner_target_480-p1s1-scanner.icc

 

[pharmacist]

ahh ok, very strange place to look at

Anyhow, not sure what I am doing wrong, as the version I made with Eye-One Match (old i1Pro1) I got this:

Which is perfectly ok, but when loading the ChromIQ version I got nothing to see (something vague shadows):

I will test your latest version and try again.

 

[itsab1989]

If it goes wrong again please attach the files and maybe the logfile

 

[pharmacist]

Yes it works now: I have turned the green mesh up-side-down and now it is perfect:

 

[itsab1989]

Nice! But it seems there was still some guessing involved and the program should have giving you a hint instead of letting you create a wrong profile…
Claude is currently still busy with Knuts request then maybe we can figure something out. Could you attach the files you used for this one so I have something to try it with myself?
