[Tool] ChromIQ – a macOS and Windows GUI for ArgyllCMS printer profiling (v3.8.0)

[itsab1989]

Some of the targets he mentions are part of his Argyll Printer Profiler script:

I‘ll attach the other ones here.

thanks, at the moment busy at work, I will have a look later and report back.

The zip file was flawed somehow. This one should be better.

hi,

first thanks itsab for your great work ! I did test your tool yesterday and run into some issues I would like to report

1. printing from chromIQ with an canon pro1000 and the lates driver for Tahoe 26.5 does apply some unwanted corrections which look very much like a applied printer profile. PS has the same issue but printing from the canon print and layout software and print-tool works, in print-tool color matching is greyed out btw.

2. the guided refine process broken and selects wrong strips

Hi! Thanks four feedback!

For the printing issue: are you printing with the macOS printer dialog option or the the other built in print menu? You can change between those two in the settings window on macOS. It is pretty hard to nail this down. I tried back and forth to find a solution for this and for my Epson ET 8550 it seemed to work (I measured patches of a testchart I printed with different programms and in ChromIQ the results were the same). But I am not on Tahoe so maybe that can make a difference.

For the other issue: where did it go wrong exactly? Do you have the quality report saved? Which strips should it have flagged and which were actually flagged? Do you habe a screenshot or the log file maybe? This would help.

Edit:

This is Claudes take on issue 1 so far:

For Issue 1 (most useful first):

1. The Pro-1000 PPD + option list. Run and paste:


lpstat -p # to get the queue name

lpoptions -p <QUEUE> -l

1. and grab the PPD at /etc/cups/ppd/<QUEUE>.ppd. I want to see what Canon

calls its colour-matching / colour-correction option and its "off" value.

2. A captured "good" job. This is the gold standard. Put the queue on hold,

print a chart from Print-Tool (the working case), then inspect the spooled

job's options in /var/spool/cups/ (the c##### control file). That tells us

exactly which key=value Print-Tool sets that we're missing.

3. chromiq.log after a print using the native-dialog setting — it logs the

resolved printSettings and whether the no-CM lock verified, which tells me if

the PPD scan found Canon's option or not


Edit 2:

New update is on the way. It now pulls a few more strings to disable colormanagement that Claude considered useless before. I hope it helps. Please report back!
But for the guided refinement I have to know where it breaks exactly.

I'm a veteran regarding mac printing and profiling issues ;-) there is only one os print dialog available now in Tahoe but i made sure that i use the canon driver software and not the cups or AirPrint driver but there is an strange issue with banding (red colors only) with this driver too which does not occur with the canon print software which bypasses the os and communicates direct with the printer. will update the os tonight to 26.5.1 so maybe this solves some issues..

on the other point i will build more profiles next week and will report back.

Please do so! And also try the latest version of ChromIQ. I hope this will improve things as well.

Sorry for your inconveniences btw.
