OK here you are: I have 2 sets one for the 228-patch target and one for 247-target, so you can have a look at both The idea is that the python script can be extended to any desired patch size and if possible that a randomized patch order is also converted correctly. At this moment the script...

Great to see you guys stepping in to help each other with their own specific knowledge in order for the greater good. Despite the incredible possibilities of ArgyllCMS it still remains a bit cryptic and an graphical user system that is easier to use than the previous attempts were still a bit...

OK, I just generated a larger patch set target for the Colorimeter to be printed on 2 sheets of A4. It has twice amount of patches compared to the previous 247 patch target.

@x64 : You were right the randomisation was the cause of the hanging of the colprof process. I now have changed the patch layout to be non-randomized, but in doing so the grey ramp is sometimes difficult to determine where the next grey patch starts. To visually overcome this I have introduced a...

OK, now I understand the underlying problem. I will regenerate the the ti2 not the use random order and remove the extra data: these are values of the spectral data at 360-390 nm and from 710 to 780 nm. Thanks for the update.

Running almost 3 hours: the process is still hanging: Not sure what is causing it: it does not give an error that some data is wrong or corrupted, just hanging. The previous 228-target works flawlessly. But I tried a slightly larger patch count of 247 (one extra row of 19 patches added), but...

I am struggling with the larger 247 patch target. There is not the same error as previous, but running colprof.exe and the system tends to hang without any error message and does not proceed: @x64 : maybe you can have a look at, not sure what is wrong with it and can you produce a profile...

@Epatcola : that is a fantastic design you have made....making it possible to scan miniature patches as well. That will greatly increased the amount of patche on a sheet of A4/Letter.

yes indeed, likewise my i1Pro1 and i1Pro2 white tile also is bound with a seria number to the device and cannot be exchanged, because each tile/spectro combo is factory calibrated to match.

I will try to reread the target again, because maybe the problem is on my side. Normally the distribution of the test samples should be ok, as the targen.exe argument -G is enabled (good distribution). I will give it a try again and report back. Meanwhile I could generate a profile using my...

Mine reads a white point of the tile: 91.22 -1.09 0.17 probably not a concern, as each tile is bound to each individual spectro.

ok today I tried a newer 247-patch target and unfortunately there is an error when executing colprof: The message: warning: colprof: Warning - gammap internal: input bounds has changed !.... @x64 Could it be there is a conversion error from mapping the ti2 file to the csv file to generate...

yes it has a white tile to calibrate on: it is magnetically attached on the spectro.

I think printing a special mall that uses the adjacent patches as kind of reference to clearly define the position of the scanning hole is feasible, but since it can do spot reading only the whole process will take much more time then strip reading. However: the older Spyderprint3 also supports...

I will already upload my new target that has 247 patches of which 21 grey steps included for those interested. It fills up the whole A4 area with 14x14 mm patches completely.

Today I was able to do 3 different combinations with 2 printers and 2 types of papers: Epson SC-P900 with Calumet Matte 230 gsm photo paper Canon TS705 with Action Glossy 210 gsm cast photo paper Epson ET-8550 with Action Glossy 210 gsm cast photo paper Using a 228-patch target that is printed...

Users of the vintage Gretagmacbeth Eye One Pro (X-Rite i1pro1 or EF-1000) need to use a older version of X-Rite i1profiler and that is version 3.1.1 or lower. Any higher versions do not support the i1Pro1. Export in CGAT Spectral data txt format and use txt2ti3.exe to convert it to ti3-format...

Many thanks 🙏👍 @x64 : the only thing is the cr30_to_ti3.py does not function well but the build_profile.py immediately gave me the ti3 file.... My first impression is the profiles generated with the cr30 is very similar in volume and size and shape compared to the ones created with the i1pro1...

ok, I thought I did upload the ti2 file with the set. I will have a look at when I am at home this evening and also will have look at your latest CR30 ti3 dispensary later on to see if I can generate the profile using the ti2 file and my scanned CR30 csv file.

OK many thanks for the update. I am now at work. Could you already upload the profile that is generated from the CR30 scanned csv file, so I can have a look at in iccview.de. It would be better to use the ti2 file, because sometimes reordering the patches (to scrambe patch layout) is better for...
