With some manipulation and the dedicated work of @crenedecotret I managed to manipulate the famous TC9.18 target (from X-Rite i1Profiler) and which is indeed considered as the gold standard target for RGB printer targets to be compatible with ArgyllCMS and the i1Pro2 spectro + scanning table.

The patches are randomized before I made this manipulated target so you will have a better ergomical scanning experience by aligning the target towards the right border of the scanning table: the i1Pro2 scanning eye will stop exactly on the white area at the end of the row and before the corresponding letter of the row you are scanning.

The TC9.18 is a bit old but i'm curious to see if it will give good or similar results compared to just letting Argyllcms determine the patches.

I noticed that the TC918 doesn't seem to include much in the way of neutral. At least not at a quick glance. I built another three page target (enlarged i1 size) that combines the TC918 and Spyderprint grays. If you modify it, the last 167 patches in the ti1 are just there to fill my third sheet

This last patch I think completes the series. I kept the Spyderprint gray patches but instead of using the 225 patchs from the color spyder chart, I let ArgyllCMS 644 patches patches including some grays.

With an enlarged i1 size patch, it can still be scanned in with a Colormunki using a ruler and will fit two letter sized sheets

There's maybe the datacolor 729 patch set that I could look at but extracting the RGB values is a pain. The TC918 and Atkinson targets had publicly available data for them.

Here is my combined target (randomized): Spyderprint 225 high quality target + grays into a single sheet A4 that can be scanned by both the Colormunki Photo/i1Studio (with a scanning jig) and the i1Pro2 device optimized for the i1Pro2 scanning table based on the ti1-file generated by @crenedecotret .

Thank you for your work. I will try to manipulate the patches to be a bit smaller and optimize it for the i1Pro2 with my ergonomical layout for scanning. It should be possible to reduce it to just 2 sheets of A4, which will save paper.

@crenedecotret :

I have done the modification for the i1Pro2 scanning table and the 3 page layout has been reduced to only 2 pages (The TC9.18 version is already squeezed down onto a single A4 sheet). Scanning is only possible with the i1Pro2.

Can you make a new ti1 file but only the TC9.18 combined with the SpyderPrint grays layout, but without the last 167 extra patches to fill up your third page ? The reason is that I can modify the target down to only 2 pages of A4, using sligtly larger patches.

Today I printed the modified TC9.18 target for ArgyllCMS on Netbit paper with my ET-8550 printer and used ArgylllCMS to create the profile:

The last image shows the target confines the movement of the i1Pro2 to stop exactly on the white area on of the target on the right side. I always modify my targets to behave like this for the sake of ergonimical scanning.

This is the printer profile based on the TC9.18 target that has been converted to ArgyllCMS by @crenedecotret :
