One thing: since the target is meant for RGB printer profiles, you should NOT enable custom ink limits: this can cause pooling when your paper does absorb that much ink. That function is meant for CMYK printer profiles, where it is very important to determine ink limits.

So if you generate a target for CMYK, then you should enable custom ink limits to see how much ink your paper can absorb if the standard setting is too much for the paper used, because this is for CMYK ink separation. For RGB profiles the ink limit is determined by the media/resolution setting by which the target is printed with. This is the reason why a printer profile is bound to a specific media and resolution setting: so if you have chose the setting: Epson Premium Glossy at standard quality, stick to this setting when printing with this setting, as changing to high quality will likely cause a color cost on your prints, as the amount of ink laid down on the paper will change too.

Custom ink limits are disabled by default. It’s ment for future people on CMYK printers. Futureprof not only for us

And simble gui for making patch targets and scanning. Patch size to final patch number taking to grey patches in mind.

What I would suggest to add an extra option to enable/disable space bars (wether black/white (-b) or colored (-c) ) and also the option to change space bar(-A.xx) width and use 8 or 16 bit resolution for the patches ( -t360 vs -T360: 8 versus 16 bit patches at 360 dpi resolution)

EDIT: I discovered the maximum amount of patches that fits on a sheet of A4 with manual scanning (14x14 mm patch size) with the CR30 is 266: so 14 rows with 19 patches in total. I will upload my latest targets having 21 grey steps included and with 266 patches in total on a single sheet of A4 (210x297 mm).

U can disable, enable spases and use b&w or color, change space width and exporting tif on 8 vs 16 bit is also availabe but for some reason dosnt show in this build my bad. All is available like on cmd line

Here is the 266 patch target for A4 for the CR30 colorimeter:

It has 21 grey steps.

Can u give me whole command that u use for generating tha target? Im trying with gui and i always get rectangle instead of square. On spacing and without them is the same?

Hi Micronica: there is some cheating involved: I use photoshop to stretch and squeeze the whole thing for the patches to become square: this is not possible with printtarg only: you will end with elongated patches as always.
