Yesterday I received a cheap aliexpress colorimeter that measures patches on surfaces and it gets only LAB-values registered. Is there somebody here, who is capable to convert this csv file into a CGAT compatible value so it can be converted to a ti3 file. My idea is to use this cheap colorimeter as a poor man's spectro to generate printer profiles. I already created a 228 patch target with 1.4x1.4 cm large patches so the target can be easily read with this colorimeter. The device can read D50/D55/D65 etc including with/without UV included so I think with the right software and conversion it should be capable device to do so. All help is appreciated. I will upload the files this evening.

From the luminous landscape website I have found this:

Good day.
Thank You everybody for answers.

I got RGB value from my .ti2 file and inserted in .ti3 file and add my measured lab data (by Excel):

CTI3

DESCRIPTOR "Argyll Calibration Target chart information 3"
ORIGINATOR "Argyll printread"
CREATED "Tue Aug 20 19:16:40 2019"
DEVICE_CLASS "OUTPUT"
COLOR_REP "iRGB_LAB"

NUMBER_OF_FIELDS 7
BEGIN_DATA_FORMAT
SAMPLE_ID SAMPLE_LOC RGB_R RGB_G RGB_B LAB_L LAB_A LAB_B
END_DATA_FORMAT

NUMBER_OF_SETS 441
BEGIN_DATA
1 "A1" 47.45098 23.13725 0.00000 25.13 10.5 14.31
2 "A10" 57.64706 17.64706 38.43137 24.51 21.49 -2.15
3 "A11" 0.00000 59.60784 48.23529 21.54 -24.67 -17.43
....
END_DATA


and built profile without error.

Another way is use argyll fakeread tool and
create a .ti3 file from .ti1 file, and paste L*a*b* values into the .ti3 file.

I hope it is correct :)

------------------------------------

So essentially I have to use fakeread.exe to generate a dummy ti3 file and paste the LAB data of my el cheapo colorimeter generated csv file into this ti3 file and generate the target. I will give it a try this evening and report back and if succesfull I will compare it with a profile made with the more advanced i1Pro2 with the same ink/printer/paper combination. Finger crossed....
