Looks as if the problem is in your version of CAP480.bat. The targen parameter -d4 will give you CMYK; sure enough your .ti1 file is CMYK. Change that parameter to -d2 and you will get RGB.

You are so right!!! I changed to -d2, now the .tif file generated is in RGB mode.
And if later we plan to make another icc profile, we just delete the .ti3 > print the 480 .tif targets with another printer > read without going through step one generating .ti1?

I also resize the patches in A4 .tif files in Photoshop without any other changes, but I also noticed the size increase double from 2-3MB to around 6MB, is this normal?

Anyway, when will -d4 be useful? And is this CMYK that make my print so dark?

The CMYK profile that you generated is pretty awful! Your printer is an RGB device and I can't begin to guess what happens when you feed it an RGB file and force it to use a (bad) CMYK profile.

As for when -d4 is useful, I would say, for anyone using the OEM printer driver, never! Stay well clear of CMYK.

@RogerB , I tried #2 in 'ArgProf#2.bat', it worked great.
Anyway, last time it came up with one color patch 'W' which doesn't matter how many time I tried, it showed reading inconsistent which didn't happen with the rest of the patches till AC (I am using 480). Is this the error of the print or sth else related?

I remembered last time you helped generating the profile for me from the .ti3, and that I also skipped one row, but the color printed came out fine.

Any advice for this please?

I'm pleased that the batch file is working well for you - even if we did have to modify a few parameters in the Argyll commands!

Difficult to say why one patch should should cause problems. It may be because the printed colour is too far away from the expected value or possibly because there is not enough difference between the colour of the patch and that of the adjacent patch. Can you post the tiff file for your target image and point out the problem patch?

I had to skip 'W' patch. From the generated profile, GamutVision doesn't really show any bad color? https://www.dropbox.com/s/ghbdsueck3v4gtz/EPSON_T1100_PremiumMatte_soweic Sun 11-22-2015.icc?dl=0

It's not obvious to me why you have trouble with row W and not others. However, looking at your profile I see a very small colour gamut which means that all saturated or dark colours will be degraded. This may make it difficult for Argyll to recognise the measured colours because they are just so far from what it expects to see. Are you using plain paper for this?

Just got informed that it is the transfer matter paper. Maybe this is why measuring on paper is not going to get the right gamut until we transfer it to the t-shirt and measure from there?!

Has anyone tried with kraft (brown) paper? The colormunki refused to read with Argyll and it also won't read the last (5th) row in its native program.
I tried a few prints and it's all the same, but with the white paper, it's working just fine!!!

Argyll expects to start and finish each measurement row with white, try fixing a strip of white paper over each end. I don't know if it will work.

I see you have added a clip on ruler guide to your measuring mask, do you find it helps?

Yes, I also tried putting two white sheets at the bottom and top, it still couldn't get passed. And what strange to me is why it can go fine with the first 4 stripes?!
P.S: Also emailed support of x-rite, they keep insisting I need to print on white whereas I am to work with color paper

And about the clip, it's just there to hold the ruler and keep it from sliding.
