How to use an unlicensed i1Pro spectro with i1Profiler and ArgyllCMS

here you are. You will surprised how good this small target is: you can hardly tell the difference with the larger patch sets.

Thank you very much @pharmacist i will have a lot to test in Christmas time:
- some ancient HP Baryte Satin Art Paper (it tells for pigment inks, but i will try with dye) i have in A3+, 610mmx30m rolls and 1118mmx15,2m rolls
- some old A3+ Arches Textured Cotton paper (i suppose it is Hahnemuhle paper)
- a lot of Fujifilm Fuji Hunt professional Paper in rolls, Semigloss, Glossy, Matte and Luster
- a lot of Epson Paper in A3+ and rolls Semigloss and Luster
and a lot of others A3, A4 and rolls, some unknown too

i don't know if i will have the time to make all the profiles, but i wanna try, your ruler and iProfiler, maybe i can have better feedback when scanning so i can get the best way to do it.

When i will have some time i would like to know how you generate these target sheets, which software are you using (ArgyllCMS or Xrite software) ?

If Argyllcms i would like to see your parameters, just to understand how to create them, i would like to create target like Keith Cooper does, with a row with a lot of Green gradients from low to high, Yellow, Orange, and almost all colors, more a white,black,grey gradients rows.

I don't how many patches will be required, but i can't find an option in ArgyllCMS to do it easily, the other problem is that if i run the generator several times, each time i will get a different target patches set, maybe i have to use a switch that don't use random, but i don't know how.

@pharmacist today i tried to use your enlarged ruler (we used a value to increase the length) to scan using i1profiler v3.1.1 for Mac with my i1pro (EFI-1000) but with no success,

I could read 24/25 patches versus 27 of each line, the ruler is not long enough to permit the read of all the patches on a row (the hole for the sensor is right, but the channel base for the rear is too short, it doesn't permit to the i1pro to reach the white spaces at the end of the sheet), so maybe i will need less patches maybe larger (so the scanning has more readings for a single patch) and more white space at the edges of the A4 portrait.

Maybe could be also a bad scanning method, i don't scan patches from months, but i would like to give a try with bigger and less patches with more white spaces on edges.

So if you have some time and you can create another set of 700/800 patches for an A4 in portrait maybe i can try again

Tell me first the maximum distance you have between white and white area using the ruler and tell me the distance for example 24 cm, so I can make a target for you.

The area is exactly 22.3 cm as my design takes into account the scanning eye will start en stop on white paper and in between the row length must be 22.3 cm long:

the big window is 20cm large (why so short if i enlarged your project ?), so i suppose is this the problem.

the sensor window is 21,2cm large

but for now i can't reprint the 3d model, my printer is off we need to fix it

if you see the image, instead i can't reach the left and right white spaces when i reach all left or all right with bottom of the i1pro, the top sensor stops in line with the bottom of the ruler but it hasn't enough space to reach the left/right white spaces, i could rotate left or right the top to reach the white spaces, but it doesn't seem work right

don't take this sheet seriously, it's a simple test on normal paper

Can you tell the hole measurements ? From your photo your hole seems wider than mine

maybe my hole is not enough wide

 

[pharmacist]

My scanning eye opening is 25.5 cm wide, so not sure how much the width is of your scanning jig ? Here is a new design I made. I hope your 3D-printer can print this size.

Meanwhile I have shrinked the target a bit in order to fit your smaller scanning guide. BUT you have to move slowly now in order to pick up enough sampling points as the patch width is now very critical.

See picture here: left the original target and on the right the shrinked version so hopefully your scanning guid will encompass the whole area:

ok thanks for the new ruler but i will need to fix my 3d printer before

i mean not in the long side, but in the sort side, anyway my ruler is 21,2 cm in the long and 6mm in the short side
