OK now trying the standard TC9.18 target (already having alot of stained near neutral ramps): Workflow is now perfect (softproofing no longer strange colours):

OK now trying randomized patch order in order to get maximum color difference between color patches: Randomized with B/W spaces no problem at all, thus we should change from non-randomized with B/W spaces as a default workflow: OK it was succesful: But the softproofing is horrible, so I...

OK, trying to read row Y (on the following page): a cosmetic error: next page is row Y, it says: scanning row z: All rows read, but the marker indicates the previous row being read: With B/W spacers it is better: However the target is not optimal, as the non-randomized layout gives...

I am trying to test the TC9.18 + extended grays target tomorrow. I have already printed the 2 sheets and will scan the targets tomorrow and report back.

Oh that is just a cosmetic fault, Can be easily corrected :lol:

The TC9.18 target is often used by commercial profile companies as the standard target of choice, because it uses an RGB sampling of 9x9x9 and very importantly a good sampling of the near neutrals around the neutral axis. Normally it is often difficult to establish the neutral axis with...

Yes because now the contrast of the text is much better: in the beginning the text color was so light there was hardly possible to read against a white background. I think there was some complaints too on dpreview.com

The reason why I choose the landscape method is the fact that most 3D printers cannot print such large items. I am now printing a new jig especially for this ChromeIQ patch layout.

That would be very good, but I suggest to change the name a bit: "TC9.18 + Extended grays by Pharmacist" Now I have played with the Colormunki/i1Studio method with the triple density method and I could press 324 patches on a single A4 (landscape), which already generates a pretty accurate...

You can give it a try. I am now configuring which type of targets I am going to make for both most used spectro's: Colormunki/i1Studio and the i1Pro1/2. You might have read my post about how much patches are enough for a good printer profile: together with @Ink stained Fingers we came to the...

Not sure, but would it be beneficial to have some my special combined TC9.18 + Extended Greys patchset (Spyderprint) to be used as a standard target that can invoked in the guided method ? The argument of printtarg of "printtarg -ii1 -pA4 -L -a0.95 -m10 -M10 -r -c/b -A0.90" will put this...

Sorry, maybe my slight autistic look at this, but when tell me so I can appreciate it. OK, now I will have a further look at things and test other options....Maybe the heat is also playing a role :lol:

I will have a look at the programmed generated ti1 files and use manual printtarg to see how the finally tif files look like without scrambling: this way the white/black/grey patches will be put on the first rows and we can count. Let's have a look: With the grey ramp reference: 1140 patches...

I don't understand this for the guided mode: I choose for grey ramp reference: 290 patches and get: targen -d2 -G -e6 -B6 -g64 Increasing the amount to 1140 for the "grey ramp reference": I choose for grey ramp reference: 1140 patches and get: targen -d2 -G -e6 -B6 -g16 So I think the...

Strange choice of grey steps based on the patch count reference: When choosing a higher patch count reference, the amount of grey steps drops instead of increasing: For 560 patch count reference: 33 grey steps Increasing the patch count reference to double 1140 the grey steps decreases to...

So I tried the neutral axis argument (-n64) again and this time I see clearly the colored (purplish) grey patches after the grey patches row (-g64), based on the reading of the initial preconditioning target. I tried to load a special ti1 file that is based on the TC9.18 combined with the...

Thanks for the update. I did not see the warning tab 😕

The preconditioning function in the manual option does not work. I tried 64 neutral steps in manual, but it does not appear in the targen window: In the guided mode: There is -n33 (neutral steps, I believe Sebastian uses this amount as standard). Unfortunately it not available in the manual...

I am impressed. What I am actually doing now is a deluxe version of the Colormunki/i1Studio 50 + 50 patch method, but now I am using 336 patches for the initial profile/target and from the first reading it generates and estimates the neutral axis for which it generates new measure points to...

Yes it works: Now I have to see softproofing in PS using the initial profile (upper print) and the optimized profile (lower print): Maybe a bit distorted, because the real world result here is way more neutral in the greys for the optimized profile (using the preconditioning method). The...
