Yesterday I created an A5 target with 384 randomized 8mm patches. I printed it on half an A4 sheet of Epson Premium Glossy paper on an ET-7750. I measured the target this morning which took nearly 20 minutes. I am sure with practice and a bit more care that could be reduced. Aligning the rule...

I am using 8mm patches and the rule I designed so you only need to see a couple of patch 'joints' to align the rule. I have never had any ti3 files from chartread to look at. It appears the colprof needs the input RGB values (from the ti2 file) followed by measured values on each data line. I...

Today for the first time I printed and measured a target. The target was randomized and I couldn't generate a profile. I think the build_profile script is not doing the right thing. The patches are randomized on the sheet and the ti2 file has a SAMPLE_LOC to tell you where they are on the...

Something is messed up. I don't know what your .colors file is. I generated an A5 10mm patch target from your 228 ti1 file with this printtarg.exe -r -v -i 22 -p 148.492x210 -a1.25 -T360 -m3 "my 228-target" and got this Which doesn't look like your photos. The 4th patch (A4) in the ti1/ti2...

I have not tried generating a profile yet. I have an i1studio so I don't really need to. I bought the CR30 because it is cheap and interesting and could be convenient for spot reading. I was/am waiting for the scripts you guys are producing to be finished and stable then I will probably have a...

The target is straight out of printtarg. No need to edit. All you need is something that can print without color management and to scale obeying the 360DPI file resolution. I use Qimage. I played around some more with printtarg and -i22 is the best instrument setting for square patches. If you...

This targen -v -d2 -g 16 -f 486 test printtarg -r -v -i 22 -p A4 -a 1.2506 -T914.4 test produces 486 x 10mm square patches on an A4 sheet: The instrument type parameter seems to control the shape of the patches and peripheral annotations. The -a parameter scales the patch size. I didn't look...

Here is a collar and 300mm rule for 10mm square patches. Rule and collar on your 247 patch target scaled by forced printing at 518 dpi. Align the rule to the edge of the patches with notches central. Press the button and slide to the next notch. I can't see how that isn't faster and less...

I noticed the calibration cap has a serial number matching that which the device reports to the application. Our white calibration values differing shows the device has has a factory calibration for itself and associated calibration cap.

With a collar like I suggested and a patch pitch notched rule you would only have to align the rule for each column the CR30 would just be slid along to the next notch. My calibration patch reads 89.44 -0.71 0.12 (D65 source) is yours the same? The documentation is pathetic. I just noticed...

Thanks both for the work you have done on this device. I had a CR30 delivered today. I think with care you could go smaller than 15mm square patches. The hole in the bottom of the CR30 is only 5mm. If I do end up using the CR30 for printer profiles I think I would print a collar for it...

The CR10/20/30 are at the bottom of the page I linked. I assume they are the manufacturer or at least closer to them than aliexpress and so a good source for documentation and software. The link to windows software for the CR series seems broken. I guess it is common to some of the other...

The file says NUMBER_OF_FIELDS = 7 while the DATA_FORMAT statement has 8 fields. 228 * 7/8 = 200 Looks like it just reads data elements according to the data format ignoring new lines. Are you sure argyll needs RGB and XYZ values anyway? If you can generate them from Lab then argyll could as...

I'm sure the posts here will contribute in a small way to information AI bots trawl from the internet and regurgitate so eloquently. That doesn't stop me hiding (under a VPN for starters). The less google (the biggest and worst collector and correlator of personal information) know about me...

The most likely money grab is tying the hardware device to particular computers (which requires an internet connection to orchestrate) and restricting the number of computers and displays that can be calibrated without additional payment. I think the spyder display calibrators are already...

I'm not sure what you mean in the last paragraph. OS Updates might break screen calibration with older software. I'm sure I will still be able to profile printers running older software in an older OS running in a VM. I never tried the Colormunki Photo software. I have argyll installed in a VM...

Heads up. Calibrite have released their Profiler software/driver package version 3.0 which now includes printer profile creation. They have removed the ccStudio download so they expect you use Profiler 3.0 and for any Xrite supplied devices pay an update fee which is (IMO) a rip off GBP 60 for...

Nozzles don't randomly block and unblock themselves on every nozzle check/clean cycle. When you say deep clean i assume you mean the second clean cycle offered when you say a nozzle check failed. The word 'deep' does not appear in the printer manual. If you get a bunch of (or all)...

I would be tempted to stick a sheet of paper on the bottom of the tray, possibly removing the bottom 0.3mm of the model first. I think the polished steel paper feed roller will grip paper better than PLA. I would also look at where the pinch rollers for the paper feed roller bear on the tray...

You don't mention so it sounds like you missed the driver preferences having a settings button next to the borderless checkbox which offers retain size and auto expand options. That is on windows. I don't know about mac.
