I tried to have a look at the program, but I think some settings are based on the directory structure of MacOS (Unix): See the yellow warning exclamation symbols on the top. I tried the i1Pro method and the 960 patch version, but I think the layout is too elongated having no white gap at the...

I printed an evaluation target using both profiles and scanned both print outs with my calibrated scanner (ET-8550): Which on is printed with the profile created with the unsupported WF-7840 and which one with the supported ET-8550 profile ?

Softproofing with both profiles in PS (RC, BPC=on):

OK here is the second test using a different paper/ink/printer combination: Action Glossy (cast paper) on the ET-8550 dye ink printer: First on the dedicated and supported ET-8550 scanner: Here is the version on the unsupported WF-7840 scanner: Note the above bump on the right side of...

I have printed the target on a cheap cast paper of Action with the ET-8550, which should give a different 3D plot. I will redo the test this evening and see if the profile is similar using both the ET-8550 (supported) and the WF-7840 (non-supported) scanners.

Redoing the test with an earlier printed target on another paper type: First on the ET-8550 scanner: Secondly on the WF-7840 scanner: Here is the iccview.de 3D plot: Using both profiles in softproofing mode beneath: left original picture, upper right: softproofed with the ET-8550...

I have to test this, but my first impression that by chance I tried to make a profile with PrintPrism with my unsupported Epson WF-7840 AIO scanner using the built-in ET-8550 scanning engine: The scan histogram seems to be very healthy and this is the 3D plot in iccview.de with the same...

That is strange: I tried to use my Epson WF-7840 scanner if it would give a good profile (officially not supported) and to my astonishment the profiles are almost the same: I tried the WF-7840 printer as scanner and using the ET-8550 scanning engine in PrintPrism: Beneath softproofing with a...

OK good to know. So you use the ET-8550 scan engine of the PrintPrism to generate the profile. Maybe Mike Chaney would be pleased that the XP-970 scanner has the same results because it uses the same scanning engine.

A cheap scanner supported by PrintPrism is the Canon Lide 300 (about 70 euro).

@ohtoulouz Here I have a 560 patch target for the CR30 that needs 2 sheets of A4 to be printed and should be more accurate.

Colormunki works perfectly without any problems with the ccStudio or i1Studio software, no reason to pay for the latest software: it doesn't give you better results at all.

Did you tried a different rendering intent like perceptual intent with BPC enabled ? Normally 300 patches will already do a good job. Sometimes choosing another intent can improve print quality. Normally 51 is a good maximum for grey steps.

I would start with my 300 patch target. I have tested the profiling making with 3 printers: dye printers like the Canon TS705 and the Epson ET-8550 and the pigment photo printer Epson SC-P900 using different papers, like glossy, satin and matte and all prints look more and less the same (within...

spectral band between 400-700 nm is almost the same as the much mor expensive i1Pro2: 380-730 nm. The reason why this small device does such a great job in creating printer profiles.

Mine behaves the same: nothing to be worried about. Anyhow I am glad you managed to get your first printer profile using my 300 patch target. I have done this several time and everytime I am amazed how good this CR30 spectrophotometer is and it is very cheap: About 1/8 of the price of the...

Don't use the BlueTooth method only USB. Normally after a reading you will hear a sound (beep): release only from the paper surface after you have heard this sound, otherwise you might get a read erro.

My Windows computer says NOOO....cannot have a look at it, Apple only.

Just to say my 572 patch target is also generated with the pkpatches tool like you did thus similar results as expected with the targen command as engine.

If you have license for i1Profiler: what you can do for more neutral profiles is in the profile settings (after you have scanned the patches): Set neutralize grays at 50% (normally at 0 %), which will enhance neutrality significantly.
