Printprism: I have bought it to test its capabilities and quality of the rgb profiles

Yes, I know. But space on my desk is limited ! By the way, I bought PrintPrism and made profiles with the XP-970 and the result is excellent. Specifications of XP-970 et ET-8500 scanners are exactly the same on Epson website: I am pretty sure they use the same hardware.

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.

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 PrintPrism generated profile: left with my Epson WF-7840 (not supported) and right with the supported ET-8550....They look similar to me.....

Now the 3D plot on iccview.de:

test.icc is the profile made with the officially not-supported WF-7840 scanner:

This is very surprising to me....Could it be the WF-7840 is using the same scanning hardware als the officially supported ET-8550 ???

Yes, exactly. There is no scanner restriction. I choose Printprism ET-8500/8550 option and when the Scan2 window open, I choose XP-970 scanner. Problem is I cannot compare my results with those of an approved scanner. I just can tell that the results with XP-970 are good. I do not know if they are as good as possible unless I buy a Canon Lide 300 or an Epson V39II. So maybe it is too early to tell Mike Chaney to put the XP-970 on his list of approved scanners.

I am sure that there is not that much different scanner hardwares around ! Business is business. If one hardware fits all, it is all benfit for the company !

However, looking at the spec Of the WF-7840 scanner on the Epson website, it not execaly the same specs: (2400dpi max instead of 4800). But it does not mean that the hardware is different.

I own a copy of SilverFast Studio AI 9 that I use with an Epson Perfection 600 scanner. It uses a it.8 Version 2 target for a reference prior to scanning for a printer profile. Not a cheap software with the it.8 target, maybe $400.

I also bought a Canon LiDE 300 scanner and Print Prism given the hype.

Honestly, the Print Prism produced a better test image than the SIlverFast Studio AI did, and was significantly cheaper too. The SIlverFast needed an edited profile as the ring-around color test patches were off a lot. The edited version was no better. A third edit version to correct it was no better either than the first one out of Print Prism.

Print Prism was very fast, less paper and ink waste for the test, and easy to use.

Later, I just made a print profile from a 3rd party dye ink (BCH) loaded into one Epson 3880, and the normal pigment ink in the other 3880 made using Print Prism. The dye ink was larger color gamut in the wireframe than the pigment ink, which I sort of expected as shown below.
