Same target: scanned by both Colormunki and i1Pro2, differences in profile quality ?

The gloss does not look different at all: I looked especially on the black patches and the same gloss. This really intriges me

For sake of comparison I will print the same target on my Epson ET-8550 (no black enhance overcoat whatsoever) and will generate a new target this evening after drying.

'To print by increasing black density, use black enhance overcoat in the printer driver.' This is apparently not happening - one way or another - Epson claims that there should be some difference.

Which program are you printing with ? Could it be that there is some hidden change of parameters - BEO - behind the screen caused by that software ? Could you print the target with some other software - Epson ? - alternatively ?
and I see some carbon black option and gloss smoothing - how would they impact the black level together with the
BEO option ?

I am using photoshop using native Epson P900 driver to control (disabling) color management. I will first try the ET-8550 target and see if the reading error is not in the i1Pro2. The ET-8550 should have lighter black level. On the P900 it is not even carbon black (maximum resolution setting), so it might be even blacker when choosing that option.

Here is the ET-8550 profile using the same target and i1Pro2.....definitely a higher black level.

i1Pro2 is not defective.

The dye-pig comparison target reports a black level for the dye print of L= 4.3 1.06 -7.31, that's a very good black level as well, not every ink/paper combination reaches such level. the b-level with -7.31 is typical for dye blacks showing a cool blue touch.

The gamut of the dye-print overall is somewhat larger than the gamut with the pigment inks , here a cut a mid-luminance of L=50

Orange indicates the dye-gamut and the yellow line the gamut border of the pigment ink gamut.

Anyhow, despite the strange, but very good black level on the P900 without a noticeable difference between BEO or not BEO, the conclusion is that the independent scanning with both the Colormunki/i1Studio and the more advanced i1Pro2 gives similar quality profiles.
