Wow, the 4800 and 2100 prints on Premium Semigloss two are so VERY close it's amazing. Very hard to pick the difference at an arms length, certainly not by color alone. The 4800 print is slightly more neutral - the 2100 print warm, but well within acceptable range. The color swatches look very similar - nothing in particular stands out as radically different, if anything the 2100 print is every so slightly more saturated.

The blotchiness in the 2100 blacks I mentioned on Velvety isn't apparent in the 2100's print on Epson's Semigloss. The 4800 print is holding slightly more detail in the darker tones though e.g. the red area I outlined earlier (the cogs towards the top left), not a huge amount - but noticeable, very clean. The 2100's is a little murky by comparison.


Gloss differential is far more pronounced on 2100 print - esp around the children's heads. It is present in the 4800 print but to a far lesser extent.

Bronzing and metamerism I'll look at later.

Known problems aside, these prints are VERY close - to be honest I thought there might be larger differences. Having identified small differences I can now readily pick which print is which (if I'm looking closely at the print), but it is very close at arms length and moreso at a viewing distance.

In progress conclusion - if you're expecting vastly improved color out of the 4800 over the 2100 you may be looking in the wrong place. I think it's going to take some time and effort to eek out significant improvements re color on the 4800 over the older Epsons.
