The late great chemist and inventor John Edwards told me more than once that the European version of the MSDS is more accurate and complete by law than what we allow here in the states, so you might try getting those.

In the past, I looked at the Material Safety Data Sheets for the inks to see what they were doing.  You can Google "Epson [printer model] MSDS" you can usually find these disclosure documents.  They disclose some of ink's compositions.  Unfortunately, there are increasingly errors.  Whether they've been negligent or intentionally try to hide things is an open question.  The problems seem to have become worse in recent years.  You'll notice that the dates on the MSDSs for some old printers are very recent.  I challenged them on the Claria K MSDS.  They agreed it was wrong but never changed the website.

I think a draw down of samples of the inks might be more reliable today.  Printing with them is better, of course, but a draw down is fast.  See http://www.paulroark.com/BW-Info/Draw-Down-Procedure.pdf

  Here is how I understand it:


  The UltraChrome inks don't include the LLK ink. 

  The UltraChrome K3 uses the same K, LK, LLK in the x800-x900 printers but the x880 and up have the vivid magenta/vivid light magenta (and the orange/green inks in the 10 ink printers—but I think they use HDR for the x990 printers with original K3 inks)

  The New UltraChrome HDR have some new Black ink in the P-series printer, but It doesn't say anywhere if the LK/LLK inks are different or just the PK and MK. I can make a few tests next week with a 9900 and the P800 and measure the differences between the LK and LLK inks. 

  All the best,
